After the remote virtual disk replication resumes, data is automatically written to the secondary virtual disk. Only the regions of the primary virtual disk that changed since the replicated pair was suspended are written to the secondary virtual disk.

CAUTION: Possible loss of data access: When you resume a remote virtual disk replication involving a primary or secondary virtual disk that is a member of a write consistency group, any other suspended remote replications for replicated pairs in the write consistency group also resumes.

NOTE: If the write mode is synchronous, you do not need to resynchronize the primary and secondary virtual disk after resuming a remote virtual disk replication.

Testing Communication Between the Primary and Secondary Virtual Disks

When a resynchronization is manual or during a disaster recovery scenario, you may want to test the communication between the primary virtual disk and secondary virtual disk in a remote replication. For more information about synchronization and resynchronization in remote virtual disk replications, go to these topics:

•"Normally Synchronized Virtual Disks" on page 204.

•"Unsynchronized Virtual Disks" on page 207.

•"Setting Synchronization Priority and Synchronization Method" on page 196.

•"Changing Synchronization Priority and Method" on page 205.

•"Resynchronizing Virtual Disks" on page 204.

•"Automatically Resynchronizing Virtual Disks" on page 208.

To test the communication between virtual disks in a remote replication:

1In the AMW of either the primary or secondary virtual disk, select the Logical tab.

2In the Logical pane, right-click the virtual disk.

3Select Test Replication Communication.

The Replication Communication Test Progress message is displayed.

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.
