I was not going to bother with this final Study Plan post, since all VCDX candidates should know this as their first port of call, however I wanted to provide a complete set of “VCDX Study Plan” posts.
Here is the Compute list (in no particular order, I typed them as they occurred to me):
- Rack versus Blade versus Hyperconverged (Nutanix/SimpliVity)
- NUMA and vNUMA – understand the difference and how it impacts your VMs
- Scale-Up or Scale-Out (Sockets, Cores and RAM)
- VMDirectPath – how can I use it to achieve 100% virtualisation?
- SR-IOV – how can I use this for sub-millisecond latency-sensitive apps?
- AMD or Intel
- Consolidation Ratios
- vCPU to pCore Ratios
- Peak GHZ utilisation
- Peak pRAM utilisation
- Failure Domains
- Cluster location and placement
- Who are the compute vendors? If I had a choice, who is the best for my design?
VMware vSphere (know these subjects like the back of your hand, this is the bedrock of VCDX, be prepared to deep dive into how it all works, regardless of how simple it is to configure):
- vSphere HA/vFT
- vSphere DRS/DPM and vMotion
- vSphere NIOC
- vSphere SIOC
- vSphere SDRS
- vCenter Server
- VAAI, VASA, VM Storage Profiles
- vSphere Integration Points
- Configuration Maximums
- Performance Best Practices
- Understand how vCOPs/vCNS/NSX/LogInsight etc. adds value/integrates with vSphere
