Battery-Backed Cache Module Overview

The battery-backed cache module is a high-performance, 100-MHz SDRAM DIMM read/write cache that increases performance in database and fault-tolerant configurations.

Caching Functions

To enable faster data access from disk storage, the cache module performs two types of caching:

• Posted-write caching—the controller writes user data in the cache memory on the module rather than directly to the drives. Later, when the system is idle, 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 the cached data, the controller immediately loads the data into system memory, avoiding the latency of a disk access.

Batteries

The cache module has two rechargeable and replaceable NiMH battery packs that protect cached data during equipment failure or power outage:

• Up to 3 days protection for 256-MB cache DIMMs

• Up to for 4 days protection for 128-MB cache DIMMs

Under normal operating conditions, the battery packs should operate for 3 years before replacement is necessary. The batteries recharge continuously when the system is powered on.

NOTE: Temperature, age, and cache size may affect battery life.

The batteries also preserve data when you remove the cache module from the controller. After you reinstall the cache module, and power is restored, the initialization process writes the preserved data to the array. This feature is important for data stored in the posted-write cache, but not yet written to an array.

HP StorageWorks Modular Smart Array 500 System User Guide 1-17

To install an MSA500 system:

1. Unpack the system. Refer to “Shipping Container Contents” in this chapter.

2. Install the system in a rack. Refer to “Installing the System into the Rack” in

this chapter.

3. Install hardware options, if applicable. Refer to procedures in Chapter 3, “Hardware Options Installation.”

4. Connect SCSI cables and power cords. Refer to “System Cabling” in this chapter.

5. Power up the system. Refer to “System Power Up” in this chapter.

6. Configure arrays. Refer to Chapter 4, “Configuration and Utilities.”

Optimum Environment

Installation and Operation

When installing the MSA500 system in a rack, select a location that meets the environmental standards described in Appendix E, “Specifications.”

For adequate airflow, use appropriate high-airflow inserts in rack cabinet doors and observe industry standard practices for adequate spacing between racks or rows of racks.

HP StorageWorks Modular Smart Array 500 System User Guide 2-1

Installation and Operation

Warnings

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

• The leveling jacks are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizing feet are attached to the rack if it is a single-rack installation.

• The racks are coupled together in multiple-rack installations.

• Only one component is extended at a time. A rack may become unstable if

more than one component is extended for any reason.

WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack:

• At least two people are needed to safely unload the rack from the pallet. An

empty 42U rack can weigh as much as 115 kg (253 lb), can stand more than

2.1 m (7 ft) tall, and may become unstable when being moved on its casters.

• Never stand in front of the rack when it is rolling down the ramp from the

pallet. Always handle the rack from both sides.

Shipping Contents

Unpack the system shipping carton and locate the materials and documentation necessary for installing the system. All the rack mounting hardware necessary for installing the system into the rack is included with the rack or the system.
