Use of the Resource Pool with vSphere Essentials

• 'Custom actions' of the CPU in the Resource Pools: should I also set the VMs child on "custom"?

  Hello world

  Imagine a VMware vSphere 4.1 cluster managed, of course, by vCenter Server, with some 4.1 ESXi hosts.

  This cluster has 3 Pools of resources: development, Production, quality

  Now consider that the Resource Pools have been initially implemented in the following way, about the 'actions' for 'CPU resources':

  -Development: Shared low =

  -Quality: Sharing = Medium

  -Production: Sharing high =

  Several virtual machines were placed in the Resource Pools. Some virtual machines are single vCPU, but others are vSMP ones: some have 2 vCPU and some of them have 4 vCPU.

  Now, I read the following articles of the (large) put at disposal by Duncan Epping, VMware, in his blog "Yellow brick", on "Resource Pools" and actions:

  The Resource Pool priority-Pie Paradox - yellow bricks [written by Craig Risinger]
  http://www.yellow-bricks.com/2010/02/22/the-resource-pool-priority-pie-paradox/

  Actions on Resource Pools

  http://www.yellow-bricks.com/2010/12/14/shares-set-on-resource-pools/

  Actions on a Resource Pool, custom scripted

  http://www.yellow-bricks.com/2010/02/24/custom-shares-on-a-resource-pools-scripted/

  Now, imagine that I have manually changed several Pools of resources from low/normal/high "Custom" and gave them the following values:

  -Development: 3000

  -Quality: 6000

  -Production: 9000

  The virtual machines inside each Resource Pool appear to be all set up to 'Actions' = 'Normal '.

  I want to know is this:

  1 - since I changed Resource Pool shares 'Low' / 'Normal' / 'High' to 'Custom', I should / need to change the 'actions' in each individual VM from "Normal" to "Custom"?

  2 - I'm guessing that the sum of the actions of all virtual machines in a Resource Pool must be equal to the actions that I gave to this Pool of resources. Am I wrong?

  3 - I also guess that the only practical way to make this change to Virtual PCs, if necessary, is to generate scripts, preferably using PowerCLI. Friend, I have right?

  Thanks in advance!

  See you soon,.

  Whatever resources the resource pool level are applicable to this pool of resources and will get the part accordingly. So that resources will be divided between the virtual machines according to the shares they hold.

  Example:-two pool of resources A and B.

  Total cycles CPU = 10000 Cycles CPU

  A part (custom set) = 6000 CPU Cycle.

  Part B (custom set) = Cycle CPU 4000.

  Now a resource pool has three virtual machines powered with shares.so high normal and low on this desire to cycles CPU 6000 cases divided among them in 4:2:1

  VM1 have = 4 * 6000/7 = 3428 cycles cpu.

  VM2 will get = 2 * 6000/7 = 1714 cycles cpu.

  Vm3 will get = 1 * 6000/7 = 857 cycles cpu.

  so according to your requirement, you can change your actions at the level of the virtual machine.

  PS:shares come into picture when there is a conflict.

• CloneVM_Task fails on the resource pool when cloning tempalte

  I'm trying to use the CloneVM_Task to clone a template, but it keeps failing because no resource pool.  We have a cluster with no pool DRS/HA or resources configuration, we use the cluster for the VCA mode.

  I have a reference to the host server, but I don't know what is needed for the pool of resources, given that we have not one.

  While

  cloning a virtual machine from a template, the resource pool is a required parameter.

  It specifies the resource pool that this virtual machine should be attached.

  Incase you do not have a resourcePool hierarchy, you must specify the root

  resourcePool 'Resources' as a resourcePool. It's the resourcePool

  managed your ComputeResource object. A ComputeResource always has a root

  ResourcePool associated with him.

