7. JBOD 2000 External SAS Connection Mode Overview
The Intel ® Storage Server System JBOD 2000 Family supports connection to many different
external SAS HBA and SAS RAID controller solutions, to achieve single JBOD connection,
multiple JBODs daisy chain connection, and failover connections. This section provides an
overview of the different options available.
7.1 External SAS Controller Support
Our current and future supported controllers are referenced via our JBOD 2000 Family THOL or
SCT.
SAS connectivity is via the external SAS connectors (SFF8088); both native SAS HBAs and
RAID HBAs are supported.
7.2 External SAS Cable
JBOD 2000 system uses SFF-8088 mini-SAS receptacle, so SFF-8088 mini-SAS cable is
needed when connecting the JBOD2000 to host or cascades to other JBOD2000. The following
figure is an illustration of SFF-8088 mini-SAS cable.
Figure 38. SFF-8088 mini-SAS Cable
According to SAS 2.0 specification, the length of mini-SAS cable has the following rules:

The 6Gb/s SAS cables work up to 10 meters with DFE (decision feedback equalization).

The 6Gb/s SAS cables run at less than 6 meters without DFE.

The 3Gb/s SAS deployments are limited to cable length up to 6 meters.
