ATTO Technology Releases Xtend SAN v3.0 iSCSI Initiator for Mac OS X

Version 3.0 Introduces Major New Features for Mac OS X iSCSI Users

Amherst, NY (September 18, 2007) – ATTO Technology, Inc., a global leader
of storage connectivity and infrastructure solutions for data-intensive
computing environments, announced today that it has released a major
upgrade to its Xtend SAN iSCSI Initiator for Mac OS X, Version 3.0. Xtend
SAN software allows Mac users to garner the benefits of Internet SCSI
(iSCSI), one of the fastest growing storage networking protocols today.
With iSCSI, users can take advantage of existing Ethernet expertise and
equipment to benefit from a Storage Area Network (SAN), while avoiding the
cost and complexity associated with Fibre Channel. By installing Xtend SAN
on an OS X workstation, users can benefit from such key iSCSI applications
such as collaborative digital video/audio workflows, laptop connectivity to
SANs, and remote backups. Since version 3.0 of Xtend SAN has been tested
against products from leading iSCSI manufacturers, users can be assured
that Xtend SAN provides a high level of interoperability with various iSCSI

Version 3.0 of Xtend SAN provides new features to aid Macintosh users
operating in iSCSI environments including:

* Challenge-Handshake Authentication Protocol (CHAP) Support — CHAP is the
primary authentication mechanism for iSCSI SANs. The implementation of CHAP
in Xtend SAN enhances security of iSCSI SANs by validating the identity of
remote clients.

* Internet Storage Name Service (iSNS) Support — iSNS is designed to
facilitate the automated discovery, management and configuration of iSCSI
storage devices. By implementing iSNS support, Xtend SAN provides a
mechanism to simplify device discovery, reducing the time and effort
associated with the initial configuration of an iSCSI SAN.

* Login Redirect — Login redirect increases the availability and
reliability of the storage being accessed via Xtend SAN. Enabling login
redirect in Xtend SAN allows it to redirect users to their intended targets
in situations where the targets may not be available at the expected
address. Without redirect, the user would not be able to log in to the
intended target if it has moved.

“By providing this major upgrade to our Xtend SAN iSCSI Initiator for OS X,
ATTO continues to show its support for the iSCSI protocol, and further
cements ATTO’s position as the premier provider of iSCSI solutions for
Apple users,” states Tom Kolniak, director of products for ATTO Technology,
Inc. “ATTO has been developing iSCSI bridging products fully compatible
with the Mac OS for over five years, and with the introduction of Xtend SAN
v3.0, has developed a more capable, fully-featured iSCSI initiator
available today for Mac OS X.”

In addition to Xtend SAN, ATTO also carries an extensive line of iPBridges
that provides iSCSI connectivity to either SCSI or Fibre Channel storage
devices. When ATTO iPBridges are combined with Xtend SAN, SCSI and Fibre
Channel storage devices are transformed into iSCSI-enabled devices which
Mac OS X users can access via their Gigabit Ethernet port. This allows Mac
OS X users to fully realize the benefits of SANs in general, and iSCSI
