We now have to use a storage (disk) simulator which can accept trace - file from ns-2 and give appropriate output, indicating how disk(s) has been used. Please, direct us as to how DiskSim can be used for this. Also, please give alternatives of DiskSim which we can use. Thanks everybody...

In the meanwhile, there is a toolkit for simulating storage networks, called SANsim. At least, I know a paper introduces it. I think you can find it from Internet. good luck.

It's a simple, line based ASCII format, which looks simple and quite understandable. Have a look at the different valid/*.trace files.

I found that there were two functions which were used for this, device_get_servtime and device_get_seektime. While the latter is self-explanatory that it finds seek delay, I'm not able to understand how does device_get_servtime find the rotational delay? Also there's another function device_get_acctime which I think has not been completely written in the version i have. Would really appreciate if you could tell me how device_get_servtime finds rotational delay or is it a sum of seeks and rotational latency? Thanks. Mayank.

I am attempting to add RAID6 to disksim, and I have tried to simply copy the parity_rotated code into a subroutine which I named after RAID6. When I try to run even this, I get an error which tells me "unknown maptype at logorg_RDP - 4" even though I never changed the mapping type. Has anyone else tried to do something similar to this that could lend me some advice about what the error might be?
