It is important to note that due to the highly diverse scope of potential variations of virtual machine deployments it almost impossible to provide recommended hardware requirements.
Hardware requirements for the host device are dependent upon the number and roles of the virtual machines it will be managing. However, just like with any other computing device, the host hardware requires a…?
CPU, RAM, HDD storage, multiple NIC’s, and I/O device support.
The amount of processing ___ and ___ are going to be the main factors limiting the number of virtual machines that a host can support. Having a shortage in either can lead to a direct impact in performance of all VMs.
power and memory
No matter the brand, AMD, or Intel, it’s best to utilize a CPU that is optimized for virtualization. Both ADM and Intel produce CPUs equipped with virtualization extensions with this in mind; ___ and ___. This can greatly increase the performance efficiency of the host CPU.
AMD-V
Intel-VT
The amount of ___ utilized is a huge factor in performance of not only the host server, but of the VM’s as well.
RAM
The amount of ____ installed in the host will determine the amount of VM’s it can support.
memory
HDD storage, while not as crucial to system performance of the host server or VM’s, will also be a limiting factor to how many VM’s can be ____ and ____ on the host server.
stored and ran
What does NIC stand for?
Network Interface Card
What does HDD stand for?
Hard Disk Drive
The number of NICs will vary based on the desired tasks of the VM’s deployed on the host server. It is possible to operate a host server with two NICs, however the recommended amount is no less than ____ NICs for optimal network bandwidth and speed.
four
Just like with any traditional server or computer, the host server will need a means to interact with the user to make software and system configurations. This will be accomplished with use of input/output devices support. Examples:
mouse, keyboard and monitors
Most traditional host servers will be equipped with an on-board ___ ___ ___ (GPU) for a monitor to be connected. For host servers that do not have an integrated GPU, an adapter card will be required to be installed on the motherboard utilizing the PCI Express port.
graphics processing unit
A mouse and keyboard input devices will also be required for user interaction. Some servers still come equipped with an integrated PS/2 input port for a mouse and keyboard. However, all
servers today will have the capabilities for ___ ___ ___.
usb input devices
