Features
The module is connected to the SAS/SATA backplane without cables. This
allows HDD modules to be simply plugged in or pulled out (for further details see
section "Hot-plug hard disk drives" on page
The hard disk subsystem is designed for SAS/SATA, each with one channel for
each hard disk drive.
If the server has a RAID configuration, the HDD modules can be exchanged
during operation (hot-swap).
SAS/SATA RAID controller
The server is available with the following SAS/SATA RAID controllers for
operating the internal SAS/SATA hard disk drives:
– Modular RAID 0/1 controller with "Integrated Mirroring Enhanced"
(SAS IME)
RAID levels 0, 1 and 1E are supported for internal hard disk drive
configurations.
For more information on configuring the controller, see section
