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…
Write-Back Caching
Write-Back caching policy accelerates reads and writes. The read IO path is exactly the same as with Write-Through caching. However, the write IO path is very different. All writes from VMware are written to the in-host cache media without synchronously writing to the backend storage. By writing only to the in-host…
This additional configuration in Veeam is only required if the below condition is true: {[Veeam is configured to do SAN controller snapshots (and not VMware snapshots)] OR [Veeam is configured for ‘Direct SAN Access Transport Mode’]} AND [VirtuCache is in Write Back caching mode for one or more VMs]. If the…
If you plan to use Write-Back policy with write replication, you need to select a network in vSphere for write replication. Here are a few options to create a write replication network. 1. Create a new port group in your existing virtual switch that has two teamed 10gbps NIC ports…
