We currently have a HP Proliant ML310 G5 running 2x 250Gb SATA hard drives in RAID 1 from the on-board RAID controller. This currently runs the OS, SQL Server and holds the SQL databases/transaction logs. We are considering purchasing a HP Smart Array P400 Controller (405132-B21) and 2x HP 300GB SAS Hard Drive (516814-B21) to hold the SQL databases/transaction logs. Is it possible to migrate/physically move the current SATA array from the on-board RAID controller to the new controller without losing data, add the two new SAS drives (creating a new RAID 1 array) so that we can then move the SQL databases/transaction logs to the new array. If this is possible, how would we do that? Many thanks in advance. Regards, Shaun Herridge – IT Manager.
