RX 300 S6
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 disk drives" on page 100 ).
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) for SAS1.0
RAID levels 0, 1 and 1E are supported for internal hard disk drive
configurations.

For the Japanese market only RAID level 1 is supported for internal
hard disk drive configurations.
– Modular RAID 0/1 controller with “MegaRAID functionality”
(SAS MegaRAID) for SAS1.0 and SAS2.0
RAID levels 0, 1,10 and 1E are supported for internal hard disk drive
configurations.
– Modular RAID 5/6 controller with "MegaRAID functionality"
