I am interested in accessing large datasets (10's of GB) from a centralized storage facility to clients on remote workstations - cross country (5000Km), perhaps even overseas. Due to the latency introduced by the geographical distance, not all applications will perform satisfactorily accessing remote files. In such cases the entire or interesting parts the file would have to be (say) FTPed to the remote workstation and accessed locally. However, for applications remotely accessing chunks of data sequentially or nearly so, AFS may perform satisfactorily (using double buffering, etc). The local caching of AFS would even allow for a considerable amount of random accessing and still be more attractive than FTPing the entire file over and doing local access (esp. if the data access is random over the entire 10's of GB file). Are there any white-papers, or any other documents that would give an indication of LAN vs WAN performance of AFS - any application or data access profile would do since I have nothing at this time (my search has just begun)? Ditto for databases running over AFS (LAN vs WAN performance). Thanks for any help. Please email if you have any comments or questions. Dave Wiltzius Lawrence Livermore Nat'l Lab [EMAIL PROTECTED]
