Journaling File Systems and Remote Replication

When using a journaling file system, you cannot gain read-only access to a remote virtual disk. A journaling file system does not let you mount the remote virtual disk in Windows NTFS. However, you can mount a snapshot of the remote virtual disk, if available.

Setting Up and Managing Remote Replication

Prerequisites

Before setting up remote replication between two storage arrays, ensure that:

•The Remote Replication premium feature has been activated.

•The local storage array contains two replication repository virtual disks (created during activation).

•The local storage array contains the primary virtual disk to be replicated.

•The remote storage array contains the secondary virtual disk to serve as the replication target, and:

–Both virtual disks are visible to a single management station; replicated disk pairs cannot be managed on separate instances of storage management software.

–The RAID level of the secondary virtual disk can be different than that of the primary virtual disk.

–The capacity of the secondary virtual disk (after creation and formatting) must be equal to or greater than the capacity of the primary virtual disk.

•The storage arrays containing the virtual disks you want to replicate are connected to each other through a Fibre Channel switch fabric and are accessible from a single management station.

If either the primary or secondary virtual disk does not exist, you must create it before proceeding with remote replication setup. See "Activating the Remote Replication Premium Feature and Creating Replication Virtual Disks" on page 184 and complete the necessary steps.

If all virtual disks are created, skip to "Creating a Remote Replication" on page 186.

MD3600f, MD3620F 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.
