shared hosting email performance reduced

Our backend storage subsystem used for shared hosting is currently under pressure and is unable to deal with all the requests from customers.

We engaged our storage vendor last Friday and we performed a live failover last Friday night to the secondary node. As a result performance was relatively ok Monday, Tuesday and some of Wednesday this week (June 24-26). However as of 13:30 approx on Friday 28th it is not performing optimally.

We have a level3 engineer from Nexenta logged into the system and he’s trying to nail down the problem. Mostly likely the outcome will be a maintenance window again tonight. This will probably be for 2 hours as a software update is likely.
