Re: After upgrade to SAN IQ 9.5, write peformance issue
it is... it has to be that way... if you are synchronous the write doesn't "count" until it exists at both sites. That definitely adds to latency since the write has to go to both sites and be confirmed at both sites, but that is the definition of synchronous... otherwise it would be asynchronous.

Re: After upgrade to SAN IQ 9.5, write peformance issue
Hi, is this still an issue? I was thinking of upgrading our SAN's from 8.5. Should I just go to 9.0 then?

Re: After upgrade to SAN IQ 9.5, write peformance issue
Yes we still have a problem, a case is still open which is now with the HP VMware team as the storage team think everything is OK with the SAN. Are you running asynchronous multi-site configuration Besty_Boy?

Re: After upgrade to SAN IQ 9.5, write peformance issue
2km tells us nothing. How are they linked? Bandwidth?
I only run a single site cluster, but as far as i can tell 9.5 has not affected the performance (SCOM logging confirms this)
