vSphere Installation and Setup Table 2‑3. 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. If vCenter Single Sign-On runs on the same host machine as vCenter Server, see Table 2-2 or Table 2-5. Disk storage 2GB. Network speed 1Gbps Table 2‑4. 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. If vCenter Inventory Service runs on the same host machine as vCenter Server, see Table 2-2 or Table 2-5. Disk storage If vCenter Inventory Service runs on the same host machine as vCenter Server, these requirements are in addition to the disk space required for vCenter Server and any other applications running on the vCenter Server host machine. See Table 2-5. Disk storage requirements for Inventory Service depend on inventory size and the amount of activity in the virtual machines in the inventory. At typical activity rates, Inventory Service uses 6GB - 12GB of disk space for 15,000 virtual machines distributed among 1,000 hosts. A high rate of activity (more than 20 percent of your virtual machines changing per hour) results in write-ahead logs (WAL) being written to disk to handle updates, instead of in-line writes into existing disk usage. This high rate of activity is often associated with Virtual Desktop Infrastructure (VDI) use cases. In the following guidelines for required disk space, a small inventory is 1-100 hosts or 1-1000 virtual machines, and a large inventory is more than 400 hosts or 4000 virtual machines. n Small inventory, low activity rate: 5GB. n Small inventory, high activity rate: 15GB. n Large inventory, low activity rate: 15GB. n Large inventory, high activity rate: 40GB-60GB. Network speed 1Gbps Table 2‑5. 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. 18 VMware, Inc.
