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
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.

MSA1000 Controller
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
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 threeand 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.

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.

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.

3.As illustrated in Figure 3, unlatch the controller cover clips 1 on the rear of 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 HewlettPackard 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.
