Deleting Virtual Disks

NOTE: You cannot delete a virtual disk during an initialization.

NOTE: Warning messages appear stating the effect of deleting a virtual disk. Click OK twice to complete the virtual disk deletion.

To delete virtual disks, perform the following steps in the BIOS Configuration Utility (<Ctrl><R>):

1Press <Ctrl><N> to access the VD Mgmt screen.

2Use the arrow keys to move the cursor to the Virtual Disks heading.

3Press <F2>.

The action menu is displayed.

4Select Delete VD and press <Enter>.

5If there are multiple virtual disks in a Disk Group, select Total Free Capacity for the Disk Group in the VD Mgmt screen.

The total amount of free space available in the Disk Group is displayed.

Deleting Disk Groups

You can delete disk groups using the BIOS Configuration Utility (<Ctrl><R>). When you delete a disk group, the utility also removes the virtual disks in that disk group.

To delete disk groups, perform the following steps in the BIOS Configuration Utility (<Ctrl><R>):

1Press <Ctrl><N> to access the VD Mgmt screen.

2Use the arrow keys to move the cursor to the Virtual Disks heading.

3Press <F2>.

The action menu is displayed.

4Select Delete Disk Group and press <Enter>. The disk group is deleted.

When you delete a disk group, the remaining disk groups with higher numbers are automatically renumbered. For example, if you delete disk group #2, then disk group #3 is automatically renumbered as disk group #2.

H310, H710, H710P, H810 specifications

Dell offers a range of storage controller technologies, notably the H810, H710, H710P, and H310, which cater to different enterprise needs. These controllers are designed to support various storage configurations, enhancing overall system performance and reliability.

The Dell H810 is a high-performance PCIe 3.0 RAID controller that supports up to eight internal drives and is particularly suited for demanding workloads. It features advanced RAID levels including RAID 0, 1, 5, 6, 10, 50, and 60, providing flexibility for various data protection strategies. The H810 also supports up to 32TB of storage capacity, making it suitable for environments that require substantial data management capabilities.

The H710 is another powerful RAID controller, widely recognized for its balance of performance and cost-efficiency. It features 1GB of cache memory, which aids in accelerating read and write operations. The H710 supports the same RAID levels as the H810 and allows for up to 512MB of non-volatile memory. This ensures data integrity even in the event of a power failure, making it reliable for critical applications.

The H710P is an enhanced version of the H710, with a significant upgrade in its cache capabilities. It offers 2GB of battery-backed cache memory, further enhancing data processing speeds and improving responsiveness. The H710P is ideal for intensive workloads and virtualization, where rapid access to data is essential. This controller also includes features such as RAID storage pooling, intelligent data tiering, and support for multiple virtual disks.

Finally, the H310 is a cost-effective option for small to medium-sized businesses or those with less demanding storage requirements. It offers similar RAID support as the higher-end controllers but operates with a simpler architecture. The H310 features 512MB of cache, providing sufficient performance for regular workloads without the additional complexities of more advanced controllers.

In summary, Dell's H810, H710, H710P, and H310 storage controllers each serve distinct purposes, providing various features, technologies, and performance characteristics tailored to different business needs. From high-capacity storage solutions to user-friendly setups, Dell’s offerings ensure that organizations can efficiently manage their data storage requirements.
