Safety precaution

Read these instructions carefully before you install, operate, or transport the Infortrend storage systems and expansion systems.

Energy hazards precaution

This equipment is intended to be used in a restricted access location, like a computer room. Only allow access to SERVICE PERSONS or users who have been instructed about the metal chassis of the

equipment, which may have hazardous energy that service persons must pay attention or take special

protection before touching it. Also, the access is through the use of a key or security identity system.

Only the authorized and well-trained personnel can access the restricted access location.

Installation and operation

• Install the rack cabinet and the associated equipment at a site where the ambient temperature (special room cooling equipment may be required) stays lower than 40°C.

• Install the power source socket outlet near the enclosure where it is easily accessible and ground the rack cabinet.

• Secure airow clearance inside and around the rack cabinet.

• Secure an 18 to 20 cm clearance on the rear side.

• Do not cover the enclosure openings.

• Route the cables inside the rack cabinet.

• Do not leave drive bays empty as it will affect airow efciency.

• Secure each enclosure module using its retention screws.

• Place power cords and other cables away from foot trafc. Do not place items on top of power cords and ensure that they do not rest against data cables.

• Install all modules to the enclosure before turning on the systems.

• Ensure that the correct power range is tested before turning on.

• DO NOT remove the covers or replaceable modules if they are not faulty.

• If the system is not used for a long period of time, disconnect it from the power outlet to avoid transient over-voltage.

• For power source redundancy, please ensure that the two PSUs are plugged into two different power sources (i.e. different circuit breakers).

Service and maintenance

• Keep the faulty module in place until you have a replacement unit; an empty module greatly affects the airow efciency within the enclosure.

• During service operation, place the enclosure on a soft and clean surface to prevent exterior damage. Do not place tools or other items on top.

• When transporting the enclosure, repackage all disk drives separately in the original package foam

blocks. Replaceable modules can stay in the enclosure if you are using the original package; if not,

repackage them separately as well.

• Disconnect the power cords before servicing or cleaning the enclosure.

• Use a slightly moistened paper sheet or cloth for cleaning. Avoid using liquid or sprayed detergent.

• When replacing components, insert them as gently as possible while assuring full engagement. Vibration and shock can easily damage hard drives.

• Only qualied service personnel should open the enclosure.

• Contact service personnel if any of the following situations occurs:

• The power cord or plug is damaged.

• The enclosure has been exposed to moisture.

• The system has not been working properly.

• The enclosure was dropped against a hard surface.

• The enclosure shows obvious signs of breakage.

• To move the enclosure, more than one person might be necessary due to its weight. Drives should be removed from the enclosure beforehand.

Important notice

The use of Infortrend certied components is strongly recommended to ensure compatibility, quality,

and normal operation with your Infortrend products. Please contact your distributor for a list of Infortrend

certied components (e.g. SFP, SFP+, HBA card, iSCSI cable, FC cable, memory module, etc.).

ESD precautions

• Handle the modules by their retention screws, ejector levers, or the module’s metal frame/faceplate only. Avoid touching the PCB boards or connector pins.

• Use a grounded wrist strap and an anti-static work pad to discharge static electricity when installing or operating the enclosure.

• Avoid dust, debris, carpets, plastic, vinyl, and Styrofoam in your work area.

• Do not remove any module or component from its anti-static bag before installation takes place.

Drives must not be stacked on top of each other without their protective drive trays. Even when drives

are xed in the drive trays, contacting the exposed PCB or rear-side interface may damage the drives.

Chapter 1: Product Introduction

Product introduction

This chapter introduces the look and feel of EonStor DS 3000 systems, features, and the supported components.

1.1 Overview

This manual introduces EonStor DS 3000 systems that support 12 Gbps SAS hard drives. The systems are designed to utilize 2.5-inch and 3.5-inch hard drives. Drive capacity can be expanded by attaching expansion hard drive enclosures.

1.1.1 Model variations

The EonStor DS 3000 systems are available in a variety of form factors.

2U systems

3U system

DS 3012U

DS 3024 UB

DS 3016U

4U systems

DS 3024U

1.1.2 Major components

NOTE: Upon receiving the system, check the package contents and compare them to the Unpacking List. If one or more of the modules are missing, please contact your system vendor.

