Introduction

This guide provides information about initial hardware setup, and removal and installation of customer-replaceable units (CRUs) for the QXS G2 systems (RAID chassis and expansion chassis).

The QXS G2 systems converged network controller (CNC) I/O modules has the following host interfaces available:

• Fibre channel (FC) SFP option supporting 8/16 Gb

About This Guide

• iSCSI

• SFP option supporting 10GbE

• Copper RJ-45 SFP option supporting 1GbE

The QXS G2 systems are SBB-compliant (Storage Bridge Bay) chassis. These chassis support large form factor (LFF) drives or small form factor (SFF) drives in 2U12, 2U24 and 5U84 chassis. These chassis form factors support RAID chassis and expansion chassis.

Chassis User Interfaces

The QXS G2 systems support applications for configuring, monitoring, and managing the storage system. The web-based application GUI and the command-line interface are briefly described:

• The disk management utility is the web interface for the chassis, providing access to all common management functions for virtual storage.

Refer to the

QXS G2 Disk Management Utility User Guide

for additional information.

About This Guide ix

• The command-line interface (CLI) enables you to interact with the storage system using command syntax entered via the keyboard or scripting.

Refer to the

QXS G2 CLI Reference Guide

CNC Ports Used for Host Connection

QXS G2 systems that use CNC technology allow you to select the desired host interface protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the system.

NOTE: Refer to SFP Option for CNC Ports for additional information.

You can use the CLI to set all controller host ports to use either FC or iSCSI protocol using the set

host-port-mode

• 16Gb FC

• 8Gb FC

• 10GbE iSCSI

• 1GbE iSCSI

Alternatively, for QXS G2 systems you can use the CLI to set CNC ports to support a combination of host interface protocols. When configuring a combination of host interface protocols, host ports 0 and 1 are set to FC (either both 16Gb/s or both 8Gb/s), and host ports 2 and 3 must be set to iSCSI (either both 10GbE or both 1Gb/s), provided the CNC ports use qualified SFP connectors and cables required for supporting the selected host interface protocol.

CLI command. The QXS G2 systems support the following link speeds:

for additional information.

NOTE: Refer to the

CNC controller modules ship with CNC ports initially configured for FC. When connecting CNC ports to iSCSI hosts, you must use the CLI (not the disk management utility/GUI) to specify which ports will use iSCSI. It is best to configure the ports before inserting the iSCSI SFPs into the CNC ports.

• Operation of the QXS G2 Systems

• Electrical Safety

• Rack System Safety Precautions

Chapter 1

Safe Handling of Equipment

Always follow these safety cautions when handling the QXS G2 equipment.

CAUTION: Use this equipment in a manner specified by the manufacturer: failure to do this may cancel the protection provided by the equipment.

• Permanently unplug the chassis before you move it or if you think that it has become damaged in any way.

• A safe lifting height is 20U.

• Always remove the power supply units (PSUs) to minimize weight before you move the chassis.

• Do not lift the chassis by the handles on the PSUs—they are not designed to take the weight.

CAUTION: Do not try to lift the chassis by yourself:

• Fully configured 2U12 chassis can weigh up to 32 kg (71 lb).

Safety Guidelines 1

• Fully configured 2U24 chassis can weigh up to 30 kg (66 lb).

• Fully configured 5U84 chassis can weigh up to 135kg (298 lb).

• An unpopulated chassis weighs 46 kg (101 lb).

• Use appropriate lifting methods.

• Before lifting the chassis:

• Unplug all cables and label them for reconnection.

• Remove the drives from drawers and verify the drawers are closed and firmly locked.

• Use a minimum of three people to lift the chassis using the lifting straps provided.

• Avoid lifting the chassis using the handles on any of the CRUs because they are not designed to take the weight.

• Do not lift the chassis higher than 20U. Use mechanical assistance to lift above this height.

• Observe the lifting hazard label affixed to the storage chassis.

Operation of the QXS G2 Systems

IMPORTANT:

• All systems must have the following installed:

• Two controllers in the RAID chassis or two IOMs in the expansion chassis.

• Two PSUs in all chassis.

• Five fans in the 5U84 chassis.

• All drive slots in the 2U12, 2U24, and 5U84 chassis must be filled with drives or drive blanks

• Operation of the chassis with any CRU modules missing will disrupt the airflow, and the chassis will not receive sufficient cooling.

• It is essential that all slots hold modules before the QXS G2 system is used.

Ensure to follow these operation precautions:

• Observe the module bay caution label affixed to the module being replaced.

• Replace a defective power supply unit (PSU) with a fully operational PSU within 24 hours.

Do not remove a defective PSU unless you have a replacement model of the correct type ready for insertion.

• Before removal/replacement of a PSU, disconnect supply power from the PSU to be replaced.

• Observe the hazardous voltage warning label affixed to PSUs.

2 QXS G2 Hardware Installation and Maintenance Guide

Electrical Safety

Ensure to follow these electrical precautions:

• The 2U chassis must only be operated from a power supply input voltage range of 100–240 VAC, 50–60 Hz.

