2: Installation and Use of Devices

This chapter explains installation sites for the system equipment and basic uses of removable devices.

Notes on Handling

Installation Site

The following table lists environmental conditions for installing the system equipment:

Item Allowable range

Temperature 10 to 35°C [Non-operating: -10 to 43°C] Relative humidity 20 to 80% [Non-operating: 8 to 90%] (avoid condensation) Max. wet-bulb temperature 27°C Temperature rise gradient 10°C/hour (max) Minimum clearance required 50 cm in front of equipment, 30 cm behind, and 20 cm to the right and left

Avoid installing the system equipment in the following locations:

• Location exposed to direct the sun light

• Location where temperature or relative humidity changes rapidly

• Location near a device (such as motor) generating electric noise

• Location near a device generating strong magnetic field

• Location with much dust and litter

• Location with much vibration

• Location where corrosive gas is generated such as sulfur dioxide, hydrogen sulfide, chlorine gas, or ammonia

• Location without ventilation, such as within a fully enclosed shelf or box

Ch 2: Installation and Use of Devices

Notes on Handling for Each Device

System Equipment

• Be sure to install the equipment horizontally on the floor. Avoid installing it on a table or stand. If necessary,

insert cardboard or equivalent between the equipment and the floor for adjustment.

• Avoid sitting on the equipment; otherwise you could fall off or suffer from an electric shock.

• Avoid putting vases, beverages, or similar things containing water or the equipment; introdoction of water into

the equipment could cause short-circuit.

• Avoid using the system equipment with its cover removed or with the storage bay door open; otherwise an

electric shock or a failure could be caused.

• revent the side covers from shock, because the equipment contains hard disk drives and other devices, which are

susceptible to shock.

• When moving the equipment, do not let the equipment hit surrounding materials.

• void blocking the vent holes on the front and back of the system equipment; insufficient ventilation could cause

a failure of the equipment. Inspect the vent holes for dust constantly and clean them periodically.

• Keep the door key (attached to the system equipment) properly. If you lose it, it will become necessary to replace

the entire key unit. If such is the case, consult the store where you bought the equipment.

• While the system is being started up, avoid executing keyboard resetting (Ctrl + Alt + Delete); otherwise a

system error will occur.

It is recommended that you constantly make backup copies of data to ensure uninterrupted operation. A failure in the system equipment or power outage could cause the data in your system to be lost.

Keyboard and Mouse

Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be guaranteed.

• Prevent water from splashing on the keyboard or mouse.

• When cleaning, use soft cloth such as cotton cloth with a small quantity of water sprayed. Avoid spraying water

directly on the keyboard or mouse and wiping it with wet cloth.

Displays

Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be guaranteed.

• Keep sufficient space around so that when swiveled the display does not hit any surrounding material.

• Avoid putting things on the display; otherwise ventilation could be insufficient for the display to be cooled

properly, resulting in a failure.

• eep the display away from magnets and loudspeakers to prevent color drift.

• Keep at least 70 cm between two displays to prevent interference in magnetic fields.

Internal DAT and Internal DAT Changer (Optional)

Use of a cartridge with its service life exhausted could cause a drive failure or data destruction. While not in use, remove the cartridge from the equipment. If you leave the cartridge inserted, its

service life will be shortened. Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be

guaranteed.

• Data cartridges usable in an internal DAT and internal DAT changer are:

Tape length (format) Memory capacity

Ch 2: Installation and Use of Devices

60m tape (DDS-1) 90m tape (DDS-1) 120m tape (DDS-2) 125m tape (DDS-3)

1 It is assumed that the average data compression ratio is 2.0. (The data compression ratio

depends on transfer data.)

1.3GB (uncompressed) to 2.6GB (compressed1)

2.0GB (uncompressed) to 4.0GB (compressed1) 0GB (uncompressed) to 8.0GB (compressed1) 12GB (uncompressed) to 24GB (compressed1)

The formatting modes of 60m/90m tape, 120m tape, and 125m tape differ from each other. When you use drives incompatible with each other, check the formatting modes corresponding to the drives, then decide on the tape length for the cartridge.

