Issue of booking Resource Pool

• Issue of Resource Pools

  I'm relatively new to the VMware Infrastructure. I read a lot of documentation available, but I'm having a hard time getting my head around Resource Pools. I was wondering if someone could point me to documentation that includes examples of how and why the Resource Pools are used in a real production environment. In the meantime, if anyone could answer the following questions, I would appreciate it:

  It seems to me that the RPs have been created to distribute resources according to how many resources needs of an organizational unit. For example if a unit is in need of 5 machines running at 2 mhz each with 2 GB of ram, then a suitable unexapandable PR for this unit would include 10 mhz and 10 gigabytes of ram and if any machine would be created which depleted resources, the machine would not be able to start. Is this correct? If so, then how the RP can manage how much mhz CPU using each machine? If all 5 machines were launched at the same time, would not be the limit of 10 mhz be quickly exhausted? The machine would be stopped / stop? Or would the machine just run with > less < mhz?

  RPs affect DRS or HA? How can he? Because the DRS moves a machine so she uses a fixed amount of resources on a machine, ESX, how RPs come into play if they are universal to the cluster?

  Thank you very much

  psynophile,

  Relevant issues. RPs are used "Undernet world", Yes, but I've not seen too real implementations using it. But everything I've seen, they work very well for purposes of limitation and booking. Answer your questions:

  "any machine would be created which depleted resources, the machine would not be able to start": it depends. The limitation will be strong for the RAM (the sixth VM fuel not on), but for CPU the ESX will try to share the 10 GHz (I guess than the typo in the MHz) with all the virtual machines on the RP - always count you can provide each machine with a reserve of CPU, so if the reservation is greater than the limit , then you may not be able to power on the nth VM.

  If so, then how the RP can manage how much mhz CPU using each machine? If all 5 machines were launched at the same time, would not be the limit of 10 mhz be quickly exhausted? : it depends on the use of each virtual computer processor. The performance will be degraded IF the limit of 10 GHz is not sufficient to them.if you 5 database within this RP servers, they will probably present a performance degradation. But will never halt/stop.

  RPs affect DRS or HA? : as the RPs are on a group level, they do not. DRS will change virtual machines one ESX to another depending on the host CPU/RAM usage. HA won't be affected, only that your reservations can reduce the amount of servers for failover, you have set up for it.

• Configuration issue Resource Pool

  We do currently not pools of resources within our environment. What we seek to do is implement with reserves resource pools memory based on our VM sizes. For example, we will create a pool of resources of 4 GB for virtual machines with 4 GB of memory, a pool of resources for virtual machines with 8 GB of memory, 8 GB etc. We would then define the reserve of memory halfway (the virtual machine) for each pool. Thus, the 4 GB VM will have a reserve of 2GB. Our goal in doing this is to reduce the size of our swap files. We have a few virtual machines spread in our environment that are configured independently. For example, a 12 GB VM with a reserve of 6 GB has a 6 GB swap file. At the global level, it could save us a lot of space to store data.

  A few questions while doing this, however. What will happen for the VMs who have already activated bookings? The resource pool overrides the individual VM settings?

  And no one sees this as having harmful effects on an HA event? We had problems in the past in a different environment with reservations (big 38 GB +), and when we lost a multitude of virtual machines have been unable to turn on because there was no more available resources.

  Resource pool reservations have no effect on the reservation of the virtual machine in the pool - they are independent

  Difficulties with HA is a question - another is by assigning reservations to all VM you can come to the point where an ESXi host won't have enough memory to satisfy the reserve causing the VM does not start.

• Understand how resource pools really work

  In the research on how to properly nail using the resources for the resource pools in our groups, I found that there are nuances that are not specifically documented about 'Booking' vs 'Limit' that relate to Resource Pools. If someone is an expert Resource Pool please chime. I am specifically looking for validation of what we believe is true.

  Here's the deal:

  So based on my interpretation of the response and our conception of resource pools, it looks like the 'limit' is always an important value that decided the full amount of the memory of the virtual computer (reserved memory + swapped memory shared memory + virtual memory) in a pool of resources to all virtual machines and does not imply that memory is drawn from a pool of resources of the parent.

  In our environment, we allow 'extensible booking '. Our question was, 'the value limit of importance. " We assumed that with the 'extensible' NOT VERIFIED that the value reserve limit didn't matter, even if it is not grayed out. So if the limit is not grayed out, it allows resources to be charged to the parent? I understand that this is not the case. In our case, the limit does not mean that the resources drawn from the parent, but seems rather this sets the cap of the memory of all virtual machines in the pool resource can use (reserved memory, expanded memory, shared memory + virtual memory).

