Hi!
In our case we'll use SRM with array-replication. But, is anybody knows the SRM 5.1 bandwidth requirements for communications between Protected and Recovery sites? 10//100 or more kbits needed?
best regards...

Hi ...
The answer to this question mostly comes down to "it depends" ... It depends on the amount of data that needs to be transferred ...
This blog post in two parts might help you in deciding the bandwidth needed to meet your Recovery Point Objective:

Hope this helps.
Hi!
No, my question is not about bandwidth between arrays on Protected and Recovery sites. Question is about bandwidth between SRM servers only
You mean for just the conversation between the two servers? Or between SRM sites?
Conversation only...
As I understand, in case of array-correlation (no matter how it will works) only SRM Protected<->Recovery conversation exist between sites, even if we have active-active configuration (when every site acts as primary and recovery at the same time...) Am i correct?
If you're asking if the SRM traffic itself can have an impact on the bandwidth, then the answer would be, not really ... SRM itself sends little information between sites and therefore generally has no impact on the bandwidth required between sites.
ok, but is it possible to have documentation about it? I understand and believe to you, but for my architect the 'VMware'-document prefer... Is it possible to have such kind of proof?
I haven't seen actual VMware documentation containing numbers, so I think you'll not find official documentation containing minimum bandwidth requirements.
Maybe some whitepapers that contain the needed information, but don't know any off-hand.
