I have a question about how to setup RAID array and if this is possible at all.
So here is what I have:
CPU: 2x Quad-Core X5560
motherboard: Intel S5520HC with attached hardware raid AXXROMBSASMR (LSI 1078 4-port SAS HW RAID controller)
memory: 6x4GB DDR3 1333Mhz
Hard-drives: 2x 300GB Seagate Cheetah 10k rpm SAS (RAID 1)
So what I want is to add 2 new SSDs, but with the following configuration:
The current SAS disks should stay in RAID 1 (mirror)
The new SSDs should be configured as RAID 0 (strip)
At the end I should have two partitions - one with the old drives and the other one with the SSD. Is this possible with only one RAID controller?
If you can connect all 4 disks on the same RAID controller (so if the RAID supports 4 disks or up), I don't see why it wouldn't work
From what you mention above it will be possible.

Yes most new raid controllers should support this I see it done all the time. More than one RAID set... 1 + 0, or 1 + 5, 1 + 10, etc
