Question 12

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?

Accepted Answer

Journal vaulting is only supported on Gen 6 nodes.

Question 13

Which service daemon do FTP and FTPS use to transfer files to and from the cluster?

Accepted Answer

vsftpd (Very Secure FTP Daemon) is a popular FTP server for Unix-like systems, supporting both FTP and FTPS protocols.

Question 14

Question 15

What is the maximum number of data stripes in a Gen 6 Isilon?

Accepted Answer

The maximum number of data stripes in a Gen 6 Isilon is 128. This is a characteristic of the OneFS operating system used in Isilon storage systems, which allows for efficient data distribution and protection.

Question 16

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?

Accepted Answer

SyncIQ can be used to replicate data from the old nodes to the new nodes, while retaining the file system structure, configuration, data, and DNS information.

Question 17

What is an accurate statement when configuring an Isilon Gen 6 cluster with Compliance SmartLock?

Accepted Answer

The answer of What is an accurate statement when configuring...

Question 18

There is a concern that there are not enough physical switch ports available for the Isilon cluster in a new implementation with SMB and ICAP requirements. What course of action should be taken?

Accepted Answer

The customer needs to provide more switch ports to ensure that the Isilon cluster can meet the SMB and ICAP requirements effectively without compromising performance or connectivity.

Question 19

How many files can reference a single block within a shadow store?

Accepted Answer

A single block within a shadow store can be referenced by up to 32,000 files, allowing for efficient storage and retrieval in systems that use shadow copies.

Question 20

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?

Accepted Answer

The `iostat` utility provides quick statistics on IOPS (input/output operations per second) for reads and writes, CPU utilization, and I/O scheduler wait time, making it suitable for immediate system performance analysis.
