ATTO’s iSCSI Software Initiator for Mac OS X provides Added Security and
Enterprise-Class Features for Large-Install Environments

New Xtend SAN Software provides CLI and Digest Support for OS X iSCSI targets

Amherst, NY (January 5, 2009) — ATTO Technology, Inc., a global leader of
storage connectivity and infrastructure solutions for data-intensive
computing environments, announced today that its industry-leading iSCSI
Software Initiator for Mac OS X, Xtend SAN has been updated with
enterprise-class features to provide better security and automation for
medium to large installations. Xtend SAN now supports HeaderDigest and
DataDigest with error level 1 processing; which is used to guarantee the
integrity of iSCSI header data. The new Xtend SAN Command Line Interface
(CLI) enables almost complete automation of iSCSI target management. This
greatly benefits larger installs where the need to execute commands in
script or batch modes from workstations with minimal to no user interaction
is required.

This version of Xtend SAN provides transparency for OEM customers in
environments where greater security and automation are required. Enterprise
customers who require the security and data integrity provided with Header
and Data Digests can now find this as part of the latest version of the
Xtend SAN initiator.

“The traditional Xtend SAN Graphical User Interface is still available,”
stated James U’Ren, Product Manager for Xtend SAN, “ATTO customers expect
our products to be easy to use out of the box, so that functionality did
not change. The option for CLI is presented upon installation of Xtend SAN;
this will address customer requests to provide a more streamlined process
to access multiple iSCSI targets.”

This release builds on the many great features supported by Xtend SAN which
help users of every level access their iSCSI storage from a Mac workstation
or laptop computer including: Challenge-Handshake Authentication (CHAP),
Internet Storage Name Service (iSNS), Login Redirect and iSCSI error
handling and recovery. Xtend SAN is the first and most widely-distributed
application that allows Mac users to attach existing storage to an IP-based
network. With Xtend SAN, users can take existing direct-attached storage
devices and make them available to multiple servers, increasing
accessibility and simplifying storage management, while leveraging existing
IT expertise.