• The 5U chassis must only be operated from a power supply input voltage range of 200–240 VAC, 50–60 Hz.

• Provide a suitable power source with electrical overload protection to meet the requirements in the technical specification.

• The power cord must have a safe electrical earth connection. Check the connection to earth of the chassis before you switch on the power supply.

IMPORTANT: The chassis must be grounded before applying power.

• The plug on the power supply cord is used as the main disconnect device.

• The 2U and 5U chassis are intended to operate with two PSUs.

• Observe the power-supply disconnection caution label affixed to PSUs.

CAUTION: Do not remove covers from the PSU – there is a danger of electric shock inside.

• Return the PSU to your supplier for repair.

• When bifurcated power cords (Y-leads) are used, these cords must only be connected to a supply

range of 200–240 VAC.

IMPORTANT: The RJ-45 socket on the expansion input/output modules (IOMs) is for the Ethernet connection only and must not be connected to a telecommunications network.

Rack System Safety Precautions

The following safety requirements must be considered when the chassis is mounted in a rack.

• The rack construction must be capable of supporting the total weight of the installed chassis. The design should incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.

• When loading a rack with chassis, fill the rack from the bottom up; and empty the rack from the top down.

• Always remove all CRUs to minimize weight, before loading the chassis into the rack.

• Do not try to lift the chassis by yourself.

Safety Guidelines 3

CAUTION: To avoid danger of the rack falling over, under no circumstances should more than one chassis be moved out of the cabinet at any one time.

• The system must be operated with low pressure rear exhaust installation. The back pressure created by rack doors and obstacles is not to exceed 5 pascals (0.5 mm water gauge).

• The rack design should take into consideration the maximum operating ambient temperature for the chassis, which is 35ºC (95ºF) for RAID chassis and 40ºC (104ºF) for expansion chassis.

• The rack should have a safe electrical distribution system.

• It must provide over-current protection for the chassis and must not be overloaded by the total

number of chassis installed in the rack.

• When addressing these concerns, consideration should be given to the electrical power

consumption rating shown on the nameplate.

• The electrical distribution system must provide a reliable earth connection for each chassis in the rack.

• Each PSU in each chassis has an earth leakage current of 1.0mA. The design of the electrical distribution system must take into consideration the total earth leakage current from all the PSUs in all the chassis.

• The rack will require labeling with “High Leakage Current. Earth connection essential before connecting supply.”

• The rack—when configured with the chassis—must meet the safety requirements of UL 60950-1 and IEC 60950-1.

CompactFlash

During a power loss or controller failure, data stored in cache is saved off to non-volatile memory (CompactFlash). The data is restored to cache, and then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk. The CompactFlash memory card is located at the midplane-facing end of the controller module. Do not remove the card; it is used for cache recovery only.

NOTE: In dual-controller configurations featuring one healthy partner controller, there is no need to transport failed controller cache to a replacement controller because the cache is duplicated between the controllers, provided that volume cache is set to standard on all volumes in the pool owned by the failed controller.

Supercapacitor Pack

To protect controller module cache in case of power failure, each controller chassis model is equipped with supercapacitor technology, in conjunction with CompactFlash memory, built into each controller module to provide extended cache memory backup time.

The supercapacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash, in the event of a power failure. Unwritten data in CompactFlash memory is automatically committed to disk media when power is restored. In the event of power failure, while cache is maintained by the supercapacitor pack, the Cache Status LED blinks at a rate of 1/10 second on and 9/10 second off. See also Cache Overview and Status LED Details on page 45.

Additional characteristics include:

• The chassis has a 19-inch rack mounting that enables it to be installed onto standard 19-inch racks and uses five EIA units of rack space (8.75") for a 5U84 chassis.

• At the front of the chassis two drawers can be opened and closed.

28 QXS G2 Hardware Installation and Maintenance Guide

• Each drawer provides access to 42 slots for Disk Drive in Carrier (DDIC) modules.

• DDICs are top mounted into the drawers.

• The front of the chassis also provides chassis status LEDs and drawer status/activity LEDs.

• At the rear of the chassis, access is provided to rear panel CRUs:

• Two SBB-compliant RAID controllers or expansion IOMs

•Two PSUs

• Five fan cooling modules

5U Chassis Drawers

Each chassis drawer contains 42 slots, each of which can accept a single DDIC containing a 3.5" LFF drive or a 2.5" SFF drive with an adapter. See Figure 26 on page 23 and Figure 27 on page 24.

Opening a drawer does not interrupt the functioning of the storage system, and DDICs can be hot-swapped while the chassis is in operation. However, drawers must not be left open for longer than 2 minutes, or airflow and cooling will be compromised.

IMPORTANT: During normal operation, drawers should be closed to ensure proper airflow and cooling within the chassis.

A drawer is designed to support its own weight, plus the weight of installed DDICs, when fully opened.

