I have an iSCSI application which takes blocks of data from SCSI. I want the blocks to be as large as possible, atleast for me to see the performance of the iSCSI protocol. I intend to keep every thing in multiples of larger block sizes. Can I change it by changing the parameters in the kernel, like PAGE_SIZE(followed by block size) for ext2 ?(The approach seems very naive !!)
