Adding an optional 80-drive DAE

302-003-781

REV 01

July 2017

This document describes how to add an optional 80-drive DAE in

Unity All Flash and Unity Hybrid systems.

You will install the 80-drive DAE from the front of the rack, after installing the snap-in

rails into the selected space in the rack.

CAUTION

The enclosure is heavy and should be installed into or removed from a rack by two

people. To avoid personal injury and/or damage to the equipment, do not attempt

to lift and install the enclosure into a rack without a mechanical lift and/or help

from another person.

Note

You do not have to power off any components to add a 80-drive DAE. If an additional

12-Gb SAS back-end I/O module is required to complete the installation, persisting that

I/O module requires a coordinated reboot of the array.

NOTICE

When Data at Rest Encryption is enabled, only drives that meet at least one of these

requirements can be used: factory new drives, securely erased/sanitized drives, or

previously encrypted drives.

Handling replaceable units

This section describes the precautions that you must take and the general procedures

that you must follow when removing, installing, and storing any replaceable unit.

Avoiding electrostatic discharge (ESD) damage

When replacing or installing hardware units, you can inadvertently damage the

sensitive electronic circuits in the equipment by simply touching them. Electrostatic

charge that has accumulated on your body discharges through the circuits. If the air in

the work area is very dry, running a humidifier in the work area will help decrease the

risk of ESD damage. Follow the procedures below to prevent damage to the

equipment.

Be aware of the following requirements:

lProvide enough room to work on the equipment.

lClear the work site of any unnecessary materials or materials that naturally build

up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers,

and similar items.

lDo not remove replacement or upgrade units from their antistatic packaging until

you are ready to install them.

lBefore you begin service, gather together the ESD kit and all other materials you

will need.

lOnce servicing begins, avoid moving away from the work site; otherwise, you may

build up an electrostatic charge.

lUse ESD anti-static gloves or an ESD wristband (with strap).

If using an ESD wristband with a strap:

nAttach the clip of the ESD wristband to the ESD bracket or bare metal on a

cabinet/rack or enclosure.

nWrap the ESD wristband around your wrist with the metal button against your

skin.

nIf a tester is available, test the wristband.

lIf an emergency arises and the ESD kit is not available, follow the procedures in

Emergency Procedures (without an ESD kit).

Emergency procedures (without an ESD kit)

In an emergency when an ESD kit is not available, use the following precautions to

reduce the possibility of an electrostatic discharge by ensuring that your body and the

subassembly are at the same electrostatic potential.

NOTICE

These precautions are not a substitute for the use of an ESD kit. Follow them only in

the event of an emergency.

lBefore touching any unit, touch a bare (unpainted) metal surface of the cabinet/

rack or enclosure.

Adding an optional 80-drive DAE

Handling replaceable units 3

lBefore removing any unit from its antistatic bag, place one hand firmly on a bare

metal surface of the cabinet/rack or enclosure, and at the same time, pick up the

unit while it is still sealed in the antistatic bag. Once you have done this, do not

move around the room or touch other furnishings, personnel, or surfaces until you

have installed the unit.

lWhen you remove a unit from the antistatic bag, avoid touching any electronic

components and circuits on it.

lIf you must move around the room or touch other surfaces before installing a unit,

first place the unit back in the antistatic bag. When you are ready again to install

the unit, repeat these procedures.

Hardware acclimation times

Systems and components must acclimate to the operating environment before

applying power. This requires the unpackaged system or component to reside in the

operating environment for up to 16 hours in order to thermally stabilize and prevent

condensation.

Refer to the table, Table 1 on page 4, to determine the precise amount of

stabilization time required.

NOTICE

lIf there are signs of condensation after the recommended acclimation time has

passed, allow an additional eight (8) hours to stabilize.

lSystems and components must not experience changes in temperature and

humidity that are likely to cause condensation to form on or in that system or

component. Do not exceed the shipping and storage temperature gradient of

45°F/hr (25°C/hr).

lDo NOT apply power to the system for at least the number of hours specified in

the table, Table 1 on page 4. If the last 24 hours of the transit/storage

environment is unknown, then you must allow the system or component 16 hours

to stabilize in the new environment.