  Example (1): we have a pool of resources called "Exchange-RP' 10 GB reserved, not expandable, and a limit of 20 GB. If we have 11 VMs each configured with 2 GB of ram (individual virtual machines have no reservation but the virtual machine is configured to 2 GB).

  We can power on the first 10 virtual machines (10 x 2 = 20 GB) but the 11 will not because it exceeds the limit.

  In this example how the 10VMs become the 2 GB? I guess everyone gets 1 GB of physical memory and consists of 1 GB of virtual memory (swap, shared, etc., not physical ram). At no time is issued physical memory of the mother.

  Example (2): given the exact scenario above. If the unlimited checkbox is enabled (limit is grey = unlimited), it would mean that the VM 11 would now be allowed to be turned on and booking of physical memory it is just must be shared by all the virtual machines in the pool. It seems that once that we receive too many virtual machines powered that there is too little physical ram per virtual computer and we will begin to see the excessive ballooning and swapping then in turn affect performance.

  Please confirm the above examples is accurate of how memory is managed.

  We are looking to validate that the RP limit value is always important as a strict limit of all memory used by the VMs, not only physical (reserved memory). None of the VMware documents speak to this.

  Thank you

  Welcome to the Forums - example 1: I understand, it's the list resources should act as a host that you oversommit the memory assigned to the list of resources - so you should be able to on this 11th VM - with 11 VM all who are in need of 2 GB and with the limit set at 20 GB - if all VMs using their 2 GB and no page sharing occurring I expect to see ballooning by VM vmkernel swap files - now used if you have 2 GB reservations you would be able to turn on 5 VMs in this example because with 5 virtual machines would use you all 10 GB of memory reserved - value and the vmkernel will not power on a virtual machine if it cannot guarantee its reserve-

  Example 2 - see above - even with alimit together, you will be able to oversommit the memory in the RP - the only thing you will earn if you have the limit set to unlimited is that you be Basel to put multiple virtual machines and impact on all users on the ESx host or cluster -

• Monitor the IOPS / s in a Resource Pool?

  Hello world

  I am quite new to vROM and just get your feet wet for me.  I've been delving into the book "Mastering Operations Manager vRealize" useful and which was helpful, but I'm trying to understand an important piece on:

  We have pools of different resources for different departments within our Organization, and I try to get a good graph for IOPS / s in each resource pool.  I was able to get a list of all virtual machines in a resource pool by creating a dashboard with the widget resource pool game object selector, then use "Diagnose e/s disk of the Virtual Machine list" view to see all the virtual machines within the list of resources and then for the summary allows you to SUM add them all together.  This gives me a number, but does nothing for this over time.  I'd like to be able to see that number over the next few months (even if it means just go ahead of data today onward, not historical).

  Any ideas?  I think I must be missing something, like the Resource Pool looks like it would be a good way to measure the impact of the drive.  Folder of the Virtual Machine might work also, but is not as clean as I would like.

  Hello world

  Right after I got this resolved so I thought I would mention it here in case anyone else is curious.  It has to do with the SuperMetrics.

  The formula I created is as follows:

  SUM (${adapterkind = VMWARE, resourcekind = VirtualMachine, attribute is virtualDisk | commandsAveraged_average, depth = 1})

  It takes the sum of all virtual machines to a level under the resource pool.  I also used average and Max values, because this helps to show trends and you have aberrant VMs eating a ton of IOPS / s.

  I received lots of help from Iwan Rahabok virtual red point.  Specifically, this thread here: http://virtual-red-dot.info/any-vm-abusing-your-iaas-by-doing-excessive-workload/

• Root user cannot create VMS within the Resource Pool after you rename the Cluster

  Currently, vCenter manages two clusters. I renamed a single cluster and the root user seems now are not allowed to create a new Virtual Machine in resource pools to the title of the group with the changed name. I tried to change the name of the cluster to its original name... no luck.

  The root user can still create a VM under the individual cluster nodes, but not in a resource pool.

  The cluster that has not been renamed yet can be managed completely with the root user. Resource pools it allow me to create a virtual machine.

  I found this last issue and checked on each cluster node that the ACEDataRoleId is-1 for each section: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1031192

  I am at a loss, any help would be greatly appreciated! Thank you!

  I think it's a bug. When I created a new data center and migrate all nodes in cluster about him, the permissions problem I was experiencing did not follow.

  Thank you for your help.

• Summary of the Resource Pool tab

  It is what I read from the book of ICM5:-

  Orders (not shown) component allows you to perform actions such as creating a virtual machine, creating a pool of resources and changing the parameters of a pool of resources.
  I did not understand this line. Can someone help me explain this threshold.

  In the vSphere Client, select a resource pool in the left pane. Now, select the Summary tab for the pool of resource selected in the right pane. There is a component of commands (or box) visible in the bottom left of this tab with the following options: Edit virtual machine settings, new Pool of resources.

