Preface
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 Embedded MegaRAID software (SATA Software RAID) supports RAID levels 0, 1 and 10.
For more information on configuring the controller, see section "Configuring the onboard SATA controller" on page 79.
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.
IFor 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" (SAS MegaRAID) for SAS1.0 and SAS2.0
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 size of 512 Mbyte is available.
IFor more information on configuring the controller, see section "Configuring the onboard SATA controller" on page 79.
Further information on SAS/SATA RAID controllers is provided in the "Modular RAID Controller Installation Guide" (on ServerView Suite DVD 2 under Industry Standard Servers - Expansion Cards - Storage Adapters - LSI RAID / SCSI Controllers).
