The issue I've typically seen with 3Ware PATA setups I haven't installed is a cheap tray. SATA solves much of this issue, but you can still run into it. > I would not feel right trying to report this to RH > bugzilla. Is that something that has been done in the past? Yes. Any issue should be reported to Bugzilla -- Fedora Core or Red Hat Enterprise Linux (CentOS). In fact, I recently had a RHEL issue and Red Hat explicitly told me to run a newer Fedora Core version (with a newer kernel or set of kernel patches) to see if it fixed the problem. If so, then they'd integrate those fixes into the next RHEL update, or at least tell me what to patch in. > I am just really surprised that RH has not found this problem > on their own. 3ware controllers are used by a lot of users I > would think.

For the most part, knowing _how_ to deploy hardware or software RAID is the critical factor. If you use 3Ware, use its facilities. The biggest falicy I see propogated is that you can use its hot-swap and fault-tolerance with software RAID. You can't any more than any other ATA or SCSI card I've used (although I have to investigate some of the SCSI cards people are using here). If you need RAID-5 write performance, do _not_ use the 3Ware Escalade 7000/8000 cards. They only have a measly 1-4MB of 0 wait state SRAM (static RAM) and operate as a "storage switch" and are _not_ a "buffering controller." Consider RAID-10 instead, which it excells at, especially since it's write performance is far, far better than any RAID-5 write I've seen (software or hardware). A few people here are running the newer 3Ware Escalade 9500S cards with firmware 9.2.1.1, an updated driver to match (newer than what the stock/Red Hat kernels are running with) and RAID-5 with good results. I haven't personally used these, as I still prefer to deploy RAID-10 on the 8000 series. I've heard the 9550SX is still maturing. -- Bryan J.