Controller and interface

The system has controllers, and each controller comes with pre-installed DIMM modules. It also has a

CBM (cache backup module), a module that has a super capacitor and an FBM (ash backup module).

With the CBM, the cached data is quickly distributed to the FBM to save the data permanently with the support of the super capacitor if power outage occurs. With the super capacitor’s fast-charging feature, it can distribute a fair supply of power to the controller, so the controller can save cache data to the FBM immediately and permanently.

Also, the embedded rmware features earth-friendly and smart algorithms that you can use to customize

your system’s hardware settings such as power-saving modes, variable fan speeds, and exiled drive handling.

Expansion controller and interface

The expansion enclosure is managed by the expander controllers that distribute data ow to individual

disk drives and report the operating status through a proprietary enclosure service via in-band protocols. The enclosure, along with other expansion systems, connects to a SAN system and serves as a building

block of a scalable conguration.

For supported protocols, the rmware supports communications with enclosure devices, SAS/SATA disk

drives, and a SAN system that features SAS expansion ports.

For physical connection, the SAS interface provides easy cabling routes via mini-SAS connectors. With the backplane-adapting SAS or SATA drives, the system can support enterprise-class SAS, Near-line SAS, and cost-effective SATA-II or SATA-III hard drives or SSDs. This connection is ideal for adding large capacity storages to a storage pool.

1-2 Chapter 1: Product introduction

Power supply unit with built-in cooling module

For 2U and 3U series, two cooling modules are built into the PSU to protect the system from overheating

while the two hot-swappable PSUs provide constant power to the system. The modular architecture of

the system and easy accessibility to all major components provide you an easy maintenance.

For 4U series, there are two types of cooling modules:

• The redundant cooling type is located at the center of the enclosure, which independently ventilates the system and keeps the operating temperatures under optimal condition.

• The cooling type, which is built with the PSU, helps with the PSU’s temperature.

• Elevated temperature: If the temperature breaches the upper threshold set for any of the interior

temperature sensors.

NOTES:

• The PSUs have specic installation orientations for left and right cooling module slots. Refer to the label at the back of the expansion.

• There are two upper temperature thresholds: one for event notication and the other for triggering high fan rotation speed.

1-11EonStor DS 3000 Series Hardware Manual

WARNING!

• If any of the LEDs lights up in red, please contact your local vendor to request for a replacement

immediately.

• When removing the system cooling module, pull the module for about 3 inches then wait for at least

10 seconds before removing the whole module from the enclosure.

• DO NOT run the system with faulty cooling module(s) as it may cause disruption of the airow

resulting in overheating.

CAUTION! Keep your body away from the moving parts of the system.

1.4.4 Super capacitor and ash backup module

The DS 3000 series system also has a CBM (Cache Backup Module), which is comprised of a super

capacitor and ash backup module, installed in the controller. The super capacitor stores cached data to the ash backup module permanently in case of power interruption or outage.

NOTE: The super capacitor is partially charged when shipped. When you turn ON the system, the super capacitor charges to its full capacity for a few minutes. If it is not charging, there may be a problem. Contact your system vendor immediately. You can also check the status of the super capacitor via

SANWatch or the rmware. Refer to the manuals for more details.

1-12 Chapter 1: Product introduction

1.5 System monitoring features

This section describes the different types of system monitoring features that provide the operating status of each component.

1.5.1 Expansion enclosure support

Monitoring system

A managing DS 3000 system is aware of the status of connected expansion system’s components such as:

• Expander controller (presence, voltage, and thermal readings)

• PSU

• Cooling module

• Enclosure thermal sensor

• Service (the Service LED signals the specic enclosure)

• Disk drives

Expansion system identier

The managing system sets off the alarm and deliver the warning messages if there is a conict between

the expansion systems.

If more than one expansion system is connected to the managing DS system, each needs a unique

enclosure ID set using the rotary switch on the LED panel. For example, the rmware automatically

disconnects the second expansion system if it is connected online and comes with an ID identical to the

rst expansion system.

NOTE: The expansion system IDs are numbers 1 to 15. For more details, see section

2.3.6 Expansion connections.

Cooling module speed adjustment

If any of the detected temperature readings breaches the temperature threshold, the rmware running

on the managing DS system automatically increases the rotation speed of all cooling fans.

