A storage area network is being selected for NIDA servers. Which characteristic distinguishes a SAN from ordinary network attached storage?
Answers
AA SAN provides file level shares that users access directly over the network
BA SAN presents block level storage directly to servers, so the server sees a disk rather than a file share
CA SAN is always slower than NAS because it uses shared ethernet
DA SAN can only be accessed by one host at a time
