One of the things I just purchased for my firm is a new Dell PowerVault 132T LTO2 tape library. LTO2 tapes are the next generation of linear tape cartridges similar to older DLT. They have a built in table of contents chip (similar to AIT tapes) so that drives can detect what is on the tape without having to read from the tape at all.
They hold 200gigabytes native or up to 400GB compressed and write at 36megabytes/sec native. So it's a tape that stores a ton of info and is about as fast as a modern IDE hard drive. The 132T holds 21 tapes for 4.2 terabytes of total storage.
Don't know how good it will be but I can't wait to find out. I've been waiting to get my hands on an LTO tape system since they were introduced about 2 years ago.
Anyhow, that's my example of a new (relatively - LTO2 has been out for about 8 months) technology available to IT Managers to help them run an enterprise. Let me know if you have any examples of new and fascinating products/technologies that are now available.
