Estimated Installation Time

You should be able to install the FlashArray in approximately

one hour and 15 minutes.

Preparing for Installation

The FlashArray chassis weighs 37.8 kg (83.2 lbs.),

DirectFlash Shelves weigh 39.8 kg (85.8 lbs.), and

expansion shelves weigh 20 kg (44 lbs.) each. Make

arrangements for safe lifting during installation.

Make sure you install DirectFlash Modules, Flash Mod-

ules, or blanks after rack mounting each chassis. The

FlashArray chassis with modules installed weighs

43.2 kg (95.2 lbs.).

Make sure that the rack can support the total weight of all

installed equipment including cables and rails (approx-

imately 48.5 kg or 107 lbs.), and that the total weight is

within the floor loading limit.

Have all necessary Fibre Channel and Ethernet cables

(not supplied by Pure Storage) available.

Verify that front and rear rack mounting posts are

between 61 and 91 cm (24-36 in.) apart, and that you

have 3 RU (13.3 cm or 5.25 in.) of vertical rack space for

the FlashArray chassis and 2 RU (8.9 cm or 3.5 in.) for

each expansion shelf.

Verify that the installation environment

lIs within the operating temperature range of 5-35°C.

lDoes not have airflow ducts aimed directly at any

FlashArray chassis, controller, or shelf.

Have a local console (VGA monitor and USB keyboard

or a computer with terminal emulation capability) avail-

able in case it is required for software configuration or

diagnosis.

Make sure that cable lengths are adequate by mounting

the chassis and shelves in a contiguous stack as shown

in the DirectFlash Shelf, Expansion Shelf, and Add-on

Shelf Quick Installation Guides.

Before unpacking, inspect packages for shipping dam-

age. If damage is present, photograph it and contact

Pure Storage Technical Support before proceeding.

Save cartons and packing material in case return ship-

ment to Pure Storage is necessary.

Save all tools in FlashArray kit.

1. Unpack the FlashArray

Verify that the FlashArray package contains the items shown in Figure 1.

Figure 1. Unpacking the FlashArray

Planning the Installation

Mount heavier equipment lower in the rack. A fully loaded FlashArray chassis weighs 43.2 kg (95.2 lbs.). If possible, install

the chassis below other devices in the rack.

2. Install the Rails

1. (Square-hole racks only) Install the #10-32 cage nuts (from

the Accessory Kit) on the front of the rack, as shown in Fig-

ure 2.

On round-hole racks, use clip nuts (not provided by Pure

Storage, Inc.) instead of cage nuts.

The FlashArray includes two rails, labeled right and left.

The rails have locating pins (for square- and round-hole

racks) or positioning studs (visible if you unscrew and

remove the locating pins for threaded-hole racks) that you

align with the holes in the rack.

2. Install one of the two rails (the installation order does not

matter) by pulling the spring-loaded lever back and inserting

the locating pins or positioning studs in the front mounting

post at the desired height. Release the lever once the rail is

in place. See Figure 3.

3. Extend the rear of the rail until the locating pins or pos-

itioning studs reach the rear mounting post, and press the

rail into the rear post until the latch engages. See Figure 4

(left rail shown).

Install the rear screws only. Front screws are installed later.

4. (All rack types) Secure the rear of each rail to the rack with

the screws provided in the Accessory Kit. One screw is

provided for the rear of each rail. Use the second or fifth

hole up from the bottom of each rail (shown going into the

fifth hole on Figure 4).

5. Repeat 1–4 above to install the second rail.

Make sure to install the rear of each rail into the post holes

that are at the same height as the holes being used on the

front post. Otherwise, the chassis might slide off the rails

causing personal injury and damage to the FlashArray.

3. Mount the Chassis in the Rack

The FlashArray chassis weighs 37.8 kg (83.2 lbs.) before you install DirectFlash Modules or blanks. Make arrangements

for safe lifting during installation. Pure Storage recommends two people for this procedure.

1. Remove the chassis from the antistatic bag. With one person on each side, lift the chassis by the handles and slide it onto

the rails until the rear handles are two inches from touching the rack.

2. Support the front of the chassis while resting the rear on the rails, and remove each rear handle. See von Figure 5.

Figure 5. Mounting Chassis in Rack

FlashArray Quick Installation Guide

40-0154-01 Page 2 of 6 October 12, 2018

3. Mount the Chassis in the Rack (Cont'd)

3. Continue to slide the chassis on the rails until the front

handles are two inches from touching the rack.

Continue to support the front of the chassis as you

remove the front handles. See won Figure 5.

4. Slide the chassis completely into the rack so that the

chassis ears are flush with the front of the rack and the

slam latches lock into place. See Figure 6.

5. (Square- and round-hole racks only) Secure the front of

each rail to the rack and chassis with the screws

provided in the Accessory Kit. One screw is provided for

each rail.

To install the screws, open both slam latches on the

chassis front panel and thread the screws through each

slam latch hole. Tighten the screws, securing the chassis

to the rack and the attached cage nut (installed in step of

"Install the Rails" on the previous page) or clip nut (for

use with round-hole racks and not provided by Pure Stor-

age), and then close the slam latches. See Figure 7.

(Threaded-hole racks only) Secure the front of each rail

to the rack with screws that fit the rack's threaded holes.

For example, if the rack has #10-32 threads, you can use

the screws provided in the Accessory Kit. If the rack has

threads of another size, you must obtain matching

screws.

4. Install DirectFlash Modules, Flash Modules, or Blanks

Install DirectFlash Modules, Flash Modules, or blanks in groups of 10. Do not alternate module types. DirectFlash Module

and Flash Module labels show the capacity in terabytes (see Figure 8).

Make sure all unused slots are filled with blanks.

1. Install DirectFlash Modules, Flash Modules, or blanks (10 or 20) into the chassis slots from left to right, starting with slot 0.

2. Make sure that DirectFlash Module, Flash Module, or blank front panels are flush with the FlashArray front panel. Check

that the latch on each module has engaged by pulling gently on it until you feel resistance.

5. Connect Host, Replication, and Management Cables

Connect each controller (CT0 and CT1) to a separate storage area network (SAN) and replication fabrics (A and B in

Figure 9) to ensure redundancy.

Depending on the customer order, the quad-port mezzanine can be equipped with either an Ethernet or SAS card,

and the PCIe slots can be equipped with Fibre-Channel or Ethernet cards.

1. Use customer-supplied cables to connect host ports FC0 through FC13 or ETH4 through ETH5 and ETH10 through

ETH17 (labeled SAN in Figure 9) to SANs as directed by the customer. Leave unused ports unpopulated.

2. Connect customer-supplied 1-GbE cables to management ports ETH0 and ETH1. Alternatively, you can use ETH1 for

1-GbE replication.

3. Connect customer-supplied 10- or 25-GbE cables from ports ETH2 and ETH3 (labeled REPL A and REPL B in Fig-

ure 9) to replication network switch ports.

4. If the controller has an Ethernet card in the quad-port mezzanine, you can connect ETH6 through ETH9 to DirectFlash

shelves. See the DirectFlash Shelf Quick Installation Guide for more information.

If the controller has a SAS card in the quad-port mezzanine, you can connect SAS0 through SAS3 to expansion

shelves. See the Expansion Shelf Quick Installation Guide for more information.

5. After connecting, pull gently on the cables until you feel resistance to ensure they are secure.

Repeat steps 1–5 for the second controller.
