ESX 3.5 HA and DRS - fully automated parameters

Similar Questions

• Question of DRS HA and fully automated

  I have a vCenter enabled for HA cluster (tolerates 1 default host) and DRS (fully automatic)

  Most of my VM have 2 or 4 GB of memory. Now, I need to create a virtual machine with 32 GB of memory.

  If the DRS load balances my cluster there will be no host monkey with 32 GB of memory available even if the cluster has more than 32 GB of memory available.

  My question is (without entering the calculation of the size of opening calculation etc.) if the host where the 32 GB VM fails and HA restarts the virtual machine on the remaining hosts, DRS balance the cluster to allow the 32 GB VM to start?

  In vSphere 4.1 and later, HA works with DRS "defragment" hosts so that your large VM can be restarted. It is a kind of best effort of activity and is not guaranteed to work. I'm not aware of what is true in 4.0.

  For more details, I suggest the post of Duncan Epping on the subject, start by "how HA to calculate how many slots is available for each host?

• Fully automated DRS cual're mejor opcion para trabjar con vdi

  Hola todos,

  Tengo una duda sober opcion cual en DRS fully automatic

  Tengo mas of 150 office maquinas y varios servidorres dentro del esxi host quisiera balancear carga lo mejor q can sin anti el performance of the machine.

  entonces don't be TR leave has half a ponerlo UN mas agresive UN 75% not so is a UN 75% will a comenzar a maquinas por cambio cuando realmente o any mover you need pasarse otro countless

  OPCION cual me be replaced by Recomiendan are in mi tengo mas of 150 escritorios ambiente y virtualizados no quiesiera anti el performance of las vdi

  Saludos,

  If no you puedes enabling urban en no clusters, lo mejor usar pools are (fijar base del reparto en una amount para cada uno y mas al cluster tire what if needed, pero con lo as tiene el otro reserved)

  Lo said a level of vdi. Users con 150, have al menos el repartido total en varios pools por temas performance

• DRS level automation script

  I use DRS in vCenter and it works fine.  I have the fixed level to fully automated and implemented priority 3.   I does not use Update Manager to patch because the company wants one place the observer successes and failures.

  My problem is when Windows patching my guests restarts and DRS puts to migrate due to the additional load of Windows Start, which increases the time required to make the connection.

  Y at - it a command to set manual DRS or lower the priority, so it is not migrate guests when they restart the application of Windows patches during the?

  With powerCLI to set the cluster to the Manual:

  Get-cluster - $mycluster - manual cluster drsautomationlevel - confirm: $false

  And back to fully automated:

  Get-cluster-cluster $mycluster - drsautomationlevel fullyautomated - confirm: $false

• HA and DRS

  I want to confirm something I've heard which seems to contradict what I've learned in the classroom.   If the DRS and HA are implemented on a cluster AND the failure of an ESX Server, the virtual machines on the host CAN live migrate to another host?    I was told in class that VMs will be always powered down if HA is implemented.  So which is true?

  In addition, if the DRS and HA have been implemented on a cluster and we will say I pull the plug on an ESX host... it is not enough time to migrate VMs live, so I'm inclined to believe that's NOT true.

  Let me see if I can summarize-------.

  HA - protects you in the event of a failure of the host - if a host fails (you pull the plug) the virtual machines running on this host will restart on the other nodes in the cluster and if DRS is activated it then make sure that virtual machines draw their resources. The way the cluster hosts know that they are alive is by the HA heartbeat if heart rate is not detected a host of the cluster think the host has failed, but he could not because of network problems - host is then described as being isolated but not bencessaryily down, so virtual machines on it are still running - the cluster tries to restart virtual machines but not power because the VMDK will be locked - this is where isolation answer comes to you can get the Power Down the VMs host to the HA cluster to restrt them (moving) or let them powere gift there is no failure (where they are). VMotion and DRS has nothing to do with VMware HA-

  FT - whicxh is a feature of the Enterprise Plus can have NO downtime in the event of a failure of the host and also protects from the questions of the o/s and - if there is a failure that the VM mirroring resumes instantly with no downtime of fault tolerance.

• Requirements VMware HA and DRS.

  On vmware site I was just brushing my knowledge on VMware HA and DRS and found a conflict. Someone can it confirm please.

  One of the requirements for VMware vmotion and DRS turns "the virtual machine configuration file must not reside on a VMFS located on the shared data store. . . "(Ref: http://www.vmware.com/support/vc13/doc/c2vmotionreqs12.html) "

  But VMware HA says one of the requirements as "cluster-enabled VMware HA, all virtual machines and their configuration files to .

  reside on the shared storage (Fibre Channel SAN, iSCSI SAN, or NAS iSCSI SAN), because you have to

  ' be able to power on the virtual machine on any host in the cluster " (Ref: http://www.vmware.com/pdf/vmware_ha_wp.pdf ( )

  What does that mean? Or the constraint of VMware vmotion is wrong? I'm just confused!

