There was a little white table spread with pink-frosted cookies! There were great crackly glasses of raspberry vinegar and ice! Old Mary had on a white apron!–That’s why we laughed! We _knew_ we were expected!

My Father explained it to everybody.

“As long as Carol couldn’t speak his piece,” he said, 9L0-827 Exam “It didn’t seem fair that any of the children should speak ‘em! So the children have all written their pieces to read aloud and—-”

“But as long as Carol wasn’t able to read his aloud,” cried my Mother, “it didn’t seem fair that any of ‘em should read theirs aloud! So the children’s father is going to read ‘em. And—-”

“Without giving any clue of course,” said my Father, “as to which child wrote which. So that you won’t be unduly influenced at all–in any way by–gold-colored hair, for instance or–freckles—-”

“Or _anything_!” said my Mother.

“U-m-m-m,” said the Blinded Lady.

“Understanding of course,” said my Father, “that we ourselves have not seen the papers yet!”

“Nor assisted in any way with the choice of subject,” said my Mother. “Nor with the treatment of it!”

“U-m-m,” said the Blinded Lady.

“I will now proceed to read,” said my Father.

“So do,” said the Blinded Lady.

My Father so did.

He took a paper from his pocket. He cleared his throat. He put on his eye-glasses. He looked a little surprised.

“The first one,” he said, “seems to be about ‘Ginger-bread’!”

“_Ginger-bread?_” said the Blinded Lady.

“Ginger-bread!” said my Father.

“Read it!” said the Blinded Lady.

“I will!” said my Father.

Ginger-bread is very handsome! It’s so brown! And every time
you eat a piece you have to have another! That shows its
worth as well as its handsomeness! And besides you can smell
it a long way off when you’re coming home! Especially when
you’re coming home from school! It has molasses in it too.
And that’s very instructive! As well as ginger! And other
spices! The Geography is full of them! Molasses comes from
New Orleans! Spices come from Asia! Except Jamaica Ginger
comes from Drug Stores! 9L0-827 Braindump There are eggs in ginger-bread too!
And that’s Natural History and very important! They have to
be hen’s eggs I think! I had some guineas once and they
looked like chipmunks when they hatched. You can’t make
ginger-bread out of anything that looks like chipmunks! It
takes three eggs to make ginger-bread! And one cupful of
sugar! And some baking soda! And—-

“Oh Tush!” said the Blinded Lady. “That isn’t a picture! It’s a recipe!–Read another!”

“Dear me! Dear me!” said my Mother. “Now some child is suffering!” She looked all around to see which child it was.

Carol kicked Rosalee. Rosalee kicked me. I kicked Carol. We all looked just as queer as we could outside.

“Read _on_!” thumped the Blinded Lady.

My Father read on.

“This next one,” he said, “seems to be about Soldiers!”

“Soldiers?” said the Blinded Lady. “Soldiers?” She sat up very straight. She cocked her head on one side. “Read it!” she said.

“I’m reading it!” said my Father.

The most scrumptious sight I’ve ever seen in my life is
Soldiers Marching! I saw them once in New York! It was
_glorious_! All the reds and the blues and the browns of the
Uniforms! And when the Band played all the different
instruments it seemed as though it was really _gold_ and
_silver_ music they were playing! It makes you feel so
brave! And so unselfish! But most of all it makes you wish
you were a milk-white pony with diamond hoofs! So that you
could _sparkle_! And _prance_! And _rear_! And _run away_
just for fun! And _run_ and _run_ and _run_ down clattery
streets and through black woods and across green pastures
_snorting fire_–till you met more Soldiers and more Bands
and more Gold and Silver Music! So that you could _prance_
and _sparkle_ and _rear_ and _run away_ all over
again,–with _flags flying_!

We children all opened our eyes and ran home!

My Mother laughed to see us fly!

My Father laughed a little!

We thought about the Peacock as we ran! We thought quite a little about the Ginger-bread! We wished we had a Peacock! We hoped we had a Ginger-bread!