Safety features

The chassis safety features include:

• To reduce the possibility of toppling, only one drawer can be open at a time.

• The drawer locks into place when fully opened and extended.

• To reduce pinching hazards, two latches must be released before the drawer can be pushed back

into the drawer slot within the chassis.

Power and data are sent via three baseplanes and two sideplanes. The direct-dock SATA version of the 5U chassis has one active and one passive sideplane, and has dual power paths, but only a single data path.

Locking Drawer

Each drawer can be locked shut by turning both anti-tamper locks clockwise using a screwdriver with a Torx T20 bit. The anti-tamper locks are symmetrically placed on the left-hand and right-hand sides of the drawer bezel.

Drawer status and activity LEDs can be monitored via two Drawer LEDs panels located next to the two drawer-pull pockets located on the left-hand and right-hand side of each drawer. Figure 34 on page 30 provides the location of the drawer LEDs panel (left and right side.

NOTE: Activate the Location LED by using the disk management utility (GUI) or CLI.

Unit Identification Display

The UID is a dual seven-segment display that can be used to provide feedback to the user. Its primary function is to display a chassis unit identification number to assist users in setting and maintaining multiple chassis systems.

Thermal sensor

The thermal sensor is located on the outside of the chassis, and it sends input to the chassis (RAID controller/expansion IOM) about its external operating ambient temperature.

5U Chassis Ops Panel

The 5U84 chassis front panel has an Ops panel mounted on the left ear flange. A flexible cable connects the Ops panel to the midplane. The Ops panel is a passive component: the midplane controls the panel, and the RAID controllers or expansion IOMs control all the panel’s functions.

Logical Status LED (amber)

This LED indicates a change of status or fault from something other than the chassis management system. This may be initiated from the controller module or an external HBA. The indication is typically associated with a DDIC and LEDs at each disk position within the drawer, which help to identify the DDIC affected.

Drawer Fault LEDs (amber)

This LED indicates a disk, cable, or sideplane fault in the drawer indicated: Top (Drawer 0) or Bottom (Drawer 1).

PSUs – 2U CRU

The 2U12 and 2U24 use the same type of PSUs. AC-DC power is provided by up to two auto-ranging power PSUs with integrated axial cooling fans. The RAID controllers and expansion IOMs control fan speed.

PSU Features

The 580W PSU voltage operating range is nominally 100V–240V AC, and operates at 50–60 Hz input frequency. Figure 41 provides a representative illustration of the PSUs in a 2U chassis. PSU0 and PSU1 are installed 180 degrees as compared to each other (callouts 3 and 4).

NOTE: Controller A and Controller B are also installed 180 degrees as compared to each other (callouts 1 and 2).

Figure 41 provides an illustration of the PSU (with LEDs) for the 2U12 and 2U24 chassis. The diametric

rear orientation in Figure 41 shows the PSU aligned for insertion into the right-hand PSU slot (PSU1) located on the 2U12 or 2U24 chassis rear panel.

Figure 41 PSU 2U12/2U24 Chassis

Multiple PSUs

The 2U12 and 2U24 storage systems include two PSUs which provide redundant power control for the system so that if one PSU fails, the other maintains the power supply, and chassis operation is not affected while you replace the faulty PSU.

PSUs are hot-pluggable, and replacement should only take a few seconds to do. Replacement must be completed as soon as possible after the removal of the defective PSU to avoid a thermal exception. The replacement procedure should be completed within an absolute maximum of 2 minutes.

Operation of the chassis with any modules missing will disrupt the airflow, and the drives will not receive sufficient cooling. It is essential that all slots are fitted with PSUs prior to powering on the chassis.

PSU OK LED: Green

Fan Fail LED: Amber/blinking amber

DC Fail LED: Amber/blinking amber

AC Fail LED: Amber/blinking amber

System Airflow

The system must be operated with low pressure rear exhaust installation. Back pressure created by rack doors and obstacles is not to exceed 5 pascals (0.5mm water gauge). The cooling system provides sufficient capacity to ensure that maximum temperatures are not exceeded.

The environment in which the chassis operates must be dust-free to ensure adequate airflow.

36 QXS G2 Hardware Installation and Maintenance Guide

PSU – 5U CRU

Power is provided by two 2,214W PSUs. The PSU voltage operating range is nominally 200V–240V AC, and operates at 50–60 Hz input frequency. The dimetric rear orientation in Figure 42 shows the PSU aligned for insertion into its slot located on the chassis rear panel.

Figure 42 PSU 5U84 CRU

NOTE: If any of the PSU LEDs are illuminated amber, a module fault condition or failure has

occurred.

Dual PSUs provide redundant power for the 5U system: if one PSU fails, the other keeps the system running while you replace the faulty module. PSUs are hot-swappable. Replacement of a PSU can be performed while the chassis is running, but the procedure must be completed within two minutes of the removal of the defective module. Verify that you have a replacement PSU on hand before removing the defective module.

