Break Mirror in BIOS Configuration Utility

To use the Break Mirror feature from the BIOS Configuration Utility (<Ctrl><R>), perform the following steps:

The RAID1 VD that you are to split must be in an optimal state, and it cannot be running any other background tasks.

1During boot up, press <Ctrl><R> when prompted by the BIOS screen. If there is more than one controller in the system, choose the controller. The VD Mgmt screen is displayed by default.

2On the VD Mgmt screen, highlight the appropriate Disk Group.

3Press <F2> to display the available actions.

4Choose Break Mirror and press <Enter>.

A dialog is displayed describing the operation and asking if you are sure you want to perform the operation.

5Select Yes to continue.

The exported disk (exporting configuration) spins down and the hard drive status LED starts flashing to identify which drive must be pulled.

The remaining disk (exporting configuration) is in a degraded state until the missing member is replaced or rebuilt.

If there are any Global or Dedicated Hot Spare assigned which fulfills the rebuild requirements for the degraded RAID1 disk, a rebuild starts automatically. If there is no Hot Spare assigned, then a Hot Spare that meets all the requirements for the VD must be assigned before the rebuild starts.

NOTE: Importing a Broken Mirror is the same as importing a Foreign configuration. See "Importing or Clearing Foreign Configurations Using the VD Mgmt Menu" on page 63 of this document. The imported VD is be in a degraded state until the missing member is rebuilt.

Dell H810, H710P, H310 manual Break Mirror in Bios Configuration Utility

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.
