MSA1000 Controller
Components
The MSA1000 Controller is a drive array controller specifically designed for
installation in the MSA1000. The MSA1000 comes equipped with one MSA1000
Controller installed. An additional controller for redundancy can be purchased
separately.
To ensure uninterrupted service, two copies of the controller firmware are stored
in Read Only Memory (ROM) on the controller. See the “Recovery ROM” and
“ROM Cloning” sections for more information.
Additional information about the following topics is included in this section:
■ MSA1000 Controller Display
■ Array Accelerator (Battery-backed Cache)

MSA1000 Controller Display
Each array controller in an MSA1000 contains an integrated Liquid Crystal
Display (LCD). This module is used for displaying informational and error
messages, showing the status of the module, and for providing user input when
required. Traditional Power-On Self-Test (POST) messages issued by PCI-based
array controllers have been combined with runtime event notification messages to
create a new set of controller display messages.

Array Accelerator (Battery-backed Cache)
The Array Accelerator is a high-performance, upgradeable 256-MB SDRAM
DIMM read/write battery-backed cache that can increase performance in database
and fault-tolerant configurations. It performs both protected posted-write caching
and read-ahead caching, allowing data to be accessed much faster than from disk
storage.
In protected posted-write caching, data is written to the cache memory on the
Array Accelerator rather than directly to the drives. Later, when the MSA1000
storage system is idle, the controller writes the cached data to the drive array.
The read-ahead cache detects sequential accesses to the array, reads ahead data,
and stores the data in the cache until the next read access arrives. If the data is of a
sequential nature, the data can be loaded immediately into memory, avoiding the
latency of a disk access.
If the MSA1000 Controller fails before cached data is stored on the disk, the
Array Accelerator and its integrated batteries may be removed from one
MSA1000 Controller and installed on a replacement controller. Any data in the
Array Accelerator that has not been written to the hard drive will be transferred to
the replacement MSA1000 Controller.
Array Accelerator Features
MSA1000 Controller
Other features of the Array Accelerator:
■ Mounted on a removable daughterboard (allows stored data to be moved to
another controller if the original controller fails)
■ Backed up with replaceable batteries
■ Upgradable to 512 MB (256 MB per controller)
■ Adjustable read/write ratio - usually set during array configuration but can be
changed at any time
■ 16-bit Error Checking and Correcting (ECC) SDRAM memory
ECC detects and corrects all single-bit memory errors. It also detects all
two-bit memory errors in any position, and most three- and four-bit memory
errors in a single SDRAM. With ECC, an entire memory chip can also fail
without data loss. This provides a high level of data integrity by ensuring the
correction of common memory errors without affecting performance.
13MSA1000 Controller User Guide
MSA1000 Controller
Array Accelerator Batteries
The Array Accelerator has two rechargeable and replaceable Nickel Metal
Hydride (NiMH) battery packs. Under normal operating conditions, these should
last for three years before replacement is necessary. They are continuously
recharged via a “trickle” charging process whenever the MSA1000 storage system
is powered on.
The battery packs protect data on the Array Accelerator against equipment failure
or power outage for up to four continuous days.
Note: Temperature, age, and cache size may affect battery life.
This also applies if the Array Accelerator is removed from the MSA1000
Controller. When power is restored to the MSA1000 storage system, an
initialization process writes the preserved data to the disk drives. This is
particularly important for data that has been cached by a posted-write operation,
but has not yet been written to the hard drives.
Note: The batteries on a new MSA1000 Controller may be discharged when the
board is first installed. In this case, a Power-On Self-Test (POST) message will be
displayed on the controller display panel when the controller is powered on, indicating
that the Array Accelerator is temporarily disabled. No action is required on your part,
since the internal circuitry will automatically recharge the batteries. Recharging the
batteries can take up to 4 hours. The MSA1000 Controller will function properly during
this time, although without the performance advantage of the Array Accelerator. When
the batteries are charged to 90 percent of their capacity, the Array Accelerator is
automatically enabled.
Depending on the status of the array accelerator, including a low battery charge,
informational or error messages may be displayed on the controller’s LCD panel.
For a listing of cache module LCD messages, see the definitions for LCD
messages 60 through 79 in the “Controller Display Messages” chapter.
14 MSA1000 Controller User Guide
Replacing the MSA1000 Controller Cache
Caution: It is important to follow these instructions when replacing
components in the MSA1000. If the procedure is done improperly, it is
possible to lose data or damage equipment. Refer to Appendix B,
“Electrostatic Discharge,” for important information on using the proper
procedures.
Note: If your system is equipped with a single controller, and you must replace the
controller cache, you must power down the system first. If your system is equipped with
two controllers, and you want to replace a failed cache module with another of the
same size, you can replace the module while the system is running. If your system is
equipped with two controllers, and you are replacing the cache module with a module
of a different size, you must power down the system first, and then change the cache
module on both controllers at the same time.
1. Press the controller’s thumb latch and pull the latch handle towards you 1.
See Figure 2.
2. Remove the MSA1000 Controller by pulling it straight out of the chassis 2.

the controller and then raise the cover 2.
Note: The controller in Figure 3 has been rotated so the side and rear of the controller
are visible.
4. Simultaneously unlatch the clips that are holding the MSA1000 Controller
cache in place 3.
5. Carefully pull the cache away from the controller board 4.

Replacing the Controller Cache Battery Pack
WARNING: There is a risk of explosion, fire, or personal injury if the battery
pack is replaced incorrectly or mistreated. To reduce the risk:
■ Do not attempt to recharge the battery outside of the controller.
■ Do not expose to water, or to temperatures higher than 60°C.
■ Do not abuse, disassemble, crush, puncture, short external contacts, or
dispose of in fire or water.
■ Replace only with the spare designated for this product.
■ Array Accelerator battery disposal should comply with local regulations.
Alternatively, return them by established parts return methods to
Hewlett- Packard Corporation for disposal.
Caution: It is important to follow these instructions when replacing
components in the MSA1000. If the procedure is done improperly, it is
possible to lose data or damage equipment. Refer to the “Electrostatic
Discharge” appendix for important information on using the proper
procedures.
To remove the old NiMH battery pack:
1. Remove the MSA1000 Controller Cache, as instructed in the previous
section, “Replacing the MSA1000 Controller Cache.”
2. Push down on the bottom clip of the battery pack, attached near the lower
corner of the Array Accelerator.
See Figure 6 for an illustration.