Fan – 5U CRU

The five fans at the rear of the chassis maintain all system components below their maximum temperature, assuming the ambient temperature is below 35ºC. Fan speed is governed by the controller modules.

Fans are hot-swappable. Replacement of a fan can be performed while the chassis is running, but the procedure must be completed within two minutes of the removal of the defective module. Verify that you have a replacement module on hand before removing the defective fan.

RAID Controller and Expansion IOMs

This section describes the RAID controllers and expansion IOMs used in QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 systems. They are mechanically and electrically compliant to the latest SBB v2.1 specification.

The diametric rear orientation in Figure 44 shows a 4-port FC/iSCSI controller module aligned for use in the top controller module slot located on the 2U chassis rear panel. The controller module is also properly aligned for use in either controller slot located on the 5U chassis rear panel.

Figure 44 provides an illustration of the CNC controller (FC/iSCSI) for the 2U12, 2U24, and 5U84

chassis.

Figure 44 CNC Controller CRU

Each controller module maintains VPD (Vital Product Data) in EEPROM devices, and are interconnected by SBB-defined I2C buses on the midplane. In this way, the SBB modules can discover the type and capabilities of the partner SBB module(s), and vice versa, within the chassis. A system alarm occurs when incompatible configurations are detected.

12Gb/s Controller LEDs

The diagrams with tables that immediately follow provide descriptions for the different controller modules that can be installed into the rear panel of a RAID chassis. Showing controller modules separately from the chassis enables improved clarity in identifying the component items called out in the diagrams and described in the companion tables within the figure/table ensembles.

NOTE: Consider the following when viewing RAID controller or expansion IOM diagrams appearing on the following pages:

• In each diagram, the canister is oriented for insertion into the top controller/IOM slot (A) of 2U chassis.

• When oriented for use in the bottom controller/IOM slot (B) of 2U chassis, the controller/IOM labels appear upside down.

• In each diagram, the canister is oriented for insertion into either controller/IOM slot of 5U84 chassis.

Cache Overview and Status LED Details

This section provides the following information:

• Cache Overview

• Power On/Off Behavior

• Cache Status Behavior

Cache Overview

To enable faster data access from disk storage, the following types of caching are performed:

• Write-back caching.

• The controller writes user data into the cache memory in the controller module rather than

directly to the disks.

• Later, when the storage system is either idle or aging —and continuing to receive new I/O

data—the controller writes the data to the disks.

• Read-ahead caching.

• The controller detects sequential data access, reads ahead into the next sequence of

data—based upon settings—and stores the data in the read-ahead cache.

• Then, if the next read access is for cached data, the controller immediately loads the data into

the system memory, avoiding the latency of a disk access.

TIP: See the and settings.

QXS G2 Disk Management Utility User Guide

Power On/Off Behavior

The storage chassis unified complex programmable logic device (CPLD) provides integrated Power Reset Management (PRM) functions. During power on, discrete sequencing for power on display states of internal components is reflected by blinking patterns displayed by the Cache Status LED.

NOTE: Once the chassis has completed the power on sequence, the Cache Status LED displays Solid/On (Normal), before assuming the operating state for cache purposes.

Cache Status Behavior

If the LED is blinking evenly, a cache flush is in progress. When a controller module loses power and write cache is dirty (contains data that has not been written to drives), the supercapacitor pack provides backup power to flush (copy) data from write cache to CompactFlash memory. When cache flush is complete, the cache transitions into self-refresh mode.

If the LED is blinking momentarily slowly, the cache is in a self-refresh mode. In self-refresh mode, if primary power is restored before the backup power is depleted (3–30 minutes, depending on various factors), the system boots, finds data preserved in cache, and writes it to drives. This means the system can be operational within 30 seconds, and before the typical host I/O time-out of 60 seconds, at which point system failure would cause host-application failure. If primary power is restored after the backup power is depleted, the system boots and restores data to cache from CompactFlash, which can take about 90 seconds.

The cache flush and self-refresh mechanism is an important data protection feature; essentially four copies of user data are preserved: one in controller cache and one in CompactFlash of each controller. The Cache Status LED illuminates solid green during the boot-up process. This behavior indicates the cache is logging all POSTs, which will be flushed to the CompactFlash the next time the controller shuts down.

IMPORTANT: If the Cache Status LED illuminates solid green—and you wish to shut down the controller—do so from the user interface, so unwritten data can be flushed to CompactFlash.

Controller Failure/Single-Controller Operational

Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write to CompactFlash process, only the components needed to write the cache to the CompactFlash are powered by the supercapacitor.

This process typically takes 60 seconds per 1Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the supercapacitor is used to refresh the cache memory. While the cache is being maintained by the supercapacitor, the Cache Status LED blinks at a rate of 1/10 second on and 9/10 second off.

Drive Carrier Module in 2U Chassis

The drive carrier module comprises a hard disk held by a carrier.

• Each 2U12 drive slot holds a single low profile 1.0-inch high, 3.5-inch form factor drive in its carrier.

• The drives are horizontal.

