Hi Steve,

Yes, FAS2050 supports 18 SAS disk RAID-DP raid group.

Here is the FAS2000 series Max. raid group sizes including SAS drives: Maximum RAID Group Sizes RAID 6 (RAID-DP(tm)) FC or SAS: 28 (26 data disks plus 2 parity disks) SATA: 16 (14 data disks plus 2 parity disks)

RAID 4 FC or SAS: 14 (13 data disks plus 1 parity disk) SATA: 7 (6 data disks plus 1 parity disk)

Thanks, Mukesh

I went to the NOW System Configuration Guide and it hasn't been published for the FAS2050. I was pointed to another document that lists max raid group sizes for SATA and FC disks, but not SAS.

We are getting a 2050 with 20 SAS disks and I want to know if an 18 disk RAID DP raid group is supported.
