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.
| The best scalability framework Design The ExaRAID HD offers not only the best scalability framework, but also meets the streamlined workflow requirements of a variety of digital editing work and editor can get ready for the next uncompressed HD editing workflow. Combined with Accusys’ unique ExaSAN Gen1 Switch, up to seven ExaRAID HDs can be connected to a workstation. If equipped with a hard drive of 1TB capacity, the high capacity of 168TB can meet the requirements of any ingest, editing, playout and archive application. More choice for capacity  If you want more requirement for capacity, ExaRAID is designed for more choices on capacity.
ExaSAN is a complete External PCI Express SAN solution that consists of all SAN components required for SAN deployment, such as the disk array system-ExaRAID HD, ExaSAN Gen 1 Switch, ExaSAN Gen2 Switch, Eternal PCIe optical cable and PCIe HBA. In addition to comprehensive quality assurance and a single contact window for customer support, the advantages of a single vendor also include the overall ExaSAN framework efficiency and implementation cost, which compares favorably with FC solutions. |
The function for performance
The ExaRAID HD is designed specifically for disk array systems that are used for real-time streaming environment. In addition to having high-bandwidth and high-performance advantages, Accusys has also included a number of application designs for sequential I/Os, such as:
Dual independent controllers
“Disk lag proof technology” can also be activated on RAIDGuard X. In the event of performance degradation or delay of a single disk due to aging, it allows the overall I/Os to resume its transfer response time and to provide stable performance based on the RAID parity.
Performance Equalization mode
This feature can be selected and activated on the ExaRAID HD GUI-RAIDGuard X. The “Performance Equalization mode” will allow the continuous I/Os to operate more smoothly and substantially reduce large fluctuations in efficiency during data transfer. In video editing applications, frame dropping can be prevented.
Disk lag proof technology
“Disk lag proof technology” can also be activated on RAIDGuard X. In the event of performance degradation or delay of a single disk due to aging, it allows the overall I/Os to resume its transfer response time and to provide stable performance based on the RAID parity.
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.
