Hello everyone,
i have end to setup the infrastructure with SRM and VReplicator. We have in sync different VMs without issues.
In the coming weeks our customer will want to do a real DR test with failover and failback (to do within the day).
We have tested the SRM process with a single test VM and everythin worked well (planned migration, reprotection, 2nd planned and reprotection).
The only problem detected is the long time to do checksum for the reprotection. For the test VM it took 10-12 minutes; in this case it's no much time but for the real DR, we have 10 TB of data to move from Primary to DR Site; if the checksum time is directly proportional to the size of the data, to complete checksum we need some days and this mean that the production will stay on the DR site for some days.
To avoid this risk and issue, we have in mind to use SRM with the Test DR function. Obviously we will have some manual activities to do but, when the test will be finished, we can clean the environment avoiding reprotect phase. Our idea is:
- power off on Primary Site
- run SRM Test DR
- change routing from Primary to DR site
- test access to DR test environement
- test environment form customer
- when the test will declared finsih cleanup Test DR
- change routing on Primary SIte
- power on Production VMs
What do you think about it? Is it feaseable? Have you some suggestion?
Thanks
Vincent
