Overview of Array Accelerator Features

The array accelerator is a high performance, battery-backed, 100-MHz SDRAM

DIMM cache module.

Array controllers use cache to store read data from the hard drives. The system can

later access this read data. The controller firmware uses the read-ahead and most

recently used caching algorithms.

Array controllers also use cache to complete drive write operations more quickly.

This use of the cache has further performance benefits:

•

If the system requires data that still resides in write cache, the controller delivers this data from the cache. This process is quicker than delivering the data from a drive.

•

If the system writes new data to the same location, the controller overwrites the cache contents. This eliminates a drive write operation.

•

If the system performs a RAID 1 procedure, the controller gets mirrored data from the cache instead of from host memory.

•

If the system performs a RAID 5 procedure, the write cache collects enough data blocks from several write accesses to carry out a full stripe write to the hard drives. This operation eliminates the need to calculate and update parity information each time that a data block is written to the drive.

With a battery-backed cache available, the array controller can complete the

following operations more rapidly:

•

Array capacity expansion—the expansion of a logical drive volume to include more hard drives

•

Stripe size migration—the adjustment of the size of data blocks within a stripe, done to improve performance

•

RAID level migration—the adjustment of RAID level to improve the fault tolerance of the array

HP Smart Array 5300 Controller User Guide 1-5

Board Components and Features

For each of these operations, data has to be reorganized among hard drives, and must be saved to non-volatile storage during the operation. (For further details of these operations, refer to Chapter 6, Appendix D, and Appendix E.) Without batterybacked cache, the data can only be stored at empty locations within the drive array, so these operations cannot occur at all if the array is full.

If the array controller or server fails before cached data can be stored on the array, the array accelerator and its integrated batteries may be removed from one array controller and installed on another controller of the same type. Any data in the array accelerator that has not been written to the hard drive will be transferred to the other array controller.

Other features of the array accelerator include:

•

Cache capacity of 96-MB or 224-MB (32 MB of the cache is used for transfer

buffer)

•

Adjustable read/write ratio (usually set during array configuration as described in

Chapter 6, “Configuring an Array,” but can be changed at any time)

•

Error checking and correcting (ECC) memory, providing single-bit data

correction

Sometimes, the Automatic Performance Tuning feature disables the array accelerator. You can also disable the array accelerator manually through the Array Configuration Utility (refer to Chapter 6, “Configuring an Array,” for details).

Batteries

The array accelerator cache has two rechargeable and replaceable NiMH battery packs. If the array accelerator is removed from the array controller, the battery packs maintain any cached data on the array accelerator for up to four continuous days.

1-6 HP Smart Array 5300 Controller User Guide

Board Components and Features

Figure 1-5: Battery packs

This data protection (and the time limit) also applies if an equipment failure or power

outage occurs. When power is restored to the system, an initialization process writes

the preserved data to the hard drives.

The batteries are continuously recharged using a trickle-charging process whenever

the system power is on. Under normal operating conditions, a battery pack lasts for

three years before replacement is necessary.

IMPORTANT: The batteries on a new array controller may have a low charge when the

controller board is first installed. In this case, a Power-On Self-Test (POST) message is

displayed when the server is powered up, indicating that the array accelerator is temporarily

disabled. No action is required on your part, since the internal circuitry automatically recharges

the batteries and enables the cache. The recharge process takes less than four hours. The

array controller will function properly during this time, although without the performance

advantage of the array accelerator. When the batteries are charged to an acceptable capacity,

the array accelerator is automatically enabled.

For battery replacement instructions, refer to Chapter 8, “Upgrading and Replacing

Options.”

HP Smart Array 5300 Controller User Guide 1-7

Board Components and Features

PCI System Interface

Smart Array 5300 controllers interface to the server through a high-performance 64-bit PCI bus that:

•

Runs at 66 MHz

•

Provides a high-speed path (up to 528 MB/s) between the system board and the

controller

•

Includes two parity protection signals

The Smart Array 5300 Controller is a PCI Bus Master device conforming to Rev. 2.2 of the PCI Local Bus Specification. As a bus master device, it takes control of the PCI bus during high-speed transfers, freeing the system processor to handle application processing or other types of tasks.

For maximum performance, HP recommends that you use only 66-MHz devices on any given 66-MHz PCI bus. Combining 66-MHz and 33-MHz devices on a PCI bus will decrease the overall bandwidth to 33-MHz speeds.