• DRS rules and Resource Pools

  Is it possible to assign the DRS rules to Resource Pools instead of creating groups of DRS and adding to the DRS group VMs and then creating a rule
  I ask this question because of a problem that I currently have
  I am far from being an expert as you'll see soon and back to the use of support groups
  If it I'll give you my scenario
  I have 4 ESX host in my test group
  2 hosts are connected to zFCP
  And all 4 are connected to independent contractors
  I have a resorce pool call FC and another called ISCSI
  We constantly evolve around VM between these 2 pools
  The highest availability VM remains on the rest on ISCSI FC
  I would like to create a rule that States if a virtual machine is in the RP FC then he must reside on host A and B, and if it resides on ISCSI it can reside on any host
  I realize that there is still other issues involved here as data themselves warehouses
  but it is another matter that he owns the rights
  We migrate VMs and the data store when we leave the virtual machine to another RP 1
  If the rule would be always true
  I would like to hear from you
  on this topic
  for now I just use rules and groups of DRS
  Thank you

  I don't think this is possible from the point of view of rule affinity DRS, as he has no relationship with resources or VM disk pools. This seems to be a single-use resource pools.

  You could probably do with a set of scripts PowerCLI who would check two resource pools and ensure that the virtual machines to the breast have their records on the correct data store and if not do a svMotion.

• Move a guest to the different resource pool

  I have a box of ESXi 4.1 stand alone. Like a fool when it was created, I don't create pools of resources. Now that more added, I started using pools of resources. I tried to find info on the passage of the guests to a pool different and found that it could be issues (kb/1018360) but cannot find how to actually move a guest. Any ideas?

  You can only select and drag the virtual computer to the new resource pool

• Script to check the correct resource pools

  Hi guys

  Hoping someone can help with PowerCLI issue?

  I want to set up a script PowerCLI who together share CPU and memory allocated to all VMS in each Resource Pool, add them together and compare them with resource information in the list of resources and those who differ from a CSV output (including how on every property is different).

  The idea is that this script will quickly check through our vast domain for incorrectly configured in the resource pools (ie. those who have not been updated).

  Anyone able to help give advice on how I can get that data into PowerCLI from the pool of resources and the virtual computer?

  Thank you very much

  I don't know if the values you provide are correct for what is planned.

  Especially the MaxCpuUsage won't say much because this will normally reflect the total amount of CPU resources on the host (provided that the customer has no defined limits).

  The following should give a better picture (I guess)

  $dcName = 
  $report = @()
  $dc = Get-View -ViewType Datacenter -Filter @{"Name"=$dcName}
  Get-View -ViewType ResourcePool -SearchRoot $dc.MoRef | where{$_.Name -ne "Resources"} | %{
       $rp = $_
       $rpMem = 0
       $rpCpu = 0
       Get-View -ViewType VirtualMachine -SearchRoot $rp.MoRef | %{
            $rpMem += $_.Summary.QuickStats.hostMemoryUsage
            $rpCpu += $_.Summary.QuickStats.overallCpuUsage
       }
       $report += New-Object PSObject -Property @{
            Name = $rp.Name
            "VmCpuTotal (MHz)" = $rpCpu
            "VmMemTotal (MB)" = $rpMem
            RpCpu = $rp.Runtime.Cpu.UnreservedForVm
            RpMem = $rp.Runtime.Memory.UnreservedForVm / 1MB
       }
  }
  $report | Export-Csv "C:\ResPool.csv" -NoTypeInformation -UseCulture
  

  Note that this does not overcommitment account. To have the script must use the unreservedForPool rather than the UnreservedForVm property property.

• Resource pools &amp; reservations?

  Hello

  My question pools of resources. I'll cut right to hunt.

  If a resource pool is created and a reserve of memory is set to say that this means-4069 MB each VM on the host is allocated physical memory 4 GB when it starts?

  When its given a reserve of say 4 GB it never will give the host it's memory if it is not needed?

  What happens if a guest is only given 2 GB of memory, but the reserve is set to 4 GB. It will only take 2GB or take all 4 GB host?

  Here is my scenario:

  An ESX host is given to 8 GB memory.

  4 VMs were created and given 2 GB of memory each.

  A Resource Pool is created and a reserve memory is set to 4 GB of memory.

  This VM average only 2 can be powered on at the same time? Or all 4 machines can be powered on?

  I wonder because someone went and created a bunch of pools of resources like this to my work. I'm new to the technology, but it seems as if they were incorrect installation. My guess is that they were created after the virtual machine has been powered...

  If a resource pool is created and a reserve of memory is set to say that this means-4069 MB each VM on the host is allocated physical memory 4 GB when it starts?

  N ° this means that the POOL reserves 4 GB to apply to these virtual machines.  ALL VM sharing the resource in a POOL.  Up to 4 GB is shared between the virtual machine in this pool.

