It will handle up to 14 Wide Ultra SCSI-3, and all lower SCSI, drives. The SMART-2/P Array Controller (Spare part #194754-001) Rev. B, with latest updated bios (v4.44) from Compaq, combines configuration flexibility and intelligent storage management to ensure continuous high-performance. The SMART-2 Array Controller is based on an Intelligent I/O Architecture which enables truly breakthrough capabilities for managing high performance storage. on-line Capacity Expansion Simplifies storage management by allowing on-line addition of more storage in RAID configurations, eliminating the need to back-up, reconfigure, and restore Array Configuration. Host Interface: 32-bit PCI bus-master technology delivers information at rates up to 133 MB/s.

This card has Two Channels and will provide over 300 GB of high-availability storage. The Enhanced Array Accelerator: 4-MB ECC-protected and battery-backed removable read/write cache, maximizes I/O performance without sacrificing data integrity.

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, designated drive.

Mirroring (RAID 1): Allocates half of the drive array to mirroring the other half, providing two copies of every file. It also has Hot-Pluggable Drive Support, allowing drives to be removed or added without powering down the System.

With the SMART-2 Controller external storage capacity is maximized on Compaq servers. Server Support for SMART-2 Controllers is supported on following systems: ProLiant 800, 850, 850R, 1200, 1500, 1600, 1850R, 2500, 3000, 5000, 5500, 6000, 6500, and 7000 (any PCI Compaq Server). Simultaneous Drive Transfer Channels: Two, Total Channel Transfer Rate: 40 MB/s (20 MB/s per channel, Software Upgradeable Firmware, Cache: 4-MB Array Accelerator (ECC protected), removable with battery backup, Logical Drives Supported: 32.

On-Line Capacity Expansion: Simplifies storage management by allowing on-line addition of more storage in RAID configurations, eliminating the need to back-up, reconfigure, and restore.

Array Configuration Utility: Graphical user interface, which simplifies array configuration and facilitates on-line capacity expansion.

Array Performance Monitor: Monitors key parameters and provides information for proactive system planning.
