Hope this helps (not sure if it was necessary, but sometimes I like to go a little over the top. Now in reality it is a little more complicated than this, but this kinda gives an insight into the way the whole bloc-size thing works. Now I am asked for 'ABCD', and all 4 disks get involved. Basically if I ask for 'A', this can only come from disk 1, and no other disk is involved.īut if I ask for (stripe size * number of disks) worth of data, I force every drive in the array to give me something, and the maximum sequential speed can be determined. Now if I only ask for 128KB of data each time, all of that must come from a single drive - the array will appear to be only as fast as a single disk, as each transfer only comes from 1 drive. In this case A would be 128KB, B = 128KB, etc.

Now each letter is a single stripe-worth of data (A, B, C, etc), meaning ABCD is a full stripe width. Say for example if I have the data ABCDEFGH on my 4-disk striped RAID0 array as such:
Just in case people are confused by what Manyak has said here - basically, if you use too small of a block size, all of the data that the benchmark program requests from the drives comes from a single disk, rather than being requested from the array as a whole. I have a flashed H200 in a H710, you can enable/disable the storage rom within the R710's Bios config. I have a LSI 9211-8i and it behaves in that way at least.

People don't know how to use it, and end up either confused or optimising for the wrong settings for best performance. IT mode turns the controller into a dumb HBA that only serves as a communication medium between OS and disks attached to it. I've said it before, and I'll say it again - disk benchmark software often causes far more problems than it solves. If problems persist contact Tech Support.Īny ideas? I'd be really bummed if I pin mod'd and destroyed a 100$ card Please check the RAID Key installed for this solution. however i end up with this error before I can get into the BIOS: The system posts and i can access the BIOS settings etc etc.

I did the SMBus pin 5&6 mod as seen here: The card stays SUPER cool with this setup, and it's not very loud at all. I ripped out the retaining clip from the stock perc heatsink and put it on the little falls heatsink. a replacement heatsink for the little falls mainboard linky a 40mm x 10mm fan (i just had one from an old intel atom mainboard I'm not using) I also have some troubleshooting questions that hopefully someone can help out with.įirst of all here's a couple photos of what I did to manage the heat on this card. I thought I'd post up some pics of my heatsink mods. I'm planning to run 4 x MLC drives with that infamous JMF602 controller on a dell perc5/i like so many people do.
