i am on a restricted budget , management doesnt agree on replacing the old gear i am looking to replace a ML350 g6 (e5645 with a p410i raid card and 15k sas disks (300 GB raid 1 , 600 GB raid 10 ) with the server of my domain controller : ML350p g8 ( e5-2650 v2 with a p430 raid card - 2GB cache ) and 15k 12GB sas disks . my backup dc is up and running - i will clone the current DC to a small computer - test for 1 week or 2 - then clone the SQL to the old DC ( g8 )
is this a good idea in general ? would the user feel the difference ? should i get 2 SAS ssd ( like the seagate nitro ) in raid 1 for the sql ( i think i can convince management to pay a bit )
