Introduction to Storage Arrays

•Display resolution of 1024x768 with 16 million colors (1280x1024 32-bit recommended)

•Microsoft Windows, Red Hat Enterprise Linux, or SUSE Linux Enterprise Server.

NOTE: Operating system installations can be either native or hypervisior guest configurations.

NOTE: Supported hypervisors include Microsoft Hyper-V, Citrix XenServer, and VMware. For information about the supported versions, see the Support Matrix at support.dell.com/manuals.

•Administrator or equivalent permissions.

An enclosure containing physical disks accessed through RAID controller modules is called a storage array. A storage array includes various hardware components, such as physical disks, RAID controller modules, fans, and power supplies, gathered into enclosures.

One or more host servers attached to the storage array can access the data on the storage array. You can also establish multiple physical paths between the host(s) and the storage array so that loss of any single path (for example, through failure of a host server port) does not result in loss of access to data on the storage array.

The storage array is managed by MDSM running on a:

•Host server—On a host server system, MDSM and the storage array communicate management requests and event information using SAS connections.

•Management station—On a management station, MDSM communicates with the storage array either through an Ethernet connection to the storage array management port or through an Ethernet connection to a host server. The Ethernet connection passes management information between the management station and the storage array using SAS connections.

Using MDSM, you can configure the physical disks in the storage array into logical components called disk groups and then divide the disk groups into virtual disks. Disk groups are created in the unconfigured capacity of a storage array. Virtual disks are created in the free capacity of a disk group.

Introduction

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.
