Description:

		This is the smallest unit the storage device can write

		without resorting to read-modify-write operation.  It is

		usually the same as the logical block size but may be

		bigger.  One example is SATA drives with 4KB sectors

		that expose a 512-byte logical block size to the

		operating system.

		This is the smallest unit a physical storage device can

		write atomically.  It is usually the same as the logical

		block size but may be bigger.  One example is SATA

		drives with 4KB sectors that expose a 512-byte logical

		block size to the operating system.  For stacked block

		devices the physical_block_size variable contains the

		maximum physical_block_size of the component devices.



What:		/sys/block/<disk>/queue/minimum_io_size

Date:		April 2009

Contact:	Martin K. Petersen <martin.petersen@oracle.com>

Description:

		Storage devices may report a preferred minimum I/O size,

		which is the smallest request the device can perform

		without incurring a read-modify-write penalty.  For disk

		drives this is often the physical block size.  For RAID

		arrays it is often the stripe chunk size.

		Storage devices may report a granularity or preferred

		minimum I/O size which is the smallest request the

		device can perform without incurring a performance

		penalty.  For disk drives this is often the physical

		block size.  For RAID arrays it is often the stripe

		chunk size.  A properly aligned multiple of

		minimum_io_size is the preferred request size for

		workloads where a high number of I/O operations is

		desired.



What:		/sys/block/<disk>/queue/optimal_io_size

Date:		April 2009

Contact:	Martin K. Petersen <martin.petersen@oracle.com>

Description:

		Storage devices may report an optimal I/O size, which is

		the device's preferred unit of receiving I/O.  This is

		rarely reported for disk drives.  For RAID devices it is

		usually the stripe width or the internal block size.
 
		the device's preferred unit for sustained I/O.  This is

		rarely reported for disk drives.  For RAID arrays it is

		usually the stripe width or the internal track size.  A

		properly aligned multiple of optimal_io_size is the

		preferred request size for workloads where sustained

		throughput is desired.  If no optimal I/O size is

		reported this file contains 0.
