Configure the Disk to Install VCM on a Virtual Machine
Configure the disk for the virtual machine. For large scale environments, you might need to alter the
requirements.
Prerequisites
n Prepare the virtual machine to be used as a VCM Collector. See "Configure Resources to Install VCM
on a Virtual Machine" on the previous page.
n Keep the spindle count consistent and allocate a sufficient number of spindles to the database files when
you migrate VCM from a physical machine to a virtual machine.
n Place the database data files on multiple logical unit numbers (LUNs).
n Create a TEMPDB data file for each virtual CPU that is allocated to the VCM Collector.
n Use paravirtual SCSI (PVSCSI) controllers for the database disks to provide greater throughput and
lower CPU utilization, which improves VCM performance.
n Maintain a 1:1 mapping between the number of virtual machines and the number of LUNs on a single
ESX host to avoid disk I/O contention.
Procedure
1. Start vCenter Server.
2. Select your virtual machine.
3. Click the Resource Allocation tab.
4. In the CPU pane, click Edit.
5. In the Virtual Machine Properties dialog box, click the Resources tab.
6. In the Resource Allocation pane, click Disk and update the disk resource allocation to meet the needs
of your environment.
7. Click OK.

Configure the CPU for the virtual machine. For large scale environments, you might need to alter the

Prerequisites
n Prepare the virtual machine to be used as a VCM Collector. See "Configure Resources to Install VCM
on a Virtual Machine" on the previous page.
n Test the workload in your planned virtualized environment to verify that the physical CPU resources
on the ESX host adequately meet the needs of guest virtual machines.
n Provision multiple virtual CPUs only if the anticipated workload will use them. Over-provisioning
might result in higher virtualization overhead.
n Install the latest version of VMware Tools on the guest operating system.