Expansion enclosure status monitoring

When connecting with expansion systems, you can acquire the component status with other enclosures via a propriety enclosure monitoring service using the in-band connectivity. No additional management connection is required.

I2C bus

The detection circuitry and temperature sensors are interfaced via a non-user-serviceable I When the expansion systems are connected to DS controllers, the component status is reported through

in-band protocols over expansion links, which is managed by a proprietary enclosure service.

C bus.

Firmware (FW) and SANWatch

• Firmware: The rmware (FW) is preloaded and is used to congure the system. Access the FW via a terminal emulation program running on a management computer connected to the system’s serial port.

• SANWatch: SANWatch is another browser-based GUI (graphic user interface) software that you can install into a local or remote computer and access via the network. The managing system communicates with the array via connection of the existing host links or the Ethernet link to the array’s Ethernet port.

1-13EonStor DS 3000 Series Hardware Manual

1.5.2 Audible alarms

The system comes with audible alarms that are triggered when certain active components fail or

when specic controller or system thresholds exceed. Whenever you hear an audible alarm, you must

determine the cause and solve the problem immediately.

Event notication messages indicate the completion or status of array conguration tasks and are

always accompanied by two or three successive and prolonged beeps. You can turn off the alarm using the mute button on the front panel.

WARNING! Failure to respond when an audible alarm is set off can lead to permanent damage to the system. When you hear an audible alarm, solve the problem immediately.

1.6 Hot-swappable components

The system also has a number of hot-swappable parts that you can change while the system is still online without affecting its operational integrity.

These hot-swappable components are user-maintained:

• Controller modules (dual-controller models)

• PSU (including cooling modules)

• Hard drive

IMPORTANT! Only remove these hot-swappable components when replacement is needed.

NOTE: A normal airow ensures sufcient cooling of the system and this can only be attained when

all components are properly installed. Remember to only remove the failed component if there is already a replacement. For more information on replacing hot-swappable components, see chapter System maintenance.

2.2.3 Installing the hard drives

This section gives you an overview of the hard drive requirements, installation, and important notices that you must take note.

NOTE: The hard drives are purchased separately.

IMPORTANT!

• Ensure to install the enclosure to the rack rst before installing the hard drives to the enclosure’s drive bay.

• You must install at least four (4) hard drives for RAID 5 conguration or ve (5) hard drives for RAID

6 conguration to create an initial volume.

Hard drive installation prerequisites

When purchasing hard drives, ensure to consider the following factors:

• Capacity (Mb/Gb)

Purchase the hard drives that have the same capacity. This SAN storage use the least common denominator approach, which means that the maximum capacity used in each drive to create a RAID array is the maximum capacity of the smallest drive. We strongly suggest to use large storage capacity hard drives.

IMPORTANT!

• The hard drives may carry different block numbers, which means that the capacity may not be the same even if they are of the same model with the same rate capacity made by the same manufacturer.

• When conguring the hard drives into a RAID array, you can use a smaller capacity as the

maximum disk capacity in every hard drive. For conguration options, refer to the interface-specic rmware manual that came with your enclosure.

• Prole

The drive trays and bays of the system are designed for 2.5-inch or 3.5-inch hard drives, depending on your EonStor storage system.

• Drive type

The system uses 12 Gbps SAS, SATA, and near-line 2.5-inch and 3.5-inch hard drives.

IMPORTANT!

• Ensure that you purchase the correct hard drives.

• If you prefer using SATA hard drives in the attached expansions, ensure that you purchase MUX kits.

2-7EonStor DS 3000 Series Hardware Manual

Keying notch

Understanding the MUX kit’s port mechanism

If you install a SATA hard drive in a dual-controller system, this may require an MUX board. The MUX

board is paired with a hard drive in order to switch data signals between controllers A and B’s signal

ports.

Backplane

Under normal circumstances, the controller B’s signal ports is in standby mode.

SAS and SATA interfaces

The SAS interface features a dual-ported connectivity with pins on both sides of its connector while the SATA drives have only one port. In a redundant-controller system, the MUX-supported drive trays must be separately purchased and applied. The single-controller expansion systems do not require MUX kit.

IMPORTANT!

• ONLY install the drive trays to the system if the system is already mounted to the rack. If the hard drives are installed to the system before mounting to the rack, the system will be heavy to mount and possible impact during installation may damage the hard drives.

