We have a pair of scratch servers, each with a ccd stripe across 4 16GB IDE drives on Promise IDE cards(using the new ata driver). They're both running -current from about 2 months ago, and both have behaved flawlessly. Btw, they really perform well too, even when interoperating with NFS clients from other vendors. They can take NFSv3 writes from an Ultrasparc at nearly 100Mb/s wire speed. (10MB/sec). Try that w/linux ;-) Its really a shame we don't have NFS locking. If we had NFS server-side locking, we'd probably convert our home directories servers to FreeBSD servers with Vinum Raid-5. As it is, we're going to have to go with Solaris. Its really a shame, because on the same hardware, FreeBSD (w/Vinum Raid-5) runs circles around Solaris' disksuite software Raid-5.
