Hard Disk Drives
The SBI-7228R-T2F blade unit accommodates up to two 2.5" SATA/SSD hard disk
drives per node, which are mounted in drive “trays”. The drives can be hot-swapped and
removed or replaced without powering down the blade unit they reside in. The four
drives can be used to set up a RAID array (RAID 0 and 1 ). These drives use a blue
color for the Blade HDD active LED. See
Chapter 1 for information on RAID Setup.
For RAID setup see http://www.supermicro.com/support/manuals/ under RAID
Installation Guides for details.
Caution: To maintain proper airflow, both hard drive bays must have drive carriers inserted
during operation whether or not a drive is installed in the tray.
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
