The ATTO Technology ExpressSAS low-profile host adapters provide 3-Gb SAS/SATA II connectivity for
both IT and digital video environments. The adapters are compatible with multiple operating systems,
applications and drives.
The ATTO ExpressSAS R380 host adapter and the
ExpressSAS R348 host adapter provide enhanced
reliability and performance thanks to more than 15
years of ATTO experience with SCSI hardware and
storage connectivity solutions. Using the latest in PCI
Express bus technology, the ATTO ExpressSAS host
adapters deliver blazing-fast performance with
transfer rates of up to 3-Gb per second per port.
An easy-to-use utility, ATTO Configuration Tool,
configures, manages and monitors the ExpressSAS
adapters.
ATTO also incorporates its field-proven Advanced
Data Streaming (ADS™) technology to meet the most
demanding performance requirements of intensive
applications. ATTO provides industry standard PCIe
to SAS control using Serial SCSI Protocol (SSP),
Serial ATA Tunneling Protocol (STP) and Serial
Management Protocol (SMP).
The ATTO ExpressSAS R348 is a low-profile SAS
host adapter configurable as four external and four
internal ports or as eight internal ports.
The ATTO ExpressSAS R380 is a low-profile SAS
host adapter with eight external ports.
