Replication of Virtual Infrastructure to a DR Site
Hi there Experts,
Assuming that I have 2 identical vSphere infrastructures (servers/storages/networki
in 2 different countries and there are connected each other via an internet line.
So there is the Site-1 and the DR-Site-2.
Scenario A:
-All users are connected and using only Site-1. Every afternoon the Site-1 replicates to DR-Site-2.
-In case of Site-1’s failure the users will be redirected to DR-Site-2.
-Once the Site-1 is operational again the replication procedure will be reversed and the DR-Site-2 will send the “new changes” to Site-1.
-Once they are both synced the users and replication will switch back to Site-1.
The above scenario would be applicable with replication software (i.e. veeam)
and given that the internet line is fast enough, the RTO would be normally less than a day.
Scenario B:
- A group of users are connected to Site1 and the rest group of users are connected to DR-Site-2.
Question1: Are the logical assumption of Scenario A correct?
Question2: What kind of network equipment, software and network line would be required in order both Sites to be synchronous at the same time?

Look at VMware replication and SRM (site recovery manager

Dear Aaron,
Thank you for joining the question.
As far as I know the VMware replication and SRM are suitable for DR sites and recovey.
But what type of Software do I need in case that Site1 and Site2 are working in parallel?

SRM can be used in an active active setup, where site 2 can failover to site 1 and site 1 can failover to site 2, and the replication will work both ways

Dear piedthepiper,
Thank you for your reply!
Could you provide me relevant documentation??

I have provided details on bi directional relationship including a link to Mike Lavericks vmug wiki on the subject

Thank you for the info!
Sorry for the delay I totally forgot about this till the reminder came up! I would recommend Mike Lavericks book on SRM, eve though its for 5.0 its core details remain the same and are valid
