Access "Enterprise flash: Three implementation options for virtualisation"
This article is part of the March 2012 issue of Finding a home for Flash
Enterprise flash storage is being bought in increasing numbers, and new enterprise flash products are emerging from vendors old and new to meet that demand. The key drivers in the enterprise flash market are a combination of the falling cost of flash memory, which is making solid-state disk an increasingly economic proposition, and lagging spinning disk performance, which has become the bottleneck in many data centres. That bottleneck is largely a result of the demands of server and desktop virtualisation, which can generate large volumes of random I/O from a single host. In addition, some database tasks can provide similar challenges, requiring large volumes of throughput. Spinning disk struggles to cope with such demands, to which the solution was often to add more disk. This increases throughput, especially if you short-stroke drives. However, this increases heat levels and power consumption and means buying much more capacity than you actually need to satisfy throughput requirements. Enterprise flash technology ameliorates the problem by providing ... Access >>>