Our Home looked nice. It was as though we hadn’t 9L0-624 Braindump seen it for a long while. It was as though we hadn’t seen anything for a long while! The Garden didn’t look like Just a Garden any more! It looked like a _Bower_! Carol’s tame crow came hopping up the gravel walk! We hadn’t remembered that he was so black! The sun through the kitchen window was real gold! There _was_ Ginger-bread!

“Oh dear–Oh dear–Oh _dear_!” said Rosalee. “In a world so full of beautiful things–however shall we choose what to tell the Blinded Lady?”

Carol ran to the desk. He took a pencil. He took a paper. He slashed the words down. He held it out for us to see.

“I know what I’m going to choose,” said the words.

He took his pencil. He ran away.

Rosalee took her pencil. She ran away. Over her shoulder she called back something. What she called back was “Oh Goody! I know what _I’m_ going to choose!”

I took my Father’s pencil. I ran away. I didn’t run very far. I found a basket instead. It was a pretty basket. I made a nest for the White Kitten in case I should win it! I lined the nest with green moss. There was a lot of sunshine in the moss. And little blue flowers. I forgot to come home for supper. That’s how I chose what I was going to write!

When we woke up the next morning we all felt very busy. It made the day seem funny.

It made every day that happened seem funny.

Every day somebody took somebody’s pencil and ran away! My Mother couldn’t find anything! Not children! Not pencils!

Rosalee took the Dictionary Book besides.

“Anybody’d think,” said my Father, “that this was a Graduation Essay you were making instead of just a simple little word-picture for a Blinded Lady!”

“Word-picture?” said Rosalee. “What I’m trying to make is a Peacock Feather Fan!”

“I wish there were three prizes instead of two!” said my Mother.

“Why?” said my Father.

Carol came and kicked his feet on the door. 9L0-827 His hands were full of stones. He wanted a drink of water. All day long when he wasn’t sitting under the old Larch Tree with a pencil in his mouth he was carrying stones! And kicking his feet on the door! And asking for a drink of water!

“Whatever in the world,” said my Mother, “are you doing with all those stones?”

Carol nodded his head that I could tell.

“He’s building something,” I said. “Out behind the barn!–I don’t know what it is!”

Carol dropped his stones. He took a piece of chalk. He knelt down on the kitchen floor. He wrote big white letters on the floor.

“It’s an Ar–Rena,” is what he wrote.

“An Arena?” said my Mother. “An _Arena_?” She looked quite sorry. “Oh Laddie!” she said. “I did so want you to win a prize!–_Couldn’t_ you have kept your mind on it just a day or two longer?”

It was the longest week I ever knew! It got longer every day! Thursday was twice as long as Wednesday! I don’t seem to remember about Friday! But Saturday came so early in the morning I wasn’t even awake when my Mother called me!

We went to the Blinded Lady’s house right after dinner. We couldn’t wait any longer.

The Blinded Lady pretended she was surprised to see us.

“Mercy me!” she said. “What? Have these children 9L0-827 Dump come again? Muddy feet? Chatter? And all?” She thumped her cane! She rocked her chair! She billowed her skirts!

We weren’t frightened a bit! We sat on the edge of our chairs and laughed! And laughed!

It didn’t make my Father laugh.

“Now see here, you young Lunatics,” said my Father. 9L0-624 “If you think your Mother and I are going to drag you up the main village street–acting like this?”

We were sorry, we explained! But it _had_ to be!

When we got to the village street we bumped right into the Old Doctor. We bumped him pretty hard! He had to sit down! I climbed into his lap.

“Of course I don’t know that it’s _you_,” I said. “But I think it is!”

The Old Doctor seemed pretty astonished. He snatched at my Father and my Mother.

“Great Zounds, Good People!” he cried. “What fearful calamity has overtaken your offspring?”

“Absolutely nothing at all,” said my Father, “compared to what is _going_ to overtake them as soon as I get them home!”

“We’re playing _blinded_,” said Rosalee.

“We’ve been to see the Blinded Lady!” I explained.