• The standard service life (number of uses) of a cartridge used in an internal DAT changer is 160 times. If the

number of uses exceeds 160, replace the cartridge with a new one.

• To minimize condensation, note the following:

- Use cartridges in a temperature range of 10 to 35°C and a relative humidity range of 20 to 80%.

Storecartridges containing data in a temperature range of 5 to 32°C.

- If the cartridge to be used has been placed somewhere that exceeds the allowable temperature range, leave

it at ordinary room temperature at least two hours before use.

Ch 2: Installation and Use of Devices

Internal DLT (Optional)

Use of a cartridge with its service life exhausted could cause a drive failure or data destruction. While not in use, remove the cartridge from the equipment. If you leave the cartridge inserted, its

service life will be shortened. Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be

guaranteed.

• The standard service life (number of uses) of a cartridge used in an internal DLT is 2000 times. If the number

of uses exceeds 2000, replace the cartridge with a new one.

• To minimize dew condensation, note the following:

- Use cartridges in a temperature range of 10 to 35°C and a relative humidity range of 20 to 80%.

Storecartridges containing data in a temperature range of 16 to 32°C.

- If the cartridge to be used has been placed somewhere that exceeds the allowable temperature range, leave

it at ordinary room temperature at least two hours before use.

• Internal DLTs format an unused cartridge when it is inserted into the drive. The formatting mode for an internal

DLT differs from that for an internal DLT because of difference in recording density. When you want to use a cartridge on both types of drives, use the internal DLT for formatting the cartridge before use (the recording density is 20GB/40GB (uncompressed/compressed).

Extended Board

Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be guaranteed.

Check that the slot connectors are engaged properly, then insert an extended board. Forcible insertion with the slot connectors not engaged could cause pins to be bent or broken.

Other Option Devices

Only Hitachi products are guaranteed. If products of other companies are used, operation cannot be guaranteed.

Use extreme care to protect expansion devices from shock (hitting or falling on hard material). Being precision devices, expansion devices are very susceptible to shock.

Installing SCSI Devices

This section explains how to install SCSI devices (including internal hard disks, internal CD-ROMs, and internalDATs).

Before changing the configuration of the system equipment (such as internal SCSI devices or extended boards), be sure to unplug the power cord, and wait at least 30 seconds. In some rare cases, the setup data might be changed. In such cases, turn off the system equipment, turn it on, then change the settings on the Setup Menu.

Basics on SCSI Devices

This section explains basic knowledge required for installing SCSI devices.

Outline of Operation

Installation of SCSI devices can largely be divided into the following four steps:

Install a SCSI board in the system equipment.

Set a SCSI ID and attach a terminating resistor for the SCSI device.

Install the SCSI device in the system equipment.

Connect the SCSI board with the SCSI device using a cable.

48 Hitachi PC VisionBase8450H/R Server

Ch 3: Installing Optional Devices

A terminating resistor is mounted here

Daisy Chain and Terminating Resistor

A maximum of seven SCSI devices can be serially connected to one SCSI controller. Such a serial connection is referred to as a daisy chain connection. The SCSI devices at both ends of the daisy chain require a resistor called a terminator (terminating resistor). If you attach a terminator onto another SCSI device, that SCSI device will not operate normally.

In Hitachi PC VisionBase8450H/R Server, up to six SCSI devices can be connected to one controller.

NOTE: A terminating resistor is installed for the following devices supplied as standard in the Hitachi PC

VisionBase8450H/R Server: the SCSI controller, the disk array controller board, and the platter board on which internal hard disks are to be installed.

In Hitachi PC VisionBase8450H/R Server you need not mount a terminating resistor onto removable devices; the SCSI cable to be connected already has one mounted.

