1In the AMW, select the Logical tab.

2Select a virtual disk.

3In the toolbar, select Virtual Disk→ Change→ Modification Priority. The Change Modification Priority window is displayed.

4Select one or more virtual disks.

To select nonadjacent virtual disks, press <Ctrl> click. To select adjacent virtual disks, press <Shift> click. To select all of the available virtual disks, click Select All. Move the Select modification priority slider bar to the desired priority.

5Click OK.

A message prompts you to confirm the change in the virtual disk modification priority.

6Click Yes.

7Click OK.

Changing the Virtual Disk Cache Settings

You can specify the cache memory settings for a single virtual disk or for multiple virtual disks on a storage array.

Guidelines to change cache settings for a virtual disk:

•After opening the Change Cache Settings dialog, the system may prompt you that the RAID controller module has temporarily suspended caching operations. This action may occur when a new battery is charging, when a RAID controller module is removed, or if a mismatch in cache sizes is detected by the RAID controller module. After the condition is cleared, the cache properties selected in the dialog become active. If the selected cache properties do not become active, contact your Technical Support representative.

•If you select more than one virtual disk, the cache settings default to no settings selected. The current cache settings are displayed only if you select a single virtual disk.

•If you change the cache settings by using this option, the priority of all of the virtual disks that you selected is modified.

107 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.