• The 2U12 chassis accommodates 3.5” SAS and 3.5” SATA drives.

• A special interposer is required for SATA drives (included with the SATA drive and its carrier

when purchased).

• Each 2U24 drive slot holds a single low profile 5/8-inch high, 2.5-inch form factor disk drive in its carrier.

• The drives are vertical.

• The 2U24 chassis accommodates 2.5” SAS or SATA drives.

• A special interposer is required for SATA drives (included with the SATA drive and its carrier

when purchased).

The carriers have mounting locations for:

• Direct dock SAS drives.

• A sheet steel carrier holds each drive, which provides thermal conduction, radio frequency, and

electro-magnetic induction protection, and physically protects the drive.

The front cap also has an ergonomic handle which gives the following functions:

• Secure location of the carrier into and out of drive slots.

• Positive spring-loading of the drive/midplane connector.

• The carrier can use this interface:

• Dual path direct dock Serial Attached SCSI.

Populating 2U12 Chassis with Drives

The 2U12 chassis ships with drives installed. Please review these rules:

• The minimum number of drives supported by the chassis is 1.

• Hard disk drives (HDD) and solid state drives (SDD) can be mixed in the chassis.

NOTE: If the chassis has no drives installed, always install the first drive into slot 0, and then

populate slots 1-11 sequentially with any additional drives.

Integers on the drives indicate drive slot numbering sequence (0-11). Figure 50 provides a front view of the 2U12-drive chassis fully populated with drives.

Populating Drawers with DDICs

The 5U84 chassis does not ship with DDICs installed. Please review these rules:

• The minimum number of drives supported by the chassis is 14.

• DDICs must be added to drive slots in rows (14 drives at a time).

• Beginning at the front of the drawer(s), install DDICs consecutively by number, and alternately

between the top drawer and the bottom drawer.

• Namely, install first at slots 0 through 13 in the top drawer, and then 42 through 55 in the

bottom drawer.

• After that, install slots 14 through 27, and so on.

• The number of populated rows must not differ by more than one row between the top and bottom drawers.

• Hard disk drives (HDD) and solid state drives (SDD) can be mixed in the same drawer.

• HDDs installed in the same row should have the same rotational speed.

• Although DDICs holding 3.5" disks can be intermixed with DDICs holding 2.5" disks within the

chassis, each row should be populated with drives of the same form factor (all LFF or all SFF).

NOTE: For additional information, see Populating 5U84 Drawers on page 195 within 5U84 Chassis

CRU Replacement on page 190.

Figure 57 shows a 5U84 chassis drawer fully populated with DDICs (42 drives).

Chassis Management

Controller modules actively manage the chassis. Each controller has a SAS expander with its own storage enclosure processor (SEP) that provides a SES target for a host to interface to through the ANSI SES Standard. If one of these controllers fails, the other module will continue to operate.

Refer to the controller’s specification or the SES Interface specification for definitions of the module’s functions and its SES control.

System Overview 53

Management Interfaces

Upon completing the hardware installation, you can access the controller module’s web-based management interface—disk management utility (GUI)—to configure, monitor, and manage the storage system. See also “Accessing the disk management utility”.

The controller module also provides a CLI in support of command entry and scripting.

(RAID chassis).

Expansion IOM Rear panel Two expansion IOMs must be installed for this configuration

(expansion chassis).

NOTE: Although different drive modules and rear panel CRUs are used by the different chassis form factors, whether used for RAID chassis or expansion chassis configuration, the RAID controllers and expansion IOMs are common across 2U and 5U chassis.

Preparing for Installation

NOTE: Chassis configurations:

• 2U RAID chassis are delivered without drives installed (RAID controllers and PSUs are installed).

• 2U expansion chassis are delivered without drives installed (expansion IOMs and PSUs are

installed).

• 5U RAID chassis are delivered:

• Without drives installed within the drawers.

• Drives ship in a 42-drive pack (two each 42-drive packs for a total of 84 drives).

• RAID controllers, fans, and PSUs are installed within the chassis.

• 5U expansion chassis are delivered:

• Without drives installed in the drawers.

• Drives ship in a 42-drive pack (two each 42-drive packs for a total of 84 drives).

• Expansion IOMs, fans, and PSUs are installed within the chassis.

CAUTION: Lifting chassis:

• A 2U chassis—together with all its component parts—is too heavy for one person to lift and install

into the rack cabinet. Two people are required to safely move a 2U chassis.

• A 5U chassis—delivered without DDICs installed—requires four people to lift it from the box. A suitable mechanical lift is required to hoist the chassis for positioning in the rack.

Make sure you wear an effective anti-static wrist or ankle strap and obey conventional ESD precautions when touching modules and components. Do not touch midplane, motherboard, or module connectors. See also ESD Precautions on page 165. This section provides important preparation requirements and handling procedures for use during product installation.

Installation 61

Requirements for rackmount installation

You can install the chassis in an industry standard 19-inch cabinet capable of holding 2U form factors.