SCSI IDs

SCSI IDs are numbers used to identify SCSI devices; 0 to 6 are used. Make sure that 0 is used for the SCSI ID for your starter hard disk. Be sure to set SCSI IDs so that there is no duplication within the group of SCSI devices (those within the same daisy chain) connected with the same SCSI controller.

If the same SCSI ID is used the more than one SCSI device in a group of SCSI devices connected to the same SCSI controller, the SCSI devices will malfunction.

NOTE: The SCSI ID for the SCSI controller is set to 7.

Hitachi PC VisionBase8450H/R Server 49

Ch 3: Installing Optional Devices

Mirroring and Duplexing

You can save data in two hard disks to prepare for a possible hard disk failure. This dualized data structure is useful in preventing data loss, because even if one hard disk fails, the other hard disk is still usable. There are two types of dualizing data, mirroring and duplexing.

Mirroring

The same data is stored in two hard disks connected to the same SCSI board. Storing data requires more time than non-dualized structure, because data is written successively onto the two hard disks.

Duplexing

Each of the two SCSI boards is connected to its hard disk into which the same data is written and stored at the same time, resulting in a smaller reduction in processing speed.

NOTE: Hitachi PC VisionBase8450H/R Server does not allow duplexing.

Ch 3: Installing Optional Devices

Disk Array

What is a disk array?

“Disk array” refers to the use of two or more hard disks concatenated into one logical disk. It is also called Redundant Arrays of Inexpensive Disks (RAID).

Disk array has two main advantages:

• Increasing I/O performance

By dividing data into several units and distributing them to hard disks within an array (called “data striping”), I/O performance as the entire array is better than the I/O performance obtained when each disk is separately used.

• Restoring data

Creation of an array parity enables you to restore data even if one of the hard disks within the array should fail, thereby preventing data from being lost.

Even if you use disk arrays, you cannot prevent data loss due to non-hard-disk failures, software crash, or incorrect manipulation. Make sure you create backup copies for system data in case of unexpected failures.

Types of Disk Arrays

Disk arrays are classified into six types (0 to 5) according to the RAID level. Of the six types, only RAID0, RAID1, RAID3, and RAID5 are currently usable. The method and features of each RAID level are shown below.

NOTE: Hitachi PC VisionBase8450H/R Server supports RAID0, RAID1, and RAID5 as well as RAID7, which is

used to install hard disks (used discretely) in the disk array controller.

RAID0

Data is striped extending over several hard disks.

Advantage: Throughput increases, especially for large-volume files. Disadvantage: No array parity is created; therefore, if at least one of the hard disks within the array fails, all data will be lost.

Number of hard disks required: 2 (min.) to 6 (max.)

Hitachi PC VisionBase8450H/R Server 51

Ch 3: Installing Optional Devices

RAID1

Data is stored into two hard disks, a data disk and a mirrored disk, in the same way.

Advantage: 100% data redundancy is ensured. Even if one of the two hard disks fails, it will be switched to the other hard

Disadvantages: The hard disk capacity required doubles, because a mirrored disk with the same capacity is required.

disk to continue read/write operation.

A read/write operation during data rebuilding will result in lower performance.

Number of hard disks required: 2 (fixed)

52 Hitachi PC VisionBase8450H/R Server

RAID3

Data is striped in bytes into data disks. Array parities are stored in the parity disk.

Ch 3: Installing Optional Devices

Advantages: • Capacity-to-cost ratio is improved as compared with RAID1.

• Data redundancy is ensured by distributing data to several hard disks; therefore, each hard disk can perform read/write operation independently. This type of disk array is useful for transferring large data because data is striped in bytes.

• If a hard disk within the array fails, the lost data is computed based on the array parities, enabling the read/ write operation to continue. By replacing the hard disk, you can rebuild the data without interrupting your current task.

