There are so many technology companies that have jumped on the SATA bandwagon as the cheap, mass, high-performance, high-availability storage solutions. Well, two out of four pretty much sucks when it's *your* money (and various anatomical parts) out there on the line. Yes, it is cheap, and it does mass storage pretty well. But it was *never* meant to be a high-performance, 24x7 solution. SATA was originally designed to be touched on occasionally, as you would when you place seldom-touched files in storage that must be easily available (unlike tape). Accessing data frequently when contained in SATA storage is (at best) a questionable practice; I would *never* use a SATA pool for a primary TSM storage pool. -- Mark Stapleton ([EMAIL PROTECTED]) USBank MR Backup and Recovery Management ------------------------------------------------------------------------------ Electronic Privacy Notice.
