vSphere Flash Read Cache (vFRC)
Recently I started studying for my second VMware VCAP exam. It made sense to plan the updated VCAP550-DCA exam, since vSphere 5.5 is among us for quite some time now.
While doing so, you automatically run into vSphere Flash Read Cache (vFRC). A feature provided since vSphere 5.5 (only in the Enterprise+ bundle), but I never got to configure and/or test it. Hence this little write-up…
Running through the blueprint for VCAP550-DCA, you’ll see it listed under section 1, objective 1.1:
Section 1 – Implement and Manage Storage
Objective 1.1 – Implement Complex Storage Solutions
