A prerequisite to installing VirtuCache is that all other host side caching software be uninstalled. Infinio is one such host side caching software, recently end-of-lifed. Below are steps to ensure that Infinio is indeed removed from the ESXi host. SSH to the ESXi host and make sure the below command doesn’t…

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…
You would need 5-20% of storage capacity used by all the VMs in the host as cache capacity. This ensures high cache hit ratio (>75%). This is usually not a problem when using SSDs since SSDs are high capacity. However when using host RAM, you might not have adequate amounts…
UPGRADING VIRTUCACHE DRIVER Upgrading or patching VirtuCache driver software requires you to completely uninstall the old version and reinstall the new version. Please follow the below steps to do so. Step 1 : Either via VirtuCache GUI or CLI, pause caching on all hosts in the cluster, one host at a…
Step 1: If your VirtuCache license has expired, then skip this step. If your VirtuCache license has not expired, then either via VirtuCache GUI or CLI, pause caching on all hosts in the cluster, one host at a time. Before proceeding to the next host, make sure that caching is…

VirtuCache’s permanent license file is tied to the VMware host System UUID. System UUID is a unique ID assigned to the physical ESXi host by VMware. Please send us the System UUID for each host that you want the permanent license for. There are two ways to get the System…
The hosts need to be in an ESXi cluster for VirtuCache GUI to work. If VirtuCache is installed only on one host, then Datastores won’t show in VirtuCache GUI, but the VMs will show and you can apply caching policies at the VM level. Two or more hosts should be…
VirtuCache license key file is of the type lic_vnx2*.vib The key is installed using the below command: esxcli software vib install -v "file:///vmfs/volumes/[datastore name]/lic_vnx2*.vib" where [datastore name] is the Datastore location the vib has been copied to. In case you are updating an existing key (that might be temporary, permanent, expired,…
