Hello,
I have a problem with an infrastructure that we built.
My client needs to archive its emails with GFI mail archiver for Exchange 2010
we built a vmware cluster 5.5 with two isci link per host and a ps 4100 with 12 900 go sas 10k
The Consultant who did the equalogic installation recommended a raid 50.
Now we can observe a lot of latency on the datastore of the vm with gfi mail archiver and on the datastore of the vm exchange 2010.
my view is that the gfi product that continuously exchange index the logs create latencies.
if i create and other raid, raid 10 for the exchange databases and logs (is the prerequisites) i think i will recover normal access.
But my question is : if i build a raid 10 with 4 disks, can i build later an other raid (raid 6, 10) prep to follow my raid 10 ?
