Server Hardware Requirements
Each Minimum ESXi hosting requirements are posted by VMware. VMware ESXi The minimum CPU Emulation Mode (EVC) recommended is Nehalem (problems have occurred when the EVC on the ESXi host is set to Penryn). Customized ESXi images for various server platforms are available on VMware and Hardware platform vendor sites. For more information, please visit the VMware Knowledge Base 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.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 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.
Ribbon Recommendations for Unable to show "metadata-from": No such page "_space_variables"
General Recommendations
- Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all the virtual machines (VMs) to run on the 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.
Additional Information
- Minimal networking configuration requires the Management Network Interface and at least one Media Interface to be assigned.
- Each SBC SWeLite VM will use approximately 5 GiB of Virtual Hard Drive space. Drive size is predetermined by the imported image.
