Gus, <<Will SUNW/Compaq/HDS/Dell/NTAP ever sell branded directors?>> <<I think EMC will eventually force these vendors to OEM director switches because the type of software that seems to be developing for SANs will require seamless integration of the disk arrays, the HBAs and the switches. With its redundant control processors, the director, or networked directors in a SAN, is the ideal platform for developing a powerful data management scheme.>> I disagree with your reply to J. The driving force for using director class switches depends on the needs and desire of every particular installation. Unified network management software does not dictate more use of director switches. A unified network management software depends on switches built with standard 'MIPs'. The software platform can then manage the entire SAN(s) regardless if there is a mixture of director(64-128 ports) and 8/16 port switches in your SAN. My answer to J's question is yes but with different reasons. Let's save it for another day. KJ

This slide seems to have it all.... Today DAFS and NFS are targeted at different environments DAFS is NFS for VI and InfiniBand in-room networks Experiments showed NFS over sockets/VI to perform very poorly compared with DAFS NFSv4-based with memory-to-memory transport mapping and “local file-sharing” semantics User-space DAFS (performance) and VFS/IFS DAFS (transparency) implementations At the application level we would like DAFS and NFS to become semantically identical So if QLGC is to be big in Iband they need to know DAFS?
