DANGER

DANGER: Hazardous voltage, current, or energy levels are present inside any component that has

this label attached. Do not open any cover or barrier that contains this label. (L001)

Do not remove covers from the enclosure or any of the modules. There is a danger of electric shock inside. Do not attempt to disassemble the rear subchassis from the enclosure. Return any damaged components to your supplier for repair.

CAUTION: The PSUs contain double pole/neutral fusing. Ensure that your electrical installation can support this type of fusing.

Rack system safety precautions

The enclosure must be mounted in a rack before use.

The rack must support the total weight of the installed enclosures. A fully populated enclosure weighs up to 135 kg (298 lb). 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 enclosures, fill the rack from the bottom up. When removing enclosures, empty from the top down.

CAUTION: The enclosure must be mounted into a rack by using the supplied rail kit only. Due to its weight and length, the enclosure must not be flange mounted.

Before mounting the enclosure, remove all DDIC modules from both drawers and make sure that the drawers are closed firmly and locked shut. Do not try to lift the enclosure by yourself (see "Handling").

CAUTION: Never move more than one enclosure out of the rack at any one time. There is a danger of the rack falling over.

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

The minimum open area for the rack doors is 70%.

The rack design should consider the maximum operating ambient temperature for the enclosure, which is 35°C.

The rack must have a safe electrical distribution system. It must provide overcurrent protection for the enclosure and must not be overloaded by the total number of enclosures that are installed in the rack. When addressing these concerns, consideration should be given to the electrical power consumption rating shown on the nameplate.

6 Slicestor

2584 Appliance Manual

The electrical distribution system must provide a reliable ground for each enclosure, and for the rack.

Each PSU in each enclosure has a ground leakage current of 1.6 mA. The design of the electrical distribution system must consider the total ground leakage current from all the PSUs in all the enclosures. The rack must be labeled with the words: “HIGH LEAKAGE CURRENT. Ground connection essential before connecting supply.”

The rack must meet the safety requirements of UL 60950-1 and IEC 60950-1.

Electrostatic discharge (ESD) precautions

Fit and check a suitable anti-static wrist or ankle strap and observe all conventional ESD precautions when handling plug-in modules and components. Avoid contact with backplane components and module connectors.

Regional safety

For North American use, the branch circuit must be rated for 20A.

This equipment is suitable for connection to an IT power system (Norway).

2584 Appliance Manual

Chapter 2. System overview

Chassis

The system is housed in a 5U chassis that contains two drawers of 42 drives each (84 drives in total).

The system is shown in the following figures.

Figure 7. Enclosure front view

The system uses 3.5” SATA drives. Each drive is hot pluggable and can be replaced on site.

The enclosure core product

The Slicestor®design concept is based on an enclosure subsystem together with a set of plug-in modules.

A typical enclosure system for direct dock SATA (as supplied) comprises: v The enclosure chassis has the following parts.

– Two sliding drawers containing Disk Drive In Carrier (DDIC) modules – An operator’s (ops) panel – A front bezel – A midplane PCB into which other components connect

v Two Power Supply Units (PSUs). The system can be operated on a single PSU. v One PSU module blank. v Five cooling modules.

v One compute module. Must be inserted in slot B (RHS). v One compute module blank. v Up to 84 Disk Drive In Carrier (DDIC) modules with SATA drives installed. v A rail kit for rack mounting.

Important: To ensure correct airflow and cooling, all PSU bays and cooling module bays must contain a functioning unit.

Figure 8. AP-TL-1 module locations

Figure 9. AP-LS-1 module locations

Components

The chassis consists of a sheet metal enclosure assembly with an integrated midplane PCB, module runner system, and two drawers for drive modules.

10 Slicestor

2584 Appliance Manual

The chassis has a 19-inch rack mounting that enables it to be installed on to standard 19-inch racks and uses 5 EIA units of rack space (8.75 inches (222 mm)).

Each drawer contains 42 bays for Disk Drives in Carriers (DDICs). DDICs are top-mounted into the drawers.

At the rear, the chassis assembly can accept two PSUs (or one PSU + one PSU blank), one SBB compute module and SBB module blank, and five cooling modules.

Drawers

Each drawer contains 42 slots, each of which accepts a single DDIC containing a 3.5” drive.

Opening a drawer does not interrupt the functioning of the system, and DDICs can be hotswapped while the enclosure continues to operate. However, drawers must not be left open for longer than 2 minutes, otherwise airflow and cooling are compromised.