SCSI Support

The Smart Array 5300 Controller supports drives that conform to Wide Ultra3 and Wide Ultra2 standards. Although Wide Ultra2 devices operate at a different maximum speed from Wide Ultra3 devices, operating speeds are unaffected if they are connected to the same SCSI bus because they both use low voltage differential (LVD) signaling.

Fault Management Features

The array controller and the network operating system support several fault management and data reliability features that minimize the impact of hard drive defects on your system.

1-8 HP Smart Array 5300 Controller User Guide

Board Components and Features

• Auto-Reliability Monitoring (ARM) is a background process that scans hard

drives for bad sectors in fault-tolerant logical drives. ARM also verifies the consistency of parity data in logical drives that are using RAID 5 or RAID ADG. This process assures that you can recover all data successfully if a drive failure occurs in the future. ARM operates only when you select a fault-tolerant configuration (RAID 1 or higher).

•

Dynamic sector repair by the controller automatically remaps any sectors that have media faults (detected either during normal operation or by auto reliability monitoring).

•

S.M.A.R.T. is an industry-standard diagnostic and failure-prediction feature of hard drives, developed in collaboration with the hard drive industry. It monitors several factors that can be used to predict imminent hard drive failure due to mechanical causes. Such factors include the condition of the read/write head, the seek error rate, and the spin-up time. When a threshold value is exceeded for one of these factors, the drive sends an alert that failure is imminent. Thus, the user can back up data and replace the drive before drive failure occurs.

NOTE: An online spare does not become active and start rebuilding when the imminent failure alert is sent, because the degraded drive has not actually failed yet and is still online. The online spare is activated only after a drive in the array has failed.

•

Drive failure alert features cause an alert message to be displayed on the system monitor when drive failure occurs. Different server models use different messages for different situations. These messages are described in your server documentation.

•

Interim data recovery occurs if a drive fails in fault-tolerant configurations (RAID 1 or higher). In this situation, the system will still process I/O requests, but at a reduced performance level. Replace the failed drive as soon as possible to restore performance and full fault tolerance for that logical drive. For example, in a RAID 5 configuration, if another hard drive fails before data has been rebuilt, the logical volume will fail and data will be lost. For more information about recovering from drive failure, refer to Appendix E, “Hard Drive Installation and Replacement.”

•

POST or the Array Diagnostics Utility will also reveal imminent drive failure.

HP Smart Array 5300 Controller User Guide 1-9

Board Components and Features

• Recovery ROM is a redundancy feature that ensures continuous system

availability by providing a backup ROM. This feature protects against corruption

of a ROM image (caused, for example, by power fluctuation during ROM

upgrade). If corruption occurs, the server automatically restarts using the

remaining good copy of the ROM image.

When you upgrade the ROM, the inactive image (the one not being used by the

system) is upgraded. There is not normally any noticeable difference in

operation. When you use Recovery ROM for the first time, however, both ROM

images are upgraded, causing a boot delay of about 60 seconds.

Other options, such as Insight Manager, provide additional drive failure features. Refer to your authorized reseller for more information about these products.

1-10 HP Smart Array 5300 Controller User Guide

Installation Overview

The details of the steps required to install the controller depend on the server model

and whether the server is a new or existing one. The following flowcharts summarize

the installation procedures for the most common scenarios.

Procedure for a New, Autoconfigurable System

Some new HP ProLiant server models self-configure when they are powered up for

the first time. During the autoconfiguration process, the system language is set to

English by default, and Microsoft Windows 2000 is selected as the default operating

system. (However, you must still install the operating system. This is done later in

the overall controller installation procedure.) If you want to use a different system

language or operating system, you can press the F9 key at any time. This action

opens RBSU, which allows you to manually configure the server.

Also, if the server has fewer than seven physical drives installed, ORCA

automatically configures the drives into an array, builds a logical drive, and sets a

RAID level suitable for the number of drives.

To determine if your server is autoconfigurable, refer to the server-specific setup and

installation guide.

IMPORTANT: Do not power up the server until the hardware configuration is satisfactory, as

described in the procedure given in this section.

HP Smart Array 5300 Controller User Guide 2-5

Preparing the Server

Before installing the controller in the server, back up all data. This step is mandatory

if you are moving non-arrayed SCSI drives to a Smart Array controller, because data

is not preserved during a move between array controllers and non-array controllers.

WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with your computer before attempting the installation.

