Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?
Response:

A. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system.FCoE should be considered for the External Network Ports on the nodes.

B. Maximum performance is obtained by only using a single 10GbE interface per node.LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system.

C. Maximum performance is obtained by only using a single 10GbE interface per node.Isilon can support up to 400MB/s per node

D. Dual 10GbE ports on each node will enable throughput of 20Gbps.Only connect half of the nodes to the network.
