2 SAS cabling for StoreOnce 5500 Systems
This chapter describes how to connect multiple disk enclosures to the StoreOnce 5500 System,
which has two RAID controller cards. It is included at the front of this guide for users who have
ordered a multi-enclosure configuration at installation because they need to understand how to
cable the disk enclosures to the correct RAID controller card.
IMPORTANT:
It is important to plan for expansion when installing the basic system. The
StoreOnce 5500 System Installation Planning and Preparation Guide
provides detailed information
about choosing a suitable location for the StoreOnce 5500 System, as well as size, weight and
power specifications for various expansion options. This document can be downloaded from:
www.hpe.com/info/storeonce/docs
All other StoreOnce Systems described in this guide have a single RAID controller card and
cabling diagrams for these systems are included in
.
NOTE:
Storage expansion steps with the StoreOnce 5500 System are also described in detail
in the
StoreOnce 5500 System Capacity Upgrade Guide
supplied as a printed document with
the product.
Basic installation
In this scenario, the disk enclosure bundled with the head server is installed above the server
and is connected to the RAID controller card in Slot 2. There is a 1U support shelf above the
head server to protect it from the weight of the disk enclosures. This is the installation that is
described in the printed
StoreOnce 5500 Start Here
poster, and is illustrated below.
NOTE:
Within the StoreOnce software this enclosure is identified as Storage Cluster 1 and
volume and pool names have C2 as part of their naming convention, for example: Pool C2_P1
to Pool C2_P6.