• Handle the disk drives with extreme care and observe all ESD prevention procedures when installing the hard drives.

• ONLY use the screws that are bundled in the system package. Securing the drives with longer screws may damage them.

2.3 Connections

This section details the connection procedures of DS 3000 system to the expansions, power source,

connection status, topologies, and other connection congurations.

2.3.1 General considerations in connecting devices

When selecting the number of hard drives to assemble a logical drive, the host channel bandwidth and the performance of each drive must be considered. It is a good practice that you calculate the performance against the host port bandwidth when designing an application topology.

For example, if eight drives are included in a logical drive and is associated with a host ID (LUN mapping), the combined performance of this logical drive must estimate the channel bandwidth. If two 6-drive logical arrays are associated with two IDs residing in a single host channel, there may be a trade-off with the performance.

If your system comes with a total of eight or more host ports, we recommend that you use more disk drives to an expansion so that you can create a host-port that corresponds to 6-member logical drives (RAID 5) or 8-member logical drives (RAID 6). These logical drives bring up the bandwidth of each host.

You must also take note of these considerations:

• A spare drive that carries no data stripes and does not contribute to disk-level performance. For performance data information of your hard drive, refer to its documentation.

• Disk drives in the same logical array must have the same capacity, but it is preferred that all drives in the chassis have the same capacity.

• Disk drives in the same logical drive must have the same capacity, but it is preferred that all disk

drives in a chassis have the same capacity. Tiered storage conguration is supported in this setup. However, you must not include both SAS and SATA drives in a logical drive.

• A spare drive must have a minimum capacity equivalent to the largest drive that needs replacement. If the capacity of the spare drive is less than the capacity of the drive to be replaced, the controller will not proceed with the failed drive rebuild.

• When rackmounting, leave enough space for the cables. DO NOT bend them to a diameter of less than 76 mm (3 inches).

2-16 Chapter 2: Hardware installation

• When connecting between devices, follow all the specications. Pay attention to the signals and avoid electronic noise from adjacent interfaces. DO NOT put power cords on optical cables.

• Route the cables away from places where it can be damaged by other devices such as fan exhaust

or foot trafc.

• DO NOT overtighten, twist, or bend the cables.

Conguring the host-side topologies

When conguring host-side topologies, avoid the points of failure. It is recommended that the host ports are connected to at least two HBAs.

NOTES:

• To manage the fault-tolerant data paths and optimize data throughput on multiple data paths, you must apply MPIO software or other multipathing utilities such as Linux Device Mapper.

• Host port channel designation may vary by system. Refer to the topologies of this manual to create your own connections that suit your needs.

Conguring the host-side parameters

For the host-side parameters, we strongly recommend that you use the default settings of your system. If you need to adjust the host-side parameters, consult your on-site technical personnel or seek technical support from your vendor.

Familiarizing the Maximum Concurrent Host LUN Connection (Nexus in SCSI)

The menu option Max Number of Concurrent Host-LUN Connection allows you to set the maximum number of concurrent host LUN connections. This is the arrangement of the controller internal resources to use with a number of current host nexus.

For example, if you have four hosts (A, B, C, and D) and four host IDs/LUNs (IDs 0, 1, 2, and 3) in a conguration, where:

• Host A accesses ID 0 (one nexus)

• Host B accesses ID 1 (one nexus)

• Host C accesses ID 2 (one nexus)

• Host D accesses ID 3 (one nexus)

These connections are queued in the cache, which are called four nexus. If there is an I/O in the cache with these four nexus and another host I/O comes with a nexus different from the four in the cache (e.g. host A accesses ID 3), the controller returns as busy. This happens with the concurrent active nexus. If the cache is cleared, it accepts four different nexus again. Many I/O operations can be accessed via the same nexus.

Knowing Maximum Queued I/O Count

The menu option Maximum Queued I/O Count allows you to congure the maximum number of I/O operations per host channel that can be accepted from the servers. The predened range is from

1 to 1024 I/O operations per host channel. You can also choose Auto, which sets the automatic

conguration. The default value is 256 I/O operations. The appropriate setting for this option depends

on how many I/O operations the attached servers are performing. This varies according to the amount of the host memory present as well as the number of drives and their respective sizes. Usually, the optimum performance occurs from using Auto or 256 settings. For more information, refer to the

rmware manual that came with your system.

