A customer has an SMB file directory with 375 TB of data on the primary cluster with a protection level of N+3:1. They want to replicate this directory to the secondary cluster. They are interested in the possibility of setting protection levels on the target cluster.
Which target directory protection level information can be provided?

An Isilon cluster has four A200 nodes with 15, 12TB HDDs each. VHS is specified as four virtual drives or 15 percent of the node pool.
Which configuration would be used as reserved space for VHS?

What is a consideration when using SnapshotIQ?

A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.
The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.
The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for
30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.
In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.


The customer wants to be able to put completed content into a non-editable folder. However, they want to give access to an administrator to delete content if required.
What do you recommend to the customer?

You are designing an Isilon 5-node cluster configuration for a customer who wants to store user home directories on the new cluster. Each user has 100 small files of 4KB each, 100 medium sized files of 80KB each, and 100 larger files of 512KB each.
How much space is occupied by the medium sized files data blocks on an N+1n cluster?
