Design of disk groups on VxRail E-Series
The cache and capacity disks are predefined in specific disk slots before the VxRail system is delivered to the customer from the Dell factory. The disk slot locations for cache and capacity are fixed when they are made in the Dell factory, and you cannot change them. Figure 5.5 shows the front view of VxRail E660, E660F, and E660N. There are 10 disk slots on these 3 types of VxRail E-Series; disk slots 0 to 7 are used for the capacity tier and disk slots 8 to 9 are used for the cache tier. The capacity disks support SAS/SATA/SSD, and the cache disks support SSD and NVMe SSD:

- Mixing the SAS/SATA/NVMe SSDs in the same disk group is not supported.
- Mixing the capacity HDDs with capacity SSDs in the same disk group is not supported.
- All the capacity disks must be...
