1. A. Use LACP to aggregate the network ports on each node.
2. B. Use jumbo frames to compensate for the 1GB Core network.
3. C. Aggregate Infiniband (IB) ports across all nodes.
4. D. Bond EXT-0 across all nodes.

Correct Answer: A

Correct Answer: D

A potential customer has 540TB Raw capacity of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. Their authentication sources are LDAP and Active Directory. Their users are primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tool(s) would you use next to complete your sizing?

1. A. MiTrend WPA, Autosupport, and PerfCollect
2. B. Isilon Cluster Sizing Tool
3. C. Wireshark, isi statistics, and iostat
4. D. Isilon Insight IQ, OnCommand Insight, and nfsstat
