Q:

I am developing a system which deals with a large amount of data:

  • Typical file size 50 MB – 350 GB
  • Number of files in system 50-300 so total capacity up to 60T
  • The system must support 1-2 writers and 1-4 readers
  • The most important requirement and the most critical issue is a throughput rate – 20-150 MB/second per reader/writer

What are the storage configuration and technology more suitable for that system?

  • RAID + SAN
  • RAID + NAS
  • RAID + direct reader/writer connection

A:

Chuck Kelley’s Answer: Well, this doesn’t seem to be a data warehouse or business intelligence question, but here goes. Based on the information you gave and making a lot of assumptions, I think that RAID + direct read/writer connections may be the best way to go only because of the size of the data and the higher side of the throughput required. My second choice with be SAN, followed by NAS. SAN is optimized more for transaction processing while NAS is for availability/collaboration.
