I support a non profit. They got an ML350 G5 donated to them and I immediately put it to good use for them :) It came with four HP 300GB 15K SAS drives - and of course, they have all now failed. I have been replacing the drives and they are all 6Gb/s drives, but the HP controller in the ML350 is a 3Gb/s controller. I have a nice 8 port LSI MegaRAID SAS controller sitting here with battery backup and everything - can I just swap out the controllers and expect everything to work?
I haven't found much about the differences between 3 and 6 Gb/s SAS interface from a physical layer. As near as I can tell, it should work just fine. I'm just curious if anyone has any experience doing this.
I'm not hung up on the drives being hot swappable, so if not I may just see if I can physically alter the case, toss the HP drive cage and stuff a different cage or mounting system in there to accommodate the better controller with the newer drives.
Ugh - now I remember why I prefer white box servers for one-off or small business vs. the "big boys" like HP, Dell, etc...
And anyone have a good source for rails for this thing? The HP prices are ridiculous - I could build another server for what they want for rails!
