OVERVIEW
The Smart Array 4250ES Controller is based on new innovations in RAID I/O architecture. This is the second cable-free array controller from Compaq,
providing unparalleled performance and availability in a ProLiant 8000, 7000, or 6000 server with Extended SCSI (ES) PCI slots. Designed specifically
for internal drive support in these ProLiant servers, this controller offers a unique cable-free design--allowing for hot plug, cache coherent fail-over to an
optional second Smart Array 4250ES controller. Note: The ProLiant 7000 and 6000 servers are discontinued.
New record setting RISC processor architecture offering industry-leading controller performance
Hot plug cable-free design, for greater online availability in redundant controller environments
Consistent configuration and management tools for ease of storage deployment and administration
Data compatibility with all Smart Array controllers for simpler, more cost effective upgrades
The Smart Array Advantage
Compaq's innovative design and integration work for the Smart Array family of products offers unmatched customer value. Large-scale use of Smart
Array products creates a much lower cost of ownership than many competitive server storage products. The Compaq Smart Array family brings
unparalleled return on invested dollars due to these product family benefits:
Data Compatibility: Data compatibility among all models of Smart Array Controllers means customers can upgrade their Smart Array products to get to
higher performance, capacity and availability. Unlike competitors' products, successive generations of Smart Array products understand the data format
of other Smart Array controllers.
Note: Certain restrictions and exclusions apply. Consult the Compaq Customer Support Center at 1-800-345-1518 for details.

The Smart Array Advantage (continued)
Consistent Configuration and Management Tools: All Smart Array products utilize a standard set of management and utility software. These tools
consistently lower the cost of ownership by reducing training and technical expertise necessary to install and maintain the Compaq server storage.
Configuration, management and diagnostic software tools include: Array Configuration Utility, Array Diagnostic Utility, Compaq Insight Manager (CIM),
and Compaq SmartStart.
Snapshots and Storage Pools: Compaq delivers the next step towards the Enterprise Network Storage Architecture vision with support for
StorageWorksTMVirtual Replicator by Compaq. With this optional software, users can: instantly create "snapshots" of production data to reduce backup
and restore Windows from hours to minutes; pool storage for quick response to changing storage capacity needs; create "virtual volumes" of up to 1
terabyte and enjoy policy-based automation to simplify system data and storage management.
Pre-Failure Warranty: This means that Compaq Insight Manager not only tells you when a drive is going bad, but allows you to replace failing drives
before they actually fail.
Note: Pre-Failure Warranty is available on all Compaq Prosignia and Compaq ProLiant servers using Compaq Insight Manager 2.1 or higher, and
covers Pentium processors, ECC memory and server hard drives (except the 535 MB Fast-SCSI-2 hard drive) using Compaq IDA, IDA-2,
Compaq SMART SCSI Array Controllers, Compaq SMART-2 Array Controllers or Compaq Smart Array Controllers. Certain restrictions and
exclusions apply. Consult the Compaq Customer Support Center for details.
Server Management
On-Line Capacity Expansion: Simplifies storage management by allowing on-line capacity expansion, eliminating the need to shut down the server
while adding storage.
Logical Drive Capacity Extension: Allows the user to increase the size of existing logical drives.
Array Configuration Utility: Simplifies array configuration and facilitates on-line capacity expansion.
Array Performance Monitor: Monitors key parameters (with Compaq Insight Manager) and provides information for proactive system planning.
Drive & Array Movement: The users can move (detach & attach) drives in any order on the same controller (drive movement) or add a configured drive
array to another controller (array movement), and maintain configuration information. This feature requires the system to be powered down, and there
must not be any failed drives or active spare drives in the array.
High Performance
64-bit Architecture: New 64-bit architecture is designed around the high-performance PowerPC Super-scalar RISC processor with a 64-bit data path.
Intelligent Array Engines: Processing tasks are divided between two engines. Working simultaneously, one engine generates fault tolerance
information and manages data flow, while the other prepares and sorts array storage commands.
3 Channels: Three SCSI channels provide up to 1.528 TB of high-availability fault tolerant storage using the 72.8-GB Wide Ultra3 Hard Drives.
Enhanced Array Accelerator: 64-MB ECC-protected and battery-backed removable read/write cache module maximizes I/O performance without
sacrificing data integrity. Prediction of sequential operations and retrieval of data prior to a request further enhances performance.
Note: 56 MB useable for Read/Write cache, 8 MB used for transfer buffer and scripts memory.
Data Distribution/Accessibility: Data is distributed across multiple drives (up to 21), optimizing drive efficiency and performance. Multiple commands
and requests for information are processed simultaneously across drives with Tagged Command Queuing.
Higher Availability
Online storage management tools saves you training and administration costs: Online RAID Level Migration, Online Capacity Expansion, Logical Drive
Capacity Extension, Global Online Spares, Pre-Failure Warranty.
Note: Pre-Failure Warranty is available on all Compaq Prosignia and Compaq ProLiant servers using Compaq Insight Manager 2.1 or higher, and
covers Pentium processors, ECC memory and server hard drives (except the 535 MB Fast-SCSI-2 hard drive) using Compaq IDA, IDA-2,
Compaq SMART SCSI Array Controllers, Compaq SMART-2 Array Controllers or Compaq Smart Array Controllers. Certain restrictions and
exclusions apply. Consult the Compaq Customer Support Center for details.
Fail-over Controller Redundancy: Supports redundant controller boards for higher data availability. You can Hot Plug a redundant SA-4250ES
controller without bringing down the server.
Fault Tolerance
Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including:
Distributed Data Guarding (RAID 5): Allocates parity data across multiple drives and allows simultaneous write operations.
Data Guarding (RAID 4): Writes parity data to a single, dedicated parity drive.
Drive Mirroring (RAID 1, 1+0): Allocates half of the drive array to data and the other half to mirrored data, providing two copies of every file.

Fault Recovery
Minimizes downtime, data and facilitates a quick recovery from component failures.
On-Line Spares: Up to four spare drives can be installed prior to drive failure. If a failure occurs, recovery begins with a Global On-Line Spare and data
is reconstructed automatically.
Array Accelerator: Onboard battery backup of cached memory protects data in the event of a power, controller or server hardware failure. This
daughter board is uniquely removable from the array in the unlikely event of a controller failure--saving critical user data for up to 4 days.
Hot Pluggable Drive Support
Hard disk drives can be removed or added without powering down the server.
Storage Capacity
Three SCSI channels allows support for up to twenty-one, 1 in (2.54 cm) drives on a single controller in the ProLiant 8000 server, and up to twelve, 1.6 in
(4.06 cm) drives and eighteen, 1 in (2.54 cm) drives in the ProLiant 6000 and 7000 servers.
Maximum internal capacity for the ProLiant 8000 server is twenty-one, 1 in (2.54 cm) 72.8-GB drives, resulting in 1.528 TB of storage (21 x 72.8 GB 1"
Wide Ultra3 drives).
SOFTWARE COMPONENTS
Compaq Smart Array software makes configuration, management, and trouble shooting a breeze. Compaq Smart Array products utilize a single,
consistent set of utility software for storage and RAID management. This consistency across the Smart Array product line reduces the cost of ownership
by reducing training and technical expertise necessary to install and maintain your Compaq server storage solution.
