IT is almost a foregone conclusion that when it comes to infrastructure, the industry will follow the lead of the big #hyperscalers and cloud builders, building a foundation of standardized hardware for serving, storing, and switching and implementing as much functionality and intelligence as possible in the software on top of that to allow it to scale up and have costs come down as it does. The reason this works is that these companies have complete control of their environments, from the processors and memory in the supply chain to the Linux kernel and software stack maintained by hundreds to thousands of developers. This task, as we have pointed out, is made much easier by the fact that what these companies are scaling up are buy a few handfuls of applications. Enterprises, by contrast, do not have these resources and this degree of control over their environments, and they have to rely on others to bring the software to market and support it for them. And not every application is going to be at a very high scale, so the compute and storage have to scale down as well as out. This is precisely what storage startup Excelero wants to do with flash storage. Forget disks. These are for companies that need to store exabytes of data. If you only need to store terabytes to petabytes, a compelling argument can be made for going all flash, and the NVMesh software that Excelero has created makes it relatively easy to create a pool of flash that is perhaps a better server-SAN hybrid than the other commercial products out there – particularly when it comes to latency and scale. And as the company’s product name suggests, NVM-Express is at the heart of the architecture of its clustered flash storage
