Supported drives |
Dell-qualified SAS hard drives, SAS solid-state
drives (SSDs), and Self-Encrypting Disks (SEDs) drives.
Mixing disks of different speeds (7,200
rpm, 10,000 rpm, or 15,000 rpm) and bandwidth (6 Gbps or higher) while
maintaining the same drive type (SAS) and technology (HDD or SSD)
is supported. However, this may affect data transfer performance.
-
NOTE: Though drives
of bandwidth higher than 6 Gbps are supported, drives only run at
a maximum speed of 6 Gbps.
-
NOTE: Mixing HDDs and SSDs
within a virtual disk is not supported. SATA drives are not supported.
|
RAID levels |
0, 1, 5, 6, 10, 50, and 60
-
NOTE: Non-RAID drives are
not supported.
|
Virtual functions |
Four virtual functions to support up to four host
servers
|
Management application |
Dell Chassis Management Controller (CMC).
-
NOTE: Option ROM (OP-ROM)
is not supported. Booting from a shared storage is not supported.
You can only boot from the storage on the server module.
