Dear Sirs. We expect to start a new FreeBSD driven server in Octobre based on a TYAN Thunder 2500-80 mainboard. This board uses the older version SymBios Logic 896 chip controler revision, I do not know whether the newer 1010 cips will work under FreeBSD. Due the effords in changing to a RAID 5 system I have some questions. TYAN offers on this board a PCI slot marked as RAID III port for cheap RAID solutions (including RAID 5). Has anybody experiences with such a "cheap" RAID solution, targeting performance, costs, reliability and stability? On the other hand, I'm looking for a worth-to-buy 2 channel SCSI-3/160 (PCI 64/66 Slot) RAID 5 controller. I saw some compatibility aspects for Mylex and ISP based controllers, but I never read anything about performance under FreeBSD. I maintain an older Server with a Mylex DPD960PD controller and this one is a litlle bit outdated and slow - but really reliable. Adatptec offers some RAID controllers based on newer SCSI-3/160 chipsets, but they seem to have a massive performance penalty compared to Mylex or others and I think they are only supported by Linux. If anyone con offer me some performance aspects, offer me some sites where to watch out what's offered in this area (RAID 5 based on SCSI-3/160), please contact me. Any information is appreciated. Thanks in advance, Gruss O.
