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

Codename: SilverHammer Part Number: 135606-004 Last Saved On: 7/22/02 11:09 AM
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 7, Appendix D, and Appendix E.) Without battery-
backed 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 7, 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 7 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.

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 1794 is
displayed when the server is powered up (refer to Appendix G), 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 9.

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, Compaq 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.
