EMC E20-555 - Isilon Solutions and Design Specialist Exam for Technology Architects
A customer wants to use their large Gen 6 Isilon cluster for ILM. All of their data is written to and read from a single file pool. They need to use multiple file pools, so slightly used data is stored on less expensive, large disks. Heavily used data is stored on a faster tier.
What would satisfy the customer’s needs?
What key considerations should be kept in mind when designing a 300TB solution?
Your customer uses an existing Isilon cluster consisting of five NL-Series nodes to source broadcast media files for playback and streaming.The customer reports that the playback pauses and stutters regularly. It has been confirmed that there are no network or playback system issues.
Which of the choices listed is the appropriate choice to address the playback issues?
Which node type provides CPU, memory, and Fibre Channel connectivity?
You are called into an opportunity, you would like to get more information on the data skew of the filer. The customer has a supported filer.
What assessment tool would you use to generate this information?
A customer has a cluster running with a single access zone and serves multiple internal departments. The
clients access the cluster over both SMB and NFS protocols. A department user has been assigned the task of
auditing SMB activity and enforcing appropriate quotas for certain users.
How should the cluster administrator grant this access?
Which Isilon OneFS protection level allows you to withstand two drive failures but no more than one complete node failure?
How many layers are in the Isilon clustering architecture?
A hospital is considering using Isilon to store their long-term archive data for their GE PACS application. They currently have two million 17 MB studies. They expect capacity requirements to be 50% compounded growth per year. They plan to use N+2:1 protection, and would like this sized for three years of growth.
Which minimum cluster configuration would meet this customer's environment?
Which data access pattern uses moderate prefetching?