The drawer is designed to support its own weight, plus the weight of any drives, when fully open.

The following safety features are included:

v To reduce the possibility of toppling, only one drawer can be open at any one time. v The drawer locks into place when opened all the way. To reduce pinching hazards, two latches must be

released before the drawer can be pushed back in.

Data is sent via three baseplanes and a single sideplane that is mounted on the left side of the drawer, with no redundant path available. Power is sent via three baseplanes and two sideplanes, the sideplanes ensures a redundant power path to each drive. The right sidpelane provides power to the drives and does not provide a data path.

Each drawer is locked shut by turning both anti-tamper locks clockwise. Use a screwdriver with a Torx T20 bit (see Figure 8 on page 10). Each side of each drawer has a series of status LEDs, shown in the following figure.

Chapter 2. System overview 11

Figure 10. Drawer LEDs (left side only)

Important: During normal operation, drawers must be kept shut to ensure correct airflow and cooling.

Disk drives in carriers (DDICs)

Each drive is housed in a carrier that enables secure insertion of the drive into the drawer and contains a SAS carrier transition card (used with direct dock SATA).

Figure 11. A disk drive in carrier (DDIC)

12 Slicestor

2584 Appliance Manual

The following hard disk drives are supported: v 3.5” 7200 rpm SATA drive

The drive carrier has a single amber LED that is lit when the drive has a fault.

Chapter 2. System overview 13

Operator’s panel

Figure 12. Enclosure operator’s panel

The left front of the enclosure features an operator’s (ops) panel (shown in previous figure). The panel contains the following indicators:

Unit Identification Display

A numerical display whose primary function is to display the enclosure unit identification number. It can be helpful when setting up and maintaining multiple enclosure systems.

However, a VPD (Vital Product Data) option allows the unit identification display to be configured for other purposes. The display is on by default and displays a value of 0. See "Unit Identification Number".

Mute/Input button

Used to set the unit identification display. See "How To Set the Unit Identification Number".

Power On/Standby LED (green/amber)

Shows amber when the system is in standby (not operational). Shows green when the system is on (operational).

Module Fault LED (amber)

Shows amber when a system hardware fault exists. Additionally, an LED might be lit on a PSU, drawer, DDIC, cooling module, or compute module that helps you identify which component is at fault.

Logical Status LED (amber)

Indicates a change of status or fault from something other than the Enclosure Management (EM) system. It is usually associated with a disk drive and LEDs at each disk drive position help you identify the drive that is affected.

Drawer 1 Fault LED (amber)

Indicates a drive, cable, or sideplane fault in drawer 1.

Drawer 2 Fault LED (amber)

Indicates a drive, cable, or sideplane fault in drawer 2.

The ops panel is a part of the chassis, and is not replaceable on site.

Power supply unit (2200 kW PSU)

Power is provided by two 2200 W PSUs. These units require an input of 200 to 240 VAC at 50 to 60 Hz.

14 Slicestor

2584 Appliance Manual

The following figure shows the PSU.

Figure 13. 2200 W PSU

Dual PSUs provide redundant power for the system. If one PSU fails, the other keeps the system running while you replace the faulty module. The PSUs are hot-swappable. Replacement of a PSU can be performed while the enclosure is running, but the procedure must be completed within 2 minutes of the removal of the defective PSU. Ensure that you have a replacement PSU before you remove the defective PSU.

The enclosure chassis is keyed to prevent PSUs from being inserted upside down.

The back of the PSU has a power switch, three status LEDs, and a socket for the power cord, as shown in the following figure.

Figure 14. PSU LEDs

Power supply unit (2800 kW PSU)

Chapter 2. System overview 15

The following figure shows the PSU.

Figure 15. 2800 W PSU

The enclosure chassis is keyed to prevent PSUs from being inserted upside down.

The back of the PSU has a power switch, three status LEDs, and a socket for the power cord, as shown in the following figure.

Figure 16. PSU LEDs

Cooling module

The five cooling modules at the rear of the enclosure maintain all system components below their maximum temperature, assuming the ambient temperature is below 95° F (35°C).

16 Slicestor

2584 Appliance Manual

The speed of the fans in the cooling modules is controlled by the SSB compute modules. For more information about the system airflow, see “System airflow.”

