Cabling The Hp Storeall 8800 Storage System - HP StoreAll Series Installation Manual

Cabling the HP StoreAll 8800 Storage system

Note the following guidelines when connecting the 8800 to MDL SAS or ENT SAS capacity blocks:
Controller 1 contains ports 1 and 2 in slot 1. Together, these ports form a controller pair.
Controller 2 contains ports 1 and 2 in slot 4. Together these ports form a controller pair.
The initial connection must be made from controller 1 (port 1 in slot 1) on the StoreAll node.
Port 1 of each controller (in slot 1 and slot 4) connects to I/O module A on the capacity block.
Port 2 of each controller (in slot 1 and slot 4) connects to I/O module B on the capacity block.
Port 1 and port 2 of the same controller (either controller 1 or controller 2) should connect to
different drawers in the MDS SAS capacity block.
Each controller pair can support a single MDL SAS capacity block or up to 4 ENT SAS capacity
blocks.
When connecting a SAS chain of up to 4 ENT SAS capacity blocks, port 1 in each controller
pair connects to either I/O module A in the top capacity block or I/O module A in the bottom
capacity block.
When connecting the capacity blocks together, connect I/O module A on each capacity block
in a "top to bottom" order; connect I/O module B in each capacity block in a "bottom to top"
order.
