•Changing a host type

MDSM automatically detects these changes for any host running the host agent software.

Starting or Stopping the Host Context Agent

The host context agent discovers the host topology. The host context agent starts and stops with the host. The topology discovered by the host context agent can be viewed by clicking Configure Host Access (Automatic) in the Configure tab in the MDSM.

You must stop and restart the host context agent to see the changes to the host topology if:

•A new storage array is attached to the host server.

•A host is added while turning on power to the RAID controller modules.

Linux

To start or stop the host context agent, enter the following command at the prompt:

SMagent start

SMagent stop

You stop and then restart SMagent after:

•Moving a controller offline or replacing a controller.

•Removing host-to-array connections from or attaching host-to-array connections to a Linux host server.

Windows

To start or stop the host context agent:

1Click Start→ Settings→ Control Pane→ Administrative Tools→ Services. or

Click Start→ Administrative Tools→ Services.

2From the list of services, select Modular Disk Storage Manager Agent.

3If the host context agent is running, click Action→ Stop, then wait approximately 5 seconds.

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.