Cooling modules can be hot-swapped while the enclosure is still running, assuming that only one module is removed at a time and the swap takes no longer than 2 minutes. Ensure that you have a replacement cooling module before you remove the defective cooling module.

The following figure shows a cooling module.

Figure 17. Cooling module

System airflow

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

The minimum open area for the rack doors is 70%.

Cooling module LEDs

Cooling modules have LEDs for the module status and fan faults.

The following figure shows the LEDs for a cooling module.

3. Remove the packaging, as shown in the following figure.

Figure 21. Unpacking the system

Installation

First, install the rail kit, then install the modules.

Installing the rail kit

CAUTION: An unpopulated enclosure can weigh up to 46 kg (101 lb). Do not try to lift it by yourself.

Due to the weight of the enclosure, install it without the drive carriers.

The adjustment range of the rail kit, from the inside of the front post to the inside of the rear post is 660 mm - 840 mm. It suits a 1-meter deep rack within Rack Specification IEC 60297.

1. To facilitate access, remove the door from the rack.

2. Ensure that the pre-assembled rails are at their shortest length.

3. Locate the rail location pins inside the front of the rack and extend the length of the rail assembly to

enable the rear location pins to locate. Ensure that the pins are fully located in the square or round

22 Slicestor

holes in the rack posts, as shown in the following figure.

Figure 22. Mounting the system into a rack (left rail only)

4. Fully tighten all clamping screws and middle slide locking screws.

5. Ensure the rear spacer clips (x4) are fitted tight to the edge of the rack post.

6. Slide the enclosure fully home on its rails.

7. Fasten the front of the enclosure by using the enclosure fastening screws (x4).

8. Fix the rear of the enclosure to the hold-down bracket with the rear enclosure fixing screws (x2).

Note: Use the long or short hold-down bracket depending on the distance from the rack post to the enclosure hold-down slot. Ensure that the sliding nut is at the rear of the slot before fitting the bracket to the post. Then, slide the nut along the slot to enable the rear enclosure fastening screw to be fitted.

Note: For rack depths where the rack posts are behind the enclosure hold-down slots:

1. Swap the left and right hold-down brackets.

2. Insert the long flange between the rack post and chassis side, as shown in the following figure.

Chapter 3. Installation 23

Figure 23. Rear enclosure mounting

3. The sliding nut head must always face away from the enclosure, whichever configuration is used.

CAUTION: Use only the power cords that are supplied or cords that match the specification in Appendix B, "AC power cords".

CAUTION: After the enclosure is installed in the rack, dispose of the lifting straps. Due to the difficulty in attaching the straps after the enclosure is installed in the rack, the straps are not suitable for removing the enclosure from the rack.

Inserting modules

See the "Module replacement" chapter for the following instructions:

v "Inserting a cooling module" v "Inserting a PSU" v "Inserting an SBB compute module" v "Inserting a DDIC"

Power cord connection

Observe all warnings that are related to power cords.

Important: When more than one PSU is fitted, connect each PSU to separate and independent supplies to assure redundancy.

CAUTION: Always remove the power connections before you remove the PSU from the enclosure.

Grounding checks

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

CAUTION: If one or more 5U enclosures go into a rack, the importance of the ground connection to the rack increases because the rack has a larger "EARTH LEAKAGE CURRENT" ("TOUCH CURRENT").

Examine the ground connection to the rack before turning it on. An electrical engineer who is qualified for the appropriate local and national standards must do the examination.

2584 Appliance Manual

For more information, see "Electrical safety".

Data security

Precautions can help preserve data security.

v Power down your host computer and all attached peripheral devices before beginning installation. v Each enclosure contains up to 84 removable disk drive modules. Disk drives are fragile. Handle them

with care, and keep them away from strong magnetic fields.

v All the supplied plug-in modules must be in place for the air to flow correctly around the enclosure

and also to complete the internal circuitry.

v If the enclosure system is used with missing modules for more than a few minutes, the enclosure can

overheat, causing power failure and data loss. Such use can also invalidate the warranty.

v If you remove a drive module, replace it immediately. If it is faulty, replace it with a drive module of

the same type and capacity.

v Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move

the rack installation.

v Do not abandon your backup routines.

Unit identification number

After a unit identification number is set, it is stored in the midplane VPD by the Enclosure Management software and appears when the enclosure is next powered on.

How to set the unit identification number

The unit identification number is not set before the first system power-on. The display is set to “00” (flashing). The enclosure continues to power on even if the unit identification number is not set.

