6Click OK to exit the Advanced menu and click OK again to exit the Add Target Portals screen.

7To exit the Discovery tab, click OK.

If you plan to configure CHAP authentication, do not perform discovery on more than one iSCSI port at this point. Go to "Step 4: Configure Host Access" on page 62.

If you do not plan to configure CHAP authentication, repeat step 1 thorough step 6 for all iSCSI ports on the storage array.

If you are using Windows Server 2008 Core Version:

1Set the iSCSI initiator service to start automatically:

sc \\<server_name> config msiscsi start= auto

2Start the iSCSI service: sc start msiscsi

3Add a target portal:

iscsicli QAddTargetPortal

<IP_address_of_iSCSI_port_on_storage array>

If you are using Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, SUSE Linux Enterprise Server 10, or SUSE Linux Enterprise Server 11:

Configuration of the iSCSI initiator for Red Hat Enterprise Linux 5 and SUSE Linux Enterprise Server 10 SP1 distributions is done by modifying the /etc/iscsi/iscsid.conf file, which is installed by default when you install MDSM. You can edit the file directly, or replace the default file with a sample file included on the PowerVault MD series resource media.

To use the sample file included on the media:

1Save the default /etc/iscsi/iscsid.conf file by naming it to another name of your choice.

2Copy the appropriate sample file from /linux/etc on the media to /etc/iscsi/iscsid.conf.

3Rename the sample file to iscsid.conf.

4Edit the following entries in the /etc/iscsi/iscsid.conf file:

a Edit or verify that the node.startup = manual line is disabled. b Edit or verify that the node.startup = automatic line is

enabled. This enables automatic startup of the service at boot time.

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
