Memory Support
The SBA-7142G-T4 blade module each supports up to 256 GB of ECC Registered
DDR3-1600/1333/1066 SDRAM or 64 GB of ECC Unbuffered DDR3-1600/1333/1066
SDRAM in sixteen DIMM sockets. See Section 3-5 for further details on mainboard

Hard Disk Drives
The SBA-7142G-T4 blade unit accommodates up to four 2.5" 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 four
drives can be used to set up a RAID array (SATA RAID 0 or 1 only) or JBOD. These
drives use a blue color for the Blade HDD active LED.
WARNING: Enterprise level hard disk drives are recommended for use in Supermicro
chassis and servers. For information on recommended HDDs, visit the Supermicro WEB
SITE at http://www.supermicro.com/products/nfo/files/storage/SAS-1-CompList-110909.pdf.
WARNING: To maintain proper airflow, both hard drive bays must have drive carriers
inserted during operation whether or not a drive is installed in the carrier.
