ExaSAN RAID Storage Optimizes 4K Video Editing Performance
Accusys announces the latest PCIe storage-A16S3-PS. This whole new storage is designed for 4K video editing. With it, media professionals will never feel annoyed with lags and dropped frames.
New Taipei City, Taiwan, November 04, 2014 --(PR.com)-- The new ExaSAN A16S3-PS is 16-Bay rack mount RAID storage designed for 4K video editing, based on PCIe 3.0 emphasising speed and capacity. It has SAS/SATA/SSD HDD support, and up to 2500MB/s read and 2100 MB/s write speeds in order to handle 4K video storage performance and volume size.
One workstation attached to one A16S3-PS can reach approximately 2500 MB/s with a maximum capacity of 64TB based on 4TB capacity.
The 16-bay unit holds three linear or spanned volumes and is compatible with the ExaSan C1M, a PCIe to Thunderbolt 2 converter, and 3.5in and 2.5in SATA/SAS/SSD enterprise hard disks making it suitable for PCIe DAS and SAN. It has PCIe 3.0 32 Gb bandwidth and supports RAID Level 0, 1, 5, 6 and 10. Accusys has developed a PCI Express SAN architecture for their ExaSAN products to include components required for the video and audio production DAS and SAN storage environment.
The current ExaSAN storage, switch and host bus adapter products, employing PCIe 3.0 protocol, achieve 8 Gb/sec per lane transfer rate. With 4 lane QSFP, or quad small form-factor, connectors and copper or fibre cables, ExaSAN can transfer up to 32 Gb/sec using single port QSFP HBAs.
In video post-production editing scenarios, where storage speed, video stability and smooth-running workflows are required, high speed access to video files must be maintained and the flow of video frames should be uninterrupted without dropping frames. Overcoming frame drop in high bandwidth video applications is a challenge because using a performance range with the lowest peaks in a fluctuated bandwidth may cause significant loss of average disk bandwidth. Accusys has developed several performance optimization techniques for video editing storage.
Equalization Mode, for example, is an access command that adapts the RAID controller memory caching management behavior and makes continuous I/Os smoother and reduces large fluctuations during data transmission. The goal is re-gaining the loss in bandwidth.
When one hard disk in the RAID 5 or 6 set is slow in responding, Disk Lag Proof will perform a fast data regeneration using the correct data and parity from the remaining hard disks in the RAID set. During regeneration the host system will continue receiving correct data and normal response time from the RAID set, and the user can continue to edit video without frame drops.
RAID slicing changes the way data is stored on an HDD or RAID system by subdividing a RAID array into segments or slices, which act as hardware partitions of all drives in the array. Each slice appears as a separate volume on the host computer. RAID slicing suits A/V applications where sustained transfer rates are important but tend to vary depending whether they are 2K, 4K video or audio files.
