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.

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.

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.

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.

Concatenated – This solution is not recommended due to lack of redundancy

and limited performance.
