You have deployed an AFF 400 systems for ISCSI workloads and want to ensure maximum performance to the hosts.
In this scenario, which two steps should be configured? (Choose two)
A. Enable Jumbo frames on the network switch
B. Enable Jumbo frames on the LIF
C. Enable Jumbo frames on the broadcast domain
D. Enable Jumbo frames on the IPspace
Answer: A, C
Explanation:
Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of failure.
Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network performance substantially.