  When its given a reserve of say 4 GB it never will give the host it's memory if it is not needed?

  NOPE.  Not once it is used, it is reserved.  If you want to share, just use stock instead of reservations for the swimming POOL.  Increase the priority and this POOL will have a higher priority.

  What happens if a guest is only given 2 GB of memory, but the reserve is set to 4 GB. It will only take 2GB or take all 4 GB host?

  YES.  Once reservations are applied, they don't get until they are not necessary.  Once a virtual computer in that pool gets hold of the memory, he won't give it back unless it is turned off.  But since you apply the reserve to a POOL it is immediate, so if your cluster has 32GB of memory, this POOL booked 4GB, leaving 28 GB to share the rest of the cluster, but only this POOL keeps at least 4 GB of memory to ensure that enough memory is given to its members.  This will be guaranteed to members of this POOL of memory.

  This VM average only 2 can be powered on at the same time? Or all 4 machines can be powered on?

  Well what is happening, is that the booking of the pool takes these and its guarnateed to get memory.  Other virtual machines are going to starve (if not left) until this pool is granted to ALL memory.  Once the pool is enough resource, reset of struggle of pools/VM without reservation on the remaining memory.

  Until you are absolutely certain that your VM do NOT get what they need, I would turn off reservations.  They should be used with caution if you don't know what you're doing, you can really tilt performance and cause problems.  So change the settings of the shared pool, back not book memory and monitor the performance of the virtual machine.  If there seems to be some conflict later, you can always reactivate.

• The list of all the Resource Pools that are part of a group of ESXi

  Hello

  I'm trying to get a piece of code work that will list all the resource pools that are present in a cluster of ESXi.

  • I know I can find what list of resources of a virtual machine resides in.  I don't want that.

  // Find a matching resource pool on an ESXi hosts
    var esxiCluster = esxiHost.parent;
    var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  
  
    System.log("what is the ESXi cluster: " + esxiCluster.name);
    System.log("vimtype: " + esxiCluster.vimType);
    System.log("what pools exists: " + esxiClusterResourcePools);
  

  So I know that the vimType will come back with what I expect (ClusterComputeResource).  The question I have is the object "resourcePool" is reference to the root resource list (in my case, it is 'resources').

  What I want is all DRS resource pools are configured.  I need something like "resourcePool_ResourcePool.children".

  Any help is appreciated.

  Thank you

  Hello

  Check if this code example that works in your case:

  var esxiCluster = esxiHost.parent;
  var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  var pools = System.getModule("com.vmware.library.vc.resourcePool").getAllChildResourcePool(esxiClusterResourcePools);
  
  // dump names of child pools
  for each (var pool in pools) {
    System.log(pool.name);
  }
  

• Resource pool limit Datastore Quota

  Hello

  I need to limit the quota of data store for a specific group, e.g. they can only allocate 1 TB to 10 TB data store for their virtual machines.

  CPU and RAM are possible with resource pools, but how can I accomplish this with data warehouses?

  what you are asking for can be easily achieved in vRealize Automation or vCloud Director.

  But in the vSphere environment, you have to achieve by using roles and permissions, where you create datastore with limited storage space and assign permission to users wished to not to exceed the use of storage space after certain limit. That way they won't see all data warehouses and they will not be able to use all the space.

• Resource pools

  We have 3 guests in a cluster, 2 x 16 hearts @ 2 200 mhz and 1 x 20 hearts @ 2 300 MHz, which gives us a total of 116 400 MHz. The maximum limit that I can refer to a resource pool is 103 000 MHz, where would lose us the other 13 400 MHz?

  It is the hypervisor above, which is basically the amount reserved for the hypervisor processes run safely.

  It is editable. There is a nice article where Tom Fojta talking.

• Reservation of CPU Resource Pool

  Hello everyone

  I need feedback on pools of resources, and in particular for the CPU share uses.

  I read the "Mastering Vmware vSphere 5.5" and I understand how Vmware works for the share of the CPU.

  I have the a customer who want to buy me a resource pools for this virtual machine management. He will buy vCPU 26 and 64 GB of RAM.

  I know how to set up the RAM, but I did not how to do for the CPU.

  I started by 26 multiples by the clock of the CPU, but the value is higher or lower than 1 ESXi. So I think I made a mistack.

  Can someone help me to understand how do for the CPU resource pool.

  Thanks in advance for your help.

  Best regards

  Matt

  Hi Matt,

  Personally, I put a limit of 2 GHz by heart. CPU host have 3.0 GHz. On this way a big vm as you can 'kill' the host and other virtual machines on it.

  When you use the same limit, you will need to set the limit at 52000 MHz (26 x 2000 MHz Cores).

  Kind regards
