A company requires a cluster for deep archiving of data. Storage density is most important and high performance access is not a requirement.
Which node is recommended for this application?
- A . HD-Series
- B . NL-Series
- C . S-Series
- D . X-Series
Which SmartConnect policies are used for workloads that have short lived connections such as HTTP and FTP?
- A . Connection count and round robin
- B . Round robin and CPU usage
- C . Throughput and CPU usage
- D . Throughput and connection count
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?
- A . Configure SmartPools Advanced
- B . Add an A-series node with SmartPools license
- C . Enable FAST VP license on each node pair
- D . Install SmartPools license on the cluster
You are adding a new node to an existing cluster.
What OneFS function should you use to remove the old nodes from the cluster?
- A . SmartFail
- B . SyncIQ
- C . AutoBalance
- D . SmartPools
An Isilon customer is experiencing less than expected performance and poor space utilization with their cluster. They are using the X400 nodes with an N+2d:1n protection policy to host web server log data.
Upon further analysis, the customer discovers that the web servers write log files 64KiB in size. The log files are then accessed by an analytics application for reporting purposes.
What should be done to increase the write performance of the cluster?
- A . Change the protection scheme to a mirroring policy
- B . Add S-Series storage nodes to the cluster
- C . Add A-Series Performance Accelerator nodes to the cluster
- D . Change the SSD strategy on the cluster
A customer has 1,000 at 2 KB files, 5,000 at 4 KB files, and 4,000 at 7 KB files. They want to know the total amount of space on disk with a requested protection level of N+2d:1n.
How much on-disk space will be consumed for the data and protection overhead, excluding metadata?
- A . ~146 MB
- B . ~156 MB
- C . ~164 MB
- D . ~234 MB
Which Isilon tool can be run from the cluster to display Isilon statistics such as CPU activity?
- A . iperf
- B . iostat
- C . InsightIQ
- D . MiTrend