“We’re going to get prizes,” said Rosalee. “Real prizes! A Peacock Feather Fan!”

“And the Choice of Cats!” I explained.

“For telling the Blinded Lady next Saturday,” cried Rosalee, “the prettiest thing that we’ve ever seen!”

“Not just the prettiest!” I explained. “But the most preciousest!”

“So we thought we’d shut our eyes!” said Rosalee. 9L0-624 Dump “All the way home! And find out what Sight it was that we missed the most!–_Sunshine_ I think it is!” said Rosalee. “_Sunshine_ and all the pretty flickering little shadows! And the way the slender white church spire flares through the Poplar Trees! Oh I shall make up a picture about _sunshine_!” said Rosalee.

“Oh, Sh–h!” said my Mother. “You mustn’t tell each other what you decide. That would take half the fun and the surprise out of the competition!”

“Would–it?” said Rosalee. “Would it?” She turned to the Old Doctor. She slipped into the curve of his arm. The curve of his arm seemed to be all ready for her. She reached up and patted his face. “You Old Darling,” she said. “In all the world what is the most beautiful–est sight that _you_ have ever seen?”

The Old Doctor gave an awful swallow.

“_Youth!_” he said.

“Oh, youth Fiddle-sticks!” said my Father. “How ever would one make a picture of _that_? All arms and legs! And wild ideas! Believe me that if I ever once get _these_ wild ideas and legs and arms home to-day there will be—-”

We never heard what there would be! ‘Cause we bumped into the Store-Keeping Man instead! And had to tell _him_ all about it!

Nobody kissed the Store-Keeping Man. He smelt of mice and crackers. We talked to him just as we would have talked to Sugar or Potatoes.

“Mr. Store-Keeping Man,” we said. “You are very wise! You have a store! And a wagon! And a big iron safe! And fly-papers besides!–In all the world–what is the most beautifulest thing that you have ever seen?”

The Store-Keeping Man didn’t have to worry about it at all. He never even swallowed. The instant he crossed his hands on his white linen stomach he _knew_!

“My Bank Book!” he said.

My Father laughed. “_Now_ you naughty children,” said my Father, “I trust you’ll be satisfied to proceed home with your eyes open!”

But my Mother said no matter how naughty we were we couldn’t go home without buying pop-corn at the pop-corn stand!

So we had to tell the Pop-Corn Man all about it too! The Pop-Corn Man was very little. He looked like a Pirate. He had black eyes. He had gold rings through his ears. We loved him a good deal!

“In all the world–” we asked the Pop-Corn Man, “what is the most beautiful–est sight that you have ever seen?”

It took the Pop-Corn Man an awful long time to think! It took him so long that while he was thinking he filled our paper bags till they busted! It was a nice bustedness!

“The most beautifulest thing–in all zee world?” 9L0-624 Exam said the Pop-Corn Man. “In all zee world? It was in my Italy! In such time as I was no more than one bambino I did see zee peacock, zee great blue peacock stride out through zee snow-storm of apple-blossoms! And dance to zee sun!”

“O–h,” said Rosalee. “How pretty!”

“Pretty?” said the Pop-Corn Man. “It was to zee eyes one miracle of remembrances! Zee blue! Zee gold! Zee dazzle! Zee soft fall of zee apple-blossoms!–Though I live to be zee hundred! Though I go blind! Though I go prison! Though my pop-corn all burn up! It fade not! Not never! That peacock! That apple-blossom! That shiver!”

“Our supper will all burn up,” said my Mother, “if you children don’t open your eyes and run home! Already I _think_ I can smell scorched Ginger-bread!”

“Why I’m sure,” said my Father, “we never would have come at all if we hadn’t supposed that—-.”

The Blinded Lady shook her cane right at my Father.

“Don’t be stuffy!” she said. “But get out!”

We got out.

Old Mary who washed and ironed and cooked for 9L0-623 Dump the Blinded Lady showed us the shortest way out. The shortest way out was through the wood-shed. There were twenty-seven little white bowls of milk on the wood-shed floor. There was a cat at each bowl. It sounded lappy! Some of the cats were black. Some of the cats were gray. Some of the cats were white.

