Video bit rate: SD is Uncompressed 8 bit 25FPS (720 x 576)= 21MB/s / HD is Uncompressed 8bit 422 25FPS (1920 x 1080P)= 104MB/s. Note: All configurations
except for the maximum HD config use: 7200 RPM SATA Drives / 1X, 2X, 4X 6 Drive RAID 5 Arrays / 64K Chunk size / WBC set to Max / RAC set to Auto / 1 LD per
Array / Sequential Write Optimization set to High / Overload Management set to Disabled / Controller LUN Disabled / Atto HBA's and Atto Multipath Driver used /
Disable cache Writethrough operation when write cache is full / Disable Synchronize Cache Writes to Disk / The XSAN Metadata drive is on separate storage.

Based on performance
characterization done July
2008. Based on 4x RAID5
(5+1/)/(4+2), 24 drives,
QD=32, Chunk Size
256K, R2.4 (3.05.0020).
IOPS higher with more
drives, IOPS with WBC
Max. TQM is disabled.
