Your customer has a new business unit. They are gathering web log files to be analyzed. They are using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on a 5-node Isilon cluster.
They have enabled the Hadoop cluster to access the files directly on the Isilon storage. The nodes are X400's with two SSD drives in each node and 96GB of RAM.
How many DataNodes does the Isilon cluster have?

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 6 F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from all the nodes in the 'Data-Zone' Access Zone. The 'NFS-Pool' with dynamic IP Allocation schema and 'SMBPool' with static IP Allocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the 'NFS_Pool'. All the Windows clients are accessing Isilon shares using SMBv3 via the 'SMB_Pool'.
While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.
What is recommended when creating a new IP pool for NFSv4 clients?

Refer to the exhibit.

A customer calls you and asks if you could come by and interpret their InsightIQ dat a. You see that namespace reads are 63% of the work load. What would you recommend to help this cluster's namespace performance?