2-17EonStor DS 3000 Series Hardware Manual

2.3.2 Fibre-Host connections

The Fibre Channel standard allows optical connections. The optical cables are used over long distances

and have been proven to be more reliable. Due to the demands of high transfer rates, optical cables are

preferred for a 4 Gbps, 8 Gbps, or 16 Gbps ber connectivity and they are not vulnerable to EMI.

The bre host ports are connected to bre channel host adapters (HBA), that feature SFP interface with full duplex transfer support in a PCIe interface. For the latest certied items, please contact the vendor

near you.

WARNING!

• All bre cables are sensitive and must be handled with care. To avoid interference, the cabling path must be carefully planned without the cables getting bent.

• Lasers are hazardous and may cause blindness or permanent eye damage. Use them with utmost caution. Never look directly when lasers are turned on or operating.

Detecting auto speed

Speed auto-detection is specied by the Fibre channel standard. If a 16 Gbps port is connected to an

8 Gbps port, the speed slows down at 8 Gbps. If there are 16 Gbps ports on both ends of the link, the speed runs at 16 Gbps.

SFP/SFP+ transceivers

As SFP transceiver converts electrical data signals into light signals then transfers these signals

transparently via the optical ber. A transceiver provides bi-directional data links, a laser transmitter (for ber optic cables), LC connector, and a metal enclosure to lower the EMI.

Other features of a typical SFP transceiver include a single power supply, low power dissipation, and

hot-swap capability. It is also important that the transceiver you use meets the FC performance and reliability specications.

WARNING! The SFP transceiver has a laser diode featuring class 1 laser. To ensure safety, DO NOT remove any covers or attempt access of the inside of the device. If problems arise or if you need

technical service, contact a qualied personnel.

FC port dust plugs

Each FC port comes with a dust plug. Remove these plugs ONLY when you insert an SFP transceiver.

NOTE: Contact your vendor for the list of compatible components.

Fibre-host topologies

The bre-host standard supports three topologies:

• Point-to-point topology

A direct connection between two bre-channel devices. The simplest among the three topologies.

• FB-AL (Fibre Channel Arbitrated Loop)

The bre-channel devices are all connected to a loop. Each device is assigned to an AL_PA

(Arbitrated Loop Physical Address). FC-AL supports 124 devices in a single loop. This is the most

commonly-used topology among the three.

2-18 Chapter 2: Hardware installation

• Fabric switch

This topology can support up to 224 bre-channel devices and allows multiple devices to

communicate simultaneously. A bre switch is required to implement this topology.

IMPORTANT! If different servers need to access your logical drive, le locking, FC switch zoning, port binding, and multipath access control congurations are necessary.

Fibre cabling

Before you set up your bre cabling connection, you must:

• Create a conguration plan. In addition to cabling topologies and the list of networking components,

you must also include the rmware and software maintenance details.

• Conrm that your bre-channel cable’s loop measures 6 inches or longer.

• Ensure proper airow and keep the cables away from ventilation outlets.

To connect devices using bre cable:

1. Take out the SFP transceiver module from the static protective package.

2. Remove the dust plug from the transceiver module.

4. Insert the LC-to-LC cable to the SFP transceiver module already connected to the system. You can

hear a clicking sound, securing the cable in place.

5. Remove the protective caps on the other end of the cable, then connect to an SFP transceiver

module on a Fibre Channel switch port or a Fibre Channel host bus adapter (HBA) port.

Each logical partition is redundantly mapped to multiple host channel IDs in an AAPP (Active-Passive-

passive IDs will only become functional when a single controller fails in the system.

The MPIO driver is needed on the application servers. This driver communicates with the system

rmware and performs load balance and automated distribution of I/Os across the preferred paths

(active IDs on data paths). TPGS (Target Port Group Service) is supported so that the I/Os are routed to the preferred paths.

In this type of connection, each SFP port is connected to an FC switch then to the host adapters. Each

logical partition is mapped to a single host channel ID. If you prefer path redundancy, you can map a logical partition to IDs residing on two different channels.

management measures, such as switch zoning and port binding, must be taken to avoid multiple servers from accessing the same LUN.

