High performance RAID storage – scalable, reliable and affordable.
Accusys provide fault tolerant data storage solutions that connect to a host system via a connection which is over twice as fast as 8Gb Fibre Channel, that can span 100m distances, and that can be used to form a complete Storage Area Network (SAN) solution without incurring the high costs associated with a fibre channel infrastructure.
The Accusys 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 in excess 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 makes high speed shared post-production workflows more affordable than current fibre channel solutions. The system is compatible with Windows, Mac and Linux.
The A12S2-PS utilises an external PCIe connection to provide 20Gb/sec bandwidth without the protocol conversion which reduces the efficiency of other connection formats such as Fibre Channel or SAS. Using copper or optical cables this connection can be made from 2m to 100m without degrading performance. It can even be routed through an Accusys PCIe switch to share storage between systems or to create a SAN environment.

The A12S2-PS can be easily configured and maintained by anyone, not just professionals. The modular design provides swappable drives (SATA or SAS), RAID controller, FAN and power supply modules dramatically reducing maintenance time and increasing system reliability. From an environmental protection perspective, the A12S2-PS is a model of energy efficiency reducing storage system energy consumption while improving on traditional storage per watt performance.
The A12S2-PS supports the 3TB hard drives, comes with 6Gb SAS JBOD expansion capabilities allowing the user to add up to three JBOD sub-systems (A12S2-SJ) for up to 144TB’s of storage. A Dual Port QSFP HBA allows a wokstation to connect to two A12S2-PS arrays so the combined speed can reach 40Gb/sec, providing enough bandwidth for the most demanding Ultra-high speed application.
Single System Configuration
- Workstation directly attached to A12S2-PS via Copper (2m/5m) or Optical (10m>100m) cable
- 20Gb bandwidth, up to approximately 1200 MB/s performance when fully populated with 12 drives
- Max. certified capacity 33TB in RAID 5 (12 x 3TB drives) – *4TB drive certification coming soon.
- High performance to cost ratio for ideally suited for 4K workflows
In its simplest form the Accusys A12S2-PS provides fast and reliable direct attached storage for one workstation. With its high bandwidth and reliability it is ideally suited for high resolution or multi-stream editing systems.
Ultimate Performance System Configuration
- Workstation directly attached to two A12S2-PS units via one QSFP dual port HBA
- 40Gb bandwidth, up to approximately 2400MB/s performance when fully populated with 24 drives.
- Max. certified capacity 66TB in RAID 5 (24 x 3TB drives) – *4TB drive certification coming soon.
- Scalable capacity via OS stripping of the two A12S2-PS
- Volume backup via OS mirroring of the two A12S2-PS
For maximum bandwidth and performance harness the speed of two A12S2-PS on one system. Using the PCI-e x8 dual port HBA you can attach two arrays for double the performance. Editors looking for dual stream 4k workflows need look no further than this setup.
Maximum Capacity System Configuration
- Workstation directly attached to two A12S2-PS units via one QSFP dual port HBA
- Each A12S2-PS connected to 3 x A12S2- SJ 6Gb SAS JBOD systems.
- 40Gb bandwidth, up to approximately 2800MB/s with the best load balance
- Supports Max. 96 drives, total capacity up to 264TB in RAID 5.
- Scalable capacity by OS stripping two A12S2 and six JBOD systems
With the same beautiful housing and hot-swappable hardware design as the A12S2-PS RAID system, the A12S2-SJ JBOD systems are able to utilize the A12S2 RAID engine and 6Gb SAS transmission speed. The A12S2-PS can support up to three JBOD systems connectivity with a dual QSFP port HBA in the host configuration. As a direct attached storage solution you can connect up to eight storage systems for access to a total of 96 high-capacity hard drives which could store approximately 60 hours of non-compressed 4K DPX film.
