The Smart Array
Advantage

HP's innovative design and integration work within the Smart Array family of products creates
customer value that is unmatched in the industry. Use of Smart Array products across multiple
applications results in a much lower Total Cost of Ownership (TCO) than any other server storage
RAID product. The HP Smart Array family brings an unparalleled return on investment.

Data Compatibility
Consistent Configuration and Management Tools
Universal Hard Drive
Pre-Failure Warranty

Data Compatibility

Data Compatibility with past and future generations of Serial Smart Array controllers allows for
simple and easy upgrades any time needs for higher performance, capacity, and availability
increase.

Consistent
Configuration and
Management Tools

All Smart Array products utilize a standard set of management and utility software. These tools
minimize Total Cost of Ownership (TCO) by reducing training requirements and technical expertise
necessary to install and maintain HP server storage.

Universal Hard Drive

A universal hard drive is used across multiple HP ProLiant servers, disk enclosures and storage
systems. With compatibility across many enterprise platforms, you are free to deploy and re­deploy these drives to quickly deliver increased storage capacity, migrate data between systems,
and easily manage spare drives.

Pre-Failure Warranty

Pre-Failure Warranty means Systems Insight Manager not only reports when a drive is going to fail
but allows replacement of failing drives prior to actual failure. For complete details, consult the HP
Support Center or refer to your HP Server documentation.

Key Features

The SA-P400 controller supports up to 18 drives. The SA-P400i supports up to 6 drives
depending on the server implementation.
Seamless upgrades from past generations and upgrades to next generation HP high
performance and high capacity Serial Attached SCSI Smart Array controllers.
3G SAS technology delivers high performance and data bandwidth up to 300 MB/s per
physical link and contains full compatibility with 1.5G SATA technology.
x8 2.5G PCI Express host interface technology delivers high performance and data
bandwidth up to 2 GB/s maximum bandwidth.
Modular, easy-to-upgrade design lets you optimize performance by upgrading from 40-bit
256MB cache to 72-bit 512MB battery-backed write cache (BBWC).
Addition of the battery backed cache upgrade enables BBWC, RAID 6 with ADG, array
expansion, logical drive extension, RAID migration, and stripe size migration.
Mix-and-match SAS and SATA hard drives, lets you deploy drive technology as needed to fit
your computing environment.
Software consistency among all Smart Array family products: Array Configuration Utility
(ACU), Option ROM Configuration for Arrays (ORCA), Systems Insight Manager, Array
Diagnostic Utility (ADU) and SmartStart.
Support for up to 2TB in a single logical drive.
Low-profile PCI Express form factor - ships with a full size bracket for deployment in either a
low-profile or full sized slot.

Fault Prevention

The following features offer detection of possible failures before they occur, allowing preventive
action to be taken:

S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at HP
detects possible hard disk failure before it occurs, allowing replacement of the hard drive
before a real failure occurs.
Drive Parameter Tracking monitors drive operational parameters, predicting failure and
notifying the administrator.
Dynamic Sector Repairing continually performs background surface scans on the hard disk
drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure
preventative maintenance.
