Question 1

What is the overhead impact on the physical capacity when configuring data protection at +2:1 on a 6-node Isilon cluster?

Accepted Answer

The +2:1 protection level means that two additional parity blocks are used for every data block, which translates to an overhead of 1/5 of the total capacity in a 6-node Isilon cluster.

Question 2

An Isilon customer wants to more effectively manage their storage and thereby achieve performance improvements. Which tool will help improve workflow performance on their cluster?

Accepted Answer

InsightIQ is a performance monitoring and reporting tool that helps in analyzing and optimizing the performance of Isilon clusters, thereby improving workflow performance.

Question 3

A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified. Which Isilon SmartLock version should they implement?

Accepted Answer

The Compliance version of Isilon SmartLock is designed to meet strict regulatory requirements by preventing any changes, deletions, or modifications to files, ensuring data integrity for the specified retention period.

Question 4

A customer has 10 nodes in a cluster using N+2 protection. What is the minimum number of nodes required to be online and in communication with one another to satisfy quorum?

Accepted Answer

In a cluster using N+2 protection, quorum is typically achieved with a majority of nodes. With 10 nodes, a majority would be more than half, which is 6 nodes.

Question 5

What is the minimum number of connected and available nodes required to maintain quorum in a 25-node Isilon cluster?

Accepted Answer

In an Isilon cluster, quorum is maintained when more than half of the nodes are available. For a 25-node cluster, more than half is 13 nodes.

Question 6

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

Accepted Answer

A SmartConnect Service IP host record and a zone delegation for the SmartConnect zone delegated to the SSIP are required for a supported implementation of Isilon SmartConnect.

Question 7

If business objectives such as value and SLAs are considered, which Isilon license feature provides the ability to manage performance and the cost of data in a cluster?

Accepted Answer

SmartPools is the Isilon license feature that allows for the management of performance and cost of data in a cluster by enabling tiering and balancing of data across different storage nodes.

Question 15

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

Accepted Answer

By default, Isilon clusters do not reserve any space specifically for snapshots, so the default reservation is 0%.

Question 18

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?

Accepted Answer

Deleting snapshots in the order they were created can help minimize the overhead on the cluster, as it allows the system to manage the snapshot data more efficiently.

Question 19

A customer is configuring Isilon SmartConnect. They have determined that their workload primarily consists of short-lived connections, such as HTTP and FTP. Which load-balancing policy provides the most efficient client distribution?

Question 20

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: Stage 1: Add 2 X-Series nodes to meet performance growth Stage 2: Add 4 NL-Series nodes to meet archive capacity growth Stage 3: Add 10 New X-Series nodes as a hardware refresh Stage 4: Remove older X-Series nodes At which point will a SmartPool license be required?

Accepted Answer

A SmartPool license is required when different node types (e.g., X-Series and NL-Series) are mixed in the same cluster to manage data across different performance tiers.
