Morning,
The SAN front end was one of the first places I looked after we had managed to get everything back up again. All lights were green but on further investigation there were 'some' disk errors but nothing that could lead to data loss, apparently. Hence the ticket open with VMware.
Our SAN is a Fujitsu DX90 S1 which is struggling with our environment. It does have features such as remote copy but it's not licensed and if we were to spend money on licensing something like that then we may as well get a newer bit of kit - that's our way of thinking anyway. Something which is well within it's life expectancy, is still supported and carries those sorts of features.
Also RAID 0 is a little bit too scary for us. We have a number of RAID 10 datastores but it just so happened that all of this took place on one of the RAID 5's.