There was an old tortoise-shell cat. He had a crumpled ear. He had a great scar across his nose. He had a broken leg that had mended crooked.

_Most_ of the cats were tortoise-shell _and_ black _and_ gray _and_ white! It looked pretty! It looked something the way a rainbow would look if it was fur! And splashed with milk instead of water!

“How many quarts does it take?” said my Mother.

“_Quarts?_” said Old Mary. She sniffed. “_Quarts?_ It takes a whole Jersey cow!”

The Blinded Lady called Rosalee to come back. I went with her. I held her hand very hard for fear we would be frightened.

There was a White Kitten in the Blinded Lady’s Lap. 9L0-623 Exam It was a white Angora. It wasn’t any bigger than a baby rabbit. It had a blue ribbon on its neck. It looked very pure. Its face said “Ruthy, I’d like very much to be your kitten!”

But the Blinded Lady’s face didn’t know I was there at all.

“Young Lassie,” said the Blinded Lady. “What is the color of your Derry’s eyes?”

“Why–why–black!” said Rosalee.

“U-m-mmm,” said the Blinded Lady. “Black?” She began to munch a peppermint. “U-m-m-m,” she said. She jerked her head. Her nose looked pretty sharp. “That’s right, Young Lassie!” she cried. “Love _early_! Never mind what the old folks say! Sometimes there isn’t any late! Love all you can! Love—-!” She stopped suddenly. She sank back in her skirts again. And rocked! Her nose didn’t look sharp any more. Her voice was all whispers. “Lassie,” she whispered, “when you choose your Peacock Feather Fan–choose the one on the top shelf! It’s the best one! It’s sandal wood! It’s—-”

My boots made a creak.

The Blinded Lady gave an awful jump!

“There’s someone else in this room besides the Young Lassie!” she cried.

I was frightened. I told a lie.

“You’re en–tirely mistaken!” I said. I perked Rosalee’s hand. We ran for our lives. We ran as fast as we could. It was pretty fast!

When we got out to the Road our Father and Mother were waiting for us. They looked pleasant. We liked their looks very much.

Carol was waiting too. He had his eyes shut. His mouth looked very surprised.

“Carol’s trying to figure out how it would feel to be blind,” said my Mother.

“Oh!” said Rosalee.

“O–h!” said I.

Carol clapped his hands.

Rosalee clapped her hands.

I clapped my hands.

It was wonderful! We all thought of it at the same moment! We shut our eyes perfectly tight and played we were blinded all the way home!

Our Father and Mother had to lead us. It was pretty bumpy! 9L0-623 Braindump I peeped some! Rosalee walked with her hands stretched way out in front of her as though she was reaching for something. She looked like a picture. It was like a picture of something very gentle and wishful that she looked like. It made me feel queer. Carol walked with his nose all puckered up as though he was afraid something smelly was going to hit him. It didn’t make me feel queer at all. It made me laugh.

“No’m!” I promised.

“Put all the Beauty you can _inside_ your head!” said the Blinded Lady.

“Yes’m!” I promised. “And I’ve just thought of another one that I know! It’s about

You must wake and call me early, call me early, mother dear, For I’m to be Queen o’ the May, mother, I’m to be—-”

“_Foolish!_” said the Blinded Lady. “It wasn’t sounds I was thinking of this time, but _sights_!” She pushed me away. She sighed and sighed. It puffed her all out. “O–h,” 9L0-062 Exam she sighed. “O–h! Three pairs of Young Eyes and all the World waiting to be looked at!”

She rocked her chair. She rocked it very slowly. It was like a little pain.