Disadvantages: • This type of disk array is unsuitable for transaction processing (unsuitable for PC server OS processing),

because data is striped in bytes; therefore, the number of accesses increases for transfer of small data.

• Array parities are created during write operation, so efficiency in write operation is not good as RAID0.

• A read/write operation during data rebuilding will result in lower performance.

Number of hard disks required: 3 (min.) to 6 (max.)

Hitachi PC VisionBase8450H/R Server 53

Ch 3: Installing Optional Devices

RAID5

Data, together with array parity, is striped in blocks, extending over all hard disks.

Advantages: • Capacity-to-cost ratio is improved as compared with RAID1.

• Data redundancy is ensured by distributing data to several hard disks; therefore, each hard disk can perform read/write operation independently. This type of disk array is useful for transaction processing because data is striped in block.

• Because array parities are distributed to each hard disk, you can have the advantages of parallel processing through independent access to the hard disks when writing data.

Disadvantages: • Array parities are created during write operation, so performance for write operation is not as high as

RAID0.

• A read/write operation during data rebuilding will result in lower performance.

Number of hard disks required: 3 (min.) to 6 (max.)

Ch 3: Installing Optional Devices

Functions of Disk Array

Degraded mode

The RAID3 or RAID5 disk array enables you to keep on using the array as usual even if one of the hard disks fails. When a disk array operates with one failed hard disk, the operation is referred to as degraded-mode operation. Whena read or write operation is requested, the array disk controller computes data in the failed disk based on the data in the active disks and array parities. However, because of this data computation, processing efficiency decreases as compared with usual situations.

Rebuilding data

In the RAID1, RAID3, or RAID5 disk array, after a failed disk is replaced, the array controller automatically restores data and stores it in the new disk based on the data in the mirrored disk and parity data. This is called “rebuilding data”. You can keep on your task while data is being rebuilt, but processing efficiency decreases, as in degraded mode.

During a degraded-mode operation, an additional hard disk failure will disable the disk array to rebuild data, resulting in loss of all data. Be sure to replace the failed disk immediately and rebuild data.

NOTE: The RAID0 disk array cannot rebuild data because it does not dualize data nor create parities.

Hot plug

When the disk array operates in degraded mode, you need to replace the failed disk as early as possible. However, turning off the system equipment is inconvenient because it is time-consuming and you need to stop the operation.

The function of “hot plug” (also called “hot swap”) is the solution to this problem. With this function, you can replace hard disks while the system equipment is powered.

Hot spare

If the RAID1, RAID3, or RAID5 disk array fails, you need to replace the failed disk in order to recover to the normal status. By installing a reserve disk (with no data) in the disk array, you can have data automatically restored to the reserve disk. This reserve disk is called “hot spare” because it is provided for replacement at any time. The array controller’s function of automatically restoring data to the hot spare is called “standby replacement”.

Building a Disk Array

1. Decide the number of disk arrays to be used and the RAID level, then the number of hard disks to be used and

whether or not to use a reserve disk. Hitachi PC VisionBase8450H/R Server contains six extended storage bays to which you can install a hard disk.

Youcan build a disk array as shown in the following example:

- One-disk-array configuration

Notes on Building Disk Arrays

Hard Disks

The capacity of hard disks used in the same disk array must be the same. If you build two or more disk arrays for the system equipment, the hard disk capacity for each disk array need not

be the same. However, if a reserve disk exists, you need to be aware of some notes on operation. See “Reserve Disk” on page60 for details.

Installing Location for Hard Disks

It is recommended that you mount hard disks for the same disk array in successive extended storage bays for the purpose of system administration. You are also recommended to record configuration of disk arrays.

If reserve disks are mounted, the mounting location will differ; it is best to record disk array configuration each time it is changed.

Hitachi PC VisionBase8450H/R Server 59

Ch 3: Installing Optional Devices

Reserve Disk

The capacity of the reserve disk to be mounted must be the same as that of the hard disks used in the disk array. If you use two disk arrays, note the following at the time of operation. (The disk array configuration shown below

is assumed.)

