Hi Rick,  The drives from 0-4 have some reserved area for VNX OE and the space for vaulting purpose. We will be able to create User LUNs from the rest of the space available , which is listed as in your query. We can utilize the maximum space out of the remaining (5-9) drives.  Vipin V.K
Hi Everyone,  I have a VNXe with 10 x 300GB SAS disks. Disks 0-4 are showing a different capacity than 5-9. (220GB vs 268GB) I read this blog [URL] It mentions PSL or Persistent Storage Layout, which apparently accounts for the reduced capacity on some of the disks. I can't find anything in EMC's docs about PSL. Could someone point me in the right direction please, so I can explain the differences in capacity.  Many thanks, Rick
