Performance considerations for efficient data storage
At the end of the day, storage performance issues need to be addressed sensibly and strategically. Optimizing IOPS is part of the equation, but so is ensuring that I/O traffic is balanced across the myriad pathways, usually a mix of Fibre Channel cabling and switching, iSCSI networking and direct-attach configurations. And, of course, implementing some means of spotting and resolving performance problems is key.
This video looks at storage performance efficiency and why it shouldn't be considered in isolation from the other dimensions of storage efficiency.
