EMC CLARiiON DAE2 Setup And Cabling Manual

EMC CLARiiON 2-Gigabit Disk-Array Enclosure (DAE2) Setup and Cabling Guide
PARTS CHECKLIST FOR BASIC CONFIGURATION
Before you start, be sure you have available the necessary materials listed
below. Most required parts were provided with your system, but some are
shipped with particular components (and configurations) and others are
shipped separately.
One or more DAE2 disk enclosures
EMC-approved disk drives
For a list of supported RAID disks, refer to the EMC Storage Systems
CX-Series Disk and Software Matrix (P/N 014003111), available on the
Powerlink website.
If your DAE2 is not already installed in a rackmount cabinet
• One or more rails kits, and
• the EMC Rails and Enclosures Installation Guide for 19-inch NEMA
Cabinets (P/N 014003082)
Fibre Channel copper cables for connecting the DAE2 to SPE or DPE2
storage processors, or for connecting multiple DAE2s to each other
(2 per DAE2)
EMC DAE2 Hardware Documentation CD (P/N 068090607)
®
If you will use EMC Navisphere Manager to manage the DAE2 with
an EMC CX-Series storage system
• The Configuration and Planning Guide appropriate for your system.
These manuals are available on Powerlink and the appropriate
Hardware Documentation CD.
• EMC Navisphere Manager Version 6.X Administrator's Guide
(P/N 069001125) available on the EMC Navisphere Manager 6.X
Documentation CD (P/N 068090604).
If you are adding a DAE2 to a Celerra Network Attached Storage
system, be sure you have the appropriate documentation for that
system. You can find Celerra manuals on the EMC PowerLink
website http://powerlink.emc.com. Once logged in to Powerlink,
select Products > Networked Storage> Network Attached Storage
(NAS) > Celerra Systems > Celerra Manuals, Product Guides,
Configuration Guides, etc.
BEFORE YOU START
IMPORTANT Be sure you have completed all of the following site
and configuration preparations before you attempt to set up your
DAE2s.
1. Confirm that your facility has appropriate electrical wiring in
place to accommodate your cabinet's power cables.
The standard 40U EMC cabinet includes two 240-volt ac power
cables. To support all DAE2 high-availability features, you must
connect each power outlet to a different circuit.
2. If you will connect the DAE2 to a storage device such as a CX-Series
storage processor enclosure (SPE) or disk processor enclosure
(DPE2), make sure the device is installed in the cabinet and set up.
Refer to the Setup Guide or Hardware Reference for the device.
3. If you will use EMC Navisphere Manager to monitor DAE2 status,
make sure that Navisphere Manager version 6.1 or higher is set up.
Refer to the EMC Navisphere Manager Version 6.X Administrator's
Guide and the appropriate Release Notes as necessary.
4. If your DAE2 is not already installed in a cabinet, do so now. The
EMC Rails and Enclosures Installation Guide for 19-inch NEMA Cabinets
describes how to install a 3U device like the DAE2 in EMC's standard
cabinet.
You can add DAE2 enclosures to active storage systems without
powering down the existing system.
Step 1
Set DAE2 Enclosure Address(es)

Set the enclosure address (EA) on each DAE2 in a given loop to a unique
number. We strongly suggest that you number enclosures consecutively. Refer
also to the illustrations in Step 2.
NOTE Do not configure an ATA model DAE2 as EA 0, loop 0. ATA
enclosures do not support the boot and SPS requirements of the first disk
array in a storage system.
An integrated disk-and-processor enclosure, such as a DPE2, is always the
first disk enclosure on the first loop (0,0).
Step 2
Set Up Fibre Channel Loops
Connect multiple DAE2s in paired loops. (A Fibre Channel loop is sometimes
called a bus.) One loop connects the SP A/LCC A (right) side of the system;
the SP B/LCC B loop shares disk drives with its counterpart.
Cable the expansion connector (EXP) of a DAE2 to the primary connector
(PRI) of the next DAE2 you want on the loop.
The primary connector of the first DAE2 in the loop is reserved for the storage
processor.
The first configuration on the right shows two redundant DAE2 loops
connected to a 2-Gigabit Disk Processor Enclosure (DPE2).
