Your Customer's Initial Use Case Was Home Directories

question 297

Multiple Choice

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?

• A) 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
• B) 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.
• C) Dual 10GbE ports on each node will enable throughput of 20Gbps. Only connect half of the nodes to the network.
• D) Isilon can support up to 400MB/s per node

Definitions:

Operationalization

Specific manner in which variables in a study are measured or manipulated.

Variables

Variables are elements, features, or factors that are liable to vary or change, often used in experiments to determine if they affect the outcome.

Independent Variable

In an experimental setting, the variable that is manipulated to observe its effect on a dependent variable.

Dependent Variable

In research, the variable that is being tested and measured, often seen as the effect in an experimental study.
