BCDR Solutions Compared - VMware
Posted on 2011-09-10
I'm comparing 4 solutions for a BCDR design and would appreciate any thoughts - I value the opportunity to learn from peers.
Customer has 3 VMware 4.0 ESXi hosts hosting 14 guests. All guests are WIndows servers (2k3-2k8r2) and include 2 2k5 sql servers and 2k10 exchange. EMC nx4 SAN.
Comparing QuorumLabs appliances, Datto Backup appliances, AppAssure and VMware SRM 5.
The appliances are mainly backup/restore (dr) devices but incorporate the option to "instant virtualize" one or more servers.
Compare these for business continutiy to SRM. Configure 2 or more appliances, backup every 15 - 30 minutes and replicate to the co-located appliance(s), Declare a disaster and bring up the DR site by mounting your servers up on the appliances. Access via Citrix or VPN.
SRM will do the same but implements, wll you know, differently. More hardware needed, etc.
Failback many ways with the appliances from incremental restore to bare metal restore depending on the disaster. SRM 5 greatly improves failback from earlier versions.
Which way would you go or is there a better solution. Again, thanks for reading and sharing any thoughts.
