Automatically Resynchronizing Virtual Disks

When automatic resynchronization is selected, the RAID controller module owning the primary virtual disk automatically starts resynchronizing the data on the remote replication pair immediately after communication is restored.

NOTE: When choosing automatic resynchronization, a possible loss of data can occur if a resynchronization is interrupted in progress. Since another resynchronization begins automatically after communication is restored between the primary virtual disk and the remote virtual disk, data integrity could be affected.

With automatic resynchronization set, you cannot add a secondary virtual disk to a write consistency group. Therefore, write consistency during the resynchronization process is not preserved. The write order is not consistent until the entire group achieves Optimal status.

Manually Resynchronizing Virtual Disks

When manual resynchronization is selected, you must manually resynchronize and resume the data transfer on a remote replication after communication is restored between the primary and remote virtual disks. Manual resynchronization is the recommended setting for all remote replications for these reasons:

•You determine when resynchronization starts, which allows you to better manage and/or mitigate impact on I/O performance.

•In a disaster recovery situation, manual resynchronization offers the best chance of retrieving valid data.

•When the secondary virtual disk is in a write consistency group, manual resynchronization preserves the write order.

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.
