ParameterDescription

No-Read-Aheadspecifies that the controller does not use read ahead for the current virtual disk.

Adaptive specifies that the controller begins using Read-Aheadif the two most recent disk accesses occurred in sequential sectors. If all read requests are random, the algorithm reverts to No-Read-Ahead; however, all requests are still evaluated for possible sequential operation.

Virtual Disk Management

Creating Virtual Disks

NOTE: Combining SAS and SATA disk drives within a virtual disk is not supported. Also, combining disk drives and SSDs within a virtual disk is not supported.

NOTE: To create secured virtual disks, see the topic Security Key And RAID Management.

Perform the following steps to create a virtual disk:

1.During host system bootup, press <Ctrl><R> after the BIOS screen is displayed.

The Virtual Disk Management screen is displayed. If there is more than one controller, the main menu screen is displayed. Select a controller, and press <Enter>. The Virtual Disk Management screen is displayed for the selected controller.

2.Use the arrow keys to highlight Controller # or Disk Group #.

3.Press <F2>.

The list of available actions is displayed.

4.Select Create New VD and press <Enter>.

The Create New VD screen is displayed. The cursor is on the RAID Levels option. When adding a virtual disk to a Disk Group, the Add VD in Disk Group screen is displayed. Skip to step 11 to change the basic settings of the virtual disk.

5.Press <Enter> to display the possible RAID levels, based on the physical disks available.

6.Press the down-arrow key to select a RAID level and press <Enter>.

7.When creating a spanned virtual disk (RAID 10, 50 or 60), enter the number of physical disks per span in the PD per Span field and press <Enter>.

NOTE: Creating a 22 physical disk RAID 10 VD is possible by selecting RAID 10 and populating the PD per Span field with 22.

8.Press <Tab> to move the cursor to the list of physical disks.

9.Use the arrow key to highlight a physical disk and press the spacebar, <Alt> , or <Enter> to select the disk.

10.Select additional disks, if required.

NOTE: (PERC H310) Only RAID Capable physical disks are eligible to be included in a Virtual Disk. To convert physical disks to RAID Capable, see the topic Converting Physical Disk To RAID Capable For PERC H310.

11.Press <Tab> to move the cursor to the Basic Settings box.

12.Set the virtual disk size in the VD Size field. The virtual disk size is displayed in GB format.

13.Press <Tab> to access the VD Name field, and type a virtual disk name.

14.Press <Tab> to move the cursor to Advanced Settings.

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.
