We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.

Your customer has an Isilon 4-node X400 cluster used for home directory use, and has since updated to OneFS 7.0. The HR and Legal departments have been very strict about using only dedicated file servers that are part of a single, isolated, untrusted Active Directory domain. Their filer has been out of maintenance, and fears are being raised that, due to the age, it may fail at some point.
What could the IT department do, to allow the HR and Legal groups to provide file share services, with minimal impact to their other application permissions?
In an Isilon cluster, what is the largest number of nodes that a single file can be striped across?
What is the correct order of steps taken during the file striping process?
An Isilon customer has an 8-node cluster of older X-Series nodes. They plan to upgrade the nodes over the next three years in the following stages:
At which point will a SmartPool license be required?
A customer is using file pool policies to archive infrequently accessed files to Amazon S3 via CloudPools. How
could the customer easily find out how many stub files are stored on the cluster?
What is an accurate statement when configuring an Isilon Gen 6 cluster with Compliance SmartLock?
A customer has two Isilon clusters. Cluster 1 has eight H500 nodes and cluster 2 has twelve H500 nodes. The
customer needs to be able to monitor real time performance data of the clusters as well as track file growth.
Which supported tool should be recommended?
A customer is considering moving their NAS data over to Isilon systems. They want to know what limitations Isilon has regarding snapshot on the directory level.
What explanation can be provided to the customer?
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?
You have received a critical task that requires immediate analysis of system performance. Captured data will later be processed by MiTrend, but a current assessment is not available.
Which utility will quickly provide IOPS associated with reads and writes, CPU utilization, and I/O scheduler wait time?
A customer has two data centers (Site A and Site B) and in each data center there is an Isilon cluster. They are replicating data between the sites using SyncIQ.

A customer wants an N+3 protection level on their cluster. What is the minimum number of nodes they need to achieve that level of protection?
When designing Isilon solutions, what issues should you pay special attention to?
While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?

A 6 × F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from
all the nodes in the ‘Data-Zone’ Access Zone. The ‘NFS-Pool’ with dynamic IP Allocation schema and ‘SMBPool’
with static IP Allocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the ‘NFS_Pool’. All the Windows clients are
accessing Isilon shares using SMBv3 via the ‘SMB_Pool’.

Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer’s environment.
The customer's current Isilon clusters are as follows:
“Cust” (12 x 12000X) serves as upload media storage for different tenants.
“Working” (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
“Archive” (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization.
