During the installation of VMware vSphere, a standard virtual switch
(vSwitch) is created. By default, vSphere chooses only one physical NIC as
a vSwitch uplink. To maintain redundancy and bandwidth requirements,
configure an additional NIC, either by using the vSphere console or by
connecting to the vSphere host from the vSphere Client.
Each VMware vSphere server should have multiple interface cards for
each virtual network to ensure redundancy and provide for the use of
network load balancing, link aggregation, and network adapter failover.
VMware vSphere networking configuration, including load balancing, link
aggregation, and failover options, is described in vSphere Networking.
Refer to the list of documents in Appendix C of this document for more
information. Choose the appropriate load-balancing option based on
what is supported by the network infrastructure.
Create VMkernel ports as required, based on the infrastructure
configuration:
VMkernel port for NFS traffic (NFS variant only)
VMkernel port for VMware vMotion
Virtual desktop port groups (used by the virtual desktops to
communicate on the network)
vSphere Networking describes the procedure for configuring these settings.
Refer to the list of documents in Appendix C of this document for more
information.
A jumbo frame is an Ethernet frame with a “payload” greater than 1,500
bytes and up to 9,000 bytes. This is also known as the maximum
transmission unit (MTU). The generally accepted maximum size for a jumbo
frame is 9,000 bytes. Processing overhead is proportional to the number of
frames. Therefore, enabling jumbo frames reduces processing overhead
by reducing the number of frames to be sent. This increases the network
throughput. Jumbo frames must be enabled end-to-end. This includes the
network switches, vSphere servers, and VNX SPs. EMC recommends
enabling jumbo frames on the networks and interfaces used for carrying
NFS traffic.
Jumbo frames can be enabled on the vSphere server into two different
levels. If all the portals on the vSwitch need to be enabled for jumbo
frames, this can be achieved by selecting Properties of the vSwitch and
editing the MTU settings from the vCenter. If specific VMkernel ports are to
be jumbo frame-enabled, edit the VMkernel port under Network Properties
from the vCenter.
