Veritas Global Cluster Solution VS ESXi VMware with SRM
One of our client has a plan to go on virtulization.
- To my knowledge two ESXi hosts with a SAN attached can give local failover of VM's from one ESXi host to another ESXi host. If we add VMware SRM(Site Recovery Manager) product between these two ESXi hosts(PRIMARY) and one ESXi host (DR) , we can establish a Global Cluster(In Symantec term) and through above solution all VM's which exist at PRIMARY site can failover to DR site if PRIMARY site goes down.
- For establishing this environment we need the licenses of three ESXi hosts, two Vcenters and one SRM.
- This solution also has a feature like fire drill in SFHA.
- This solution provide failover on ESXi host failure, OS failure or any kind of hardware component failure. It does not have a super feature which can detect application failure. For this Symantec has a Application HA. The Application HA integrates with the above solution and provide failover on application failure as well.
So to my knowledge in the above virtulization scenerio we can only eligible to propose Application HA. As the above solution can provide best response for Hardware/OS failure.
Correct me if I am wrong for any point mentioned above. Suggestion required if we can improve the above solution with the help of Symantec product(s).
