Reverting to Single Path Support from Redundant Path Support for PERC H810

If you need to revert to single path support from redundant path support, shut down the system and remove the exact same cables that were added to support redundant path support, leaving only one connection between the controller and enclosures. After you remove the cable and power up the system, ensure that there are no warning messages during boot, and that all virtual disks are online and optimal. If you are using Dell OpenManage, see the Dell OpenManage documentation at support.dell.com/manuals for additional instructions.

CAUTION: If you remove any cables other than the ones added to enable redundant path support, the enclosure and disks can get disconnected, and virtual disk may fail.

Perform the following steps to configure the hardware to utilize redundant paths on the PERC H810 card:

1Set up an enclosure on the PERC H810 card.

2Connect two SAS cables from the Out ports on your PERC H810 card to the In ports of the external enclosure. For more information, see Figure 3-4.

NOTE: For information on Unified Mode, see the enclosure documentation that was shipped with the enclosure.

3To add multiple enclosures, cable both Out ports of the first enclosure to both In ports of the next enclosure.

4After you set up the hardware, the controller detects the redundant paths and automatically utilizes them to balance the I/O load.

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.
