We are building a system with the following hardware: Tyan S2882 Dual Opteron Board (latest BIOS) 2 x Opteron 244 CPU's 2 x 1GB DDR PC3200+ LSI MegaRaid 150-6 (Intel SRCS16) (latest firmware) Intel Pro SC 1000 Fiber NIC 5 x 200GB 7.2KRPM 8MBuffer Western Digital (each hard drive has been checked for any problem) At first we started installing FreeBSD5.4-RELEASE AMD64 LSI Megaraid was detected and raid was running in optimal. When it asked me to choose the slice it gave me a warning that the geometry for the drive is incorrect and to check with the BIOS for the true geometry and if this is a SCSI please check with the controller's algorithem (something). Which I searched online for with no clues. Anyways went to system installation it starts installing bursting to 2600KB/s and after 55% it goes down to 800KB/s than when reaching ports it goes down to 33KB/s and this is CDROM installation!! When system is installed completly we ran dd on the system a constant average of 2.1MB/s is the BEST performance we could get! We tried installing Windows XP for testing and performance was decent bursting to 70MB/s (which is the average on this controller). We tried FreeBSD5.3(I386) and FreeBSD4.11(i386) same problem. Please if anyone have any idea whats going on we really don't wanna go with Linux on this system!! Thanks in advanced.
