A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system. The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays.
Which tools can capture the workload requirements?

A customer's cluster contains three X200 (24 GB RAM, 3 TB drives) nodes, and three X400 (48 GB RAM, 1 TB drives) nodes. All nodes are configured in a single pool. All data is protected at N+2. After upgrading OneFS to 7.0, the Isilon Web interface indicates that files are not fully protected.
What should be done to correct this situation?

A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists of one hundred cases a day, each including fifty 60MB image files. However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived dat a. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity.
Which solution would you recommend to fit their capacity needs?

You have gathered information from your customer about their current NAS environment. They indicated they are having performance and time-out issues with their clients accessing the storage. Currently over 5000 clients are simultaneously accessing the NAS; however, this will double in the next year.
Based on this information, what recommendations for a new Isilon cluster would you give to the customer based on this information?

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?

While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?