• Get use of the resources of all virtual machines in a cluster

  Hello

  I have developed a measure of capacity management report that collects all the use of the resources of the virtual machines in a datacenter. The function that collects it looks like this:

  def hostMemoryConsumed =]

  def memoryConsumed = 0.0f

  def memoryGranted = 0.0f

  VMs. each() {}

  VM->

  try {}

  memoryConsumed += vm.host.memory.consumed.current.average / 1024.0f<----- how="" to="" do="" this="" to="" get="" from="">

  memoryGranted += vm.host.memory.capacity.current.average / 1024.0f

  }

  {} catch (NullPointerException e)

  }

  VMS is a function of type parameter VMS VMW

  The works above for virtual machines in the data center, but I need it to be after cluster. I can find a cluster of virtual machines, but I'm having trouble with referring to specific values for example consumed memory and capacity.

  If I change the type parameter: VMW Cluster how the metric reference would look like (see the try {})?

  I don't think that a query will help me.

  Thanks in advance

  Erik Alm

  If you want to do for a cluster, you can just get the list of virtual machines in a cluster of first and passing in your script.  If you have a function for a VMWCluster you can add a parameter for "vmwCluster" that is underneath and it should give you a table (topologyObjects) that has all the virtual machines in the cluster.

  QS = server.get ("QueryService") / / query Service

  tquery = qs.createStatement("!) (' VMWVirtualMachine where esxServer.parent.name = "+" ' "+ vmwCluster +" "" ") .setQueryTopologyObjects (true);

  topologyObjects = qs.executeStatement (tquery) .getTopologyObjects)

• 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);
  }
  

• Cluster with VSphere Essentials

  When I try to create a cluster with VSphere Essentials (no more) I'm offered HA and DRS (they are not greyed out, they are available). Are these trial versions that will be disabled in the future, or they are now included in Essentials?

  My understanding is that they would be unavailable at all. that is, they would be gray.

• vCenter Server with vSphere Essentials best practices for small business

  I hesitated to post this thread for fear of redundancy, but I wasn't able to find an answer in previous discussions.

  I read the installation documentation for vSphere Essentials vCenter Server installation.

  
  Is it a good idea to install vCenter on my ESXi host as a virtual machine?  I don't understand how the server can be installed as a virtual machine if she must always be on.  What happens when I do the updates of the hypervisor, ESXi (4.0 to 4.1)?  This would not cause the vCenter Server to disconnect?

  Because I have Essentials, I don't have a HA and cannot migrate the server vCenter Server to another host as shown in the installation documentation.

  Thank you

  It should not be a problem - if you manually perform the update using either the esxupdate or vcenter command vihostupdate does not at all in the game - if you use VUM he actually intitiates the vihostupdate order - when restarting the host to be reconnecting to vcenter once it is running.

• Understanding of the resource pools

  I thought I knew pools of resources but realize that my interpretation is wrong and despite reading the documentation and navigation

  messages on this site, I'm still confused and hoping someone can help.

  I thought that:

  1. set up a reserve of 256 MB of Ram on a pool of resources means that each virtual machine has been awarded to a minimum of 256 MB of RAM and that if this

  was not available, then the VM not illuminate.

  2. If the limit has been set to unlimited (or even a limit capped to say 90% of the available RAM) a VM would use more RAM if needed.

  3. the allocation of memory in the definition of a virtual machine in the settings was not relevant because the vm used as much ram has been defined by the resource pool.

  However, I can see my graphics that some virtual machines, while using very little memory, resemble the memory is limited.

  What I mean is that when I look at vcentre: resource - VMS-> guest mem % pool. I see a percentage high and in some cases

  the bar indicator changes from green to yellow. I do not know what threshold is reached - possibly the amount of RAM allocated to the VM in its

  configuration settigs.

  So should I do the following:

  1 build a virtual machine and to allocate as much RAM as I think that the VM needs

  2. set the memory reserve on a pool of resources as being the sum of which has been attributed to each virtual machine

  3 or the reservation to be what I think, that each virtual machine will usually use the value

  4. If done correctly, then vms uses more memory in the limits imposed.

  Is none of this?

  TAM

  1 build a virtual machine and to allocate as much RAM as I think that the VM needs

  Of course, it is better to give more ram and maybe avoid swapping

  2. set the reserve memory on a pool of resources as being the sum of what

  have been allocated to each virtual machine

  Of course, you can, it depends on if you have too many commissioning

  3 or the reservation to be what I think, that each virtual machine will usually use the value

  Resource pools have just two functions restrict or warranty. Constraint is that if you overprovised a virtual computer, you can stop hunger on the other

  VMS. Or guarantee the current host does not have enough resources both by the DRS vmotion virtual machine to another host

  4. If done correctly, then the vms uses more memory limits

  imposed.

