D-XTR-OE-A-24 Exam Dumps - EMC Storage Administrator Questions and Answers

VMware vStorage APIs for Array Integration (VAAI) offloads certain storage tasks from the ESXi host to the storage array.

When VAAI is disabled, operations like quick formatting can take significantly longer because the tasks are handled by the host instead of being offloaded to the array.

Quick formatting involves writing zeroes to the entire LUN, and without VAAI, this process is much slower.

Enabling VAAI allows the XtremIO array to handle these operations more efficiently, reducing the time required for tasks like formatting.

VMware VAAI Best Practices with XtremIO

In the XtremIO X2 WebUI cluster security settings, the available configuration options include LDAP, Login Banner, and Inactivity Timeout.

These settings provide administrators with the ability to manage user authentication, customize login messages, and set inactivity timeouts for enhanced security.

Configuring these options helps in maintaining a secure and compliant storage environment.

The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is:

Requestor interacts with the VSS service to start the backup

VSS service sends a Freeze request to the Writer

Provider creates an XVC of the file system and exposes the volume to the host

VSS service sends a Thaw request to the Writer

Requestor uses the XVC to back up the content of the volume

This sequence ensures that the backup is consistent and data integrity is maintained throughout the process.

A single XtremIO Management Server (XMS) can manage up to 8 X-Brick clusters.

For 20 XtremIO X1 clusters, the smallest number of XMS servers required to support the environment is 4.

Consolidating management operations to the minimum number of XMS servers helps in simplifying administration and monitoring tasks.
