Allocate multiple LUNs per host Use Thin formatting on the ESXi

Use consistent LUN numbers on each clustered host Use a 512 byte LUN sector size for databases

Use unique LUN numbers on each clustered host Use a 4 kB LUN sector size for databases

Allocate one large LUN per host Use Eager Zeroed Thick formatting on ESXi

Allocate multiple LUNs per host Use Thin formatting on the ESXi

What are the I/O Elevators?

1/O scheduling algorithm which controls how I/O operations are submitted to storage.

The maximum number of consecutive 'sequential' I/Os allowed to be submitted to storage.

Setting which controls for how long the ESX host attempts to login to the iSCSI target before failing the login.

The amount of SCSI commands (including I/O requests) that can be handled by a storage device at a given time.

How would a storage administrator navigate to different XtremIO clusters from the WebUl if the administrator has more than one cluster managed by the same XMS?

Click the Inventory List button on the Navigation Menu

Click on System Settings icon on the top Menu bar

Click the Administration tab and locate the Cluster Name

Click the Cluster Name on the Status bar at the bottom of the screen

Click the Inventory List button on the Navigation Menu

Suggested answer: C

Explanation:

In the context of Dell XtremIO storage arrays and their interaction with host systems such as Solaris, flow control is a network feature that manages data transmission and helps prevent packet loss when network congestion occurs. Enabling flow control on Solaris when it's connected to XtremIO arrays can be crucial for maintaining data integrity and ensuring smooth communication between the host and the storage system.

The Dell EMC Host Connectivity Guide for Oracle Solaris provides detailed instructions and best practices for configuring Solaris systems that are connected to Dell EMC storage arrays, including XtremIO1. While the document does not explicitly mention the setting to ''enable flow control,'' it is generally recommended to enable flow control in enterprise environments to manage data flow effectively and to prevent data loss or corruption during peak loads or network issues.

Enabling flow control can help in managing the pace at which data packets are sent, allowing the receiving device to handle the incoming data without being overwhelmed. This is particularly important in high-performance environments where XtremIO arrays are used, as they often handle large volumes of data transfers.

In summary, enabling flow control is a recommended practice for Solaris specific configurations when interfacing with Dell XtremIO storage arrays to ensure data transfer reliability and system stability.
