1-2 SAS
Expander
The SBB 937R-E2JB includes two BMB-937-JB expanders, which are mounted on
hot-swappable trays. The BMB-937-JB utilizes the LSISAS2x36, which is a 36-port,
6 Gb/s SAS expander.
Cascading
Each BMB-937-JB has a SAS-IN port and a SAS-OUT port, which in turn are con-
nected to an I-SAS port at the rear of the chassis. The I-SAS port may then be
used to cascade to another system (must be cascaded to a system with a proces-
sor and memory).
SAS
The LSISAS2x36 is a x36 expander that provides SAS 2.0 support. RAID 0, 1, 10
and 1E modes. Refer to the following ftp site for setup guidelines: <ftp://ftp.super-
micro.com/driver/SAS/LSI/LSI_SAS_EmbMRAID_SWUG.pdf> and Supermicro's
web site for additional inmformation < http://www.supermicro.com/support/manu-
als/> (RAID is supported by third-party software.)
1-3 Server Chassis Features
System Power
The SC937 features a redundant Gold Level 700W power supply composed of two
separate power modules. This power redundancy feature allows you to replace a
failed power module without shutting down the system.
SAS/SATA Subsystem
The SC937 supports up to 16 3.5" SAS drives. These drives are hot-swappable
units and are connected to a midplane that provides power and control.
Notes:
The operating system connected to the SBB system must have RAID support
to enable the hot-swap capability of the SAS drives. As an alternative to SAS drives,
3.5" SATA drives can be supported via an interposer (AOL-LSISS9252).
Front Control Panel
Two control panels are included on each end of the SBB 937R-E2JB to provide you
with system monitoring and control. LEDs indicate system power, cascade status,
