I have the Enterprise 1400 Megaraid adapter with (currently 16M) on it. I have tested the various modes of operation (different raid levels and striping) and find it to be working well. My LVD array consists of 8 18G Quamtum IV's. Now... using vinum and either the 2940U2W (Adaptec LVD) or the TekRAM (NCR) LVD (using the sym0 device) gives 30 to 35 M/s under RAID-5. This is impressive and subject to the bug that I mentioned in -STABLE which still hasn't been found. The AMI MegaRAID 1400 delivers between 16.5 and 19 M/s (the 19M/s value is somewhat contrived --- using 8 bonnies in parrallel and then summing their results --- which is not 100% valid)... but the MegaRAID appears to be stable. I would like to know, however, if there are any planned or in-the-works utility programs for the amr device. In particular, a program to print the state of the array would be useful.
