PowerStore NFS Synchronous Replication of VMware Datastore
Hi,
I saw that the PowerStore can do synchronous replication on a file server level.
I have two questions that I cannot seem to answer from the docs myself:
- Is it supported to create a VMware datastore as an NFS export (VMware file system) and replicate that synchronously across two PowerStore systems as a stretched datastore for a vSphere cluster?
- If so, what is the estimated failover time when one of the PowerStore systems dies unexpectedly?
I know that Metro Volumes exist, but iSCSI/FC is not an option in this setup. Datastores must be mounted via NFS.
No Events found!

Hello,
i cant answer your questsion but .... when working with NFS than there is no VMFS involed. Seconds... syncronisation is one thing... a transparent failer over something different and an automatic transparent fail is completly different.
In the past there was a 3rd. Party Tool from Cluster LION for that automatic failover which based on the PowerStores Metro Volumes.
But i have my doubt that it is supported for vSphere or how vSphere works.
Regards,
Joerg
