Configuring Target CHAP Authentication on the Storage Array

1From MDSM, click the iSCSI tab and then click Change Target Authentication.

Select one of the CHAP settings described in Table A-4.

Table A-4. CHAP Setting

Option

Description

 

 

None

This is the default selection. If None is the only selection, the

 

storage array allows an iSCSI initiator to log on without

 

supplying any type of CHAP authentication.

None and CHAP The storage array allows an iSCSI initiator to log on with or

 

without CHAP authentication.

CHAP

If CHAP is selected and None is deselected, the storage array

 

requires CHAP authentication before allowing access.

 

 

2To configure a CHAP secret, select CHAP and select CHAP Secret.

3Enter the Target CHAP Secret (or Generate Random Secret). Confirm it in Confirm Target CHAP Secret and click OK.

Although the storage array allows sizes from 12 to 57 characters, many initiators only support CHAP secret sizes up to 16 characters (128-bit).

NOTE: A CHAP secret is not retrievable after it is entered. Ensure that you record the secret in an accessible place. If Generate Random Secret is used, copy and paste the secret into a text file for future reference since the same CHAP secret is used to authenticate any new host servers you may add to the storage array. If you forget this CHAP secret, you must disconnect all existing hosts attached to the storage array and repeat the steps in this chapter to re-add them.

4Click OK.

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.
