Things are bring mixed up. It would probably be gige port via wan optimizer, found a 1 U model that houses SIX 2.5" bays so I'm leaning on R1 for OS and then R10 for the data.
Another question....and I'm not sure what would be the crux.
The data will be uploaded from site a via ethernet to site b. Site b will house the *storage server*
The data on Site A being uploaded....
firewire drive connected to notebook connected via gige
notebook with *larger hard drive* connected via gige
Just to agree with the other person, on 100mbit your harddrives will keep up. No need to spend money on 15K drives. And you may as well do RAID1 for data safety. Look into TCP/IP tuning to get the most out of the 100mbit.
RAID0 or RAID1? With RAID1 you'll have the write speed of one drive, so chances are not even a pair of 15K drives would be able to keep up (maybe a pair of Seagate 15K.6s would, and that would still require a very sequential workload). With RAID0, two current generation 10K drives would stand a decent chance, obviously varies on the model and the workload. Although having said that, if going with RAID0, a pair of current generation 334GB per platter drives (WD 640GB, Samsung 640GB, etc etc) would also be able to keep up fairly decent *assuming* a fairly sequential workload.
