Re: Veritas Quick I/0 and Oracle/ Asycnchronous I/O

Hmmm.... so it's a pci only interface, so I can't use it with my Enterprise Sun systems, and drivers for Tru64 don't yet exist, so unless you're running Windoze, AIX or Linux, you're out of luck. That's a real bummer.

Anyone use Imperial's solid state disks? I played with them at a clients a few months ago. I had a few problems with DMP but they were otherwise very impressive. Fiber interface, so you can put them on a fabric switch and share them between your hosts.
