A disk group should be organized according to its related tasks and subtasks. For example, if you create a disk group for the Accounting Department, you can create virtual disks that match the different types of accounting performed in the department: Accounts Receivable (AR), Accounts Payable (AP), internal billing, and so forth. In this scenario, the AR and AP virtual disks probably need more capacity than the internal billing virtual disk.

NOTE: In Linux, the host must be rebooted after deleting virtual disks to reset the /dev entries.

NOTE: Before you can use a virtual disk, you must register the disk with the host systems. See "Host-to-Virtual Disk Mapping" on page 124.

Creating Disk Groups

You can create disk groups using either Automatic configuration or Manual configuration.

To create disk groups using automatic configuration:

1To start the Create Disk Group Wizard, perform one of these actions:

•To create a disk group from unconfigured capacity in the storage array—On the Logical tab, select an Unconfigured Capacity node, and select Disk Group→ Create. Alternatively, you can right-click the Unconfigured Capacity node, and select Create Disk Group from the pop-up menu.

•To create a disk group from unassigned physical disks in the storage array—On the Physical tab, select one or more unassigned physical disks of the same physical disk type, and select Disk Group→ Create. Alternatively, you can right-click the unassigned physical disks, and select Create Disk Group from the pop-up menu.

•To create a secure disk group—On the Physical tab, select one or more unassigned security capable physical disks of the same physical disk type, and select Disk Group→ Create. Alternatively, you can right- click the unassigned security capable physical disks, and select Create Disk Group from the pop-up menu.

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.
