Hello, from what I know about currently available tape technologies I guess that AIT-2 technology might be best for TSM, because its performance strongly relies on short search times and on short tape load/unload cycles. Tis technology seems to be reliable and durable enough as well. Can anybody either confirm or disprove that for me? best regards Juraj Salak Austria -----Ursprüngliche Nachricht----- Von: Richard Sims [mailto:[EMAIL PROTECTED]] Gesendet am: Freitag, 20.

Debbie - I think many of us have been wondering what the reality of 3583 LTO Ultrium tape drives would be, and your posting may incite more exploration. As I understand the LTO initiative, Ultrium was intended to sacrifice performance for capacity, while the Accelis flavor was to favor performance but offer limited capacity. My reading says that Accelis development was abandoned in favor of the higher capacity that the marketplace would want with Ultrium. But your question makes me wonder how much performance may have been compromised. Perform the tar test that Paul recommended and let us know what you are able to determine. thanks, Richard Sims, BU
