Automatic Replace Member with Predicted Failure

A Replace Member operation can occur when there is a SMART predictive failure reporting on a physical disk in a virtual disk. The automatic Replace Member is initiated when the first SMART error occurs on a physical disk that is part of a virtual disk. The target disk needs to be a hot spare that qualifies as a rebuild disk. The physical disk with the SMART error is marked as failed only after the successful completion of the Replace Member. This avoids putting the array in degraded status.

If an automatic Replace Member occurs using a source disk that was originally a hot spare (that was used in a rebuild), and a new disk added for the Replace Member operation as the target disk, the hot spare reverts to the hot spare state after a successful Replace Member operation.

NOTE: To enable the automatic Replace Member, use the Dell OpenManage storage management application. For more information on automatic Replace Member, see "Dell OpenManage Storage Management" on page 51. For information on manual Replace Member, see "Replacing an Online Physical Disk" on page 83.

Patrol Read

The Patrol Read feature is designed as a preventative measure to ensure physical disk health and data integrity. Patrol Read scans for and resolves potential problems on configured physical disks. The Dell OpenManage storage management application can be used to start Patrol Read and change its behavior.

The following is an overview of Patrol Read behavior:

•Patrol Read runs on all disks on the controller that are configured as part of a virtual disk, including hot spares.

•Patrol Read does not run on physical disks that are not part of a virtual disk or are in Ready state.

•Patrol Read adjusts the amount of controller resources dedicated to Patrol Read operations based on outstanding disk I/O. For example, if the system is busy processing I/O operation, then Patrol Read uses fewer resources to allow the I/O to take a higher priority.

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.
