system may not behave as expected.

Server Hardware Requirements

Hardware Requirements

Configuration	Requirement
Processor	2nd Generation Intel Core or Intel Xeon Processor (Sandy bridge or later)
Host OS	ESXi 5.5 or above
Architecture	64-bit Intel processor
RAM	RAM requirements are dependent upon the number of VMs hosted, the memory assigned to each VM instance, and the relative overhead memory associated with each.
Datastore	Hard disk requirements are dependent upon the number of VMs hosted, the size of each VM at full size, and whether snapshots will be enabled.

Platforms using AMD processors are not supported.

Minimum ESXi hosting requirements are posted by VMware.

Customized ESXi images for various server platforms are available on VMware and Hardware platform vendor sites.

It ensures that all the required drivers for network and storage controllers are available to run ESXi server.
Most of the customized ESXi images comes with customized management software to manage server running ESXi software.
Customized ESXi images for HP ProLiant and IBM servers are available at:

Refer to VMware Compatibility Guide (external site) for a list of VMware supported Intel processors.

Refer to ESXi hardware requirements to ensure the VMware supported Intel processors meet ESXi hardware requirements.

Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all the virtual machines (VMs) to run on server platform, including resources needed by ESXi itself.
Allocate each VM with only as much virtual hardware as that VM requires. Provisioning a VM with more resources than it requires can, in some cases, reduce the performance of that VM as well as other virtual machines sharing the same host.
Disconnect or disable any physical hardware devices that you will not be using (floppy drives, network interfaces, storage controllers, optical drives, USB controllers, etc.) under BIOS settings to free up interrupt/CPU resources.

VM Configuration Recommendations

The SBC SWeLite VM does not currently support allocation of more than one vCPU.
With minimum RAM allocation, the maximum SIP endpoint registrars is 1000, and the maximum number of concurrent calls is 100.
The estimated ESXi overhead memory for each SBC SWe Lite Virtual Machine is 30MB.
Minimal networking configuration requires the Management Network Interface and at least one Media Interface to be assigned.
Each SBC SWeLite VM will use approximately 5GB of Virtual Hard Drive space. Drive size is predetermined by the imported image.
