Bonding o Teaming

sr_meck dijo:

Depende de que protocolo vas a lacp o pagp y esa wea tiene que estar configurado x ambos lados para que funcione.

Ahora si no me equivoco el teaming por el lado de los server lo único que hace es dejar una activa y la otra standby… el bonding une ambas como una para usar todas la capacidades y ahí depende si es lacp o pgap

Ya, configuré la huea en bonding con esto

Dynamic Link Aggregation

aggregated NICs act as one NIC which results in a higher throughput, but also provides failover in the case that a NIC fails. Dynamic Link Aggregation requires a switch that supports IEEE 802.3ad.

Oye @sr_meck , ¿que un switch soporte IEEE 802.3ad es algo normal o es una excentricidad?

Al final configuré el bonding en modo active-backup nomás y sin lacp, tal como recomiendan las buenas prácticas de Oracle.

2.1.1 About Network Bonding

Multiple physical network interfaces that are present on a system and that are connected to a network switch, can be grouped together into a single logical interface to provide higher throughput or availability. This grouping, or aggregation, of physical network interfaces is known as a network bond.

A bonded network interface can increase data throughput by load balancing or can provide redundancy by allowing failover from one component device to another. By default, a bonded interface appears like a normal network device to the kernel, but it sends out network packets over the available slave devices by using a simple round-robin scheduler. You can configure bonding module parameters in the bonded interface's configuration file to alter the behavior of load-balancing and device failover.

The network bonding driver within the kernel can be used to configure the network bond in different modes to take advantage of different bonding features, depending on your requirements and your available network infrastructure. For example, the balance-rr mode can be used to provide basic round-robin load-balancing and fault tolerance across a set of physical network interfaces; while the active-backup mode provides simple fault tolerance for high availability configurations. Some bonding modes, such as 802.3ad, or dynamic link aggregation, require particular hardware features and configuration on the switch that the physical interfaces connect to. Basic load-balancing modes (balance-rr and balance-xor) work with any switch that supports EtherChannel or trunking. Advanced load-balancing modes (balance-tlb and balance-alb) do not impose requirements on the switching hardware, but do require that the device driver for each component interfaces implement certain specific features such as support for ethtool or the ability to modify the hardware address while the device is active.
