LACP & NetApp 8020

[NovikovVladimir]

Hi!

We test perfomance storage NetApp 8020.

Configuration: 

- 2 x controller FAS8020 with 10Gb nic card

- 1 x disk shelf SAS

- 2 x disk shelves SATA (SATA + SSDdisk for FlashPool)  

Each controller is connected by 2 cables to Cisco Nexus.

This connection is configurable by EtherChannel or LACP 

Our results to CIFS share: ~ 7.5 Gb/s

This test showed that only one connection is used from the channel( EtherChannel/LACP)

Question - WHY? 

Please help

[SchlaerthMercy]

in your test, how many sessions (CIFS) are providing the load?  LACP will load balance across multipl,e interfaces, but if there is only a single session, it would traverse a single interface.  to test throughput and load balancing, you may want to leverage multiple sessions and multiple hosts to generate your network load.

SchlaerthMercy,

We tested for one and two source.

Results

One source: only one channel load and  speed connection 7 Gb/s

Two source: only one channel load and speed of one session from 3 to 4 Gb/s  (Sum of the speeds of both connections: 7 Gb/s )