Removing, installing, or storing replaceable units

Use the following precautions when removing, handling, or storing replaceable units:

CAUTION

Some replaceable units have the majority of their weight in the rear of the

component. Ensure that the back end of the replaceable unit is supported while

installing or removing it. Dropping a replaceable unit could result in personal

injury or damage to the equipment.

NOTICE

lFor a module that must be installed into a slot in an enclosure, examine the rear

connectors on the module for any damage before attempting its installation.

lA sudden jar, drop, or even a moderate vibration can permanently damage some

sensitive replaceable units.

lDo not remove a faulted replaceable unit until you have the replacement available.

lWhen handling replaceable units, avoid electrostatic discharge (ESD) by wearing

ESD anti-static gloves or an ESD wristband with a strap. For additional

information, refer to Avoiding electrostatic discharge (ESD) damage on page 3.

lAvoid touching any exposed electronic components and circuits on the replaceable

unit.

lNever use excessive force to remove or install a replaceable unit. Take time to

read the instructions carefully.

lStore a replaceable unit in the antistatic bag and the specially designed shipping

container in which you received it. Use the antistatic bag and special shipping

container when you need to return the replaceable unit.

lReplaceable units must acclimate to the operating environment before applying

power. This requires the unpackaged component to reside in the operating

environment for up to 16 hours in order to thermally stabilize and prevent

condensation. Refer to Hardware acclimation times on page 4 to ensure the

replaceable unit has thermally stabilized to the operating environment.

Handling replaceable units 5

NOTICE

Your storage system is designed to be powered on continuously. Most components

are hot swappable; that is, you can replace or install these components while the

storage system is running. However, the system requires that:

lFront bezels should always be attached to ensure EMI compliance. Make sure you

reattach the bezel after replacing a component.

lEach slot should contain a component or filler panel to ensure proper air flow

throughout the system.

Unpacking a part

Procedure

1. Wear ESD gloves or attach an ESD wristband to your wrist and the enclosure in

which you are installing the part.

2. Unpack the part and place it on a static-free surface.

3. If the part is a replacement for a faulted part, save the packing material to

return the faulted part.

Standard touch point colors

Touch points are component locations where you can:

lGrip the hardware to remove or install a component.

lOpen or close a latch.

lTurn a knob to open, close, or adjust a component.

Standard touch point colors are terra-cotta (orange) or blue.

Note

Within this documentation, the color orange is used instead of terra-cotta for

simplicity.

Table 2 Standard touch point colors

Touch point color Description

Terra-cotta

(orange)

This color indicates that you can perform the task, such as remove a

component with a terra-cotta (orange) lever, while the system remains

powered (up/on).

Note

Some tasks may require additional steps.

Blue This color indicates that a shutdown of the system or component is

required before you can perform the task, such as removing a

component with a blue lever.

Handling disks

Disks are extremely sensitive electronic components. Always handle a disk gently, and

observe the following guidelines:

lFollow the instructions described in Removing, installing, or storing replaceable

units on page 5.

lDo not stack disks upon one another, or place them on hard surfaces.

lMake sure that the replacement disk has the same part number or the part number

of an approved replacement for the faulted disk. The part number (PN005xxxxxx)

appears on the disk. A replacement disk should be the same type (example: SAS,

FLASH) and have the same capacity (size and speed) as the disk it is replacing.

lWhen removing a spinning disk, pull the disk partially out of the slot, then wait 30

seconds for the drive to spin down before removing it.

lWhen installing multiple disks in a powered up system, wait at least 10 seconds

before sliding the next disk into position.

lPlace disks on a soft, antistatic surface, such as an industry-standard antistatic

foam pad or the container used to ship the disk.

