Designed to take
advantage of the high-speed PCI Express I/O architecture of Apple's Intel-based
MacPro workstations and Xserve servers, ExpressSAS RAID adapters deliver the
high performance required for digital media production and delivery, streaming
applications, I/O intensive server requirements and other data intensive OS
The ExpressSAS RAID adapters feature a low-profile form
factor that fit standard-length PCI Express slots, making them suitable for
compact designs. The ExpressSAS products also offer users selectable port
configuration options, enabling customers to select the optimal mix of internal
and external SAS connections.
The new RAID controllers leverage Atto's high-performance
RAID technology and Intel's new 800MHz PCIe Intel IOP348 I/O processors with
integrated XScale technology. Advanced fault-tolerant features include hot
swap, hot spares, online capacity expansion, battery back-up, and optimized
disk utilization for SAS drives, SATA II drives, or any combination of the two.
These adapters support standard RAID levels 0, 1, 5, 6, 10,
50 and 60, and feature Atto's DVRAID, making them capable of handling demanding
Mac-based digital media applications, such as 2K and 4K film; multiple layers
of complex, uncompressed realtime effects; and high definition video editing.
