Sonnet Fusion RAID Expander extends PCIe bus outside computer

Sonnet Technologies has announced the Fusion RAID Expander, which can be used to connect up to seven Sonnet Fusion SATA RAID desktop or rack-mounted storage systems to a single computer for access to up to 56TB of protected storage.

The Fusion RAID Expander extends a computer's PCI Express (PCIe) bus outside the box and provides seven slots for installing PCIe cards. The Sonnet expansion system delivers plug-and-play installation and is transparent to the computer's operating system for zero-configuration use.

The primary advantage of connecting more than one storage system to a computer is the ability to scale the capacity and increase performance. For example, two 8TB Fusion D800RAID storage systems connected to the Fusion RAID Expander, with their drives configured as protected RAID 5 volumes and combined as one 16TB logical unit, sustain transfers of 645MB/s write and 670MB/s read.
