What-If Analysis - Infrastructure Planning:
Traditional
You define scenarios that can
potentially add capacity to actual data centers or remove capacity from actual data centers.
VMware Aria
Operations
models the scenario
and calculates whether your desired workload can fit in the targeted data center or custom
data center. Where You Find Infrastructure

Infrastructure Planning: Traditional Works
Infrastructure Planning for traditional environments
lets you to forecast successfully the impact of adding capacity to your environment
or removing capacity from your environment. By trying various scenarios, you can
arrive at an optimum configuration. Once you select the Infrastructure Planning:
Traditional pane, you can choose where you want to locate the additional capacity or
from where you can remove the existing capacity.
In selecting the profile while removing capacity, you
can select a profile only from server types that exist in your cluster.
In selecting the profile while adding capacity, you
have two options:
- Select a server type from a list of commercially available servers. You can select from a list of 1) server types already in your cluster or 2) all server types approved for purchase.
- Configure a custom server manually by specifying CPU attributes, memory, and cost.
When you have set the profile for the new
server, enter the number of servers to purchase or remove and the start and end date
for the period when you want the scenario to be active. The number of servers that
you plan to remove is limited by the number of selected server types available in
the selected cluster. The system can project scenarios ending up to one year from
the current date. By default, the starting date is today and the ending date is one
year from today.
At this point, you can save the scenario to edit or
run later on. A list of saved scenarios is available on the What-If Analysis main
page. Otherwise, run the scenario to get the
VMware Aria
Operations
analysis
and assessment of your plan. The system displays immediately the impact on
cluster size of the additional or lesser amount of CPU and memory, and shows the
total cost of adding or removing the specified capacity. The system also shows
whether adding new capacity or removing capacity extends or shrinks the time
remaining before CPU or memory runs out.
As well, the system displays a graphic
depiction of resource use. For each attribute value - CPU and memory - the amount by
which the workload increases or decreases the percentage of total capacity used is
shown against a time line.
