Dell MD3200i, MD3220i manual Configure the Storage Array Using PowerVault Mdcu

Page 41

Keep the following guidelines in mind for the storage array and host configuration:

For optimal performance, ensure your network configuration is valid by consulting the storage array's support matrix.

If your host has multiple network interfaces, it is recommended that each network interface uses a separate subnet.

For redundancy in a dual controller (duplex) configuration, ensure each host network interface is configured to connect to both storage array controllers.

For optimal load balancing, ensure each host network interface that is used for iSCSI traffic is configured to connect to each storage array controller.

It is recommended that each host network interface only establishes one iSCSI session per storage array controller.

NOTE: The utility tries to follow the guidelines for the host connectivity whenever possible based on the available host network interfaces and their connectivity with the iSCSI host ports of the storage array.

Configure the Storage Array Using PowerVault MDCU

To configure the iSCSI-based storage array(s) using PowerVault MDCU:

1Launch the utility (if it is not launched automatically) from the server with access to the management ports of the storage array(s) to be configured.

For Windows, click StartAll ProgramsDellMD Storage SoftwareModular Disk Configuration Utility.

For Linux, click the MDCU icon on the desktop or navigate to the /opt/dell/mdstoragesoftwaare/mdconfigurationutility directory in a terminal window and run PowerVault MDCU.

2Click Next to continue.

3Select the configuration task Configure Modular Disk Storage Array and click Next to continue.

4Select the method by which the utility should discover the storage arrays for configuration and click Next.
