SC847J Chassis External Connectivity

It is important to understand that this is a JBOD chassis. A JBOD chassis has no

motherboard, but uses an initiating head unit or a host/server unit. A JBOD chas-

sis has an HBA or RAID card to host, and maps the drives in the JBOD chassis

downstream. The head unit’s RAID card cascades to this chassis using an external

SFF 8088 to SFF 8088 cable, such as CBL-0166 as illustrated below.

Below please see block diagram of how the connections are made, internally:

Section 3 – 847 JBOD chassis external connectivity

First it’s important to know that this is a JBOD chassis. This means that there is no

motherboard used in this chassis. It also means that we would need an initiating head unit

or a host/server unit which would have a HBA or RAID card to host and map the drives

in the downstream JBOD chassis. The head unit’s RAID card would cascade to this

chassis using an external SFF 8088 to SFF 8088 cable (i.e. CBL-0166). See picture of

cable below:
