If I understand you right you need to pull 500 GB/hour.
That should be around 140 MB/s and you would need a bandwith of at least 2
Gbit/s network for that.
I don't know LTO drives, but I know that the STK 9840 and 9940 can take
that kind of data without any problem day after day.
I have seen people use STK 9840 and 9940 and getting 35 MB/s to the tape
but that is a max. and depends mostly on your data.
If I had to do it in our shop (and we only have 750 GB disk) I would use
some 8 to 10 STK 9940 drives pulling the data directly from the server over
the SAN to the tape drives.
This should work fine with Sun, but I don't know anything about SGI
Is all the data on one server and is it something you need to do daily?
