Hard drive options
The storage enclosure supports up to 10 SFF SAS drives. Always populate hard
drive bays starting with the lowest drive number ("SAS and SATA drive
numbers" on page 10
).
SAS and SATA hard drive guidelines
When adding hard drives to the storage enclosure, observe the following general
guidelines:
• The system automatically sets all drive numbers.
• If only one hard drive is used, install it in the bay with the lowest drive
number ("SAS and SATA drive numbers" on page 10
).
• Hard drives must be SFF types.
• Drives must be the same capacity to provide the greatest storage space
efficiency when drives are grouped together into the same drive array.
NOTE: ACU does not support mixing SAS and SATA drives in the
same logical volume.
Installing a SAS or SATA hard drive
1. Power down the storage enclosure (on page 14).
