Make sure that your run vCenter Server on a machine that meets the requirements for the VSA cluster.

You can install vCenter Server on a physical server or on a virtual machine. Make sure that the machine that you choose meets the vCenter Server hardware requirements to operate in a VSA cluster. If you choose to run vCenter Server on a virtual machine, that virtual machine cannot be hosted on an ESXi host that is running a vSphere Storage Appliance.

Minimum Hardware Requirements for vCenter Server

vCenter Server Hardware

Requirement

CPU

Two 64-bit CPUs or one 64-bit dual-core processor.

Processor

2.0GHz or faster Intel 64 or AMD 64 processor. The Itanium (IA64) processor is not supported. Processor requirements might be higher if the database runs on the same machine.

Memory

4GB RAM. Memory requirements might be higher if the database runs on the same machine.

vCenter Server includes several Java services: VMware VirtualCenter Management Webservices (Tomcat), Inventory Service, and Profile-Driven Storage Service. When you install vCenter Server, you select the size of your vCenter Server inventory to allocate memory for these services. The inventory size determines the maximum JVM heap settings for the services. You can adjust this setting after installation if the number of hosts in your environment changes. See the recommendations in Recommended JVM Heap Settings for vCenter Server.

Disk storage

4GB. Disk requirements might be higher if the vCenter Server database runs on the same machine. In vCenter Server 5.0, the default size for vCenter Server logs is 450MB larger than in vCenter Server 4.x. Make sure the disk space allotted to the log folder is sufficient for this increase.

Microsoft SQL Server 2008 R2 Express disk

Up to 2GB free disk space to decompress the installation archive. Approximately 1.5GB of these files are deleted after the installation is complete.

Networking

Gigabit connection recommended.
