Host Topology

Host topology is the organization of hosts, host groups, and host interfaces configured for a storage array. You can view the host topology in the Mappings tab of the AMW. For more information, see "Using the Mappings Tab" on page 90.

The following tasks change the host topology:

•Moving a host or a host connection

•Renaming a host group, a host, or a host connection

•Adding a host connection

•Replacing a host connection

•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 and 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.

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
