•The controller discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed.

•The battery may be under charged.

Corrective Action: Allow the battery to charge fully to resolve this problem. If the problem persists, the battery or adapter DIMM might be faulty. Contact Dell Technical Support.

Firmware Fault State Error Message

Error Message: Firmware is in Fault State

Corrective Action: Contact Dell Technical Support.

Foreign Configuration Found Error Message

Error Message: Foreign configuration(s) found on adapter. Press any key to continue, or ’C’ to load the configuration utility or ’F’ to import foreign configuration(s) and continue.

Probable Cause: When a controller firmware detects a physical disk with existing foreign metadata, it flags the physical disk as foreign and generates an alert indicating that a foreign disk was detected.

Corrective Action: Press <F> at this prompt to import the configuration (if all member disks of the virtual disk are present) without loading the BIOS Configuration Utility (<Ctrl><R>). Or, press <C> to enter the BIOS Configuration Utility (<Ctrl><R>) and either import or clear the foreign configuration.

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.
