Configuration: Premium Feature— Remote Replication

The Remote Replication premium feature enables real-time replication of data between two storage arrays in separate locations. Using remote replication, up to 16 replicated virtual disk pairs can be created on a storage array.

A replicated virtual disk pair is created from two standard virtual disks, both of which are logical data storage structures created on a storage array. A standard virtual disk can only be a member of one replicated pair. A pair consists of a primary virtual disk at a local storage array and a secondary virtual disk at a remote storage array. Data written by the host to the primary virtual disk is replicated directly from the primary storage array to the secondary virtual disk. No host server or application resources are used during replication. The data can be written either synchronously or asynchronously.

In the event of a disaster, loss of communications or catastrophic failure in the local storage array, the secondary virtual disk in the remote storage array can be promoted to the role of primary virtual disk and assume responsibility for maintaining business operations.

For detailed steps on creating virtual disks and implementing remote replication, see "Setting Up and Managing Remote Replication" on page 183.

Switchable Host Access Configuration Required With Remote Replication

Access to the host server from the local and/or remote storage arrays using remote replication must be established through a supported Fibre Channel switch configuration. Direct-attached configurations between the host server and Dell PowerVault MD storage arrays are not supported.

For more information on configuring the switch environment, see "Required Switch Zoning Configurations" on page 182.

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.