Adding an optional 80-drive DAE

Handling disks 7

Adding the new 80-drive DAE

Take the following actions to install the new 80-drive DAE into the system.

Choosing where to install the DAE

Before installing the new DAE, you should determine the placement of the new

enclosure within the rack.

Choose a 3U space in the rack for the new DAE after reviewing the following

guidelines:

lLeave 1U of space at the bottom of the rack for access to cables.

lPopulate all 80-drive DAEs starting from the bottom of the rack before adding

DPEs and other DAEs.

CAUTION

Improper positioning of the 80-drive DAE may cause the cabinet to become

top-heavy and susceptible to falling.

lIf there is already an 80-drive DAE in the rack, place the new DAE directly above

the existing DAE.

lWhen adding a 80-drive DAE to an existing installation, ensure that a 25-slot DAE,

15-slot DAE, or the DPE itself, is not positioned between two 80-drive DAEs. If the

DAE is improperly positioned, it causes a serviceability tunnel and makes servicing

the DPE or DAEs difficult.

Special considerations for adding an 80-drive DAE

The 80-drive DAE supports back-end x8 cabling. However, special steps must be

taken before powering on the system.

If you are connecting the DAE to a 4-port SAS SLIC that requires x8 connectivity,

insert the SAS cable into the 4-port SAS SLIC before persisting the SLIC. The 4-port

SAS SLIC must be persisted with the cable inserted for x8 connectivity.

Note

If the SAS back-end SLIC is powered on without any cables inserted, it is

automatically set at x4 and cannot be used for x8 lane cabling.

80-drive DAE and SLIC port mapping information

BE 0 and 1 can only be x4 and thus will always be back end (BE) 0 and 1.

15-drive, 25-drive and 80-drive DAEs are all valid configurations when connected to

BE 0 and/or 1 as x4.

SLIC BE ports 2 through 5 can be either x4 or x8. They will persist at the time of the

install. To persist x8, at the very least the x8 cable must be in place. The x4 cable does

not have to be in place to be x4.

15-drive, 25-drive and 80-drive DAEs are all valid configurations when connected to

BE 2 through 5 as x4. If they are x4 they will map to BE 2, 3, 4 and 5. If they are x8

they will map to 2 and 4. Only 80-drive DAEs can be connected x8 to BE 2 or 4

therefore an x8 80-drive DAE will always be on either BE 2 or 4.

Field Upgrade Procedure

8Unity All Flash and Unity Hybrid Field Upgrade Procedure

Splitting ports on the SAS SLIC

It is possible to have an x4 on BE 2 and BE 3 with and x8 on BE 4 (ports 2 and 3). It is

also possible to have an x8 on BE 2 (ports 0 and 1) with and x4 on BE 4 and BE 5

(ports 2 and 3).

The mapping of the BE busses is a physical mapping. A DAE’s presence has no effect.

lPhysical ports 0 and 1 of the SLIC will always be bus 2 when configured as x8.

lPhysical ports 0 and 1 of the SLIC will always be bus 2 and bus 3 when configured

as x4.

lPhysical ports 2 and 3 of the SLIC will always be bus 4 when configured as x8.

lPhysical ports 2 and 3 of the SLIC will always be bus 4 and bus 5 when configured

as x4.

Verifying shipping package contents

2. To remove the handles:

a. Push the handle downward to unlock it and outward to separate it from the

chassis.

b. Repeat these steps for the remaining handles.

Working with the portable lift

If the DAE with all of the FRUs removed is being installed, the chassis can be installed

without using the lift. If the DAE is populated with FRUs prior to installing, then this

task requires the use of a portable lift.

The portable lift commonly used by service personnel is manufactured by Alum-A-Lift.

Instructions for this lift are included in the lift kit. Refer to "http://

www.corkc4.isus.emc.com/wiki/index.php/Lift_Tool". which describes the Lift
