Chapter 4: Blade Module Features
Memory Support
The SBA-7121M-T1 blade module supports up to 64 GB of ECC Registered DDR2-800/
667/533 SDRAM in eight DIMM sockets. See Section 3-5 for further details on
mainboard memory installation.
Hard Disk Drives
The SBA-7121M-T1 blade unit accommodates up to two 3.5" SATA hard disk drives,
which are mounted in drive “carriers”. The drives are hot-swappable and can be
removed or replaced without powering down the blade unit they reside in. The two
drives can be used to set up a RAID array (SATA RAID 0 or 1 only) or JBOD. These
drives use a yellow color for the Blade HDD active LED.
