EMC E20-555 - Isilon Solutions and Design Specialist Exam for Technology Architects
Which type(s) of data is predominately associated with home directories and file shares?
An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth.
Which tool would allow the customer to forecast capacity requirements?
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?
A customer has a cluster of 16 A200 nodes. Due to recent and forecasted growth, they have decided to
expand the cluster by an additional 24 A200 nodes.
How many neighborhoods will exist on the cluster when all nodes have joined the cluster?
If business objectives such as value and SLAs are considered, which Isilon license feature provides the ability to manage performance and the cost of data in a cluster?
A customer is running OneFS 8.0 on an Isilon cluster consisting exclusively of NL400 nodes. The storage administrator recently heard that OneFS 8.1 provides journal vaulting. What should you advise the storage administrator?
Your customer is looking for a storage solution that will be able to store seven million 3 MB files which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1 Gbps.
What would be the best solution for this network configuration?
A potential customer is considering replacing a four year old, Linux-based NFS server with 40TB of usable capacity. The existing system supports home directories, an internal website, and a content repository for the customer's content management system. The customer is concerned about performance of any new solution because they expect to double workload in the content management system.
What tools can be used to collect performance data needed to size the new solution?
An administrator recently installed InsightIQ to gather cluster statistics, and wants to look at file system usage (such as the number of files in a directory). However, currently no file system statistics are displayed in InsightIQ after 24 hours. Use of the cluster is moderate, and occurs 24 hours per day.
What job for InsightIQ should the administrator modify to successfully report these statistics?
Where does SmartCache stage its write cache?
