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: 38  IBM ProtecTIER Implementation and Best Practices Guide Bonding 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. Teaming An alternative term for bonding, typically used in Microsoft  operating systems. Trunking An alternative term for bonding or teaming. Bundling An alternative term for bonding or teaming. Link aggregation A method for grouping several interfaces into a single virtual interface  for load sharing between the interfaces. Also known as  network aggregation. IEEE 802.3ad Institute of Electrical and Electronics Engineers (IEEE) standard for  link aggregation for LAN connectivity. Gigabit Ethernet Gigabit Ethernet (GbE) is Ethernet that runs in a gigabit per second  (Gbps) bandwidth. VLAN Virtual LAN (VLAN) is a software defined LAN that groups network  elements in the same broadcast domain. Host An entity that is connected to the network. For example, the  NetBackup media servers are referred to as hosts. Bonding/Teaming 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.