“I never saw _anything_ after I was seventeen!” she said. “And God himself knows that I hadn’t seen anywheres near enough before that! Just the little grass road to the village now and then on a Saturday afternoon to buy the rice and the meat and the matches and the soap! Just the wood-lot beyond the hill-side where the Arbutus always blossomed so early! Just old Neighbor Nora’s new patch-work quilt!–Just a young man’s face that looked in once at the window to ask where the trout brook was! But even these pictures,” said the Blinded Lady, “They’re fading! Fading! Sometimes I can’t remember at all whether old Nora’s quilt was patterned in diamond shapes or squares. Sometimes I’m not so powerful sure whether the young man’s eye were blue or brown! After all, it’s more’n fifty years ago. 9L0-062 It’s new pictures that I need now,” she said. “New pictures!”

She took a peppermint from a box. She didn’t pass ‘em. She rocked her chair. And rocked. And rocked. She smiled a little. It wasn’t a real smile. It was just a smile to save her dress. It was just a little gutter to catch her tears.

“Oh dear me–Oh dear me–Oh dear me!” said my Mother.

“Stop your babbling!” said the Blinded Lady. She sniffed. And sniffed. “But I’ll tell you what I’ll do,” she said. “These children can come back here next Saturday afternoon and—-.”

“Why there’s no reason in the world,” said my Mother, “why they shouldn’t come every day!”

The Blinded Lady stopped rocking. She almost screamed.

“Every day?” she said. “Mercy no! Their feet are muddy! And besides it’s tiresome! But they can come next Saturday I tell you! And I’ll give you a prize! Yes, I’ll give two prizes– 9L0-623 for the two best new pictures that they bring me to think about! And the first prize shall be a Peacock Feather Fan!” said the Blinded Lady. “And the second prize shall be a Choice of Cats!”

“A Choice of Cats?” gasped my Father.

The Blinded Lady thumped her cane. She thumped it pretty hard. It made you glad your toes weren’t under it.

“Now mind you, Children!” she said.

“It’s got to be a _new_ picture! It’s got to be something you’ve seen yourself! The most _beautifulest_! The most _darlingest_ thing that you’ve ever seen! Go out in the field I say! Go out in the woods! Go up on the mountain top! And _look around_! Nobody I tell you can ever make another person see anything that he hasn’t seen himself! Now be gone!” said the Blinded Lady. “I’m all tuckered out!”

“Always,” said my Mother. “But never deaf!”

“Oh _Tush_!” said the Blinded Lady. “Don’t be stuffy! Afflictions were meant to talk about!”

“But Carol, you see,” said my Mother, “can’t talk about his! So _we_ don’t!”

“Oh–_Tush_!” said the Blinded Lady.

She pushed Carol away. She thumped her cane on the braided rug.

“There’s one here, isn’t there,” she said, “that 9L0-008 Braindump hasn’t got anything to be sensitive about? Let the Young Lassie come forward,” she said, “so I can touch her face!”

It made Rosalee very pink to have her face explored.

The Blinded Lady laughed as she explored it.

“Ha!” she said. “Age about seventeen? Gold hair? Sky-blue eyes? 9L0-062 Complexion like peaches and cream?–Not much cause here,” laughed the Blinded Lady, “for this Young Lassie ever to worry when she looks in the glass!”

“Oh but she does!” I cried. “She worries herself most to death every time she looks!–She’s afraid her hair will turn gray before Derry comes!”

“S-s-h!” said everybody.

The Blinded Lady cocked her head. She ruffled herself. It looked like feathers.

“Derry?” said the Blinded Lady. “Who’s Derry?–A _beau_?”

My Father gruffed his throat.

“Oh Derry’s just a young friend of ours,” he said.

“He lives in Cuba,” said my Mother.

“Cuba’s an island!” I said. “It floats in water! They eat bananas! They have fights! It’s very hot! There’s lots of moonlight! Derry’s father says that when Rosalee’s married he’ll build a—-.”

“Hush, Ruthy!” said my Father. “You’ve talked quite enough already!”

The Blinded Lady patted her skirts. They billowed all around her like black silk waves. It looked funny.

“H-m-m-mmm!” she said. “Let the Child-Who’s-Talked-Too-Much-Already come forward now so that I can feel her face!”

I went forward just as fast as I could.

The Blinded Lady touched my forehead.

