Sanders: I don't think it's a fair assertion. First of all, tape -- while it is largely used in the archive market -- isn't solely used in the archive markets. Secondly, the archive market is a pretty damn big market. It's four times the amount of capacity than the entire worldwide external disk market we shipped.

That's traditional. Tape has always outsold external disk. But analysts say that's shifting.

Sanders: The market is not shifting. Archive is really at the infancy of its explosion. There's legislation out there.... Europe is evaluating whether every single telephone call needs to be captured. You going to put that on disk? No way. The trick with tape is just maintain technology leadership. Keep the 10:1-plus separation between low-cost SATA disk and tape and that market will be healthy for a long time.

You spoke a lot about virtualization in your speech here. Can you elaborate?

Sanders: Network-based virtualization is very real. Disk-based virtualization is also real. There's about 2:1 petabytes managed under network versus disk. Switch-based virtualization is chartware, for now. I don't think you can find any reference customers for that. You can find hundreds and hundreds of reference customers on network virtualization.
