EMC Updated E20-555 Exam Questions and Answers by solomon

Refer to the exhibit.

You are analyzing a customer’s existing Isilon environment using isi statistics in order to expand the cluster. When examining the protocol subcommand, you see the output as shown in the exhibit.

What does the data tell you about the workload?

How many file systems are present in a 20-node Isilon X200 cluster?

A customer wishes to back up their Isilon cluster via NDMP using a software package that supports NDMP

connectivity. The backup process will require the cluster to create a point-in-time copy of the directory to be

backed up.

Which OneFS feature(s) will need to be licensed?

Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer’s environment.

The customer's current Isilon clusters are as follows:

“Cust” (12 x 12000X) serves as upload media storage for different tenants.

“Working” (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.

“Archive” (16 x 72NL + Accelerator nodes) is used to store printed content for six months.

The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization.

The requirements for this solution include:

• Better ROI and TCO
• Maintain same performance with possible improvements
• Renew HW/SW and get inclusive support
• Limit migrations
• Reduce space, power, cooling consumption
• Get new feature sets
• If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections)
• Segregate tenant shares from other tenants
• Expand up to 1PB of total storage

What would you recommend be done to consolidate the three clusters into one?
