Specifications

Table 3‑15. Minimum Hardware Requirements
Hardware Requirements
Processor Intel or AMD x86 processor with two or more logical cores, each with a speed of 2GHz
Network 10/100 Mbps
For best performance, use a Gigabit connection between Update Manager and the
ESX/ESXi hosts
Memory 2GB RAM if Update Manager and vCenter Server are on different machines
4GB RAM if Update Manager and vCenter Server are on the same machine
Update Manager uses a SQL Server or Oracle database. You should use a dedicated database for
Update Manager, not a database shared with vCenter Server, and should back up the database periodically.
Best practice is to have the database on the same computer as Update Manager or on a computer in the local
network.
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.
NOTE Make sure the system on which you are installing Update Manager server is not an Active Directory
domain controller.
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.
