Features
Preface
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 88
).
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
"Configuring
the server" on page 73
.
–
Modular RAID 5/6 controller with "MegaRAID functionality"
(SAS MegaRAID)
RAID levels 0, 1, 10, 1E, 5, 50, 6 and 60 are supported for internal hard disk
drive configurations. As an option, a battery backup unit (BBU) can save the
memory content even if the power fails. Cache memory sizes of 256 Mbyte
and 512 Mbyte are available.
For more information on configuring the controller, see section
"Configuring
the server" on page 73
.
