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 might occur when a new battery is charging, when a RAID controller module has been removed, or if a mismatch in cache sizes has been detected by the RAID controller module. After the condition has 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 appear 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.

To change the virtual disk cache settings:

1In the AMW, select the Logical tab and select a virtual disk

2In the toolbar, select Virtual Disk→ Change→ Cache Settings.

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
