Key Features • Storage expansion system; connect to existing Fusion DX800RAID storage systems • Easy, Economic Expandability—Internal SAS expander enables you to connect up to 16 DX800RAID enclosures to a single Sonnet RAID controller card • Expansion storage system includes enclosure, eight 1TB Enterprise/RAID drive modules(1), and power cable Easy Storage Expandability When you need access to more assets than your Fusion DX800RAID can hold, Sonnet offers an economical upgrade path that is simple to deploy—Fusion DX800RAID Expansion storage systems. Fusion DX800RAID storage systems feature a internal SAS (Serial Attached SCSI) expander that enables you to connect additional DX800RAID Expansion systems in a daisy chain, no additional RAID controller card needed. This simplifies installation and significantly reduces your cost to expand capacity. As a matter of fact, incorporating more storage capacity is nearly as simple as placing additional Fusion DX800RAID Expansion systems on your desk and connecting a few cables. OS Compatibility • Mac OS X and OS X Server Versions 10.4.8+ (including Snow Leopard®) • Windows® 7, Vista®, Server 2008, Server 2003, and XP Pro • Linux (RedHat ES 3, 4; Suse RedHat ES 3, 4; Suse Linux 9, 9.1, 9.2, 9.3, 10, 10.1 and the following architectures: i386; x86_64 (AMD64, Intel EM64T) Hardware Compatibility • Mac, Windows, or Linux computer with Sonnet PCIe RAID controller and ATTO Configuration Tool software installed • Fusion DX800RAID storage system Technical Notes (1) Although most hard drive manufacturers define 1 gigabyte as 1,000,000,000 byte, the computer operating systems usually calculate a gigabyte by dividing the bytes (whether it is disk capacity, file size, or system RAM) by 1,073,741,824 (). This distinction may be a cause of confusion, as a hard disk with a manufacturer rating of 500GB may have its capacity reported by the operating system as 454.7GB.

NOTE: This model requires a Fusion DX800RAID storage system (part number FUS-DX8SR-xTB) to operate.