  The first link is-old vMotion applies to Virtual Center 1.3 and ESX2.

  "The virtual machine configuration file should not reside on a VMFS located on the shared data store '... This applies to 2 ESX hosts. At the time, the virtual machine configuration (.vmx) file was located locally on the ESX host, run the virtual machine in/home/default vmware...  This file have been moved to the local directory on the target host during vMotion...

  This was changed to ESX3, who, with Virtual Center 2, introduced also HA...

  For HA to work all the VM files must reside on the shared storage. This makes all slender VM files available to other hosts of clusters at all times. (difficult to extract different files from a host of dead).

• Best practices on UAT HA and DRS

  Dear Guru

  To test HA feature (I have esx 1 and esx2), I'm just saying that the only way to test HA is in the power of one of the esx1 and there are toggled to esx2, assuming that there is no constraint.   Can someone show me what is the best configuration to set on the, for example "allow VM to power it on if viloates contrainst... etc"

  One other scenario-let say I have set up a cluster and activated HA and DRS with resouce pool created.   Assumming If I deseelct DRS, will I be able to retrieve the list resources that I have previously set pool resources assuming that if I select DRS Again?

  Last scenario - let say I have 2 esx server who do not set up to be in a cluster.  If the port of vmotion is enabled on both hosts, am I right to say that I am able to perform a vmotion, even if host 2 did not configure for HA and DRS?

  Enjoy your patienace

  #1 I think that the answer is no. If you disable the DRS, all Resource Pools will be deleted and you will need to re-create if you decided to reactivate the DRS.

  #2-Oui, you can VMotion between two hosts that are not in any cluster, so they are managed by the same VirtualCenter and can see the same data warehouses

  Hope that helps! Please, help me by marking my response as "useful" or "correct", if you feel it is useful!

• Please explain SVmotion (Storage Vmotion) and DRS for storage in simple words

  Friends,

  I little confusing... could you please contact Storage vmotion and DRS for storage in simple words and the important points to remember in this regard...

  Kind regards

  Sirot

  9884106697

  Storage DRS is a feature that you allow warehouses of data aggregated on a single object (cluster) and recommend the implementation of disks in virtual machine based on the performance of the store of data and the available space on the data store.

  The DRS storage uses Storage vMotion to migrate virtual (online) computers from a data store to another to balance data store performance and space.

  You can use Storage vMotion without storage DRS too, moving virtual machine between clusters of DRS storage and warehouses of data even from the local level to the data store shared.

• Disabled - HA and DRS cluster hosts do not appear in vCOPS

  Have a cluster HA and DRS disabled so that each of the 10 hosts act as autonomous.  In vCOPS 5.8 UI, the hosts appear in the accounts for the cluster but cannot explore them or access it from the search box.  Any ideas?  Thank you

• Change the PowerCLI Script to use the DRS and DRS storage

  Hello

  I have a PowerCLI script that specifies a host and a data store to create a new virtual machine, which has served us well. Now we have activated the DRS and DRS storage and I wonder what to change in order to take advantage of these features. Are there commands to specify a cluster and the cluster data store and let the DRS to decide the initial investment for a new virtual machine? At the moment we put all hosts and the warehouses of data as variables and use them in the line below.

  Thank you.

  $newVM = New-VM-name $NewVMname - VM $TemplateName Datastore - $datastore - VMHost $vHost - confirm: $false - location $myName

  You set a Datastorecluster?

  If Yes, then you can replace the value of parameter data with the datastorecluster object store.

  Replacing a VMHost with a cluster is not taken in charge I'm afraid.

  But you can use something like this

  New-VM-name TestVM Datastore - DSC - ResourcePool (Get-Cluster-name mycluster |) Get - Resourcepool - name of resources)

  This will automatically select the VMHost.

  The virtual machine appears in the root of the cluster.

  DSC is the name of a datastorecluster in the cluster mycluster

• Advanced features of ESXi 4.1 - vMotion, HA and DRS.

  Hi all

  I have a dell poweredge 1950 with 2 processors dual core, 8 GB ram and 2 hard drives. I would like to install a virtual laboratory for features in advanced practical such as vMotion, HA and Drs I know I need 2 ESXi host and storage San iSCSI shared to implement.

  I have only 1 physical box that has 1 ESXi host installed. I have the vCenter, iSCSI SAN (openfiler) installed in a virtual machine. I have a laptop that has vSphere client to connect to the ESXi host through vCenter.

  Is it possible to install 2nd ESXi host in a VM on the ESXi host 1 and perform advanced functions as mentioned above. I'd appreciate your suggestions and advice.

  Thank you

  -rmshah5050.

  Can't do anything as an automatic resource pools configuration.

  How much memory assign you to virtual ESXi hosts. To properly configure HA you must assign at least ~2.5 GB to hosts.
