Foundation leaves these unset when imaging. They raise the MTU past the normal 1,500 bytes to as much as 9,000 for guest VMs and physical host interfaces, though the CVM keeps 1,500.

Each book explains Jumbo frames in context, with comparison tables and the common traps.
Terms in this definition
- Foundation
Nutanix's own tool for building clusters, loading nodes first with AOS and a hypervisor that are supported together. Its three forms are the standalone VM, the app and the version in the CVM.
- MTU
Biggest frame an interface can carry. The physical fabric needs at least 1600 bytes for NSX overlay traffic, with 1700 recommended and 9000 preferred where jumbo frames run end to end.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- Physical
Describes the concrete, real-world parts that put a logical architecture into effect.
- CVM
A VM required on the hypervisor of every node in a Nutanix cluster, with AOS as its operating system. Every one needs a static IP address of its own.
Related terms
- Dependency
Anything the design needs that is provided by a different team, vendor or system and lies outside its control, for example corporate DNS and NTP, a witness site or jumbo frames end to end. Each should be confirmed and tracked, since a dependency that may not arrive is a risk.