• Minimum depth: 707 mm (27.83") from rack posts to maximum extremity of chassis (includes rear panel cabling and cable bend radii).

• Weight:

• Up to 32 kg (71 lb), dependent upon configuration, per 2U chassis.

• Up to 128 kg (282 lb), dependent upon configuration, per 5U chassis.

• The rack should cause a maximum back pressure of 5 pascals (0.5 mm water gauge).

• Before you begin, ensure that you have adequate clearance in front of the rack for installing the

rails.

Rackmount rail kit

Various sets of rack mounting rails are available for use in 19-inch rack cabinets. These rails have been designed and tested for the maximum chassis weight, and to make sure that multiple chassis may be installed without loss of space within the rack. Use of other mounting hardware may cause some loss of rack space. Contact your supplier to make sure suitable mounting rails are available for the rack you plan to use.

Installing 2U Chassis

Install the chassis as follows:

1 Remove the rack mounting rail kit from the accessories box, and examine for damage.

2 Use the following procedure to attach the rail kit brackets to the rack post as shown in Figure 60.

a Set the location pin at the rear of the rail into a rear rack post hole.

• Attach the bracket to the rear rack post: use the washers and screws supplied (callout 9, A screw).

• Leave the screws loose.

b Extend the rail to fit between the front and rear rack posts.

c Attach the bracket to the front rack post using the washers and screws supplied (callout 3,

A screw). Leave the screws loose.

Installation 63

Installing 5U Chassis

The 5U84 chassis is delivered without the disks installed. Due to the weight of the chassis, install the chassis into the rack without DDICs installed, and remove the rear panel CRUs to lighten the chassis weight.

The adjustment range of the rail kit from the inside of the front post to the inside of the rear post is 660mm – 840mm(64”-xx”). This range suits a one meter deep rack within Rack Specification IEC

60297.

Install the chassis as follows:

1 To facilitate access, remove the doors from the cabinet.

2 Ensure that the pre-assembled rails are at their shortest length (refer to the reference label on the

inside of the rail).

3 Locate/seat the rail location pins (callout 5) inside the front of the rack, and extend the length of

the rail assembly to enable the rear location pins to locate/insert into the back of the rack (callout

Full Disk Encryption (FDE)

The Full Disk Encryption (FDE) feature available via the management interfaces requires use of self-encrypting drives (SED) which are also referred to as FDE-capable drive modules. When installing FDE-capable drive modules, follow the same procedures for installing drives that do not support FDE.

The procedures for using the FDE feature, such as securing the system, viewing drive FDE status, and clearing and importing keys are performed using the disk management utility (GUI) or CLI commands.

Installation 65

NOTE: When moving FDE-capable drive modules for a disk group, stop I/O to any volumes in the disk group before removing the drive modules.

Follow the procedures in “Module removal and replacement” for replacing drive modules relative to the chassis type (2U or 5U). Import the keys for the drives so that the drive content becomes available.

Federal Information Processing Standards (FIPS)

FIPS are U.S. government computer security standards that specify requirements for cryptography modules. FIPS is a widely recognized and demanded cert when it comes to government agencies and industry’s subject to strict security compliance. FIPS certification is available on self-encrypting drives (SEDs).

Connecting RAID Chassis and Expansion Chassis

Use this section to connect the RAID chassis to the expansion chassis. Connecting/cabling suggestions are provided. The customer can select the applicable connecting/cabling best suited for their installation.

NOTE: Reverse cabling/straight-through cabling for the RAID chassis and expansion is provided. Reverse cabling is suggested because it provides redundancy (alternate path to access chassis).

The chassis support both straight-through and reverse SAS cabling. Reverse cabling allows any drive chassis to fail—or be removed—while maintaining access to other chassis. Fault tolerance and

66 QXS G2 Hardware Installation and Maintenance Guide

performance requirements determine whether to optimize the configuration for high availability or high performance when cabling.

Cabling diagrams in this section show fault-tolerant cabling patterns. RAID controller and expansion IOMs are identified by chassis ID and IOM ID, such as 0A and 0B for controllers (RAID chassis), 1A and 1B for the first expansion chassis IOMs in a cascade, and so forth. When connecting multiple expansion chassis, use reverse cabling to ensure the highest level of fault tolerance, enabling controllers to access remaining expansion chassis if an expansion chassis fails.

Cable Requirements for Expansion Chassis

When adding storage, use only Quantum or OEM-qualified cables, and observe the following guidelines:

• When installing SAS cables to expansion IOMs, use only supported HD mini-SAS x4 cables.

• Qualified HD mini-SAS to HD mini-SAS 0.5 m (1.64') cables are used to connect cascaded chassis in

the rack.

• The maximum expansion cable length allowed in any configuration is 2 m (6.56').

• When adding more than two expansion chassis, you may need to purchase additional cables,

depending upon number of RAID chassis, expansion chassis, and cabling method used.

• You may need to order additional or longer cables when reverse-cabling a fault-tolerant configuration.

