Description

 

 

Remove HS

Removes a dedicated hot spare from its disk group or a global hot spare from the global

 

pool of hot spares.

Rebuild

Select Rebuild to rebuild one or more failed physical disks. For information on performing a physical disk rebuild, see the topic Performing A Manual Rebuild Of An Individual Physical Disk.

Several of the controller configuration settings and the virtual disk settings affect the actual rate of rebuild. The factors include the rebuild rate setting, virtual disk stripe size, virtual disk read policy, virtual disk write policy, and the amount of workload placed on the storage subsystem. For information on getting the best rebuild performance from your RAID controller, see the documentation at dell.com/support/manuals.

The listed rates in the following table were taken during single disk failure with no I/O present on a PERC H810 card connected to a single PowerVault MD1220 enclosure. Rates vary depending on type, speed and number of hard drives present in array; as well as which controller model and enclosure configuration are being used.

Controller Management (Ctrl Mgmt)

The Controller Management screen (Ctrl Mgmt) displays the product name, package, firmware version, BIOS version, boot block version, controller ID, security capability, and security key presence. Use the screen to perform actions on the controller and BIOS. You can perform functions such as enable or disable the controller BIOS, enable or disable the BIOS during bootup in the event of BIOS errors, and enable or disable the option to Auto Import. In addition, you can select a virtual disk from which to boot, and select default settings.

Enable Controller BIOS

Select the option to enable the controller BIOS. If the boot

 

device is on the RAID controller, the BIOS must be

 

enabled.

 

Disable the BIOS to use other boot devices.

 

In a multiple controller environment, you can enable BIOS

 

on multiple controllers. However, if you want to boot from

 

a specific controller, then enable the BIOS on that

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.
