ATTO H1280 GT HBA | Ultrafast x8 PCI Express v4.0 SAS Interface


Through our partnership with ATTO we are pleased to be able to offer the ExpressSAS 12Gb H1280 GT host bus adapter (HBA). ATTO’s ExpressSAS series is one of only two currently available on the market that utilize the x8 PCI Express 4.0 host interface, offering the fastest available direct connection to SAS (12 Gb/s) and SATA (6 Gb/s) storage devices. It has eight external ports—which can be configured for dual-port redundancy—and can support as many as 2,048 end devices. Built-in latency-reducing technology ensures a consistent stream of data to the storage device, which speeds up write times and reduces wear on the tape because it will not need to make multiple passes due to data flow interruptions.
