We are migrating a client's lab management environment to Windows Server 2012 + SCVMM 2012 SP1. We have three physical hosts that we are using for this purpose. The current/old configuration of the environment was three standalone Hyper-V hosts banded together with SCVMM (Windows and VMM version 2008R2).
With the new configuration, we're hoping to implement some level of clustering to help with Live Migrations and provide an HA set of environments. Since there are so many options as far as clustering goes, I would like some help deciding which option is "best".
Three hosts are all less than two years old--dual Xeon with about 100+ GB of RAM in each. They each have 2x10K RPM SAS drives for the OS in RAID-1 and four more 2TB 7.2K RPM SAS drives for data (one is in RAID-5 others configured in RAID-1 but these can change). We also have an EqualLogic PS 6100X SAN connected using a separate set of switches.
As mentioned, these servers will be used for a TFS 2012 Lab Management infrastucture with different environments with a total of ~100 VMs each with snapshots, and all that other good stuff. We are currently thinking of clustering the Hyper-V across the three hosts and using the SAN for storage. My questions are as follows:
1. a) With the above configuration (clustering Hyper-V), what will happen to the local disks? Will they be available for use as non-HA storage?
b) Can the local disks be pooled together to act as HA storage (using CSV, SoFS, SMB3)? Or is running two different clustering technologies on the same servers not supported/recommended?
2. Is there a better way of achieving HA than Hyper-V clustering?
I understand that SCVMM has a method for creating clusters out of standalone Hyper-V nodes.
3.a) Am I right in this understanding? Is this a viable stand-in for Hyper-V clustering?
b) What are the implications of this (pseudo-)cluster configuration?
I've found a lot of how-to guides on setting up different types of clusters, but not any comparison of them. Any help would be greatly appreciated.
