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.
