EMC E20-555 - Isilon Solutions and Design Specialist Exam for Technology Architects

When an Isilon SyncIQ replication job completes, how many SnapshotIQ policies can be created on a target cluster directory?

A customer has a cluster consisting of six H500 nodes (in one full chassis and one half populated chassis) and

four A200 nodes (in one full chassis). The customer wants to expand their A200 nodes.

What is the minimum number of A200 nodes and chassis the customer can add to the cluster?

If snapshots are configured for the InsightIQ datastore on Isilon and the datastore is reverted to a previous snapshot, what might be the result?

You are asked to size a cluster for a file sharing environment. nfsstat indicates that 75% of the requests are namespace operations (e.g., GETADDR, SETADDR). There will be 8,000 active Linux users, connecting over NFS.

Which cluster configuration would you recommend?

At which level can retention periods be applied with Isilon SmartLock?

There is a concern that there are not enough physical switch ports available for the Isilon cluster in a new implementation with SMB and ICAP requirements. What course of action should be taken?

-- Exhibit --

A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.

The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.

The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.

The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.

In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.
