  Superior 1200MB/s speeds to edit HD, 2K and 4K DPX
 

The ExaSAN A12S2-PS, the newest member of the ExaSAN family, offers high performance, availability and scalability. It features PCI Express 2.0 technology capable of reaching read speeds of up to 1200MB/s with only twelve drives and can easily perform on multiple HD, 2K and 4K DPX video formats, even dual stream stereoscopic 3D editing workflows. The A12S2-PS storage system brings high speed shared post-production workflows while reducing downtime.

 

     
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 !

 

 

  Meeting all Workflow Challenges
  Highly scalable, the A12S2-PS brings cost-performance savings to expandable storage systems for broadcast and post-production tasks such as color grading, film scanning, effects, finish, 4K & 5K red format editing, and much more.

  Functionality for Reliability
Video streaming applications have a strong requirement for very smooth, steady and sustained performance to prevent frame dropping. Overcoming these issues Accusys provides the EQ Mode and the DLP functions.
  Equalization Mode
By selecting the RAIDGuard X GUI, the “Performance Equalization mode” can be used to prevent frame drops, ensure smooth I/Os, and achieve stable performance with the smallest peaks in bandwidth fluctuation, meaning that users can regain as much as 20% in dropped storage.

 

 

 

 

  DLP (Disk Lag Proof)
RAIDGuard X also utilizes DLP technology. In the event of a single hard disk read speed performance degradation, delay or aging, other hard disks can resume stable I/O data transfer of corrected data in real-time based on RAID parity.

 

 

 

  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.

 

 

Highly Expandable PCIe SAN Ready
  In video editing, demand for capacity and speed are higher. The A12S2-PS supports the latest 3TB external hard drive, and it also has 6Gb SAS JBOD expansion option, permiting the RAID user to add up to three JBOD systems for up to 144TB(A12S2-SJ), Dual Port QSFP HBA allows User's wokstation to connect to two A12S2-PS and the combined speed can reach 40Gb, suitable for demanding Ultra-high speed application.
  Dual port QSFP HBA *A12S2-SJ JBOD
System Expansion
  Allows two storage systems connected to one host, able to carry 40 Gb bandwidth.   One RAID system supports up to three JBOD systems for storage capacity expansion.
