Do you want a programming project, or a figure-out-how-to-do-it project? One thing that pops up once in a while is the need for a real-time distributed file server. I.E. two or more fileservers serving the same files from physically separate locations, while keeping the files synchronized in real time. One scenario is a business that has multiple offices and would like to reduce inter-office network traffic by having a synchronized file server at each local office, so read access is to the local file server, and only the (relatively rare) changes need to propagate across the network. Another quite common scenario is a laptop that you want to keep synchronized with your home fileserver regardless of where it happens to be on the Internet. There are assorted partial solutions to this problem, but I don't know of any that are entirely satisfactory for the general case (I admit, I'm not up on the state of the art in this area). For instance, running gmirror with one provider accessed via ggated is good for some situations, but doesn't encrypt the network traffic, and really just gives you one fileserver with real-time off-site backup. CMU's Coda filesystem purports to be a solution to this problem, but has pretty weak documentation (unless that has changed recently) and unknown reliability (setting up Coda on a pair of FreeBSD systems, documenting how to do it, getting some measurement of reliability, and reporting on the results would be a useful project, but if you are looking for a programming project I doubt it qualifies). Lots of people have written papers on related ideas. One collection of links is at http://www.cypherspace.org/links.html . You might get some ideas there. - Bob On 5/15/08, Onkar <onkar.n.m@gmail.com> wrote: > Can anyone please suggest me a good storage(File system ,SCSI/iSCSI stack, > TCP/IP ) project .
