A REFERENCE GUIDE FOR OPTIMIZING DELL™ SCSI SOLUTIONS VER A02 that can afford some downtime and rely on backups to restore data, this could be a solution. Streaming Media Servers Streaming media servers are systems that provide web casting, video conferencing, internet entertainment like TV or radio, and multimedia content oriented services. These are systems that generally require a balance between storage capacity, availability, redundancy and performance. Like web servers, they may also be part of a group of systems that work together to provide content. • Table 2-15 Database General IO profile I/O Profile I/O Profile (Read/Write) (Sequential/Random) Bandwidth 98/2 Sequential Heavy IO Size >64K Latency Sensitivity High Growth Rate High Criticality Varies • Table 2-16: Database sever RAID Guidelines Application Streaming Media Concatenated 0 Recommended RAID Level 1 10 Not Recommended 5 50 Possible Recommended: • RAID 5 - Recommended for streaming media servers that require maximum storage capacity and only base data protection and performance. This would be recommended RAID configuration for stand alone streaming media servers. • RAID 50 - Recommended for those solutions that require a balance between storage capacity and performance. This solution would provide greater availability and redundancy but less storage capacity. • RAID 0 - While this solution is not redundant, this may be useful for streaming media servers that require better performance and are members of a cluster of servers where availability and redundancy is handled at a higher level. Possible: • RAID 1, RAID 10 - Possible solutions in situations which do not require high storage capacity. In general servers utilized for streaming media require large amounts of storage capacity for content especially uncompressed video. Not Recommended: • Concatenated - This solution is not recommended due to lack of redundancy and limited performance. Note: While these configurations are not recommended, they can be configured and utilized. PAGE 12 11/17/2005
