4-Port External 4-Port Internal 12Gb/s SAS/SATA to PCIe 3.0 Host Bus Adapter

The ExpressSAS H1244 12 Gb/s SAS/SATA to PCIe 3.0 Host Bus Adapter from ATTO Technology provides high performance direct attach connectivity for server storage, JBOD and RAID arrays. With a wide variety of port configurations and built-in RAID 0, 1, 1e, and 10, these adapters offer flexibility for every range of application. The speed of the 12 Gb/s SAS interface, coupled with a PCIe 3.0 x8 host interface, delivers a dense and efficient connection to all types of storage, from rack-mounted servers and workstations in data center, data warehousing, VOD, and other high-availability, high-performance applications.

Industry Proven Technology
The host adapter provides data protection to direct attached SAS and SATA storage. With a wide variety of port configurations and built-in RAID 0/1/1e/10, this adapter offers flexibility for every range of application.

Flexible Connectivity Solutions
The adapter is available with eight ports to support an efficient connection to storage from rack-mounted servers and workstations in datacenter, data warehousing, VOD, and other high-availability, high-performance applications.

Performance
The adapter combines 12 Gb/s SAS speeds and PCIe 3.0 x8 with hardware and software elements to manage latency in real-time environments. Advanced Data Streaming (ADS) Technology maximizes CPU processes to deliver smooth and reliable data transfers, and consistent performance close attention to detail in board design and signal integrity to help minimize transmission errors and data corruption.

Advanced Management Tools
ATTO's easy-to-use ConfigTool features an intuitive GUI that simplifies the installation, management and monitoring of the host bus adapter. With advanced troubleshooting and performance tuning capabilities, the adapter provides you with sophisticated diagnostics and the flexibility to control settings for specific applications. The ATTO Technology offers a broad array of management and diagnostic capabilities. This adapter is able to help isolate cable and connector failures (and intermittent problems) through independent control of each port, as well as discovery and cable management of data passed through the mini-SAS HD connectors.

Advanced Data Streaming (ADS)
Latency Management technology that controls the acceleration of data transfers to move large amounts of data efficiently.
