Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient method for increasing the NAS system's network transmission throughput. The ALB software
continuously analyzes transmission loading on each adapter and balances the load across the teamed ports as needed. Adapter teams configured for ALB also
provide the benefits of adapter fault tolerance. To use ALB, the Ethernet ports on the NAS system must be linked to the same Ethernet switch.
Receive Load Balancing
Receive Load Balancing (RLB) is a method for increasing the NAS system's network throughput by allowing reception from multiple addresses. RLB can only be
used in conjunction with ALB, and only the Ethernet ports connected at the fastest speed will be use to load balance incoming TCP/IP traffic. Simultaneous
reception only occurs from multiple clients.
Switch Fault Tolerance
Switch Fault Tolerance (SFT) uses two Ethernet ports connected to two separate switches to provide network availability of a second switch and Ethernet port
if the first Ethernet port, its cabling, or the switch fails.
Adapter Fault Tolerance
Adapter Fault Tolerance (AFT) provides the safety of an additional backup link between the NAS system and the hub or switch. If a hub, switch port, cable, or
Ethernet port fails, you can maintain uninterrupted network performance. AFT is implemented with a primary adapter and a backup, or secondary, adapter. If
the link to the primary adapter fails, the link to the secondary adapter automatically takes over.
Intel Link Aggregation
Link aggregation is a performance technology developed by Intel® and others to increase a system's network throughput. Unlike ALB, link aggregation can be
configured to increase both transmission and reception channels between your system and switch. Link aggregation works only with compatible Intel
switches. To use link aggregation, the Ethernet ports of the NAS system must be linked to the same Intel Ethernet switch.
Fast EtherChannel and Gig EtherChannel
Fast EtherChannel (FEC) and Gig EtherChannel (GEC) use performance technology developed by Cisco Systems to increase a system's network throughput.
Unlike ALB, FEC can be configured to increase both transmission and reception channels between your NAS system and switch. FEC and GEC work only with
compatible Cisco switches. To use FEC or GEC, the Ethernet ports of the NAS system must be linked to the same Cisco compatible switch.
IEEE 802.3ad Static
IEEE 802.3ad is a performance technology standard that increases a system's network throughput. IEEE 802.3ad is similar to the FEC standard developed by
Cisco. However, whereas FEC works only with FEC-compatible Cisco switches, IEEE 802.3ad works with all switches that support IEEE 802.3ad. To use IEEE
802.3ad, the Ethernet ports of the NAS system must be linked to the same IEEE 802.3ad switch.
IEEE 802.3ad Dynamic
IEEE 802.3ad Dynamic is a performance technology standard that increases a system's network throughput. IEEE 802.3ad Dynamic uses active aggregators in
software to determine team membership between the switch and the server software or between switches. IEEE 802.3ad Dynamic mode requires 802.3ad
Dynamic capable switches.
