Capacity Planning

Capacity planning is the first step in capacity life cycle management. It provides a long-term view of resource requirements, and allows you to build an effective capacity management strategy.

To access the Capacity Planning view:

1
On the navigation panel, under Dashboards, click Capacity Director.
3
On the Menu bar, click the Getting Started tab.
The Getting Started view appears at the bottom of the Capacity Director dashboard.
4
On the Getting Started view > left pane, click Capacity Planning.
The Capacity Planning view appears on the right pane of the Getting Started view.

The Capacity Planning view provides a list of tasks that system administrators typically perform when planning the capacity of a virtual environment. Clicking a task directs you to the view where you can perform the selected task:

Trend and Forecast Host/Workload: Allows you to forecast number of servers needed in the future to support Virtual Machines based on organic rate of growth, or to forecast growth based on planned changes. Click this link to navigate to the Resource Utilization view > Hosts and Workload tab. For more information, see Clusters/Hosts and Workload pane.
Trend and Forecast Resource Utilization: Allows you to trend the resource consumption over time and forecast the resources utilization based on organic rate of growth or planned changes. Click this link to navigate to the Resource Utilization view > Clusters tab. For more information, see Clusters/Hosts and Workload pane.
Capacity and Time Remaining: Allows you to calculate the remaining capacity and time for CPU, Memory, Storage, and IOPs. Click this link to navigate to the Resource Utilization view > Clusters tab. For more information, see Clusters/Hosts and Workload pane.

Capacity Allocation

When the resources are in place, the next step is to create the environment and to allocate the available capacity to support the workloads.

To access the Capacity Allocation view:

1
On the navigation panel, under Dashboards, click Capacity Director.
The Capacity Director dashboard opens.
3
On the Menu bar, click the Getting Started tab.
The Getting Started view appears at the bottom of the Capacity Director dashboard.
The Capacity Allocation view appears on the right pane of the Getting Started view.

The Capacity Allocation view provides a list of tasks that system administrators typically perform when allocating resources in a virtual environment. Clicking a task directs you to the view where you can perform the selected task:

Plan Infrastructure Changes: Walks you through the process of modeling future changes (add, move, or remove virtual machines, hosts, and clusters) or plan infrastructure changes (add, move, or decommission virtual machines). Click this link to navigate to the Planned Changes view. For more information, see Changes and DRS Rules Tab.
Manage Scheduled Infrastructure Changes: Allows you to review the status of upcoming planned changes and modify the deployment date. Click this link to navigate to the Planned Changes view. For more information, see Changes and DRS Rules Tab.
Deploy Virtual Machines: Walks you through the process of creating and deploying a virtual machine. Click this link to navigate to the Add Virtual Machines Wizard. For more information, see Adding Virtual Machines.
Decommission Virtual Machines: Walks you through the process of decommissioning virtual machines that are no longer needed in your environment. The virtual machines are just turned off, but not deleted from the inventory. Click this link to navigate to the Decommission Virtual Machines Wizard. For more information, see Decommissioning Virtual Machines.

Capacity Optimization

Resource utilization can easily become unbalanced, as organizations and virtual environments grow over time. This leads to some clusters that are over-utilized, while others are under-utilized. The result is poor performance on the over-utilized clusters, and wasted resources and investment on clusters that are under-utilized. Optimal workload placement is critical to Return on Investment (ROI) in the virtual infrastructure. Foglight Capacity Director provides methods for both automatic and manual rebalancing of existing workloads, to ensure optimal resource utilization.

To access the Capacity Optimization view:

The Capacity Optimization view provides a list of tasks that system administrators typically perform for optimizing virtual environments. Clicking a task directs you to the view where you can perform the selected task:

Optimal Placement: Allows you to automatically rebalance the workload from clusters, by using an automatic algorithm that calculates and recommends the optimal distribution of virtual machines across clusters. Click this link to navigate to the Scenario Modeler > Optimal Placement view. For more information, see Optimal Placement.
Manual Placement: Allows you to manually rebalance the workload from clusters, by moving virtual machines between clusters. Click this link to navigate to the Scenario Modeler > Manual Placement view. For more information, see Manual Placement.

Capacity Maintenance

Foglight Capacity Director allows you to monitor fully functional and optimized datacenters, and proactively identify any short-term resource requirements, to ensure the system's continuous availability.

To access the Capacity Maintenance view:

The Capacity Maintenance view provides a list of tasks that system administrators typically perform for monitoring virtual environments. Clicking a task directs you to the view where you can perform the selected task:

Available Capacity: Allows you to review the available capacity on the system and identify any potential bottlenecks. Click this link to navigate to the Current Capacity view. For more information, see Current Capacity Tab.
Resource Utilization: Allows you to review the resources currently available in the system and identify potential bottlenecks. Click this link to navigate to the Resource Utilization view > Clusters tab. For more information, see Clusters/Hosts and Workload pane.
Slot Size: Allows you to configure the size of the virtual machine (the slot size) that Foglight Capacity Director uses in calculations for future planned changes. Click this link to navigate to the Current Capacity view. For more information, see Current Capacity Tab.
