PrimoCache with Cluster Shared Volumes

[midnight]

Hello, has anyone got any experience using Primocache on a Hyper-V Host that uses CSV's as the storage for Virtual Servers (vhdx's)?

The path to the Volumes is usually C:\ClusterStorage\Volumex\...... This is a transparent path to a LUN on a SAN.

Will it work with a CSV?
Was it / the host stable?
Was there any noticeable performance increase?

Most of the Hosts will be running Server 2012r2 / 2016 - with Gui. With approx 32GB - 64GB RAM assigned to Primocache - that's the plan anyway.

Some hosts vary from having 2 VM's to 10 VM's - usual fileservers, small SQL Servers, app servers etc.

Any advice would be greatly appreciated.

Thanks.

Hi,

the Version v2.4.0 of PrimoCache (Server Edition) does not Support CSV Volumes - our CSV Volume is not shown in the Dialog when you
want to add a cache to a volume...

The beta Version v3.0.2 also does not allow Cluster Shared Volumes to be cached.

This is a screenshot of mountvol which shows the mounted volumes and their drive letters:


This is what the command line Tool rxpcc shows up:

PrimoCache only supports volumes which are listed in Windows Disk Management. It cannot support symbolic mounted volumes.

Hello,
the volume is listed in Windows Disk Management , but it is reserved by the Failover-Cluster
Would it be possible to support this or is it impossible ?

Theoretically, it is possible to be supported by PrimoCache. We'll check this.

Hello Romex Support,

Thank you,

@thommyf, sorry but we're still working on it. CSVs don't work like local physical disks, and it may not be easy to support it simply with current design of PrimoCache.
