DAFS, despite its long existence and perceived popularity, has not yet been widely used as a standard, for large distributed systems. On the other hand SAN attached file systems seems to be creeping in as an alternative, boosted by the fact that it has been used successfully in commercial ventures. Do you see SAFS competing with DAFS as a future industry standard?
@shashank : I don't think it can be used over a WAN as DAFS is designed for high throughput and low latency networks(combining the advantages of SAN and NAS). Hence the number of clients will be limited. Hence WAN usability may not be possible.

ReplyDeleteWhat are caching issues in user-level file system clients. how they are addressed
ReplyDeletecan you compare the performance of kernel based DAFS vs low-overhead kernel based NFS?
