PCI Express - Serial ATA II RAID Adapter

The eXpeRAID® PCI Express™ to SATA2

RAID adapters offer superior performance and

comprehensive RAID functions for Windows,

Linux, and Mac platforms with user-friendly

Java-based GUI, RAIDGuard™ X. Built upon

the latest Intel XScale® Technology-based I/O

processor, the eXpeRAID adapters support

RAID 6 for enterprise-class data protection.

Supporting up to 16 SATA2 disk drives, the

eXpeRAID adapters are well suited for various

applications, such as video editing, digital

surveillance, file servers, and shared storage.

The eXpeRAID adapters deliver excellent

performance with intelligent I/O processing

and elaborated RAID algorithms. The

controller can guarantee timely I/O response

by bypassing slow disk drives and delivering

requested data by fast online data rebuild. It

streamlines the data transfer and sustains a

stable throughput, so the controllers can

smoothly handle heavy-loading and time-

critical applications. It also provides

configurable optimization policies to support

different workload.

Featuring reliable RAID technologies, the

eXpeRAID adapters protect data against not

only disk drive failure but also bad sectors by

online recovery and reallocation. In addition to

online disk scrubbing for fixing the bad

sectors, the controller also supports online

data and parity refresh to proactively prevent

data loss caused by media aging.

The eXpeRAID adapters support snapshot, by

which users can instantaneously create data

images at different points of time. After a

snapshot of LUN is created, the original LUN

can still serve I/O requests normally, while the

snapshot can be exported as an independent

LUN for other hosts and applications. The

snapshot helps to implement zero-down time

backup scenario, and speed up backup

operations. Users can also rely on snapshot

for fast data restore or data mining.

To support dynamics in ever-changing IT

environments, the eXpeRAID adapters provide

not only flexible RAID configurations but also

extensive utilities to online change the RAID

configurations. Users can easily expand the

RAID capacity and repartition the RAID. It is

also allowed to conduct RAID migration virtually

from any to any.

The innovative on-the-fly RAID initialization

makes the RAID storage instantly available. The

controller initializes the data areas hit by the

host I/O access and maintains a table to track

these areas. The subsequent I/O access and

the background initialization task needs not to

initialize these areas. This efficiently speeds up

the initialization process and improves the

performance during the initialization.

The eXpeRAID adapters satisfy users of

different backgrounds by offering a variety of

management interfaces, including EFI CLI,

BIOS UI, LCD panel, and Java-based GUI --

RAIDGuard™ X. Users can quickly set up RAID

configurations within minutes, and remotely

manage multiple RAID adapters from single

console by the GUI. Together with friendly event

browsing and email notification, RAIDGuard™ X

can support a newbie to effortlessly enjoy the

high-performance and reliable RAID storage as

well as reduce the support cost of system

integrators.

In addition to commonly-used platforms, the

eXpeRAID adapters also offer future-proof

interoperability. It supports the next-generation

BIOS, EFI, which is also a necessity on IA-

based Mac machines. It also supports Windows

Storport driver, which enhances the

performance and reliability on Windows

platforms. Meanwhile, the GUI, RAIDGuard™ X,

based on Java, can run on virtually all platforms.
