Re: transferring data from one location to another

Bandwidth is independant of user-time.
 
I also ran the calc for a 2-cube box from NewYork to Sydney
 
1 8mm tape = 9.6sq inches (approx).
1 2cube box = 13824sq inches
 
1 box will hold 1440 tapes @ 8Gb each = 11.52Tb data
 
UPS quotes 8 day door-to-door delivery (NewYork - Sydney) for $231.08
 
8 days = 691,200 seconds.
 
11.52Tb / 691,200sec = 16.67Kb/sec
 
Option 1:
    Send 10 boxes and you get the equivalent of an ADSL bandwidth.
    Cost = $2310.80 USD
 
Option 2:
    Use dlt tapes @ 70Gb / tape = 69Kb/sec
    Send 3 boxes for ADSL bandwidth
    Cost = $693 USD
 
 
Bottom line for the original question:
 
    Cut a few tar tapes, put them in a UPS express envelope, ship the suckers.

        yeah, but your bitrate sucks (bandwidth over time)....sure, you can send 4 terabytes, but it takes two weeks to get there. :)

                ok, substitute "station wagon" for "cargo container" and put it on a plane or a ship.
                 
                Then do the math. The numbers you get boggle the mind (in terms of bandwidth)!

                        dude, if you can drive a chevy station wagon from the us to australia, patent the technique.

                                Old unix-sysadm maxim:
                                 
                                    Never underestimate the bandwidth of a 56 Chevy station wagon travelling down the highway at 60 mph loaded with 8mm tapes.

                                        how much bandwidth between the sites? is it in encrypted link? does the data need to be secure in transit?

                                                Guys,
                                                
                                                I need to transfer/restore approximately 75-100gig of data residing on a couple SP nodes here (US) to an AIX server in Australia. This is required in order to refresh a Sydney development environment w/ a copy from our production corporate Financials
environment. This will include application code (many small files) as well as 50+gig of database files. We have TSM server running @ both the locations. Could you guys please discuss options(TSM ,non TSM ) around this and give me your recommendation on the best method to handle this.
                                                
                                                Thanks,
