Options for Managing vSphere Replication Traffic on Cisco UCSPosted: November 17, 2014 Filed under: Cisco UCS, SRM | Tags: cisco ucs, ucs, vr, vsphere replication Leave a comment
I was recently designing a vSphere Replication and SRM solution for a client and I stated we would use static routes on the ESXi hosts. When asked why, I was able to 1. discuss why the default gateway on the management network wouldn’t work and 2. present some options as to how we could separate the vSphere Replication traffic in a way that would allow flexibility in throttling its bandwidth usage.
You won’t see listed here Network I/O Control because this particular client didn’t have Enterprise Plus licensing and therefore wasn’t using a vDS. In addition, this client was using a fibre channel SAN on top of Cisco UCS with only a single VIC in his blades. This configuration doesn’t work well with NIOC because it doesn’t take into account FC traffic which is sharing bandwidth with all the Ethernet traffic NIOC *is* managing.
SRM error – failed to recover datastore. An error occurred during host configurationPosted: October 30, 2013 Filed under: SRM, VMware | Tags: An error occurred during host configuration, failed to recover datastore, site recovery manager, srm Leave a comment
I’d like to share an error I was receiving when running test recoveries with SRM 5.1.1 on a NetApp, ONTAP version 8.1.2. The datastores in question were NFS. The error received in the SRM report is consistently in Section 4. Create Writable Storage Snapshot, but strangely, on differing datastores, first datastore 6, then on datastore 5, then back to datastore 6. This is without making changes to the environment in between tests. Weird, huh? The exact error in the report is
“Error – Failed to recover datastore ‘<datastore6>. An error occurred during host configuration.”
