When a Gen 6 Isilon cluster receives a file to be stored, which node(s) performs the FEC calculation?

When configuring Isilon SmartPools policies, which values are allowed for file pool policy storage destinations?

A customer is considering moving their NAS data over to Isilon systems. They want to know if the Isilon systems have any limitations regarding snapshots.
What explanation can be provided?

When designing Isilon solutions, what issues should you pay special attention to?

A customer plans to replace an existing array that is supported by the MiTrend Workload Profile Assessment (WPA) service. You receive performance data from the customer and run a WPA report that shows the array has 50TB of usable capacity.
In discussions with the customer, you learn the content is comprised of four million 6MB files and 400 million 64KB files. The customer explains they have a small budget and very limited rack space available in their datacenter. Performance is not a concern because the files are rarely accessed.
Which configuration provides the needed usable capacity using N+2:1 protection, and requires the least amount of rack space?

What replication option is NOT supported by SyncIQ?

Which Isilon SmartLock version uses an NTP server to keep track of the set retention periods placed on a directory?

What is the maximum number of data stripes in a Gen 6 Isilon?

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?

A customer has 10 nodes in a cluster using N+2 protection. What is the minimum number of nodes required to be online and in communication with one another to satisfy quorum?

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 sizing this solution?

A telecommunications company has a substantial amount of dat
a. This data is being created by network elements within their environment.
The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs.
After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.
Which protocols would be the best fit when using Isilon for this customer's Hadoop workflow?

A potential customer has 540TB Raw capacity of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload dat a. Their authentication sources are LDAP and Active Directory. Their users are primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tool(s) would you use next to complete your sizing?

If SmartPools is unlicensed on a cluster, which features are NOT enabled?