She smoothed my nose,–my cheeks,–my chin.

“U-m-mmm,” she said. “And ‘Ruthy’ you say is what you call her?”

My Father twinkled his eyes.

“We have to call her something!” he said politely.

“And is this bump on the forehead a natural one?” said the Blinded Lady. “Or an accidental one?”

“Both!” said my Father. “That is, it’s pre-em-i-nently natural for our daughter Ruthy to have an accidental bump on her forehead.”

“And there are, I infer,” said the Blinded Lady, “one or two freckles on either side of the nose?”

“Your estimate,” said my Father, “is conservative.”

“And the hair?” said the Blinded Lady. “It hasn’t exactly the texture of gold.”

“‘Penny-colored’ we call it!” said my Mother.

“And not exactly a _new_ penny at that, is it?” said the Blinded Lady.

“N–o,” said my Mother. “But rather jolly 9L0-062 Dump all the same like a penny that’s just bought two sticks of candy instead of one!”

“And the nose turns up a little?” said the Blinded Lady.

“Well maybe just a–trifle,” admitted my Mother.

The Blinded Lady stroked my face all over again. “U-m-m-m,” she said. “Well at least it’s something to be thankful for that everything is perfectly normal!” She put her hands on my shoulders. She shook me a little. “Never, _never_, Ruthie,” she said, “be so foolish as to complain because you’re not pretty!”

The Blinded Lady

The Blinded Lady lived in a little white cottage by the Mill Dam.

She had twenty-seven cats! And a braided rug! 9L0-008 And a Chinese cabinet all full of peacock-feather fans!

Our Father and Mother took us to see them.

It smelt furry.

Carol wore his blue suit. Rosalee wore an almost grown-up dress. I wore my new middy blouse.

We looked nice.

The Blinded Lady looked nice too.

She sat in a very little chair in the middle of a very large room. Her skirts were silk and very fat. They fluffed all around her like a pen-wiper. She had on a white lace cap. There were violets in the cap. Her eyes didn’t look blinded.

We sat on the edge of our chairs. And stared at her. And stared. She didn’t mind.

All the cats came and purred their sides against our 9L0-008 Dump legs. It felt soft and sort of bubbly.

The Blinded Lady recited poetry to us. She recited “Gray’s Elegy in a Country Churchyard.” She recited “The Charge of the Light Brigade.” She recited “Bingen on the Rhine.”

When she got all through reciting poetry she asked us if we knew any.

We did.

We knew “Onward Christian Soldiers,” and “Hey Diddle, Diddle, the Cat and the Fiddle.” And Rosalee knew two verses about

It was many and many a year ago
In a kingdom by the sea,
That a maiden lived whom you may know
By the name of Annabel Lee.

We hoped the Blinded Lady would be pleased.

She wasn’t!

The Blinded Lady said it wasn’t nearly enough just to know the first two verses of anything! That you ought to know all the verses of everything! The Blinded Lady said that every baby just as soon as it was born ought to learn every poem that it possibly could so that if it ever grew up and was blinded it would have something to amuse itself with!

We promised we would!

We asked the Blinded Lady what made her blinded.

She said it was because she made all her father’s shirts when she was six years old!

We promised we wouldn’t!

“And now,” said the Blinded Lady, “I’d like to have the Little Dumb Boy come forward and stand at my knee so I can touch his face!”

Carol didn’t exactly like to be called the Little Dumb Boy,
9L0-008 Exam but he came forward very politely and stood at the Blinded Lady’s knee. The Blinded Lady ran her fingers all up and down his face. It tickled his nose. He looked puckered.

“It’s a pleasant face!” said the Blinded Lady.

“We like it!” said my Father.

“Oh _very_ much!” said my Mother.