To set the unit identification number, do the following steps.

1. Press and hold the Input switch on the ops panel for 5 seconds. The left digit flashes.

2. Press and release the Input switch to increment the number until the wanted digit is reached.

3. Press and hold the Input switch for 5 seconds. The right digit flashes.

4. Press and release the Input switch to increment the number until the wanted digit is reached.

5. Press and hold the Input switch for 5 seconds to finish setting the number. Values of “01” to “99” are

valid.

In a situation where the VPD cannot be read, or where there is no enclosure management (compute module management failure) the enclosure displays “00”.

Other uses

The unit identification number can also have the following uses:

v Error codes. v Unit location identifier. This function sets the display to flash (3 seconds on, 1 second off) until it is

stopped, either through SES or by pressing the Input switch.

Chapter 4. Operation 29

The unit identification number can be set via other methods. Contact your storage vendor for details. As previously stated, the new setting is applied only after a power cycle. All other functions remain the same as described.

Power down

Shut down the system from within the operating system and then turn off all installed PSUs by moving the power switches to the “Off” position.

Lock the drawers

A drawer can be locked shut by using a screwdriver with a Torx T20 bit to rotate both anti-tamper locks until the red arrows point away from the center of the enclosure.

Thermal monitoring and control

The system uses extensive thermal monitoring and takes a number of actions to ensure that component temperatures are kept low and also to minimize acoustic noise. Air flows from the front to the rear of the enclosure.

Symptom

If the ambient air is below 77 °F (25 °C) and the fans are observed to increase in speed, then some restriction on airflow might be causing internal temperature rise.

Note: It is not a fault condition.

Cause The first stage in the thermal control process is for the fans to automatically increase in speed

when a thermal threshold is reached. It can be caused by higher ambient temperatures in the local environment and can be perfectly normal.

Note: This threshold changes according to the number of drives and power supplies fitted.

Action

1. Check the installation for any airflow restrictions at either the front or rear of the enclosure. A

minimum gap of 25 mm at the front and 50 mm at the rear is needed.

2. Check for restrictions due to dust buildup. Clean.

3. Check for excessive recirculation of heated air from rear to the front. Use of the enclosure in a

fully enclosed rack is not ideal.

4. Check that all blank modules are in place.

5. Reduce the ambient temperature.

Thermal alarm

Symptom

Ops panel module fault LED is amber.

Cause The internal temperature exceeded a preset threshold. Action

1. Check that the local ambient environment temperature is below the specification (see

“Temperature and humidity” on page 51).

38 Slicestor

2584 Appliance Manual

2. Check the installation for any airflow restrictions at either the front or rear of the enclosure. A

minimum gap of 1 in. (25 mm) at the front and 2 in. (50 mm) at the rear is recommended.

3. Check for restrictions due to dust buildup. Clean.

4. Check for excessive recirculation of heated air from rear to the front. Use of the enclosure in a

fully enclosed rack is not recommended.

5. If possible, shut down the enclosure and investigate the problem.

Hardware faults

Ensure that you obtained a replacement module of the same type before removing any faulty module.

Important: If the enclosure is powered on and you remove a module, replace it immediately. If the system is used with any modules that are missing for more than a few seconds, the enclosure can overheat, causing power failure and data loss. Such action invalidates the warranty.

Important: Observe all conventional ESD precautions when handling modules and components. Avoid contact with midplane components and module connectors.

Chapter 5. Troubleshooting 39

40 Slicestor

2584 Appliance Manual

Chapter 6. Module replacement

Overview

Observe all precautions when replacing modules.

Important: Always have available a replacement or blank module before removing the old module. When you replace a module, you must never leave an empty bay in the rear of the enclosure.

ESD Precautions

Important: Fit and check a suitable anti-static wrist or ankle strap and observe all conventional ESD precautions when handling plug-in modules and components. Avoid contact with midplane and sideplane components, and with module connectors.

Continuous operation during replacement

Your hardware or software enclosure management application determines the capability of replacing a failed disk without loss of access to any file system on the enclosure. Enclosure access and use during this period is uninterrupted. If an enclosure contains two PSUs, one of them can maintain power to the system while the other is replaced.

Field replaceable units (FRUs)

Please refer to the IBM Field Replaceable Units Reference Guide for more information.

The IBM Cloud Object Storage System™Slicestor®2584 does not feature hot swap sideplanes.
