When the Internet emerged during the nineties, IP networks become the new core for electronic communications. Many proprietary standards and technologies died during each of these phases - such as the telegraph and, largely, the token ring. As cloud is transitioning into the mainstream, it's likely that the pattern will repeat. For cloud, data is key and so storage needs to evolve a new core architecture based on IP networking. Companies such as Google and Facebook recognized this new core approach and embraced it in their architectures. However, to reach the stage where storage is a standard core architecture akin to IP networks today, we must move well beyond today's hype. In the past two evolutions, there were always ... (more)

Preserving Storage I/O for Critical Applications

While server virtualization has unprecedented advantages, it has thrown some challenges as well. Prior to server virtualization, each application used to run on a dedicated server with dedicated storage connected through dedicated switch ports. Needless to say, this approach had multiple limitations in terms of lack of flexibility, underutilization, etc. But, it provided guaranteed hardware resources such as CPU, network, memory, and storage bandwidth for each application. With server virtualization, the underlying hardware resources are shared. Hypervisors do a good job in term... (more)
