FlashSystem storage introduction

Flash technology in the data center is too relevant to be ignored for a few simple reasons:

•Since its introduction, flash storage has improved across all metrics: higher performance, density, and reliability, all of which translate to improved business efficiency.

•Flash cost per capacity and cost per transaction relative to hard disk storage make it extremely attractive to businesses that are attempting to maintain pace in a 24x7 competitive marketplace.

•Flash is easily integrated into existing data center environments ...
