Number of CPUs
Result
1vCPU
In an environment with an inventory of a few hundred
objects, the CapacityIQ views might render slowly because
of data collection, computation, and scheduled report
activities.
2vCPU
VMware ships with and recommends this number of CPUs.
4vCPU
The CapacityIQ environment can handle additional
concurrent users.
Allocating Memory for CapacityIQ
A new installation of the CapacityIQ appliance is configured with 3.6GB of RAM. To increase the number of
objects and the time range that CapacityIQ can analyze, add more RAM.
If the CapacityIQ appliance uses virtual machine version 7, the optimal amount of configured memory is 3GB
and any larger amount causes the guest operating system to utilize less memory. For information about virtual
machine versions, see the VMware vSphere documentation.
Allocating Disk Space for CapacityIQ
A new installation of the CapacityIQ appliance includes 8GB for the first hard disk and 250GB for the second
hard disk that stores CapacityIQ data.
Table 4-2
describes the data retention level that different amounts of
disk space support.
