comment Different block sizes for partition and underlying logical disk on HP Raid Controller (Linux)
Thanks again. I'm going to give all of them a try, just need to set up test environment.

comment Different block sizes for partition and underlying logical disk on HP Raid Controller (Linux)
Thanks for responses (and editing question -it looked as I didn't check it before sending). The goal is to find any possible performance improvement for our current cheap but not the most efficient system, without spending fortune, i.e. for building better RAID configuration. One of the line of attack is to tweak I/O elevator on the kernel level. i.e. there are suggestions that noop one may be better for box with raid controllers. That led me to looking more carefully on RAID configuration, blockdev output. I found some things I not fully understand and wanted to double check its meaning.

comment Is it worth to create one partion filling whole disk on Linux?
I prefer to have only necessary layers of software. Recently I've dived depper into I/O performance and started to wonder I got (or lost) anything with and without partition table, in situation where the whole disk was assigned to one partition. BTW When I was working with a lot of VMs I made LVM directly onto a 'disk' and put everything on it. I didn't have any problem, but wonder if it possible was just a luck.