When there are two or more disk arrays at RAID level 1 or 5

The reserve disk serves as a hot spare for either disk array. Hot spare for hard disks will change the disk array configuration as follows:

• A failure occurs in hard disk A-1 in disk array A.

• A failure occurs in hard disk B-1 in disk array B.

• A failure occurs in hard disk A in disk array A.

As a result of hot spare, the reserve disk is in the same position as for the original configuration, but data disks A-1 and B-1 in the disk array are switched to each other. As can be seen in this example, hard disks comprising a disk array might switch to any position.

It is recommended therefore that you record the hard disk positions each time a failure occurs.

60 Hitachi PC VisionBase8450H/R Server

Ch 3: Installing Optional Devices

When the capacity of the hard disks for disk array A differs from that for disk array B

Depending on the capacity of the reserve disk, the hot spare might not function. Hot spare changes with the capacity of the reserve disk in the following way. It is assumed that the capacity of disk array A is less than that of disk array B (A-x < B-x).

• When the capacity of the reserve disk is the same as that of B-x:

The reserve disk serves as a hot spare in both disk arrays A and B. For hot spare in disk array A (1 and 3 in “When there are two or more disk arrays at RAID level 1 or 5” on

page60), the capacity of the reserve disk is larger than hard disk A-x used in disk array A, therefore the hard disk after the rebuilding will contain unused (unusable and useless) areas.

• The capacity of the reserve disk is the same as that of A-x:

The reserve disk serves as a hot spare in disk array A but not in disk array B. Because the capacity of the reserve disk is less than the hard disk B-x, the data cannot be restored onto the disk.

For that reason, disk array B remains in degraded mode.

To prevent these, you need to use the same capacity for both disk arrays or provide a reserve disk for each disk array. The priority for reserve disks used when a failure occurs is as follows (1 takes priority over 2):

1. Reserve disk with the same capacity as the failed disk

2. Reserve disk whose SCSI ID is smaller

Installing Various Boards

This section explains how to install various types of boards.

Before changing the configuration of the system equipment (such as internal SCSI devices or extended boards), be sure to unplug the power cord, and wait at least 30 seconds. In some rare cases, the setup data might be changed. If so, turn off the system equipment, turn it on, then change the settings on the Setup Menu.

Installing Processors

This system allows multiprocessing of up to four processors. If you use an OS intended for multiprocessing, you can speed up the system by adding processors.

Processors

Processors are of two types, those with 512kB secondary cache and those with 1MB secondary cache. Choose an appropriate type, then install processors starting in processor slot 1.

When you install processors, you also need to install voltage regulating module (VRM; attached to each processor) starting in VRM slot 1.

You need to install a terminator for processor in processor slots with no processor installed.

If you install more than one processor, unify the secondary cache capacity. Make sure you install processors, VRMs, and terminators for processors in the specified positions, to

prevent the system equipment from malfunction.

Installing Processors

This section explains how to install processors in processor slot 2.

NOTE: This section assumes that a processor has already been installed in processor slot 1. Install processors in

processor slots 3 and 4 in the same way. Install terminators for processor in the same way as for processors.

1. Disengage the claw of the cover for processor slot 2, then open the processor slot.

2. Remove the terminator for processor from processor slot 2.

Opening the two levers at the same time will release the terminator from the connector. Then hold and extract the terminator.

3. Holding the processor with its fin facing upward, and keeping the levers open, insert the processor into the slot

until it stops, then close the levers simultaneously.

NOTE: When you install a terminator for processor, you also need to install levers. See “Installing a Lever onto

the Terminator for Processor” on page85 for details.

4. Close the cover.

NOTE: If the claw of the cover cannot be inserted properly, the processor is probably inserted halfway.

Checkwhether the levers are closed properly.
