Installation guide

Depending on the size of your deployment, Update Manager requires a minimum amount of free space per
month for database usage. For more information about space requirements, see the VMware vSphere Update
Manager Sizing Estimator.
For more information about ESXi 5.x and vCenter Server 5.x hardware requirements, see Chapter 3, “System
Requirements,” on page 13.
Supported Operating Systems and Database Formats
Update Manager works with specific databases and operating systems.
The Update Manager server requires a 64-bit Windows system. The Update Manager plug-in requires the
vSphere Client, and works with the same operating systems as the vSphere Client.
Update Manager scans and remediates Windows and Linux virtual machines for VMware Tools and virtual
hardware upgrades.
The Update Manager server requires SQL Server or Oracle database. Update Manager can handle small-scale
environments using the bundled SQL Server 2008 R2 Express. For environments with more than 5 hosts and
50 virtual machines, create either an Oracle or a SQL Server database for Update Manager. For large scale
environments, you should set up the Update Manager database on a different computer than the
Update Manager server and the vCenter Server database.
