I'm about to buy a new server. There is a local distributor here and
they offered good prices. The server will have 2 SAS disks in RAID-1 and
8 or 10 SATA 2 disks in RAID 1+0. Others told me that I MUST ask the
hardware list before I buy it. Here is their opinion:

And here is the hardware:
- Boxed Intel Server Board S5000PSLROMB with 8-port SAS ROMB card
(Supports 45nm processors (Harpertown and Wolfdale-DP)
- Intel® RAID Activation key AXXRAK18E enables full intelligent SAS RAID
on S5000PAL, S5000PSL, SR4850HW4/M, SR6850HW4/M. RoHS Compliant.
- 512 MB 400MHz DDR2 ECC Registered CL3 DIMM Single Rank, x8(for
s5000pslromb)
- Intel® RAID Smart Battery AXXRSBBU3, optional battery back up for use
with AXXRAK18E and SRCSAS144E. RoHS Complaint.
- 4-drive SAS/SATA backplane with expander (requires 2 SAS ports) for
SC5400BRP and SC5400LX (two pieces)
The basic question is:
- how well is this configuration supported in FreeBSD 7?
- is this RAID controller fast and reliable with 10 or more disks? Can
it take advantage of the disks, or should I use a different controller?
Thanks,
Laszlo