“Has he always been dumb?” said the Blinded Lady.

native memory management algorithms. You must configure the guest operating system with sufficient swap space.
o Swap Files - hosts use swapping to forcibly reclaim memory from a virtual machine when the vmmemctl driver is not available or is not
responsive. You must reserve swap space for any unreserved virtual machine memory (the difference between the reservation and the
configured memory size) on per-virtual machine swap files.
o If you are overcommitting memory, to support the intra-guest swapping induced by ballooning, ensure that your guest operating systems also
have sufficient swap space. This guest-level swap space must be greater than or equal to the difference between the virtual machine’s
configured memory size and its Reservation.
o Many workloads present opportunities for sharing memory across virtual machines.
o To determine the effectiveness of memory sharing use resxtop or esxtop to observe the actual savings. The PSHARE field of the interactive
mode in the Memory page. 220 702
o You measure guest physical memory using the Memory Granted metric (for a virtual machine) or Memory Shared (for an ESX/ESXi host). To
measure machine memory, however, use Memory Consumed (for a virtual machine) or Memory Shared Common (for an ESX/ESXi host).
o The VMkernel maps guest physical memory to machine memory.
o Multiple regions of guest physical memory might be mapped to the same region of machine memory (in the case of memory sharing) or
specific regions of guest physical memory might not be mapped to machine memory (when the VMkernel swaps out or balloons guest physical
memory)
o Resource Pool Hierarchy can have Parents, Children, and Siblings.
o Resource Pool Admission Control - Before you power on a virtual machine or create a resource pool, check the CPU Unreserved and Memory
Unreserved fields in the resource pool’s Resource Allocation tab to determine whether sufficient resources are available.
o A group power on will power on multiple virtual machines at the same time.
o VMotion does not support raw disks or migration of applications clustered using Microsoft Cluster Service (MSCS).
o Other VMware products or features, such as VMware vApp and VMware Fault Tolerance, might override the automation levels of virtual
machines in a DRS cluster.
o An affinity rule specifies that two or more virtual machines be placed on the same host. An anti-affinity DRS rule is limited to two virtual
machines,
o If two rules conflict, the older one will take precedence, and the newer rule is disabled.
o Disabled rules are ignored. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of affinity rules.
o When a host machine is placed in standby mode, it is powered off.
o Hosts are placed in standby mode by the VMware DPM feature
o A cluster becomes overcommitted (yellow) when the cluster does not have the capacity to support all resources reserved by the child resource
pools. Typically this happens when cluster capacity is suddenly reduced.
o A cluster enabled for DRS becomes invalid (red) when the tree is no longer internally consistent, that is, resource constraints are not observed.
o VMware DPM can use one of three power management protocols
o IPMI - Intelligent Platform Management Interface
o iLO - Hewlett-Packard Integrated Lights-Out
o WOL - Wake-On-LAN 220 701
o If a host supports multiple protocols, they are used in the following order: IPMI, iLO, WOL.
o The VMotion NIC on each host must support WOL to use that protocol.
o The DRS threshold and the VMware DPM threshold are essentially independent. You can differentiate the aggressiveness of the migration and
host-power-state recommendations.
o Verify that DPM is functioning properly by viewing each host’s Last Time Exited Standby information.
o The most serious potential error you face when using VMware DPM is the failure of a host to exit standby mode when its capacity is needed
by the DRS cluster. Use the preconfigured Exit Standby Error alarm for this error.
o DRS Recommendations have 5 levels (1-5). Priority 1, the highest, indicates a mandatory move because of a host entering maintenance or
standby mode or DRS rule violations. Other priority ratings denote how much the recommendation would improve the cluster’s performance;
o Prior to ESX/ESXi 4.0, recommendations received a star rating (1 to 5 stars) instead of a priority level.
o Non-Uniform Memory Access (NUMA) systems are advanced server platforms with more than one system bus.
o Some virtual machines are not managed by the ESX/ESXi NUMA scheduler: if you manually set the processor affinity for a virtual machine, or
virtual machines that have more virtual processors than the number of physical processor cores available on a single hardware node.
o When a virtual machine is powered on, ESX/ESXi assigns it a home node. This is initially assigned to home nodes in a round robin fashion.