  The best solution is to use any custom CLI... for example:

  If I get the virtual machines on each resourcepool in the list above, I'd be unable to distinguish if Tier1 is from the branch of a branch of Department2\Prod or Department1\Dev.

  How can I get that information, that is to say, the 'level 1' resourcepool (ResourcePool-resgroup-296) is in which parent resource group.

  There are 2 things to consider before attack us the script.

  (1) resource pools can be created in 2 different locations, under a Cluster and a standalone host

  (2) in the vSphere environment, there are some hidden files. One of them is the pool of resources of the parent 'resources '.

  You can find this file under each group and each stand-alone host.

  The script uses a function called Get-RpPath, which makes it much easier to recursively down the structure of resource pool

  The script now prints the hidden folder "Resources" as the beginning but this can be replaced by the name of the cluster or standalone host just above.

  The script begins with the collection of all of the 'Resources' folders that are hidden in your vSphere environment and recursively then descends from the quest of sub-resourcepools.

  $indent = 4
  
  function Get-RpPath{
       param($rp, $level)
  
       Write-Host ($rp.Name).PadLeft($level + $rp.Name.Length, "-")
       foreach($child in $rp.ChildConfiguration){
            $nrp = Get-View -Id $child.Entity
            if($nrp.GetType().Name -eq "ResourcePool"){
                 Get-RpPath $nrp ($level + $indent)
            }
       }
  }
  
  $clusters = Get-Cluster
  $hosts = Get-VMHost | where {-not ($_.ParentId -like "Cluster*")}
  
  $RProot = $clusters | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  }
  $RProot += ($hosts | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  })
  
  $RProot | Get-View | % {

• Good candidates for the resource pools?

  Hi, I do not currently use resource pools, but often the impression that I should watch more in him.  We have our four node 5.1 cluster 16 web servers (among others in the virtual computer) that are exactly the same and serve the same function.  I was wondering if those who would be good candidates to be added to a pool of resources, so they can take resources needed?  I tend to approve statically the RAM and CPU on these "just in case", but maybe it's stupid, if there is a better way.  Thank you.

  Also consider that if you have no compelling reason to prioritize resources for all virtual machines on one of the virtual computer, then you really don't have a reason to use the resource to all pools.  In this case, each virtual computer will be given some memory he needs on demand, DRS will balance the load between the hosts if a host is out of balance, and there will be fairness when ESXi pray return of VMs pages when there is a conflict.

• RV with Vsphere Essentials 5.1 more

  My Client will buy 2 servers, and each server has 2 CPUs. And he'll buy vsphere essentials 5.1 pack. but the thing is he'll find a server in one place and the other server is in another remote location. two servers can be connected by using a VPN. There are now the following things. Please explain to me that these things can be done.
  1. He must manage two servers using a single VCenter.
  2. he won't buy any external storage. Instead it will use the internal memory. and he needs to implement storage device to do a cluster between the two servers.
  3. must use VR for replication. (from one server to another) without the help of the SRM. He will use the Group feature (VR) essentials with pack.
  4. he needs 20 virtual machines in a server and the same servers in the other server installation. If a server crashes while it must use the remote server as the production server.
  Thank you. Please update me as soon as possible.

• DRS necessary for Resource Pools? (vSphere 5)

  Hello

  We make the leap of XenServer to VMWare at the minute and watch vSphere Standard as a starting block.

  I am looking to use Pools of resources in order to manage resources - is this correct for resource pools work I need DRS (which isn't available in the package of the company)?

  If so, should I still DRS to reserves, limits and shares for each VM?

  Thank you

  Tim

  Hi Tim,.

  the use of resource within a Cluster HA pools to Drs without DRS you can create pools of resource for single guests only.

  DRS is not necessary for reservations, the limits of virtual machines.

  For more information on the management of the resource, check out this doc:
