Disk array system for streaming environment demand
ExaRAID HD is an innovative, highly efficient and cost-effective solution for the entire broadcast and post-production market. External PCI Express technology enables disk arrays to be used in conjunction with editing workstations with a high-bandwidth transfer performance of 20Gbps.The ExaRAID HD family of products includes 2U 12-bays, 3U 16-bays and 4U 24-bays. The 3U and 4U RAID systems are configured with single-controller and dual independent controller systems. ExaRAID can be used on any of the latest hard disk specifications. Coupled with the “zero protocol conversion loss” feature of PCIe, the ExaRAID HD is also capable of maintaining high speeds and reducing transmission delay in continuous read/write, thereby maximizing the utilization rate of every single hard disk.
Amazing read performance of 1400MB/s
ExaRAID HD 3U 16-Bay dual independent controllers RAID system is capable of providing an amazing read performance of 1400MB/s, mainly through a PCIex8 interface that has a transfer bandwidth of 20Gb. As a result of External PCI Express technology, the transfer of data between ExaRAID HD and workstations is similar to that of the workstation’s internal high-speed transmission processes Compared with the higher-priced 8G, 4G FC and 3G SAS disk array systems, not only does the ExaRAID HD solution have the advantage of twice the bandwidth. Coupled with the “zero protocol conversion loss” feature of PCIe, the ExaRAID HD is also capable of maintaining high speeds and reducing transmission delay in continuous read/write, thereby maximizing the utilization rate of every single hard disk. ExaRAID HD also provides an upgradable single-controller system, which boasts a bandwidth of 10Gb. The system transfer rate of the 3U 16-Bay is able to reach 700MB/s and above, which is equivalent to the maximum performance of a dual 4G FC RAID system.
Why PCIe?
PCIe high-tech specification, which provides 250MB/s bandwidth in each channel , the ExaRAID HD has four and eight data transmission channels that is the reason why ExaRAID HD can reach 10Gb/s and 20Gb/s bandwidth. Comparing with Firewire technology’s 250~300MB/s throughput rate,ExaRAID is far faster. The ExaRAID HD’ high performance not only stands for maximizing the utilization of every HDD but also represents the quality、standard and efficiency at film editing process for media workgroup.

RAIDGuard X
RAIDGuard X—offers an intuitive way to configure the RAID in only four simple steps. It boasts remote management functionality. Any event can be sent to users through simple operations such as email or pop-up windows. In addition, protection and monitoring functions are available so that users can easily configure, monitor and manage the RAID and other system status information.
In addition, the ExaRAID HD can be used to configure and monitor the status of the RAID through the LCD panel. The LED lights on hot-pluggable hardware chassis will indicate the usage real-time status of the hard disks. All of these designs work together to optimize the safety of digital data.
The ExaSAN can be fully integrated with Xsan and Final Cut Pro system, which can implement a shared volume and shared editing SAN environment. In a addition, ExaSAN PCIe HBA is also compatible with the non-MAC workstations such as Windows, Linux and Unix platforms. With SAN management software from MetaSAN and StorNext, user can use workstations with different platforms to access ExaRAID HD media content simultaneously, realizing a viable cross-platform SAN framwork. ExaSAN affords users the most flexible workflows and it meets the requirements of multiple applications.
