With the following components, your storage capacity and performance can be scaled to new levels:

HP StorageWorks Modular

Smart Array 1000

The 4U cabinet houses up to fourteen 1" Universal hot pluggable Ultra2, Ultra3, and/or Ultra320 drives. Each

MSA1000 includes the following standard components: (1) MSA1000 Controller, (1) MSA Fibre Channel I/O Module

with a single SFP, dual hot pluggable fans/power supplies and power cables, documentation and a support software

CD.

The modular design of the MSA1000 makes it possible to add redundant controllers, redundant single port Fibre

Channel I/O Modules, 3-port hub, or embedded fabric switch and storage expansion enclosures. Additional storage

enclosures may be added without power cycling the MSA1000.

MSA1000 Controller

The MSA1000 Controller is an integrated RAID controller with an LCD/LED status display and 256 MB read/write

battery-backed cache (expandable to 512 MB per controller). One MSA1000 Controller is included with the MSA1000;

a redundant MSA1000 Controller is an option. Purchase of Secure Path software is a requirement if a second

controller is chosen.

Host based configuration via ACU (OS dependent)

Optionally configurable with Command Line Interface (CLI)

Remote configuration and monitoring via ACU (offline and remote) & Insight

Manager (OS dependent)

Management Features

Selective Storage Presentation

: allows multiple hosts to access a single

MSA1000 storage system. Host access can be defined all the way down to a

logical volume level.

Online RAID Level Migration

: allows for online post-configuration change to

RAID level without destroying data or volume information.

Online Capacity Expansion

: : lets you add storage to an operational

MSA1000-reducing expensive server downtime.

Global Online Spare

: reduces the risk of data loss by facilitating automatic

rebuilds after a drive failure.

Fault Tolerance

Several fault tolerant configurations which keep data available and servers running

while drives are being replaced are supported including:

Advanced Data Guarding (RAID ADG): Allocates the equivalent of two parity

drives across multiple drives and allows simultaneous write operations.

Distributed Data Guarding (RAID 5): Allocates parity data across multiple drives

and allows simultaneous write operations.

Drive Mirroring (RAID 1, (1+0 Striped Mirroring)): 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, reconstructs data, and facilitates a quick recovery from drive

failure:

Online Spares: If a failure occurs, recovery begins with an online spare and

data is reconstructed automatically. Multiple online spares can be assigned per

array and used across multiple arrays. It is also possible to assign different

online spares across different arrays.

Array Accelerator: Onboard, battery-backed cache memory protects data in

the event of a power failure. In the unlikely event of a controller failure, the

battery-backed cache will save critical user data for up to three days.
