On an Isilon cluster, how much space should be reserved for snapshots by default?

A hospital is considering using Isilon to store their archived medical images and Genomic Sequencing data. They currently have 56 TB of PACS images and 24 TB of genomic data, and expect to double their capacity requirements this year. They will replicate to a DR cluster, and plan to use N+2 protection. The production workload needs to be run at either site.

Which minimum cluster configuration, at each site, including software, would meet this customer's environment?

How many impact policy levels are available when configuring Isilon jobs?

Refer to the exhibit.

You are analyzing a customer's existing Isilon environment using InsightIQ in order to expand the cluster. When examining the protocol data, you see the output as shown.

What does the data tell you about the workload?

Which license is a prerequisite for enabling CloudPools?

A customer created one month of snapshots; one snapshot every 8 hours for 30 days on an Isilon cluster using SnapshotIQ. They are now deleting the snapshots randomly and experiencing overhead to the cluster.

How can the snapshots be removed while avoiding the overhead caused by this process?

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?

An Isilon customer is reporting less than expected performance from the cluster and poor space utilization. The customer is using three X400 nodes with N+2:1 protection policy to host webserver log data. Upon further analysis, it is discovered that the webservers write log files 64 KiB in size. The log files are then accessed by an analytics application for reporting.

What should be done to increase write performance of the cluster?

What are attributes of SFTP?

If Isilon SmartConnect is being configured in a customer environment, which records are required for a supported implementation?