If multiple servers detect a mapped volume, you have to avoid access contention using le locking software, port binding, or zoning feature of the FC switches, which limits the access from host to a specic LUN. If you have two servers in a clustered conguration, the clustering software will perform

the access control.

2-24 Chapter 2: Hardware installation

IMPORTANT!

• We suggest you to use an enclosure-specic spare drive to prevent it from participating in the rebuild of a logical drive on another enclosure. You can refer to the ID tags on the host links to see the related LUN mapping and cable links routing paths.

• You need MPIO driver to manage the access via two different HBA ports. This driver communicates

with the system rmware and performs load balance and automated distribution of I/O.

2.3.3 SAS - host connections

This section details about the connections between SAS and host using SAS cables. The SAS cables (8 pairs of 28 mm AWG) are characterized by the following:

• 100 Ohms

• Black color

• UL-approved, lead free 50 cm, 120 cm, or 170 cm in length

• Connectors must be secured to the receptacle of the chassis using a latching mechanism

WARNING! The SAS cables are sensitive and must be handled with care. To prevent interference within the rackmount, the cable routing path must be carefully planned and the cables must not be bent.

2.3.4 Ethernet - host connections

Before performing the connections between Ethernet and host, take note of the following requirements:

• Ethernet cables are user-supplied. We recommend you to use CAT5e shielded STP type network cables or cables with better performance types (important for meeting the requirements imposed by emission standards).

• Use of straight-through Ethernet cables with RJ-45 plugs.

• Use of cross-over cables. These cables can be automatically detected and rerouted for a valid connection.

See below the list of connection types:

• Directly to iSCSI initiators (software or hardware) or via the Gigabit Ethernet switches.

• To servers equipped with iSCSI HBA, preferably a hardware TOE (TCP/IP Ofoad Engine) card,

then to client stations with an Ethernet NIC or iSCSI HBA.

• The system presents its logical volumes via SCSI-like IDs and LUNs. These RAID volumes then appear as iSCSI targets via the network.

IMPORTANT! Even though the iSCSI initiator software is a cost-effective way of building an iSCSI SAN, this software initiator adds additional workload to the server CPU. We recommend you to apply iSCSI HBAs that come with TCP/IP ofoad engines in order to reduce overhead.

Network and host connection topologies

The iSCSI host ports must be connected to Ethernet network devices and iSCSI initiators that comply with IEFT iSCSI standard (RFC 3720). The network connection of the iSCSI ports is exible. The use of network connecting devices, subnet, name servers, or iSCSI management software varies from case to

case.

Note that the host NIC ports and the storage system’s iSCSI host ports must be congured in the same

subnet, and the following:

• Use the Ethernet Management port for management purposes only such as SANWatch or telnet console. This port must not be used for I/O transactions.

• Congurations such subnet or virtual LAN can separate iSCSI host links, decrease overhead, and eliminate the impact of link failure.

• Multiple arrays or logical partitions can be created and made available separately via different IDs or LUNs on host ports. Usually, a RAID5 logical drive of 8 members sometimes brings optimal array performance.

2-29EonStor DS 3000 Series Hardware Manual

IMPORTANT! If you are using Microsoft’s software initiator, uncheck the embedded MPIO function when installing the software as the MPIO selection creates conict with MPIO driver.

the high-speed FC link and FC switch.

NOTES:

• To gain optimum performance, ensure that the LAN switch

LAN switch for the systems, and the iSCSI switch

for iSCSI host link are separated.

• If they are not separated, the host may consider that the iSCSI connection is a part of the host

connection and might use it for data I/O, even if the iSCSI ports are not mapped to the host. As a result, the data transaction speed slows down to iSCSI connection’s level and the fast FC

connection bandwidth may be spent without use.

2.3.6 Expansion connections

A SAS host link is bundled per expansion package. If you need to purchase other cables, or if you need other cables of different lengths, contact your vendor.

Before conguring the expansions, you must take note of the following important points:

• For a cleaner and clutter-free rack system, have a carefully planned routing paths when connecting between systems.

• All SAS cables are sensitive and must be handled with care. DO NOT bend or twist the cables when connecting the systems installed to the rack.

Conguring the SAS expansion

The SAS expansion port connects to expansion systems. For dual-controller systems, each expansion port connects to a controller of another expansion system, making fault-tolerant links to different SAS domains.

