About IB-FLEX Instances and Flavor Settings
An IB-FLEX instance supports capacity-based licensing only, but it is compatible with NIOS Grid Master that uses node-based licensing. You can upgrade an IB-FLEX instance from a low-end flavor to a high-end flavor by increasing the resource allocation of the virtual machine. An IB-FLEX instance selects the default internal settings for a respective instance flavor based on the resource settings detected during the startup.
An IB-FLEX instance supports VMware ESXi with or without SR-IOV enabled and OpenStack with KVM both with or without SR-IOV. The table below provides information about the IB-FLEX platform resource specification:
