ATTO Technology Showcases Innovative Storage Infrastructure
Solutions at Macworld for OS X Environments

SAS/SATA, Storage Appliances, 4-Gb Fibre Channel, iSCSI, and Ultra320
Top Product List for High Bandwidth Applications

Macworld Expo, San Francisco, CA, January 9, 2007 – ATTO Technology, Inc., a global leader of storage connectivity and infrastructure solutions for data-intensive computing environments, is showcasing its FastStream™ Storage Controller appliance and its new SAS/SATA RAID adapters that enhance workflow productivity from SD through HD, all the way to 2K and 4K film for the broadcast and post production environments. Located in Macworld booth S1243, ATTO will demonstrate its FastStream Storage Controller running with Apple’s Xserve® RAID storage. This demonstration addresses the need to add RAID protection to critical data without suffering the performance impact associated with more traditional solutions. ATTO will also display its new SAS/SATA RAID adapter featuring DVRAID that provides parity protection in highbandwidth environments.

Designed as slim 1U 19” external rack that integrates into existing SCSI storage, FastStream adds data protection and storage networking. FastStream provides 480 MB/sec. performance with cutting edge 4-Gb Fibre Channel SAN connectivity and/or Ultra320 interfaces for easy connectivity to any SCSI or Fibre Channel storage. Designed to enable direct-attached storage to become part of a storage area network, FastStream allows unused storage to be reclaimed and made available to the servers that need it most. The FastStream Storage Controller is JBOD and RAID 0, 1, 5, 10 configurable. Add RAID to existing storage devices to guarantee high storage availability, prevent data loss and eliminate failures from individual storage systems. Existing RAID volumes can be expanded, mirrors added or RAID levels changed dynamically while keeping all data intact. The provisioning feature enables optimal use of storage assets and the ability to modify the storage infrastructure with minimal or no disruption to application services. Management is simple with the ATTO ExpressNAVTM integrated management console. An intuitive point-andclick interface allows for remote configuration, management and diagnostics.

The ATTO ExpressSAS RAID Adapter family provides SAS/SATA II connectivity and delivers blazing-fast performance with transfer rates of up to 3-Gb/sec. per port. It is the industry’s only low profile line of adapters offering user selectable port configuration options. Featuring advanced fault-tolerant features that include hot swap, hot spares, online capacity expansion, battery back-up, and optimized disk utilization for SAS/SATA or SATA II drives, or any combination, the ATTO ExpressSAS R348 and R380 adapters deliver an intelligent and robust low profile RAID solution. These adapters support standard RAID levels 0, 1, 5, 6, 10, 50 and 60 and features ATTO’s exclusive DVRAID, making them capable of handling the most demanding applications such as 2K and 4K film, multiple layers of complex, uncompressed real-time effects, and high definition video editing.

“This year’s Macworld will provide us the opportunity to demonstrate how ATTO solutions support high-bandwidth applications in multiple environments. We will also showcase how ATTO storage infrastructure solutions simplify and improve the digital media workflow for both standard and high definition videoproduction and broadcast environments,“ states Ed Tierney, director of marketing for ATTO Technology, Inc.