o Perform a rescan each time you make one of the following changes:
o Create new LUNs on a SAN.
o Change the path masking on a host.
o Reconnect a cable. 640 802 Dumps
o Make a change to a host in a cluster.
o Change CHAP settings or add new discovery addresses.
o If you notice unsatisfactory performance for your software iSCSI LUNs, you can change their maximum queue depth by using the vicfgmodule
command.
o The iscsi_max_lun_queue parameter is used to set the maximum outstanding commands, or queue depth, for each LUN accessed through the
software iSCSI adapter. The default is 32, and the valid range is 1 to 255.
o Setting the queue depth higher than the default can decrease the total number of LUNs supported.
Appendix A - iSCSI SAN Configuration Checklist
o Set the following Advanced Settings for the ESX/ESXi host:
o Set Disk.UseLunReset to 1
o Set Disk.UseDeviceReset to 0
Appendix B - VMware vSphere Command-Line Interface
o The resxtop command provides a detailed look at ESX/ESXi resource use in real time.
o The vicfg-iscsi command allows you to configure software or hardware iSCSI on ESX/ESXi hosts, set up CHAP parameters, and set up
iSCSI networking.
o Use the vicfg-mpath command to view information about storage devices, paths, and multipathing plugins.
o Use the esxcli corestorage claimrule command to manage claim rules. Claim rules determine which multipathing module should
claim paths to a particular device and manage the device.
o The vmkping command allows you to verify the VMkernel networking configuration.
Appendix C - Managing Storage Paths and Multipathing Plugins (Same as Appendix B in the Fibre Channel SAN Configuration Guide)
Resource Management Guide
o The need for resource management arises from the over-commitment of resources.
o Resources include CPU, memory, power, storage, and network resources.
o The guide focuses primarily on CPU and memory. Power resource consumption can also be reduced with the Distributed Power Management
(DPM) feature. 640-802</a
o ESX/ESXi manages network bandwidth and disk resources on a per-host basis, using network traffic shaping and a proportional share
mechanism, respectively.
o Shares specify the relative priority or importance of a virtual machine (or resource pool).
o Shares are typically specified as High, Normal, or Low and these values specify share values with a 4:2:1 ratio. (or can set Custom value)
o A reservation specifies the guaranteed minimum allocation for a virtual machine.
o The reservation is expressed in concrete units (megahertz or megabytes).
o Reservation defaults to 0.
o Limit specifies an upper bound for CPU or memory resources that can be allocated to a virtual machine. It never gets more than this.
o A limit is expressed in concrete units (megahertz or megabytes).
o CPU and memory limit default is unlimited.
o Using limits can be beneficial if you want to manage user expectations, but might waste idle resources.
o Expandable Reservation defines whether reservations are considered during admission control.
o Overhead Reservation is the amount of the “Reserved Capacity” field that is being reserved for virtualization overhead.
o Worst Case Allocation is the amount of (CPU or memory) resource that is allocated to the virtual machine based on user-configured resource
allocation policies (for example, reservation, shares and limit), and with the assumption that all virtual machines in the cluster consume their
full amount of allocated resources.
o Admission Control - If enough unreserved CPU and memory are available, or if there is no reservation, the virtual machine is powered on.
Otherwise, an Insufficient Resources warning appears.
o ESX/ESXi cannot enable hyperthreading on a system with more than 32 physical cores, because ESX/ESXi has a logical limit of 64 CPUs.
o Hyperthreaded Core Sharing Modes: 640 802 braindumps
o Any - can freely share cores with other virtual CPUs.
o None - each virtual CPU should always get a whole core to itself, with the other logical CPU on that core being placed into the halted
state.
o Internal - cannot share cores with vCPUs from other virtual machines. Can share cores with the other virtual CPUs from the same virtual
machine. Only for SMP virtual machines.
o For the best performance, when you use manual affinity settings, include at least one additional physical CPU in the affinity setting to allow at
least one of the virtual machine’s threads to be scheduled at the same time as its virtual CPUs.
o Dynamic Voltage and Frequency Scaling (DVFS) - You can configure your hosts to dynamically switch CPU frequencies based on workload
demands.
