ATTO introduces the ExpressSAS R348 Low­Profile RAID Adapter. Providing 3-Gb SAS/SATA II
connectivity with integrated RAID support and
flexible port configurations, the ATTO SAS RAID
adapter is ideal for both IT and digital video
environments that require a high level of data
protection and performance.

The ATTO ExpressSAS host adapter product
family provides enhanced reliability and
performance thanks to more than 15 years of
experience with SCSI hardware and storage
connectivity solutions. Using PCI Express bus tech­nology and the flexibility of either a 4 external and 4
internal or an 8 internal user selectable port con­figuration, the ATTO ExpressSAS R348 adapter
delivers blazing-fast performance with transfer
rates of up to 3-Gb per second per port. With two
x4 Mini SAS connectors, configured internally or
combined internal and external, the R348 provides
connectivity of up to 128 SAS/SATA targets. The
R348 also features 256MB of ECC-protected
DDR2 DRAM to allow support for multiple RAID
groups.

The ATTO ExpressSAS RAID adapters are
engineered for the most stringent IT server and
digital media workgroup environments. To satisfy
the data protection requirements of these
environments, ATTO leverages it’s time tested
ATTO RAID Stack (ARS™) technology based on a
proven RAID core that is compatible with multiple
operating systems, applications, and drives.

The easy-to-use GUI utility enables RAID
management, monitoring, and configuration. ATTO
also incorporates it’s field proven Advanced Data
Streaming (ADS™) technology to meet the most
demanding performance requirements of data
intensive applications. In addition, ATTO provides
industry standard PCIe to SAS control using Serial
SCSI Protocol (SSP), Serial ATA Tunneling
Protocol (STP), and Serial Management Protocol
(SMP).
