Features
– For up to eight 2.5-inch SAS/SATA hard disk drives:
Up to eight SAS HDD modules can be used in the drive cage. Each HDD
module can accommodate an SAS hard disk drive with a 2.5-inch format.
The modules are connected to the SAS backplane wirelessly. This allows
HDD modules to be plugged in or pulled out easily.
The SAS hard disk drives are controlled by an integrated SAS PCI controller.
If the server has the corresponding RAID configuration, HDD modules can also
be replaced during operation.
Onboard SATA controller
A SATA controller is integrated on the system board; up to four SATA hard disk
drives can be connected to the controller. The LSI SATA RAID software
supports RAID levels 0 and 1.
I
The controller has its own configuration utility. More detailed information
may be found in the "LSI SATA Software RAID User's Guide" (on the
ServerBooks DVD under "Controllers").
If required, RAID-Level 5 can be added to the RAID functionality using an
activation key. If the server is ordered with this RAID option, the activation key
is included on the system board by the manufacturer. As a result, RAID levels
0, 1 and 5 are available.
PCI SAS controller
To run a maximum of eight SAS hard disk drives, the server is shipped with one
of the following PCI SAS controllers:
– PCI SAS controller with "Integrated Mirroring Enhanced" (IME)
IME supports RAID level 0, 1 and 1E configuration of the internal hard disk
drives.
I
The controller makes a separate utility available for IME configuration.
Further information is included in the "Integrated RAID for SAS User's
Guide" (on the ServerBooks DVD under "Controllers").
