## Notes: 

GLYPH<SM590000> Important:  Using the ProtecTIER FSI as a network-attached storage (NAS), in terms of storing primary data directly to it, is not supported. ProtecTIER FSI must be used with an application that is supported by ProtecTIER. 

GLYPH<SM590000> Terminology:  This chapter uses the term bonding  when describing aggregating multiple network links to a single logical interface. You might have heard terms such as network aggregation , link aggregation , port trunking , trunking , link bundling , Ethernet bonding , network bonding , network interface controller (NIC) bonding , 802.3ad , or NIC teaming , which also describe the same concept. 

GLYPH<SM590000> Cabling:  Multiple members of a single bond must be connected to the same network switch. If you use multiple physically independent networks, similar to a dual-fabric approach in FC terms, you are required to have at least two bonds. Each bond must be cabled to only one network switch. 

## 3.1 Network terminology 

The following terms are relevant to network configurations in general: 

Bonding 

Teaming 

Trunking 

Bundling 

Link aggregation 

IEEE 802.3ad 

Gigabit Ethernet 

VLAN 

Host 

Bonding/Teaming 

A method for grouping several physical adapters into a single virtual adapter for load sharing, throughput enhancement, and redundancy enhancement. Bonding is the term that is typically used in Linux and UNIX operating systems. 

An alternative term for bonding, typically used in Microsoft operating systems. 

An alternative term for bonding or teaming. 

An alternative term for bonding or teaming. 

A method for grouping several interfaces into a single virtual interface for load sharing between the interfaces. Also known as network aggregation. 

Institute of Electrical and Electronics Engineers (IEEE) standard for link aggregation for LAN connectivity. 

Gigabit Ethernet (GbE) is Ethernet that runs in a gigabit per second (Gbps) bandwidth. 

Virtual LAN (VLAN) is a software defined LAN that groups network elements in the same broadcast domain. 

An entity that is connected to the network. For example, the NetBackup media servers are referred to as hosts. 

Teaming or bonding in servers, and link aggregation (802.3ad) or Cisco Ether Channel in LAN switches. The purpose of these mechanisms is to achieve higher bandwidth on the connection, as close as possible to the multiplication of the port bandwidth, along with redundancy between the ports.
