This is the second part in a two-part series comparing Virident’s vCache to FlashCache. The first part was focused on usability and feature comparison; in this post, we’ll look at some sysbench test results.
Disclosure: The research and testing conducted for this post were sponsored by Virident.
First, some background information.
