Expansion Links

Expansion enclosures are connected with the subsystem through the "SAS
Exp." ports. Please see below for matching RAID and JBOD and required
cables.

Expansion Configuration

4.3.1.1
The redundant-controller model, S12E-R1132-4, can connect up to 3
JBODs.
Expansion Link Considerations:

Subnet and Virtual LAN can be created to reduce overheads, to
contain broadcast, and provide access security. LAN configuration is
beyond the scope of this hardware manual.
Multiple arrays or multiple partitions can be created and made
available separately through different IDs or LUNs on the host ports.
The RAID volumes appear as shared storage over the Ethernet
network.
To ensure optimal performance, make sure you connect the iSCSI
RAID to a high speed Gigabit Ethernet network.

Dual-controller RAID to dual-controller JBOD

A 120cm cable may be necessary as an expansion link if you route
the fault-tolerant cables from opposite directions. Routing cables
from opposite directions allows uninterrupted access to the disk
drives in other enclosures when one expansion enclosure fails
among them.
A 120cm is also necessary if you have bend radius concerns in your
rack cabinet. The bend radius for SAS cables is 2.2 inches minimum.
The IN and OUT ports are specified on JBOD controllers' faceplates.
