EqualLogic PS6000XV RAID Question
Hello,
We are deploying an EqualLogic PS6000XV and we have one question regarding the array.
The EQL has 16 x 600GB. We have selected RAID 50 and EQL automatically build the RAID for us (it didnt give us any option further).
The net available space became as 7.3TB.
My questions,
- How many volumes of RAID 5 does this storage set up on an automatic RAID 50 ?
- As the net space for a 600GB is 550GB, I imagine that the EQL built two volumes of RAID 50, with that config I would have 7.6GB of net space, where are the other 300GB ?

2*(7-1)*600=7200. By those calculations, you have an extra 100 GB that you shouldn't have. The 14 and 16 drive models (PS50-PSX0X0) have 2 RAID groups for RAID 50. The PSX100 (24 drives) have three unbalanced RAID groups for RAID 50. The PSX5X0 (48 drive Sumo) have at least 4, possibly 5 or 6 RAID groups. I don't know about the new PS6100XS which has 17 10K SAS and 7 SSD drives.
