The PCIe 2.0 Workflow Speed Advantage The Accusys A12S2-PS utilizes new PCIe2.0 technology, which doubles the speed of PCIe data storage transmission providing highly desired improvements in speed as well as transfer efficiency over other interface systems. The high-speed advantage of the PCIe2.0 data storage transmission interface is its 500 MB/s bandwidth in each of four data transmission channels. This allows the A12S2-PS to reach 20Gb bandwidths. In addition, its unique “no signal protocol conversion” between the host system and the A12S2-PS brings efficient data transmission with surprising speed compared to other interfaces.
All protocol conversion from PCIe to other protocols, such as FC, SAS or eSATA, is performed using the HBA (Host Bridge Adapter). The adaptation process decreases the data transmission rate of native PCIe speed dramatically. In addition, the controller processor uses native PCIe transmission interface protocol to communicate with the host via the PCIe bus. It must be converted into a lower transmission rate to correspond with FC, SAS and eSATA. Facing protocol conversion lose, traditional external disk array systems cannot play at original speeds.
The Upscale PCIe 2.0- Comparisons
Every PCIe 2.0 path runs at 5Gb/s and the A12S2 RAID controller and QSFP cable contain 4 lanes of PCIe 2.0 paths providing a bandwidth of 20Gb bandwidth, resulting in upscale data storage transmission performance 2.5 times fasten than 8Gb FC !
A Slim and Elegant Disk Array System In a 2U12 bay form factor, the A12S2-PS only occupies a 2U space providing 20Gb Bandwidth with a max. storage capacity of 36TB. It combines performance and economics with an attractive new elegant, yet high-tech metallic casing.
Control Management Reliability The A12S2-PS transforms the disk array system into a convenience for all users, not only professionals. Its swappable modular disk array design, RAID controller, FAN and power supply module dramatically facilitate both maintenance and system reliability. Our innovative green storage, from an environmental protection perspective, is a model of energy efficiency and reduces storage system energy consumption while improving storage performance per watt. The A12S2-PS also runs cooler and enables significant cost savings for IT departments through its energy efficient green design.
Up and Running, At All Times
All ExaSAN storage solutions utilize the RAIDGuardX GUI system to manage and monitor the staus all parameters including power, fan, temperature, RAID controllers, easy trouble shooting features are also provided by Accusys: 1.) Every modularized component of the A12S2-PS system, such as power supply, fan and RAID controller has a corresponding front panel LED indicator. 2.) A warning beepen tone is emitted based on system status for quick servicing. Events requiring attention are entered into an eventlos and e-mail notification is seat.
Shared Storage Workflow Up-grading to a SAN is a must for even the heaviest editor workloads, and with an ExaSAN compact solution kit you have made the best SAN choice.
