So, the work is complete… Well, this sort of work is never really complete, per se. But, our Hyper-V cluster project is complete enough to call it complete. Make sense?
I have blogged about this saga before, so I’m not going to go into every nitty-gritty detail. But, here is an overview of what we did.
- 2 x Hyper-V hosts in production.
- MD3000i iSCSI SAN providing storage to Hyper-V hosts.
- Virtual Machine Manager used (primarily) for management of Hyper-V hosts.
- 3 x Clustered Hyper-V hosts
- MD3000i iSCSI SAN providing CSV storage to cluster.
- Virtual Machine Manager still being used to manage the environment.
- 1 x 5TB DAS to be re-deployed as storage for our Worship Arts department.
- Brought up a third Hyper-V Host server and attached DAS and SAN.
- Migrated ALL of our VMs onto this one host (scary!!).
- Reinstalled Win2008R2 on original two hosts.
- Created a two-node cluster with these hosts, using the SAN to provide CSVs.
- Migrated all VMs off the interim Hyper-V host and into the cluster.
- Added interim host as a third node in the cluster.
- Tested fail-over, fail-back, Live Migration, etc. etc. etc.
- Sat quietly for a moment, very pleased with the outcome.
- This was my first experience with clustering. It could not have been easier.
- Getting a Hyper-V pass-through disk into a cluster was not as daunting as I was expecting. Just make sure you know of the limitations, caveats, and oddities.
- I like VMM, though I still find I have to go into Hyper-V Manager and Cluster Manager for some things. It’s rare though, which is nice.
- I wish fail-back in the cluster would use Live Migration, rather than Quick Migration. Maybe I’m missing something here.
- I love being able to do maintenance on my Hyper-V hosts without having to ‘down’ my VMs. This is huge!
- Now that our environment has it, I want to maintain an N+1 type environment.
- I sure could use a 4th node in my cluster! And a 5th…
- BackupExec 2010 works really well with the Hyper-V cluster. Yes, the agents aren’t cheap, but what is your data/environment worth?!
During this project, I hit a few snags here and there. Luckily, someone invented the Internets a while ago, so every answer I needed was only one Google search away!
Lastly, I am looking forward to SP1 that should, from what I have read, give me memory-oversubscribe and a few other cool updates.
