Storage-system c

omponents

The AX4-5 series s

torage system consists of rack-mountable

storage-system e

nclosures, 3.5 inches (2U) high, that contain 4 to 12

serial advanced t

echnology attachment (SATA) or serial attached SCSI

(SAS) disk drive

The AX4-5 and AX4

-5SC storage systems use a Fibre Channel arbitrated

loop (FC-AL) or F

ibre Channel switch (FC-SW) as an interconnect

interface to ho

st servers. The AX4-5i and AX4-5SCi storage systems use

the Internet Sm

all Computer System Interface (iSCSI) protocol.

The AX4-5 and AX4-5SC are also called the AX4-5F and AX4-5FSC, respectively. Models with four Fibre Channel host ports per controller are called AX4–5F8 or AX4–5FX, and AX4–5SCF4 or AX4–5FSCX. The AX4-5i and AX4-5SCi are also called the AX4-5I and AX4-5ISC, respectively.

Navisphere® management software manages the storage systems from any qualified workstation on a shared Ethernet LAN. Sophisticated RAID (redundant array of independent disk) technology and data caching prevent data loss in case of component failure. Redundant hardware options provide levels of high availability usually restricted to much larger (and more expensive) storage systems. Besides economical disks, the AX4-5 series storage systems include the following major components:

 A disk-processor enclosure (DPE-AX). A DPE-AX contains one

(AX4-5SC or AX4-5SCi) or two (AX4-5 or AX4-5i) storage processors (SPs), each with:

z One dual-inline memory module (DIMM) z One serial port (mini DB9 connector) for service z One 10/100/1000 Ethernet LAN port (RJ45 connector) for

management

z For the AX4-5 or AX4-5i, one serial port for connection to a

standby power supply (SPS)

z One input/output (I/O) module per SP, each with:

− For the AX4-5 or AX4-5SC, two or four 4-Gbps Fibre Channel host ports with small form factor pluggable (SFP) connectors

Hardware and Operational Overview

Page 3

− For the AX4-5i or AX4-5SCi, two Gigabit Ethernet (GigE) ports

 Two power supply/system cooling (power/cooling) modules

AX4-5SCi DPE-AX (rear view)

AX4-5 and AX4-5i systems include a standby power supply (SPS); a second SPS is optional. AX4-5 and AX4-5i systems support as many as four optional disk array enclosures (DAE-AXs). Like the DPE-AX, each DAE-AX includes two power/cooling modules and can contain a total of twelve disk drives. Instead of SPs, a DAE-AX has two link control cards (LCCs) that manage disks on a single redundant back-end bus.

You can install, upgrade, or replace all of the major storage-system components without professional assistance.

Disk and filler mo

dules

Each DPE-AX inclu

des at least four hard disk drives. The first four

disks, marked 0-3

, are system disks (sometimes called vault disks) and

contain vital sof

tware specific to the physical slot they occupy in the

chassis. Do not m

ove a system disk from its assigned slot to another slot.

Remove a system d

isk only if you need to replace it because it failed.

m(vault)disks

If a drive fails, you can replace it with another while the storage system continues running; software rebuilds the contents of the original disk onto its replacement.

DPE-AX and DAE-AX chassis have twelve slots for disk modules. Any unoccupied disk module slot requires a filler module to maintain air flow.

Disk modules

Each disk module, shown in Figure 6, consists of one disk drive in a carrier. You can add or remove a disk module while the storage system is powered up, but you should exercise special care when removing drives while they are in use.

or LCC on the bu

symbol) and ca

n pass input to the next LCC on the bus through an

expansion co

Power/cooling mo

dules

Each power/cooli

ng module integrates an independent power supply

and blowers into a

single module. The power supply in each module

is an auto-rangin

g, power-factor-corrected, multi-output, offline

converter. The power/cooli

ng modules, A and B, are located above the SPs

or LCCs. They sha

re load currents and provide power and cooling

foranentireen

closure. An SP, LCC, or power/cooling module with

power-related

faults does not adversely affect the operation of any

other componen

t. If one power/cooling module fails, the other

compensates u

ntil the failed module is replaced. If the failed module is

in a dual-SP DP

E-AX, the system also disables write caching. Removing

a power/cooli

ng module from the enclosure causes a cooling fault that

will shut dow

n the enclosure within two minutes.

Hardware and Operational Overview

Page 10

Standby power sup

plies (SPSs)

A 1U, 1000-watt SP

S provides backup power for power supply A. An

optional second S

PS supports power supply B. During a power failure,

the SPSs allow wri

te caching to continue, which prevents data loss. A

faulted or not fu

lly charged SPS disables the write cache. Each SPS rear

panel has one AC i

nlet power connector with power switch, AC outlets

for the DPE-AX S

Ps, and one connector for serial connection to an SP.

he SPS connectors and status lights.

Powerup and power

down sequence

A DAE-AX does not have a power switch. It powers up immediately once it is connected to a live power source.

Powering up the sto

rage system

1. Verify the following:  Master switch/circuit breakers for any cabinet/rack power strip

are off.

 The power cord for power/cooling module A in the DPE-AX

(viewed from the rear, A is the right side of the enclosure) is plugged into the SPS, if present, and the power cord retention bails are in place. In a storage system without an SPS, the power cord for power/cooling module A is plugged directly into a power source.

 The power cord for power/cooling module B is plugged into the

nearest power distribution unit on a different circuit feed than the SPS or module A. In systems with two SPSs, power/cooling module B is plugged into its corresponding SPS.

 In a dual-SP system, the serial connection (sense cable) between

SP A and SPS A is in place. If the system has two SPSs, the serial cable between SP B and SPS B is in place.

 The power cords for the SPSs and any DAE-AXs are plugged

in; the power cords for the A and B sides do not share a power source; and, the power cord retention bails are in place.

 Any other devices in the cabinet are correctly installed and

ready for powerup.

Powering down the

storage system

CAUTION

Never shut down a DPE-AX by disconnecting the AC power cords for its power/cooling modules. Bypassing the controlled powerdown in that manner prevents the system from saving any write cache data to the system drives, and may result in data loss.

1. Stop all I/O activity to the DPE-AX. If the server connected to the DPE-AX is running the AIX, HP-UX, Linux, or Solaris operating system, back up critical data and then unmount the file systems on storage-system virtual disks.

Stopping I/O allows the SP to save any cache data to the system drives, and may take some time. The length of time depends on criteria such as the size of the cache, the amount of data in the cache, the type of data in the cache, and the target location on the disks, but it is typically less than one minute. We recommend that you wait five minutes before proceeding.

2. For a dual-SP system, after five minutes, use the power switch on eachSPStoturnoffpowertoitscorrespondingSP.

SPs with power/cooling modules connected to an SPS power down within two minutes.

3. Push the power button on SPs that are not connected to an SPS:
