Cache

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

• Write-back or write-through caching. The controller writes user data in the cache memory on the

module rather than directly to the drives. 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 drive array.

• Read-ahead caching. The controller detects sequential array access, reads ahead into the next

sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the contr oller immediat ely loads the data into the s y stem memory, avoiding the latency of

a disk access.

NOTE: See HP P2000G3MSA System SMU Reference Guide for more information about volume cache

Controller Module

CompactFlash

options.

Transportable CompactFlash

During a power loss or array controller failure, data stored in cache are saved off to non-volatile memory (CompactFlash). These data are 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.

In single-controller configur ati on s, i f the contr o ller has f ailed or does no t start , and the C ac he S tatu s LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk (See Controller failure in a single-controller configuration on page 51 for more information).

CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the

CompactFla sh f rom the failed controller to the r e placement controller using a procedure outlined in the HP Controller Module Replacement Instructions, shipped with the replacement control ler. Failure to use this

procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual controller configurations featuring one healthy peer controller, there is no need to

transport a failed controller’s cache to a replacement controller because the cache is duplicated between the controllers.

Super-capacitor pack

To pr otect RAID controller cache in case of pow er failure , P2000 G3 MSA Sy stem contr ollers ar e equipped with super-ca pacitor technology, in conjunction with CompactFlash memory, built int o each controller module to provide unlimited cache memory backup time. The super-capacitor pack provides energy for backing up unwr itten data in the w rite cac he to the CompactF lash in the e vent of a po w er failure . Un wr itten data in CompactFlash memory are automatically committed to disk media when power is restored. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

HP P2000 G3 SAS MSA System User Guide 23

Connecting controller and drive enclosures

P2000 G3 MSA System controller enclosures — available in either 24-drive (2.5”) or 12-drive (3.5”) chassis — support up to eight enclosures (including the controller enclosure) for storage/expansion, or a maximum of 149 disk drives. You can also configure drive enclosures of mixed type, as shown in Table 3 on page 26.

The firmware supports both straight-through and reverse SAS cabling. Reverse cabling allows any drive enclosure to fail — or be removed — while maintaining access to other enclosures. Fault tolerance and performance requirements determine whether to optimize the configuration for high availability or high performance when ca bling. P2000 G3 MSA S ys tem contr oller enc losur es support both 3Gbps and 6Gbp s internal disk drive speeds, together with 3Gbps and 6Gbps expander link speeds. Controller and expansion modules are identified by <enclosure-ID><controller-ID>. When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance.

For e x ample , Figure 6 on page 29 sho ws controller module 1A is connected t o e xpansi on module 2A, with a chain of connections cascading down (blue). Controller module 1B is connected to the lower expansion module (5B) of the last drive enclosure, with connections moving in the opposite (reverse) direction (green).

NOTE: P2000 G3 MSA System controller enclosures support hot-plug replacement of redundant

controller modules, fans, power supplies, and I/O modules. Hot-add of drive enclosures is also supported.

Connecting controller and D2700 6Gb drive en closure

A D2700 6Gb drive enclosure, supporting 6Gb internal disk drive and expander link speeds, can be attached to a P2000 G3 SAS MSA System LFF or P2000 G3 SAS MSA System SFF controller enclosure using supported mini-SAS to mini-SAS cables of 0.5m to 2m length (see Figure 3 on page 28).

Connecting controller and P2000 6Gb 3.5" 12-drive enclosure

A P2000 6Gb 3. 5" 12-dri v e enc lo sur e, suppo rting 6Gb int er nal disk dr ive and ex pander li nk speeds , can be attached to a P2000 G3 S A S MSA Sy st em LFF o r P2000 G3 S A S M SA Sy ste m SFF co ntr oll er enc lo sur e using supported mini-SAS to mini-SAS cables of 0.5m to 2m length (see Figure 2 on page 28).

Connecting controller and MSA70 3Gb drive enclosure

P2000 G3 MSA S y stem controller s support MS A70 3Gb drive enclosures r unning fir m war e v ersi on 2.1 8 or later.

For info rmation about the MSA70 3Gb drive enclosure, including detailed steps to upgrade the firmware, see the HP StorageWorks 70 Modular Smart Array Enclosure User Guide located on the MSA2000 Software Support/Docu mentation CD shipped with your product, or at http://hp.com/support/manuals

If you connect a 3Gb drive enclosure to a 6Gb controller enclosure, data throughput occurs at the drive enclosure’s 3Gb data rate (see Figure 5 on page 29).

Diagrams within this document use IOM (I/O Module: also referred to as expansion module).

Connecting controller and MSA2000 3Gb 3.5" 12-drive enclosure

Connecting an MS A2000 3 . 5” 12-driv e encl osure to a P2000 G3 S AS M S A S yst em LFF or P2000 G3 S A S MSA System SFF requires supported mini-SAS to SAS cables. If you connect a 3Gb drive enclosure to a 6Gb controller enc losur e, data thr oughput occ urs at the dr iv e enc losur e’s 3Gbp s data rate (s ee Figure 4 on page 28).

Additional cabling considerations

P2000 G3 MSA System controller enclosures (both LFF and SFF models) support each of the drive enclosures listed above. However, when cabling supported drive enclosures of mixed type, consider the follow ing fact ors r egarding com ponents equipped wi th SA S2 . 0 and S AS1.1 expanders (labeled in Figure 1 on page 25):

• P2000 G3 MSA System controller enclosures support 6Gb and 3Gb drive enclosures.

• To avoid performance limitations in a mixed-type drive enclosure environment, cable 3Gb drive

enclosures after 6Gb drive enclosures as shown in Figure 10 on page 32. Do not mix 6Gb and 3Gb disk drives in the same enclosure.

• Performance will be limited if a 3Gb drive enclosure is cabled before a 6Gb drive enclosure

Powering on/powering off

Before powering on the enclosure for the first time:

• Install all disk drives in the enclosure so the controller can identify and configure them at power-up.

• Connect the cables and power cords to the enclosures as explained in the installation sheet.

NOTE: P2000 G3 controller enclosures and s ome P2000 G3 drive enclosures do not have power

switches. They power on when connected to a power source, and they power off when disconnected.

• Generally, when powering up, make sure to power up the enclosures and associated data host in the

following order:

•Drive enclosures first This ensures that disks in the driv e enclosure have enough time to completely spin up before being

scanned by the controller modules within the controller enclosure. While enclosures power up, their LEDs blink. After the LEDs stop blinking —

and back of the enclosure are amber — been detected. See LED descriptions on page 57 for descriptions of LED behavior.

• Controller enclosure next Depending upon the number and type of disks in the system, it may take several minutes for the

system to become ready.

• Data host last (if powered down for maintenance purposes).

4 Connecting hosts

Host system requirements

Data hosts connected to P2000 G3 MSA System arrays must meet the following requirements:

• Depending on your system configur ati o n , dat a hos t operating syste ms ma y require that multi-pathing is

supported.

TIP: See the HP MSA System VDS and VSS Hardware Providers Installation Guide and HP MSA

System MPIO DSM Installation Guide to aid in planning and implementing your MPIO DSM

installation.

If fault tolerance is required, then multi-pathing software may be required. Host-based multi-path 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 Windows Server MPIO DSM with Windows Server 2003. To obtain the MPIO DSM, go to the HP MSA products page at http://www.hp.com/go/msa Products.

• Use native Microsoft MPIO DSM support with Windows Server 2008. Use either the Server Manager or the command-line interface (mpclaim CLI tool) to perform the installation. Refer to the following web sites for information about using the Windows 2008 native MPIO DSM:

http://support.microsoft.com/gp/assistsupport http://technet.microsoft.com (search the site for “multipath I/O overview”)

5 Connecting to the controller CLI port

Device description

P2000 G3 MSA System controllers feature a new command-line interface (CLI) port used to cable directly to the controller and initially set IP addresses, or perform other configuration tasks . This port differs from G1 and G2 controllers . It employ s a mini-USB T y pe B for m factor, and requires a new cable and additional support so that a server or other compute r running a Li nux or W indow s oper ating sy stem can r ecogni z e the controller enclosure as a connected device. Without this support, the computer might not recognize that a new device is connected or might not be able to communicate with it. For Linux computers, no new driver files are needed, but a Linux configuration file must be created or modified.

For Windows computers, a special device driver, gserial.inf, must be downloaded from a CD or HP website, and installed on the computer that will be cabled directly to the controller’s CLI port.

NOTE: Directly cabling to the CLI port is an out-of-band connection because it communicates outside the

data paths used to transfer information from a computer or network to the controller enclosure.

An in-band connection can also be used to configure a new controller. If used, cabling to the CLI port might not be necessary. The in-band method uses the MSA Device Discovery utility on the Software Support/Documentation CD that is included with your system, and is the best way to discover the controller’s IP addresses automatically, so that you can use them to log into and manage your controllers using a web browser for SMU, or telnet for the CLI. See Using the MSA Device Discovery Tool to discover

controller’s IP addr esse s for instr ucti ons about ho w to use the M SA De vi ce Disco very T ool o ver y our e xis ting

in-band connection to discover controller IP addresses without using the CLI port.

Preparing a Linux computer before cabling to the CLI port

Although Linu x operating systems do not require installati on o f a device driver, certain parameters mus t be provided during driver loading to enable recognition of the P2000 G3 MSA System controller enclosures. To load the Linux device driv er with the correct parameters, the following command is required:

modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1

Optionally, the information can be incorporated into the /etc/modules.conf file.

Downloading a device driver for Windows computers

A Windows USB device driver download is provided for communic ating directly with the controller’s CLI port using a USB cable to connect the controller enclosure and the computer. If you use the MSA Device Discov ery Tool you may not need the download. Ho wever, you can dow nlo ad it an d inst all it f or f u ture use .

NOTE: Access the download from your HP MSA products page at http://www.hp.com/go/p2000.

Select Models — select your product — select HP Support & Drivers, then select Download drivers and software.

The USB device driver is also available from the P2000 G3 Software Support/Documentation CD that shipped with your product.

Obtaining IP values

Using the MSA Device Discovery Tool to discover controller’s IP addresses

The MSA Device Discovery Tool provides the optimal approach for setting network port IP addresses on Windows or Linux platforms. For help w ith configuring your P2000 G3 MSA System products, see the P2000 G3 Software Support/Documentation CD that shipped with your product.

1. Locate th e P2000 G3 Software Support/Documentation CD included with your P2000 G3 MSA

System storage device.

HP P2000 G3 SAS MSA System User Guide 41

2. Insert the P2000 G3 Software Support/Documentation CD into the CD drive on a Linux or Windows

computer on the network that is connected to your controller enclosure.

3. Use Autoru n or manually start the CD.

The MSA Device Discovery Tool will run.

4. Fo llow the instructions to discover the IP addresses of the controller or controllers.

Record these IP addresses so that you can specify them whenever you manage the controllers using SMU or the CLI.

Alternatively, you can set network port IP addresses using CLI on HP-UX, Windows, and Linux platforms.

Setting network port IP addresses using DHCP

1. Look in the DHCP server’s pool of leased addresses for two IP addresses assigned to “HP

StorageW orks MSA Storage.”

2. Use a ping broadcast to try to identify the device through the host’s ARP table.

If you do not have a DHCP server, y ou will need to ask your system administrator to allocate two IP addresses, and set them using the CLI during initial configuration (described below).

Setting network port IP addresses using the CLI port and cable

If you did not use the M S A Dev i ce Disco ve ry T ool to s et networ k port IP values, set the m manually u sing the CLI port and cable. If yo u ha v e not done s o alr ead y, you need to enable your system for using the CLI port.

NOTE: For Linux systems, see Preparing a Linux computer before cabling to the CLI port on page 41. For

Windows systems see Downloading a device driver for Windows computers on page 41.

Network ports on controller module A and controller module B are configured with the following default values:

• Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)

• IP Subnet Mask: 255.255.255.0

• Gateway IP Address: 10.0.0.1

If the default IP addresses are not compatible with your network, you must set an IP address for each network port using the CLI embedded in each contr o ller module. The CLI enables you to access the sy s tem using the USB (universal serial bus) communication interface and terminal emulation software. The USB cable and CLI port support USB version 2.0.

Use the CLI commands described in the steps below to set the IP address for the network port on each controller module . Once new IP addr es ses ar e se t, y ou can change them a s needed using SMU. Be sur e to change the IP address via SMU before changing the network configuration.

NOTE: Changing IP settings can cause management hosts to lose access to the storage system.

1. From your network administrator, obtain an IP address, subnet mask, and gateway address for

controller A, and another for controller B. Record these IP addresses so that you can specify them whenever you manage the controllers using

SMU or the CLI.

2. Use the pro vided USB cable to connect controller A to a USB port on a host compu ter. The USB mini 5

male connector plugs into the CLI port as shown in Figure 1 4 (generic controller module is shown).

CLI port connection

P2000 G3 MSA System controllers feature a ne w CLI port emplo y ing a mini-USB Type B form factor. If you encounter problems communicating with the port after cabling y our computer to the USB device, you may need to either download a device driver (Windows), or set appropriate parameters via an operating system command (Linux). See Connecting to the controller CLI port for more information.

Fault isolation methodology

P2000 G3 MSA System controllers provide many ways to isolate faults within the system. This section presents the basic methodology used to locate faults and the associated FRUs (Field Replaceable Units).

The basic fault isolation steps are:

• Gather fault information, including using system LEDs.

• Determine where in the system the fault is occurring.

• Review eve nt logs.

• If required, isolate the fault to a data path component or configuration.

Gather fault information

When a fault occurs, it is important to gather as much information as possible. Doing so will help you determine the correct action needed to remedy the fault.

Begin by re vi e w ing the reported f ault . Is the fa ult r elated to an inter nal data path or an e xter nal data path? Is the fault related to a hardware component such as a disk drive module, controller module, or power supply? By isolating the fault to one of the components within the storage system, you will be able to determine the necessary action more rapidly.

Determine where the fault is occurring

Once you have an understanding of the reported fault, review the enclosure LEDs. The enclosure LEDs are designed to alert users of any system faults, and might be what alerted the user to a fault in the first place.

When a fault occurs, the Fault ID status LED on an enclosure’s right ear (see Front panel components on page 17) illuminates. Check the LEDs on the back of the enc losure t o narr o w the fault t o a FRU , connectio n, or both. The LEDs also help you identify the location of a FRU reporting a fault.

Use SMU to ver i fy any faults found while viewing the LEDs. SMU is also a good tool to use in determining where the fault is occurring if the LEDs cannot be viewed due to the location of the syst em. SMU provides you with a visual representation of the system and where the fault is occurring. It can also provide more detailed information about FRUs, data, and faults.

Review the event logs

The event logs record all system events. It is very important to review the logs , not only to identify the fault, but also to search for events that might have caused the fault to occur. For example, a host could lose connectivity to a virtual disk if a user changes channel settings wi thout taking the storage resources assigned to it into consideration. In addition, the type of fault can help you isolate the problem to hardware or software.

The Log Collector utility allows customers to gather log information for use during support calls. See the P2000 G3 Software Support/Documentation CD that ships with your product for details.

Isolate the fault

Occasionally it might become necessary to isolate a fault. This is particularly true with data paths, due to the number of components comprising the data path . F or e xample , if a ho st-side data err or occ ur s, it could be caused by an y of the components in the data path: controller module, cable, or data host.

HP P2000 G3 SAS MSA System User Guide 47

If the enclosure does not initialize

It may take up to two minutes for the enclosures to initialize. If the enclosure does not initialize:

• Perform a rescan.

• Power cycle the system.

• Make sure the power cord is properly connected, and check the power source that it is connected to.

• Check the event log for errors.

Correcting enclosure IDs

When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physic al cabling order. This is because the controller might have been previously attached to some of the same enclosures dur ing f actory testing and it attempts to pre serve the pr e v i ous enc losur e IDs if pos sible . To correct this conditi on, make sure that both controllers are up, and perform a rescan using SMU or the CLI. This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.

To perform a rescan using the CLI, type the following command:

rescan

To rescan using SMU:

1. Verify that both controllers are operating normally.

2. In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.

3. Click Rescan.

Controller failure in a single-controller configuration

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 super-capacitor. This process typically takes 60 s econds per 1 Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the cache memory . While the cache is be ing maintained b y the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second off and 9/10 second on.

IMPORTANT: Transportable cache only applies to single-controller configurations. In dual controller

configurati ons, ther e is no need to tr ansport a failed contro ller’s cache t o a replacement contr oller becaus e the cache is duplicated between the peer controllers.

Transporting cache

To preserve the exis ting data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to a replacement controller using a procedure outlined in the HP P2000 G3 MSA System controller replacement instructions, shipped with the replacement controller. Failure to use this procedure will result in the loss of data stored in the cache module.

CAUTION: Remove the controller only after the copy process is complete, which is indicated by the

Cache Status LED being off.

Isolating a host-side connection fault

During normal operation, when a controller module host port is connected to a data host, the port’s host link status LED and host link acti v ity LED are gr een . If ther e is I/O acti v ity , the host acti v ity LED blinks gr een. If data hosts are having trouble accessing the s torage system, and you cannot locate a specific fault or cannot access the event logs, use the following procedure. This procedure requires scheduled downtime.

IMPORTANT: Do not perform more than one step at a time. Changing more than one vari able at a time

can complicate the troubleshooting proce ss.

by the pre vious cable. Is the host link status LED on?

• Yes – Replace the original cable. The fault has been isolated.

• No – It is likely that the controller module needs to be replaced.

Resolving voltage and temperature warnings

1. Check that all o f the fans are wo rking by making sure ea ch power su pply’s V o l tage/Fan Fault/Service

Requir ed LED is off or by using SMU to check for yellow yield icon hardw are warnings. (In the Configuration View panel, right-click the enclos ure and select View > Overview.)

2. Make sure that all modules are fully seated in their slots and that their latches are locked.

3. Make sure that no slots are left open f or more than two minutes.

If you need to re place a module, lea ve the ol d module in place until you ha v e the r eplacement or use a blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the enclosure to overheat.

4. Try replacing each power supply one at a time.

5. Replace the controller modules one at a time.

Sensor locations

The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each controller module and expansion module, the enclosure management processor (EMP) monit ors the status of these sensors to per form SCSI enclosure services (SES) functions.

The follo wing sections describe each element and its sensors.

Power supply sensors

Each enc losure has two fully redundant power supplies with load-sharing capabilities. The power supply sensors desc ribed in the follow ing t able monit o r the voltage, cur rent, temper ature, and fans in each power supply. If the power supply sensors report a volt age that is under or over the threshold, check the input voltage.

Table 7 Power supply sensors

Description Event/Fault ID LED condition

Power supply 1 Voltage, current, temperature, or fan fault Power supply 2 Voltage, current, temperature, or fan fault

Cooling fan sensors

Each power supply includes two fans. The normal range for fan speed is 4,000 to 6,000 RPM. When a fan’s speed drops below 4,000 RPM, the EMP considers it a failure and posts an alarm in the storage system’s event log. The following table lists the description, location, and alarm condition for each fan. If the fan speed remains under the 4,000 RP M threshold, the internal enclo sur e te mperature may continue to rise. Replace the power supply reporting the fault.

Table 8 Cooling fan sensor descriptions

Description Location Event/Fault ID LED condition

Fan 1 Power supply 1 < 4,000 RPM Fan 2 Power supply 1 < 4,000 RPM Fan 3 Power supply 2 < 4,000 RPM Fan 4 Power supply 2 < 4,000 RPM

During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling.

54 Troubleshooting

Temperature sensors

Extreme high and lo w t emperatures can cause significant damage if they go unnoticed. Each controller module has six temperature sensors. Of these, if the CPU or FPGA (Field Programmable Gate Array) temperatur e reaches a shutdown value, the controller module is automatically shut down. Each power supply has one temperature sensor.

When a temperatur e f a ult is reported, it must be r emedi ed as qui c kl y as pos sible to a v o i d system damage . This can be done by warming or cooling the installation location.

9 Cache Status Green — Cache is dirty (contains unw r itten dat a) and oper ati on is

normal. Off — In a working controller, cache is clean (contains no unwritten data). Blinking green — A CompactFlash flush or cache self-refresh is in progress. Indicates cache activity (See also If the controller has

failed or does not start, is the Cache Status LED on/blinking? on

page 52). If the LED is blinking evenly, a cache flush is in progress. When a

controller module loses power and wr ite cache is dirty (contains data that has not been written to disk), the super-capacitor pack provides backup power to flush (copy) data from write cache to CompactFlash memory. When cache flush is complete, the cache transitions into s elf-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 back up pow er is depleted (3–30 minutes , depending on various factors), the system boots, finds data preserved in cache, and writes it to disk. This means the system can be operational within 30 seconds, and before the typical host I/O time-out of 60 seconds, at whic h point sy stem failure w ould cause ho st-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 each controller’s cache and one in each controller’s CompactFlash.

10 Expansion Port Status Off — The port is empty or the link is down.

On — The port is connected and the link is up.

IMPORTANT: Early versions of the P2000 G3 MSA System controller modules show network port LED

labels in reversed position: LINK is shown on the left and ACT is shown on the right. On such units, the LED labeled LINK reports ACT behavior and the LED labeled ACT reports LINK behavior.

NOTE: Once a Link Status LED is lit, it remains so, even if the controller is shutdown via SMU or CLI.

