Accurate transfer time calculation

[bernie321]

Hi

I need to transfer data off of a server to a desktop. The server is a novell server so rather than poping a disk in it and getting a the files on a novell file system, i need to transfer it across the network. I will probably just plug in a crossover cable between the machines at 100Mbps.

I have attempted to calculate the time but i come up with around 14 minutes for 10GB (which seems a little unrealistic). How much overhead should I be allowing for checksum etc and disk access and writing (server disk SCSI, desktop IDE).

Cheers B

It is difficult to say because the speed of your hard drive is also a factor. The average effective rate on switched networks seems to be around 15 megabytes per second on 100baseT. Since you are going straight through using crossover, I imagine your rate will be better.

Perhaps testing a 10Mb or 100Mb file can give you a better idea of what your transfer rate will be.

Thanks Jason,

I have done some testing on IDE disks (but faster machines) I am looking at about 40 mins.

So I will leave myself an hour on-site (its difficult finding time when the network is not in use).

Thanks again
