Most drives have only a 1MB cache. I have a friend at Winchester Systems who's trying to sell me a SCSI-3 RAID box, and I think they'd be willing to let us borrow one for a test in return for favorable mention http://www.winsys.com. He says they work with fast differential 2944's as host cards. Is the DPT faster with the direct bus connection? No SCSI at all? Does anybody have experience with these new Compact PCI chassis that have 8 PCI slots? An obvious bottleneck for anything we can do is going to be the chassis limitation on most of 4 PCI. I believe the Compaq Proliant is EISA. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
