My experience with 9940B drives (in a PowderHorn) has been that ACSLS and Gresham are pretty reliable packages, but the 9940B drives themselves are pretty high-maintenance items. The drives need a fair amount of care and feeding (microcode updates, troubleshooting and log analysis, etc.) that have to be done by a StorageTek engineer. You can share an STK silo with multiple applications as long as you buy Gresham's EduTape. The good news: with TSM version 5.3 you don't need Gresham; native ACSLS sharing comes with 5.3. The bad news: you'll have to buy Gresham anyway if you use NBU. WARNING: Gresham is *very* expensive. Why would anyone want to replace 3592s with 9940Bs? <shudder> That's rather like replacing a decent lean-cut beef chop with top-of-the-line dogfood. -- Mark Stapleton ([EMAIL PROTECTED]) Berbee Information Networks Office 262.521.5627
