Table 7-1. Disk Space Requirements for Upgrading to vCenter Operations Manager 5.7
Resource Minimum Requirement
UI VM Disk 1: 4GB
Data Disks: 250GB
Analytics VM Disk 1: 4GB
Data Disks: 120GB
Add a Hard Disk to a Virtual Machine
You may need to add virtual disks to the UI VM and Analytics VM to support disk size requirements. Use the
vSphere Client to add a hard disk to a virtual machine.
For each virtual machine in the vApp that needs more disk space, add a new hard disk to the virtual machine.
You can add multiple disks as vCenter Operations Manager will mount and format all of them into the same
logical disk where vCenter Operations Manager data is stored.
Prerequisites
n
Verify that you have read the system requirements for vCenter Operations Manager upgrades. See
“vCenter Server and ESX Requirements,” on page 14 for details.
n
Verify that the vCenter Operations Manager vApp is powered off.
Procedure
1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.
2 Click the Hardware tab and click Add.
3 Select Hard Disk and click Next.
4 Select Create a new virtual disk and click Next.
a Type the disk capacity.
b Select a disk format.
n
Thick Provision Lazy Zeroed creates a virtual disk in a default thick format.
n
Thick Provision Eager Zeroed creates a type of thick virtual disk that supports clustering features
such as Fault Tolerance.
n
Thin Provision creates a disk in thin format. Use this format to save storage space.
NOTE Thick provisioned eager-zeroed format provides about a 10 percent performance improvement
over the other two disk formats. VMware recommends that you select the thick provisioned eager-
zero option when possible.
NOTE Snapshots can negatively affect the performance of a virtual machine and typically result in a
25-30 percent degradation for the vCenter Operations Manager workload. VMware recommends that
you do not use Snapshots.
c If you specify a datastore, browse for the datastore location, and click Next.
5 Accept the default virtual device node.
6 Click Next.
7 Review the information and click Finish.
8 Click OK to save your changes and close the dialog box.