Many computers are capable of producing energy levels that are considered hazardous. These computers are intended to be serviced by qualified personnel trained to deal with those hazards. Do not remove enclosures or attempt to bypass any interlocks that may be provided for the purpose of removing these hazardous conditions.

Installing the Hardware

If your server supports hot-pluggable devices, go directly to the section, “Installing

the Smart Array Controller.”

To prepare a server that does not support hot-pluggable devices:

1. Close all applications.

2. Power down the server.

CAUTION: In systems using external data storage, be sure that the server is the first unit powered down and the last unit to be powered back up. Doing this ensures that the system will not erroneously mark the drives as “failed.”

3. Power down any peripheral devices that are attached to the server.

HP Smart Array 5300 Controller User Guide 3-1

Installing the Hardware

4. Unplug the AC power cord from the outlet, and then from the server.

IMPORTANT: If you will be replacing an existing Smart Array controller with a Smart

Array 5300 controller, see the “External Cabling for HP Servers” section to determine the

external cabling requirements.

5. Disconnect any peripheral devices from the server.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components and hot-plug hard drives to cool before touching them.

CAUTION: Electrostatic discharge (ESD) can damage electronic components.

Be sure that you are properly grounded before continuing the installation procedure. Refer to Appendix B, “Electrostatic Discharge,” for ESD information.

Installing the Smart Array Controller

1. Remove or open the access panel.

2. Select an available 66-MHz PCI slot. Slots that use a 64-bit interface may

provide higher performance.

NOTE: In IPF servers, the ID number of the slot in which you insert the controller

determines the boot controller order. Follow the recommendations in the server-specific

documentation to obtain the required controller order.

3. Remove the slot cover or open the hot-plug latch. Save the retaining screw, if one

is present.

4. Slide the controller board along the slot alignment guide.

3-2 HP Smart Array 5300 Controller User Guide

Installing the Hardware

Figure 3-1: Installing a Smart Array 5300 Controller

NOTE: Your server may look slightly different from the one illustrated.

5. Press the controller board firmly into the slot so that the contacts on the board edge are properly seated in the system board connector.

6. Secure the board in place with the hot-plug latch or retaining screw.

7. Continue by following the instructions given in “Connecting the Cables.”

Connecting the Cables

Each port on the controller supports up to 14 drives. Ports 1 and 2 each have two SCSI connectors, one for external storage units and one for internal hard drives in the server. The two connectors for a given port cannot be used simultaneously. Ports 3 and 4 (present on the 5304 model, and also on the 5302 model with an attached 2- to 4-channel adapter) are only for external storage units.

Peripherals attached to any of the connectors must have a unique SCSI ID value in the range of 0 to 15 (except ID 7, which is reserved for controller use). The SCSI ID value determines the priority given to the device when it attempts to use the SCSI bus.

HP Smart Array 5300 Controller User Guide 3-3

Installing the Hardware

On HP and Compaq-branded products that support hot-pluggable drives, the SCSI IDs for peripherals are automatically set. For non-hot-pluggable devices, the IDs must be set manually by using switches or jumpers on the device itself.

IMPORTANT: When replacing an existing Smart Array controller with a Smart Array 5300 controller without reconfiguring the arrays, all of the drives should be connected exactly as they were on the old controller (port 1 to port 1, controller 1 to controller 1, and so on).

SCSI buses require termination on both ends to prevent signal degradation. In HP and ProLiant servers and IPF servers, however, the controller, SCSI cable, and backplane already provide this termination.

Internal Cabling for HP Servers

1. If the device is not hot pluggable, power down the system.

2. Install drives in the removable media bays on the server. Drives that are to be

grouped in the same array should have the same capacity.

For detailed drive installation instructions, consult the documentation that accompanied your drives.

The exact procedure from this point depends upon whether the device is hot pluggable.

— If the drives are hot pluggable, go to step 3.

— If the drives are not hot pluggable, go to step 4.

3. Attach the internal point-to-point SCSI cable (provided with your server) from an internal port of the controller to the hot-plug drive cage.

For duplex drive cage options, use both internal ports.

The hot-pluggable drives are now ready to use.

4. For each SCSI bus, manually set the SCSI ID on each drive to a unique value in the range of 0 to 15, except 7 (which is reserved for controller use). For detailed instructions, consult the documentation that is provided with the drive.

5. Attach the multi-device SCSI cable from the internal port 1 or port 2 of the Smart Array controller to the non-hot-pluggable hard drives.

6. Replace the access panel and secure it with the thumbscrews, as required.
