The one MAJOR PITA issue I had w/them is w/LSI 320-1 MegaRAID cards. A mirror using "slot 1" degrades under moderate load and cannot be recovered. The problem goes away w/320-2x. Tyan and LSI are investigating. Tyan reports "unable to reproduce/no problem found". Right.... LSI support, by contrast, rocks and they are investigating further. > And just because your data center is 300 miles away doens't mean you > can't manage it.

Doesn't the Sun use a Tyan board? -- Best regards, Ken Gunderson Q: Because it reverses the logical flow of conversation. A: Why is putting a reply at the top of the message frowned upon?
