Questions

1. Virtual Data Center – It's Not a Physical Data Center, Virtualized

Our journey into the virtual world

Not all "virtualizations" are equal

Virtual Machine – it is not what you think!

Software-Defined Data Center

The compute function

The network function

The storage function

All together now

A virtual data center versus a physical data center

Data center

Server

Storage

Network

Disaster Recovery

Application

Infrastructure team

Management disciplines impacted by virtualization

Summary

2. Capacity Management in SDDC

Shift in capacity management

Capacity management at the VM level

Capacity management at the infrastructure level

Capacity planning at the compute level

Capacity planning at the storage layer

Capacity planning at the network layer

Summary

3. Mastering the Key Counters in SDDC

First things first – the purpose

Compute

Network

Storage

Metric groups

VM – metric groups

ESXi – metric groups

Cluster – metric groups

Datastore – metric groups

Datastore cluster – metric groups

The distributed switch

Data center – metric groups

vCenter – metric groups

Counters in vCenter and vRealize Operations

When is a peak not a true peak?

vRealize Operations versus vCenter

Summary

8. Dashboard Examples and Ideas

Planning for your dashboards

Using the right counters

Figuring out who will use which dashboard

How many dashboards do I need to have?

Use case – is virtualization causing a problem?

What the dashboard looks like

Use case – managing the overall SDDC performance

VM level

Infrastructure level

Use case – dashboards for the big screen

Use case – storage performance management

Use case – storage capacity management

Use case – network performance management

Use case – right-sizing large VMs

What the dashboard looks like

Use case – capacity planning
