Disaster recovery using Vmware SRM

Jump to solution


Hello to all the Smart, Intelligent and Knowledge-sharing Thwackers,

I have been researching and reading and reviewing the forum as well as other material to find an alternative to the Hot-Standby engine for DR implementation. The poll and all comments on the relevant thread indicates that not many people have used it. While HA is a no brainer with local heartbeat, the sole purpose of DR is to get around local limitation and cater to extend the solution to a different site across WAN. This is where is becomes tricky - more chances or split brain, difficult to implement and even more difficult to upgrade/maintain it.

VMware is one of the best things happened to "ITAdminKind" and SRM takes it up a notch further.

My question is - "Has anyone used VMware SRM to implement DR (Active/Standby mode)?"

If NO (after attempting it), why?

If YES:

Did you use VMR or SRA?

Did you protect both application as well as DB servers?

What are the valid points for IP change and other configuration after failover to the DR site? Used a script? Move VLAN over to the WAN site? DNS? any cool trick to make it seemless and have a high RTO and RPO?

Did you use any of DB technologies instead of SRM? like DB mirroring or log shipping?

I am sure answer to this will help many people who are happy to use hot-standby for HA but need a robust solution for DR in a VM based environment.

Thanks in advance.

Do you use Solarwinds over this SRM setup or just SRM in general? Can you share some more details on it please?

Primary protected pollers and then duplicated ones on the recovery site?

Any diagram or other details will be a great help and appreciated!

We have two SRM instances, the first is over a Layer 2 stretch so no ip address change is required. The second instance using the SRM tool itself to change IP address. This means one extra reboot of each VM but it works. We can be running in the DR centre in under 30 mins, so long as we turn off disk checking at boot. This is using netapp SRA.

This is a very good resource

If you do this post in the forum VMware it's easier to have the answer you seek. on the operation of DRaas.

I'm studying the VM tools. And really there is nothing better for them to virtualization.