The rear panel view of the 2U12 and 2U24 RAID chassis are identical to one another. The rear panel views of the expansion chassis are also identical to one another.

Whether configured as a RAID chassis or expansion chassis, the rear panel view of the 5U84 is very different than the 2U12 or 2U24. Although the 5U84 uses the same controllers and expansion IOMs used in the 2U chassis, the remaining CRUs accessible from the chassis rear panel differ from those used in the 2U chassis.

NOTE: For clarity, the schematic diagrams show only relevant details such as the controller and expansion IOM face plate outlines and expansion ports.

Figure 62 Reverse Cabling/Straight-through Cabling

Figure 62 (left) shows reverse cabling of a RAID chassis dual-controller 2U chassis and supported 2U

drive chassis configured with dual expansion IOMs. Controller module 0A is connected to expansion module 1A, with a chain of connections cascading down (blue). Controller module 0B is connected to the lower expansion module (9B), of the last expansion chassis, with connections moving in the opposite direction (green). Reverse cabling allows any expansion chassis to fail—or be removed—while maintaining access to other chassis.

The diagram at right (above) shows the same storage components connected to use straight-through cabling. Using this method, if an expansion chassis fails, the chassis that follow the failed chassis in the chain are no longer accessible until the failed chassis is repaired or replaced.

The 2U expansion chassis shown in Figure 62 can either be of the same type or they can be a mixture of the 2U12 and 2U24 models. Given that supported expansion chassis models use 12Gb/s SAS link-rate and SAS 3.0 expanders, they can be ordered in desired sequence within the system, following the RAID chassis. The middle SAS ports (Port B) on expansion modules are not used. Refer to Expansion Chassis IOM on page 19 for additional information.

Figure 68 provides an illustration of connecting 5U RAID chassis PSUs to an AC PDU.

Figure 68 Connecting 5U RAID chassis PSUs to AC PDU

IMPORTANT: When more than one PSU is fitted, all power cords must be connected to at least two

separate and independent power supplies to ensure redundancy. When the storage system is ready for operation, ensure that each PSU power switch is set to the On position.

CAUTION: Power connection concerns:

• Always remove the power connections before you remove the PSU from the chassis.

• When bifurcated power cords (Y leads) are used, these cords must only be connected to a supply

range of 200–240V AC.

Installation 71

Testing Chassis Connections

See Powering On/Powering Off on page 105. Once the power-on sequence succeeds, the storage system is ready to be connected as described in Host Connection on page 76.

Grounding Checks

The product must only be connected to a power source that has a safety electrical earth connection.

CAUTION: If more than one chassis goes into a rack, the importance of the earth connection to the rack increases because the rack will have a larger Earth Leakage Current (Touch Current).

Examine the earth connection to the rack before power on. An electrical engineer who is qualified to the appropriate local and national standards must do the examination.

Host System Requirements

NOTE: Refer to the QXS-G2 (12G) Quantum Interoperability and Certification Matrix for Quantum

model numbers, firmware release, firmware required for host systems, RAID hardware certifications, and HBA attach.

Hosts connected to QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 systems must meet the following requirements:

• Depending on your system configuration, host operating systems may require that multipathing is supported.

• If fault tolerance is required, then multipathing software may be required.

• Host-based multipath software should be used in any configuration where two logical paths

between the host and any storage volume may exist at the same time.

• This would include most configurations where there are multiple connections to the host or

multiple connections between a switch and the storage.

• Use native Microsoft MPIO DSM support with Windows Server 2008, Windows Server 2012, and Windows Server 2016. Use either the Server Manager or the

Cabling Considerations

mpclaim CLI tool to perform the installation.

Common cabling configurations address hosts, RAID chassis, expansion chassis, and switches. Host interface ports on the QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis can connect to respective hosts via direct-attach or switch-attach. Cabling systems to enable use of the optional replication feature—to replicate volumes—is yet another important cabling consideration. See Connecting Management Host to Network on page 83. The FC and iSCSI product models can be licensed to support replication.

72 QXS G2 Hardware Installation and Maintenance Guide

Use only QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 system or OEM-qualified cables to connect host to RAID chassis:

• Qualified Fibre Channel SFP and cable options

• Qualified 10GbE iSCSI SFP and cable options

• Qualified 1Gb RJ-45 SFP and cable options

A host identifies an external port to which the storage system is attached. The external port may be a port in an I/O adapter (such as an FC HBA) in a server. Cable connections vary depending on configuration. This section describes host interface protocols supported by QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis, while showing a few common cabling configurations.

NOTE: QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 controllers use Unified LUN Presentation (ULP), which enables a host to access mapped volumes through any controller host port.

ULP can show all LUNs through all host ports on both controllers, and the interconnect information is managed by the controller firmware. ULP appears to the host as an active-active storage system, allowing the host to select any available path to access the LUN, regardless of disk group ownership.

TIP: See the topic about configuring system settings in the

Guide

to initially configure the system, or change system configuration settings (such as Configuring

host ports).

