Appendix C: Acronyms and abbreviations
Term Definition
Auto Port Speed**
Let VC automatically determine best Flex NIC speed
CLP String
Flex-10 NIC settings written to the server hardware by VC/OA when the server is power off. Read by
the server hardware upon power in.
Custom Port Speed**
Manually set Flex NIC speed (up to Maximum value defined)
DCC**
Dynamic Control Channel. Future method for VC to change Flex-10 NIC port settings on the fly
(without powering off)
EtherChannel*
A Cisco proprietary technology that combines multiple NIC or switch ports for greater bandwidth, load
balancing, and redundancy. The technology allows for bi-directional aggregated network traffic flow.
Flex NIC**
One of four virtual NIC partitions available per Flex-10 Nic port. Each capable of being tuned from
100Mb to 10Gb
Flex-10 Nic Port**
A physical 10Gb port that is capable of being partitioned into 4 Flex NICs
IEEE802.1Q
An industry standard protocol that enables multiple virtual networks to run on a single link/port in a
secure fashion through the use of VLAN tagging.
IEEE802.3ad
An industry standard protocol that allows multiple links/ports to run in parallel, providing a virtual
single link/port. The protocol provides greater bandwidth, load balancing, and redundancy.
LACP
Link Aggregation Control Protocol (see IEEE802.3ad)
LOM
LAN-on-Motherboard. Embedded network adapter on the system board
Maximum Link Connection Speed**
Maximum Flex NIC speed value assigned to vNet by the network administrator. Can NOT be manually
overridden on the server profile.
Multiple Networks Link Speed
Settings**
Global Preferred and Maximum Flex NIC speed values that override defined vNet values when multiple
vNets are assigned to the same Flex NIC
MZ1 or MEZZ1; LOM
Mezzanine Slot 1; LAN on Motherbard/systemboard NIC
Network Teaming Software
A software that runs on a host, allowing multiple network interface ports to be combined to act as a
single virtual port. The software provides greater bandwidth, load balancing, and redundancy.
pNIC**
Physical NIC port. A Flex NIC is seen by VMware as a pNIC
Port Aggregation
Combining ports to provide one or more of the following benefits: greater bandwidth, load balancing,
and redundancy.
Port Aggregation Protocol (PAgP)*
A Cisco proprietary protocol aids in the automatic creation of Fast EtherChannel links. PAgP packets
are sent between Fast EtherChannel-capable ports to negotiate the forming of a channel.
Port Bonding
A term typically used in the Unix/Linux world that is synonymous to NIC teaming in the Windows world.
Preferred Link Connection Speed**
Preferred Flex NIC speed value assigned to a vNet by the network administrator.
Share Uplink Set (SUS)
A set of Ethernet uplinks that are used together to provide improved throughput and availability to a
group of associated Virtual Connect networks. Each associated Virtual Connect network is mapped to a
specific VLAN on the external connection and appropriate VLAN tags are removed or added as Ethernet
packets enter or leave the Virtual Connect domain.
Smart Link
A feature that, when enabled, configures a Virtual Connect network so that if all external uplinks lose
link to external switches, Virtual Connect will drop the Ethernet link on all local server blade Ethernet
ports connected to that network.
Trunking (Cisco)
802.1Q VLAN tagging
Trunking (Industry)
Combining ports to provide one or more of the following benefits: greater bandwidth, load balancing,
and redundancy.
Trunking (Industry)
Combining ports to provide one or more of the following benefits: greater bandwidth, load balancing,
and redundancy.
VLAN
A virtual network within a physical network.
VLAN Tagging
Tagging/marking an Ethernet frame with an identity number representing a virtual network.
vNIC
Virtual NIC port. A software-based NIC used by Virtualization Managers
vNet
Virtual Connect Network used to connect server NICs to the external Network
*The feature is not supported by Virtual Connect.
**This feature was added for Virtual Connect Flex-10.
