Minimum Hardware Requirements for vCenter Server System
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.
Minimum Hardware Requirements for vCenter Single Sign On, Running on a Separate Host Machine from vCenter Server
| vCenter Single Sign On Hardware |
Requirement |
| Processor | Intel or AMD x64 processor with two or more logical cores, each with a speed of 2GHz. |
| Memory | 3GB. Memory requirements might be higher if the vCenter Single Sign On database runs on the same host machine. |
| Disk storage | 2GB. Disk requirements might be higher if the vCenter Single Sign On database runs on the same host machine. |
| Network speed | 1Gbps |
Minimum Hardware Requirements for vCenter Inventory Service, Running on a Separate Host Machine from vCenter Server
| vCenter Inventory Service Hardware |
Requirement |
| Processor | Intel or AMD x64 processor with two or more logical cores, each with a speed of 2GHz. |
| Memory | 3GB. |
| Disk storage | At least 60GB for medium- to large-sized inventories (more than 100 hosts or 1000 virtual machines). |
| Network speed | 1Gbps |
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 | The amount of memory needed depends on your vCenter Server configuration. | |
| ■ | If vCenter Server is installed on a different host machine than vCenter Single Sign On and vCenter Inventory Service, 4GB of RAM are required. | |
| ■ | If vCenter Server, vCenter Single Sign On and vCenter Inventory Service are installed on the same host machine (as with vCenter Simple Install), 10GB of RAM are required. | |
| Memory requirements are higher if the vCenter Server database or vCenter Single Sign On database runs on the same machine as vCenter Server. | ||
| Disk storage | The amount of disk storage needed for the vCenter Server installation depends on your vCenter Server configuration. | |
| ■ | If vCenter Server is installed on a different host machine than vCenter Single Sign On and vCenter Inventory Service, 4GB are required. | |
| ■ | If vCenter Server, vCenter Single Sign On and vCenter Inventory Service are installed on the same host machine (as with vCenter Simple Install), at least 40-60GB of free disk space are required after installation, depending on the size of your inventory. 100GB are recommended, to allow for future growth of your inventory. | |
| Disk storage requirements are higher if the vCenter Server database or vCenter Single Sign On database runs on the same machine as vCenter Server, depending on the size of those databases.In vCenter Server 5.x, 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. | |
| Network speed | 1Gbps | |
