2.7 Integrated Virtual Ethernet
Introduced with POWER6, POWER7 processor-based servers continue the use of IVE. The
terms IVE and HEA are sometimes used interchangeably, however, IVE encompasses all the
hardware parts including the HEA and the integration of several technologies.
IVE enables the ability to manage the sharing of the integrated HEA physical ports. The
PS700, PS701, and PS702 blades include two 1 Gb HEA ports on the base blade. The
PS702 has an additional two HEA ports on the expansion unit for a total of four physical ports.
Note: The PS700, PS701, and PS702 blades do not support the KVM function from the
AMM.
