There is a need to carry out a tech refresh of an Isilon cluster. Old nodes must be removed because of space constrains in the data center. What methodology is least disruptive and will retain the file system structure, configuration, data, and DNS information?

1. A. Install the new nodes as a new cluster and use SyncIQ to replicate the data to the new nodes
2. B. Add the new nodes to the cluster and use SmartFail to move the data to the new nodes
3. C. Install new nodes into the cluster and use SyncIQ to replicate the data from the old to the new nodes
4. D. Install the new modes into the cluster and migrate using a host-based utility

Correct Answer: C

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?

1. A. SyncIQ and identical cluster at the DR site
2. B. SmartConnect and NL-Series nodes at the primary site
3. C. SyncIQ and NL-Series nodes at the DR site
4. D. Equal number of S-Series nodes at the primary site

Correct Answer: A

You are sizing an Isilon cluster for a new customer. Analyzing their workflow you determine that they have a large block random read workload.
What is the most important factor to consider when sizing this solution?

1. A. Bandwidth
2. B. IOPS
3. C. Latency
4. D. Headroom

Correct Answer: A

A customer requires a backup to tape of their Isilon cluster. They want advice on whether to implement a two-way NDMP solution or a three-way solution. The front-end network must be used to stream data to the backup solution. Which cost-effective solution will meet their needs?

1. A. Two-way including a Backup Accelerator
2. B. Three-way without a Backup Accelerator
3. C. Three-way including a Backup Accelerator
4. D. Two-way without a Backup Accelerator

Correct Answer: A

Traditional NAS storage architecture deploys simple two-way failover between two controllers in their storage systems, such as highly-available configurations. How is the Isilon architecture different in terms of system resiliency and availability?

1. A. Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.
2. B. Isilon solutions can enable failover to other nodes with the use of client-side drivers.
3. C. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
4. D. Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.

Correct Answer: D
