Lets go through some of the interesting clips from Steven Chapman’s Windows 8 article http://www.eyeonwindows.com/2011/02/24/steven-chapman-just-blew-my-mind-with-windows-8-data/
This was interesting
Worked on test tools/automation development for various core storage features of Windows 7 and Windows 8, including MPIO and storage CDB fuzzer.
MPIO and Storage CDB fuzzer eh?
What’s MPIO?
For those not in the know, multipath I/O is a fault-tolerance and performance enhancement technique whereby there is more than one physical path between the CPU in a computer system and its mass storage devices through the buses, controllers, switches, and bridge devices connecting them.
or
Multipathing, the ability of a system to use more than one read/write path to a storage device, is a high availability solution that provides fault tolerance against single-point-of failure in hardware components. Multipathing can also provide load balancing of I/O traffic, thereby improving system and application performance.
What’s Storage CDB?
The SCSI Command Descriptor Block (CDB) is a block of information that describes the command. Â Commands are sent from SCSI Initiators, which are contained in host computers, to SCSI Targets, which are controllers of some type of storage device (hard disk, tape drive, etc.)
