Dirty Cache Data Error Message

Error Message: The cache contains dirty data, but some virtual disks are missing or will go offline, so the cached data can not be written to disk. If this is an unexpected error, then please power off your system and check your cables to ensure all disks are present. If you continue, the data in cache will be permanently discarded. Press 'X' to acknowledge and permanently destroy the cached data.

Probable Cause: The controller preserves the dirty cache from a virtual disk if the disk becomes offline or is deleted because of missing physical disks. This message indicates that some configured disks were removed. If the disks were not removed, they are no longer accessible. The SAS cables for your system might be improperly connected.

Corrective Action: Check the cable connections and fix any problems. Restart the system. Use the <Ctrl><R> utility to import the virtual disk or discard the preserved cache. For the steps to manage preserved cache, see "Managing Preserved Cache" on page 68.

BIOS Disabled Error Message

Error Message: BIOS Disabled. No Logical Drives Handled by

BIOS

Probable Cause: This warning message is displayed after you disable the ROM option in the configuration utility. When the ROM option is disabled, the BIOS cannot boot to INT 13h and cannot provide the ability to boot from the virtual disk. Int 13h is an interrupt signal that supports numerous commands that are sent to the BIOS, then passed to the physical disk. The commands include actions you can perform with a physical disk, such as reading, writing, and formatting.

Corrective Action: Enable the ROM option.

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.
