what recommendations for a new Isilon cluster would you give to the customer based on this information?
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?
How can an Isilon cluster simplify a Hadoop workflow that analyzes large amounts of log data written to storag
How can an Isilon cluster simplify a Hadoop workflow that analyzes large amounts of log data
written to storage using FTP and where results are viewed by Microsoft Windows clients?
Which solution would you recommend to fit their capacity needs?
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 fivehundred 64kB metadata files associated with it. They currently have six years worth of archived
data. They will need to migrate to the new solution and they need to plan for an additional three
years of archive capacity.

What is the most important factor to consider when sizing this solution?
You are sizing an Isilon cluster for a new customer. Analyzing their workflow you determine that
they have a large block random read workload. What is the most important factor to consider when

How do you advise the customer?
A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in
order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters
leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized. They
also have multiple Fibre Channel SAN arrays in their environment.
They have a variety of workloads on each cluster and are in the process of determining which
workloads belong on which cluster. They have discovered that one of the workloads- a SQL
database that resides on the X-Series node cluster – is experiencing timeouts due to latency. The
database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts.

On Isilon node, where is caching for disk blocks staged?
Which configuration best fits the project requirements?
You are designing a new Isilon system to store mobile device video clips. The files average
800MB in size and the application team tells you to plan for up to 15,000 new files per day. The
product manager for this new service wants enough capacity for the first year and reminds you
that response time for storing and retrieving the files is important for customer satisfaction.
The files will be accessed frequently for the first 48 hours after creation, and then very infrequently
after seven days. You plan to use N+2:1 protection, and will configure a SmartPools policy to
move inactive files to an archive tier within the cluster.
Which configuration best fits the project requirements?
