I have a test box (PowerEdge 2950) with a Perc 6/i and 4x 15.5k SAS drives attached (with 512 byte block sizes). These are in a single RAID 5 virtual disk with a 64KB chunk size.
I am creating a single test partition that spans the whole drive. Should it be aligned to the 64KB chunk mark, or 512 byte block size? If the later, the partition could start at 2048 bytes into the single virtual disk, meaning it will begin at the 2nd free block on the first drive (I assume)?
Also, I will add another two drives and recreate the RAID virtual disk at a later date for more testing, should the partition then be created at 6x512 bytes, so from 3072 bytes?
I have read a couple of similar questions on this but I couldn't see from those, how the chunk size of the RAID volume might relate to partition alignment, on drive block size when using a single drive.
