Installation guide

For Intel Xeon-based systems, the processors must include support for Intel Virtualization Technology
(VT). Many servers that include CPUs with VT support might have VT disabled by default, so you must
enable VT manually. If your CPUs support VT ,but you do not see this option in the BIOS, contact your
vendor to request a BIOS version that lets you enable VT support.
To determine whether your server has 64-bit VMware support, you can download the CPU Identification
Utility from the VMware Web site.
vCenter Server and vSphere Client Hardware Requirements
The vCenter Server system is a physical machine or virtual machine with access to a supported database. The
vCenter Server system must meet specific requirements. The vCenter Server machines must meet the hardware
requirements.
vCenter Server Hardware Requirements
Table 3-2. 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 Table 3-3.
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.
The recommended JVM heap settings for vCenter Server depend on your inventory size.
