When new end user VMs are provisioned in Horizon VDI and these VMs use Instant Clones and/or App Volumes, the end user VMs get assigned the same UUID for a brief period (duplicate UUID), as a result cache operational state of ‘Write-Back’ is not applied to these VMs, only ‘Write-Through’…
VDI
VirtuCache plugin for vCenter Flash client doesn’t show correct performance data (latencies and throughput) when the VM is a Horizon or XenDesktop VDI VM (using Linked Clone), Xenapp VM (that uses a Linked Clone base disk) or a VM that has a snapshot, in ESXi 6.0 and 6.5. This is…
Linked Clones, persistent and non persistent VDI, Instant Clones, AppVolumes, vGPU and other advanced features of Horizon View VDI are supported. The only feature in View we don’t support is VSA (View Storage Accelerator). VSA caches VM disk data to Host memory, and hence it competes with VirtuCache. But it…
Instant Clones are a Horizon View feature that allows fast provisioning of VMs versus Full or Linked Clones. This is so because the Instant Cloned VMs share the memory and disk state of the parent VM. VirtuCache supports Instant Clones. The only thing to watch out for is View Storage…
Terms to Note. ‘Write-through’ caching policy in VirtuCache is where only reads are accelerated. ‘Write-back One Replica’ is a caching policy where both reads and writes are accelerated. And the writes are replicated to cache media in another host in the same ESXi cluster. Step1: Deploy VirtuCache OVA. Import the VirtuCache…
For Driver version 289 and earlier, if you see low cache hit ratios, you should restart VirtuCache once after installation. This is for VMware View deployments using Linked Clones only.