The following principles apply to SAN storage and expansion system connections:

• Dual-controller SAN storage connects to a single-controller expansion system

• Single-controller SAN storage connects to a single-controller expansion system

• A longer cable is available in making expansion links with a dual-controller conguration. If you need to connect expansion systems from two opposite directions, you may need a longer cable. Routing between two different connections can avoid loss of data links if one expansion fails to operate.

Setting the expansion IDs

Each expansion system must have a unique ID and you can congure the ID via the rotary ID switch. To set the expansion IDs, use a small at-blade screwdriver.

You must take note of the following when setting the IDs on the expansion system:

• Set the IDs from 1 to 15. The order starts from the expansion that is closest to the managing DS enclosure.

• Ensure to set a unique ID on each enclosure so that the SAS WWN addresses of the disk drives are properly assigned. The

SAN storage system rmware automatically manages these

addresses.

2-37EonStor DS 3000 Series Hardware Manual

Conguration rules

To connect the SAS interfaces across SAN storage and expansion systems, you must take note of the following:

• Fault-tolerant links in a dual-controller combination

Corresponding to the dual-port interfaces of the SAS drives, two physical links are available per

disk drive, routed across the backplane board, then to a SAS expander, and interfaced via a 4x wide external SAS port.

• With data paths via separate SAS domains

Access to disk drives can be continued in the event of a failure from a cable link or SAS expansion

controller.

2-38 Chapter 2: Hardware installation

• Fault-tolerant links to SAS disk drives

- The SAS expansion cables are bundled with the expansion systems. Take note that if there are

many expansion systems connected, a longer SAS external cable, approximately measured 120 cm, may be needed to connect an expansion system from the opposite direction for a higher redundancy.

- One expansion link connects the expansion system from a SAN storage system with HBA/

RAID card to the nearest expansion system, then to the most distant expansion system. Another expansion link connects to the most distant expansion system, from the opposite

direction to the rst expansion system from the SAN storage system.

- Each expander controller on the SAS expansion system controls a SAS domain that connects

to one of the alternative interfaces of the disk drives in the enclosure. For example, one expander unit controls Domain A while the other expander controls Domain B. In a faulttolerant topology, the SAS external links always connect to the SAS ports of the same SAS domain.

- Identify the SAS domains by the location of the expanders: the upper controller is controller A,

the lower one is controller B.

- On a SAN storage system, each controller is considered as managing a separate SAS domain.

With the help of the port selector mechanism on the MUX boards, the idea of SAS domain applies even when SATA drives are used in a dual-controller expansion system.

4.1.5 Replacing the CBM (Cache Backup Module) components

The CBM is comprised of a super capacitor and the FBM (ash backup module). The super capacitor allows your controller to provide more power during a power outage, supporting the controller to save the data to the FBM.

WARNING! Ensure that you have the replacement on hand before replacing your current CBM.

Super capacitor fault conditions and precautions

If a super capacitor leaks, gives off bad odor, generates heat, becomes discolored or deformed, or

appears abnormal when charging or storing, remove it from the system immediately. These issues may be due to the following:

• The temperature sensor on the system’s charger circuit reports the temperature that exceeds the

preset threshold. The charger circuit enters to a low power and self-protection state.

• A super capacitor module has been charged for more than 10 minutes. When this occurs, the charger enters a timer fault state. Charging resumes automatically after you remove or reinstall the super capacitor, or after you reset the system.

When reinstalling/replacing the super capacitor, remember these precautions:

• ONLY use a replacement super capacitor supplied by an authorized distributor. Use of other

capacitors voids your system’s warranty.

• ONLY dispose your used/defective super capacitor at an authorized battery disposal sites.

• DO NOT place the super capacitor near a heat source.

• DO NOT immerse/submerge the super capacitor in water or other liquids.

• DO NOT disassemble or modify the super capacitor.

• DO NOT pierce, strike, throw, or exert pressure on the super capacitor.

Replacing the super capacitor

To replace the super capacitor:

1. Shut down your system, unplug the power cords, then remove the controller. Wait for a minute for

the remaining electric current to dissipate.

NOTE: See section 4.1.3 Replacing the controller module for details.

2. From the controller board, disconnect the 4-pin connector from the charge board.

4-11EonStor DS 3000 Series Hardware Manual