CNC Technology

The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 FC/iSCSI models use Converged Network Controller (CNC) technology, allowing you to select the desired host interface protocol(s) from the available FC or iSCSI host interface protocols supported by the system. The small form-factor pluggable (SFP transceiver or SFP) connectors used in CNC ports are further described in the subsections below.

Refer to the following for additional CNC information:

• QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID Chassis Rear View (4-Host Port Controllers) on

page 18

• QXS-G2-312 and QXS-G2-324 RAID Chassis Rear View (2-Host Port Controllers) on page 16

• 5U84 RAID Chassis (Rear View/Two CNC Controllers) on page 24

NOTE: Controller modules are shipped with SFPs installed (FC or iSCSI per customer order).

QXS G2 Disk Management Utility User

CAUTION: Use the set host-port-mode CLI command to set the host interface protocol for CNC ports using qualified SFP options (if required).

• QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 models ship with CNC ports configured for FC or iSCSI per customer order.

• Using FC or iSCSI SFPs in combination is not supported currently.

Installation 73

• If the customer changes SFPs, you must use the CLI (not the disk management utility, GUI) to specify which ports will use FC or iSCSI.

• It is best to do this before inserting the SFPs into the CNC ports (see Change CNC Port Mode on page 98 for instructions).

Fibre Channel (FC) Protocol

NOTE: A FC protocol connectivity kit must be purchased from Quantum; it contains qualified SFPs

and cables to support the FC protocol.

The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis support two controller modules using the Fibre Channel interface protocol for host connection.

• The QXS-G2-312 and QXS-G2-324 FC controller module provides two host ports.

• The QXS-G2-412, QXS-G2-424, and QXS-G2-484 FC controller module provides four host ports.

• CNC ports are designed for use with an FC SFP supporting data rates up to 16Gb/s.

The controllers support Fibre Channel Arbitrated Loop (public or private) or point-to-point topologies. Loop protocol can be used in a physical loop or for direct connection between two devices. Point-to-point protocol is used to connect to a fabric switch. Point-to-point protocol can also be used for direct connection, and it is the only option supporting direct connection at 16Gb/s.

See the syntax and details about parameter settings relative to supported link speeds. Fibre Channel ports are used for attachment to FC hosts directly, or through a switch used for the FC traffic. The host computer must support FC and optionally, multipath I/O.

The Fibre Channel ports are used in either of two capacities:

• To connect two storage systems through a switch for use of replication.

• For attachment to FC hosts directly, or through a switch used for the FC traffic.

The first usage option requires valid licensing for the replication feature, whereas the second option requires that the host computer supports Ethernet, FC, and optionally, multipath I/O.

Installation 75

Host Connection

The QXS-G2-312 and QXS-G2-324 RAID chassis support up to four direct-connect server connections, two per controller module.

• Use only qualified cables purchased from Quantum for all host connections.

• Connect appropriate cables from the server’s HBAs to the controller module’s host ports as

described below, and shown in the following illustrations.

The QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis support up to eight direct-connect server connections, four per controller module.

• Use only qualified cables purchased from Quantum for all host connections.

• Connect appropriate cables from the server’s HBAs to the controller module’s host ports as

described below, and shown in the following illustrations.

Fibre Channel Host Connection

To connect controller modules supporting (4/8/16Gb) FC host interface ports to a server HBA or switch, using the controller’s CNC ports, select a qualified FC SFP option.

Qualified options support cable lengths of 1 m (3.28'), 2 m (6.56'), 5 m (16.40'), 15 m (49.21'), 30 m (98.43'), and 50 m (164.04') for OM4 multimode optical cables and OM3 multimode FC cables, respectively. A 0.5 m (1.64') cable length is also supported for OM3. In addition to providing host connection, these cables are used for connecting two storage systems via a switch, to facilitate use of the optional replication feature.

10GbE iSCSI Host Connection

To connect controller modules supporting 10GbE iSCSI host interface ports to a server HBA or switch, using the controller’s CNC ports, select a qualified 10GbE SFP option.

Qualified options support cable lengths of 0.5 m (1.64'), 1 m (3.28'), 3 m (9.84'), 5 m (16.40'), and 7 m (22.97') for copper cables; and cable lengths of 0.65 m (2.13'), 1 m (3.28'), 1.2 m (3.94'), 3 m (9.84'), 5 m (16.40'), and 7 m (22.97') for direct attach copper (DAC) cables. In addition to providing host connection, these cables are used for connecting two storage systems via a switch, to facilitate use of the optional replication feature.

In addition to providing host connection, these cables are used for connecting two storage systems via a switch, to facilitate use of the optional replication feature.

Connecting Direct Attach Configurations

A dual-controller configuration improves application availability because in the event of a controller failure, the affected controller fails over to the healthy partner controller with little interruption to data flow. A failed controller can be replaced without the need to shut down the storage system. The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis are configured with dual controller modules.
