Advanced vSphere 5.5 Performance Tuning

This three-day course covers vSphere 5.5 performance topics, aimed at the VMware professional. It is intended to be an extreme deep dive course. We offer internal lab systems, however we strongly suggest attendees have remote access to their infrastructure; real-world examples are best.

This course is led by an IVOXY Consultant that specializes in performance tuning, with at least five (5) years of experience as a virtualization consultant.

Prerequisite:  Hands-on vSphere

Course Length: 2 days (8am – 5pm).
