Enterprise flash: Three implementation options for virtualisation
This article is part of the IT in Europe issue of March 2012
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 ...

Features in this issue
Enterprise flash now comes in a variety of form factors aimed at speeding I/O beyond what’s possible with spinning disk in server and desktop virtualisation scenarios.
Solid-state storage has carved out a niche in the storage ecosystem, establishing itself as a viable alternative for high-performance applications.
Vendors tout dollars per gigabyte per I/O, but figuring out what a data storage system will really cost your company is a much more complicated process.
Data storage technologies keep getting better, but storage vendors may just be up to their old tricks.
Could the latest and greatest buzzword in the storage biz be killing off some of the most useful storage technologies around?
Cloud backup services have seen increased adoption by SMBs, but with a choice of methods and tighter controls, cloud backup is now also a viable enterprise alternative.
All the old standards -- FC, iSCSI and NAS -- are still going strong, but FCoE and virtualized I/O are waiting in the wings to help remake our storage networks.
