Section 3 Planning Determine Required VMware ESX(i) Server Hardware
3BSE056141-510 F 23
Total disks: Each VM requires a separate physical disk of type SCSI or SAS to
optimize performance. The Domain Controller can be stored on the same disk
where the VMware ESX(i) server software is installed.
Total CPUs: It is recommended to have two virtual CPUs per virtual machine.
It is also recommended to have one logical processor in the hardware for each
virtual CPU in the virtual 800xA server nodes running on the VMware ESX(i)
server. For example, two QUAD core CPUs will support 8 VMs if each VM is
allocated one virtual CPU. On servers with Intel 5600 series processors of
model 5620 and above, the CPU also has hyper-threading. Hyper-threading
provides two logical processors per physical core and should not be considered
the equivalent of a CPU core since it shares CPU resources. However, this
provides more places for execution. If all physical CPU resources are in use, a
virtual machine may need to wait before it is provided access to the physical
CPU. Some versions of the CPU are 6 core processors instead of 4 core which
also increases the number of logical processors. Hence, a dual 6 core CPU will
provide 24 logical processors. In general the following should be observed:
In some cases, a virtual machine may have a work load that will require additional
virtual CPUs to be added to the virtual machine.
Total Network Interface Cards (NIC): One separate gigabit Ethernet port is
required for each physical network in which the VMware ESX(i) server should
Supported server models can be equipped with up to 16 disks. For higher
reliability, it is recommended to mirror disks using RAID 1. This leaves up to
eight productive disks for up to eight VMs per each VMware ESX(i) server.
Where the number of VMs exceeds the number of cores available, an additional
CPU, or ESX(i) server must be budgeted for. Licensing for ESX(i) 3.5/4.x server
is based on a per CPU cost. With the introduction of ESXi 5.0, licensing is based
on per CPU and amount of virtual RAM. Note that the ESXi 5.0 free version is
restricted to 32GB physical RAM. It is essential to confirm performance
requirements and to consider possible additional VMs, or increased workloads in
the future before using the virtualized system in production.
