Amherst, NY (October 26, 2007)
– ATTO Technology, Inc., a global leader of storage connectivity and infrastructure solutions for data-intensive computing environments, announces driver support for its line of SCSI, Fibre Channel and SAS Host adapters for Apple OS X Leopard.  ATTO ExpressPCI SCSI adapters, Celerity Fibre Channel adapters, and ExpressSAS® adapters are the only PCI Express (PCIe) and PCI-X adapters available today that support Apple OS X Leopard.
“ATTO reinforces its commitment to the Apple market by being the first host adapter vendor to deliver support for the newest operating system, OS X Leopard. Mac users can now choose from a full spectrum of high-performance adapters for SCSI, Fibre Channel and SAS environments,” states Ed Tierney, director of marketing for ATTO.

ATTO's ExpressPCI UL5D is a dual-channel SCSI host adapter that combines four lane PCI Express technology and Ultra320 speeds for high-performance environments and applications such as high definition video, special effects rendering and non-linear editing.

Moving data at express speeds without bottlenecks is ensured with the ATTO Celerity Fibre Channel
single-, dual- or quad- channel host adapters.  The combination of PCI-Express and 4-Gigabit Fibre Channel technologies enables applications such as high-definition video editing, 2K digital production and transactional environments such as databases to take advantage of the 800 MB/sec. per channel throughput performance.  Featuring ATTO's exclusive Advanced Data Streaming (ADS™) Technology, large blocks of data move faster and more efficiently on the PCI bus than any other host adapter on the market.

The ATTO ExpressSAS® R348 and R380 low-profile RAID Adapters provide 3-Gigabit SAS/SATA II connectivity and brings a new level of flexibility for data transport. Featuring integrated RAID support with flexible port configuration and performance levels, enough to handle the most demanding applications such as 2K and 4K film, multiple layers of complex, uncompressed real-time effects, and high-definition video editing.

The ExpressSAS® H380 offers connectivity through two external x4 MiniSAS SFF8088 connectors, while the H308 model utilizes two internal x4 MiniSAS SFF8087 connectors supporting up to 256 devices when connected through SAS Expanders.  Each of the eight ports on the ExpressSAS® adapter is capable of delivering up to 300 MB/sec.

"ATTO's complete line of SCSI, Fibre Channel and SAS adapters ensures the throughput required for handling massive media files without bottlenecks.  ATTO Technology will continue to set the standard for high-performance adapters and will continue to deliver industry-leading solutions that meet our customers' performance expectations and aggressive time-to-market requirements," said Ed Tierney, director of marketing for ATTO.

ATTO also offers several software based productivity and performance enhancing solutions for the Apple OS X market.  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).  By installing the Xtend SAN iSCSI initiator on an OS X workstation, users can leverage key SAN applications such as collaborative digital video/audio workflows, laptop connectivity to SANs, and remote backups.  ExpressStripe is a disk storage application that provides RAID Level 0 functionality and benchmarking software for the Mac OS X operating system.  This software allows users to enhance the performance of attached, SAS, SATA, Fibre Channel, SCSI and FireWire storage.