When a controller is shutdown or otherwise rendered inactive —its Link Status LED remains illuminated—falsely indicating that the controller can communicate with the host. Though a link exists between the host and the chip on the controller, the controller is not communicating with the chip. To r e s et the LED, the controller must be properly power-cycled (see Accessing SMU on page 45).

Power supply LEDs

Power redundancy is achieved through two independent load-sharing power supplies. In the event of a power supply failure, or the failure of the power source, the storage system can operate continuously on a single power supply. Greater redundancy can be achieved by connecting the power supplies to separate circ uits . DC po w er suppli es ar e equipped w ith a po w er s w itc h .

HP P2000 G3 SAS MSA System User Guide 65

Weight and placement guidelines

Refer to Physical requirements on page 67 for detailed size and weight specifications.

• The weight of an enclosure depends on the number and type of modules ins talled.

• Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its

weight is reduced by removing the power supply modules and disk drive modules.

• Do not place enclosur es in a v erti cal positi on . Always inst all and oper ate the enclo sur es in a horizontal

orientation.

• When installing enclosures in a rack, make sure that any surfaces over whi ch you might move the rack

can support the weight. To prevent accidents when moving equipment, especially on sloped loading docks and up ramps to raised floors, ensur e y ou ha v e a suff i cient number of helpers. R emove obstacles such as cables and other objects from the floor.

• To pr e v ent the r ac k from tipping, and to minimi ze personnel injury in the even t of a se ismic occ urrence,

securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the ceiling of the room.

Electrical guidelines

• These enc los ures work w i th single-phase po wer sys tems having an earth ground connecti on. To reduce

the risk of electr ic shock, do not plug an enclosure into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

• Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric

shock, always plug the cord into a grounded power outlet.

• Do not use household extension cords with the enclosures. Not all power cords have the same current

ratings. Household extension cords do not have overload protection and are not meant for use with computer systems.

Ventilation requirements

Refer to Environmental requirements on page 68 for detailed environmental requirements.

• Do not block or cover ventilation openings at the front and rear of an enclosure. Never place an

enclosure near a r adiat or or heating vent . Failure to follo w the se guideline s can caus e ov er heating and affect the reliability and warranty of your enclosure.

• Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to ensure adequate

airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures.

• Leave enough space in front and in back of an enclosure to allow access to e nclosure components for

servicing. Removing a component requires a clearance of at least 15 inches (37 cm) in front of and behind the enclosure.

Cabling requirements

• Keep power and interface cables clear of foot traffic. Route cables in locations that protect the cables

from damage.

• Route interface cables away fr om motors and other sources of magnetic or radio frequency

interference.

• Stay w ithin the cable length limitations.

Management host requirements

A local management host w ith at least one s eri al port connecti on is r ecommended for the initial ins tallation and configuration of a controller enclosure. After you configure one or both of the controller modules with an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to configure, manage, and monitor.

66 Environmental requirements and specifications

NOTE: Connections to this device must be made with shielded cables – grounded at both ends – with

metallic RFI/EMI connector hoods, in order to maintain compliance with FCC Rules and Regulations.

Physical requirements

The floor space at the installation site must be strong enough to support the combined weight of the rack, controller enclosures, drive enclosures (expansion), and any additional equipment. The site also requires suffic ient space f or installati on, oper ation , and serv ic ing the enclo sures , and suffi c ient v entilation to allo w a free flow of air to all enclosures.

Table 19 and Table 20 list enclosure dimensions and weights. Weights are bas ed on an enclosure having

a full complement of disk drives, two controller or expansion modules, and two power supplies installed. “2U12” denotes the LFF enclosure and “2U24” denotes the SFF enc losur e . T he SFF is further delineated by the standard-depth 2U24 and the new reduced-depth (short) 2U24.

Table 20 provides weight data for P2000 G3 controller enclosures and select drive enclosur es. For

68 Environmental requirements and specifications

Power cord requirements

Each enclosure equipped with AC power supply modules requires two AC power cords that are appropriate for use in a typical outlet in the des t ination country. Each power cord connects one of the power supply modules to an independent, external power source. To ensure powe r redundancy, connect the two suitable power cords to two separate circuits; for example, to one commercial circuit and one uninterruptible power source (UPS).

C Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.

• Place parts in a static-protected area before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a s tatic-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground card to a grounded workstation or computer chassis. Wrist

straps are flexible straps with a minimum of 1 megohm (± 10 percent) resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on both feet when

standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installati on, contact an authorized reseller.
