Explanation
FlexCache is a remote caching capability that simplifies file distribution, reduces WAN latency, and lowers WAN bandwidth costs. It enables distributed product development across multiple sites, as well as branch office access to corporate datasets. FlexCache only caches the actively-read data, rather than entire files or volumes, either locally within a datacenter or geographically dispersed at remote sites. This allows more data to fit in-memory, parallelize queries across hundreds of nodes, and index data faster. FlexCache can improve the speed and productivity of collaboration across multiple locations for read-intensive workloads such as content generation, movie rendering, chip-design, seismic analysis, and financial simulation.
