We had a change in plans for this weekend as the SBS 2003 to SBS 2011 migration we were supposed to be running this weekend will not start until this coming week.
So, we now have a day to test run putting together a Hyper-V Server 2008 R2 cluster based on the following:
- Two Intel Server System SR1695GPRX2AC servers.
- Intel Xeon Processor X3470, 32GB ECC Kingston RAM, RS2BL040 RAID + BBU, 300GB 15K SAS x4 in RAID 5, dual external Intel SAS connectors (2x AXXSASIOMOD).
- One Promise VTrak E610sD RAID Subsystem.
- Our demo purchase unit was the E610sD but the configuration will also work with the E310sD unit as they are identical other than the number of drives the unit can hold.
- Four Adaptec 2231500-R mSASx4 cables.
When assembling the Intel Server Systems SR1695GPRX2AC it is important to note the SAS ID and position that particular SAS Module was installed into. We would then have a label with that SAS ID installed above the SAS port on the back of the server to simplify routing the Adaptec SAS cables to the Promise VTrak.
With that information in hand we will be better able to figure out the LUN Mapping when configuring the Promise VTrak unit storage for the cluster nodes.
The primary goal for this huge expenditure on our part in the way of time and product purchases is to verify and test it on behalf of our clients.
If our configuration and testing proves successful then we have three network refreshes over the next few months that we will be recommending this configuration for (or 1U/2U dual Intel Xeon Hex Core E5645/E5649 based nodes).
We see this High Availability configuration as a less expensive alternative to the Intel Modular Server where the IMS just does not make business sense or financial sense.
