As we have been going along we have been refining the two node Hyper-V Failover Cluster setup.
We are now at the point where the following base configuration would provide full Hyper-V failover capabilities for a very low cost:
- Hyper-V Server 2008 R2 SP1 Host (Requires 2)
- Intel Server System SR1695GPRX2AC
- Intel Xeon Processor X3470, 32GB ECC RAM, Dual 3Gbit SAS Controllers (SFF-3470 connectors).
- No local storage.
- Pair of SFF-3470 to SFF-8088 SAS Cables
- Promise VTrak E610sD Dual Controller RAID Storage System
- 10x 300GB 15K Seagate SAS (we use RAID 10 = 1.5TB usable)
- 2x 300GB 15K Seagate SAS global hot spares.
- Nodes boot from 75GB masked LUN on VTrak to eliminate the need for local storage.
- LUN Masking: Only the node will see its dedicated LUN as available.
With the above hardware configuration we are able to start our 2 node failover clusters at around $18K for the hardware setup.
For any client that currently has two or more servers and are conscious of the need for uptime we are promoting this setup.
At this price, there is no reason why we can’t be deploying Hyper-V failover clusters into most clients that have two good sized servers up for refresh ($6K-$8K/Server) or multiple small ones.
A big plus when talking about failover is the portability of the VMs. We can restore _anywhere_. Because of this portability we can promote our iSCSI backup target setup which then can eliminate the cost of any third party backup solutions.
Our goal is to go full on Windows OS native with as many tools as possible. And so far, we are being quite successful at making it happen.
