Which cluster configuration would you recommend?
You are asked to size a cluster for a file sharing environment. nfsstat indicates that 75% of the
requests are namespace operations (e.g., GETADDR, SETADDR). There will be 8,000 active
Linux users, connecting over NFS.

What would you do to help size this cluster?
A NetApp customer is considering Isilon. They use their filers for UNIX home directories, and
would like to see a suggested configuration that would meet their needs.

Which factors can demonstrate a lower TCO using Isilon?
A potential customer requires 800TB of usable capacity to store medical images for their network
of health clinics. The IT department has limited staff and currently manages four storage arrays
from other vendors. During a meeting with the Director of IT, you learn that the company is
planning to deploy a scale-out NAS solution from a competitor of EMC.
—-Which factors can demonstrate a lower TCO using Isilon?
Which cluster configuration would best meet these requirements?
A customer is looking for a NAS solution to support their read-intensive application.
This solution must meet the following requirements:
1000 users
Aggregate bandwidth of 5 GB/s
500 TB of user data
Typical latency of 5 ms.
The files are distributed evenly across 10 directories.

Which cluster configuration would best meet the customer’s requirements?
Your customer is looking for a storage solution that will be able to store seven million 3 MB files,
which are written and seldom accessed. Read and write operations are both completed by a webbased application, which requires 1.3 Gbps throughput. The customer’s network has not been
upgraded in many years, so the network interfaces are 1Gbps.

What would you recommend?
A customer wants to add Unix users to their cluster, and requires that NFS access be faulttolerant.

What could the IT department do, to allow the HR and Legal groups to provide file share services, with minimal
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?
What should be recommended for the backup solution?
You are designing a new Isilon cluster that requires backup to tape for all files in the Legal and
Accounting shared folders. The customer has sized their IP network to support the application
workload, but no additional bandwidth is available.
What should be recommended for the backup solution?
What should be done to correct this situation?
A customer’s cluster contains three X200 (24 GB RAM, 3 TB drives) nodes, and three X400 (48
GB RAM, 1 TB drives) nodes. All nodes are configured in a single pool. All data is protected at
N+2. After upgrading OneFS to 7.0, the Isilon Web interface indicates that files are not fully
protected.

What job for InsightIQ should the administrator modify to successfully report these statistics?
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.
