Waas for DC-DR

[ambi]

Can Waas be used to optimise storage traffic (FC) ?

Requirement is to have a synchronous storage replication between two data centres within a city.  the latency would be less than 5ms between the centres. would there be a real benefit with Waas at such low latency high speed links ??

Hi Ambi,

In WAAS 4.0, there is the "Replication Accelerator" mode that is targeted to do what you want to achieve.

Unfortunately, it is designed to work on WAN links with a latency of 20ms or above so I'm not sure you will get much benefit from a WAAS solution in this case.
