They are the MCE set of modules, which purportedly enable easy concurrency and parallelism, exploiting many core CPUs, and a number of techniques. Sure enough, I had a task to handle recently that … Read more

The worlds fastest hyper-converged appliance is faster and more affordable than ever

This is a very exciting hyper-converged system, representing our next generation of time series, and big data analytical systems. Tremendous internal bandwidths coupled with massive internal parallelism, and minimal latency design on networks. This unit has been designed to focus upon delivering the maximal performance possible in an as minimal footprint … both rack based … Read more
