Physical Disk Actions

Table 5-6 describes the actions you can perform on physical disks.

For procedures that can be used to perform the actions, see "Physical Disk Management" on page 81.

Table 5-6. Physical Disk Actions

Action

Description

 

 

Rebuild

Regenerates all data to a replacement disk in a redundant

 

virtual disk (RAID level 1, 5, 6, 10, 50, or 60) after a disk

 

failure. A disk rebuild normally occurs without interrupting

 

normal operations on the affected virtual disk.

 

 

Replace Member

Replaces the disk in the virtual disk with another disk that can

 

be selected.

 

 

LED Blinking

Indicates when physical disks are being used to create a virtual

 

disk. You can choose to start or stop the LED blinking.

 

 

Force Online

Changes the state of the selected physical disk to online.

 

 

Force Offline

Changes the state of the selected physical disk so that it is no

 

longer part of a virtual disk.

 

 

Make Global HS

Designates the selected physical disk as a global hot spare.

 

A global hot spare is part of a pool for all virtual disks

 

controlled by the controller.

 

Designates the selected physical disk as a global hot spare.

 

 

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 "Performing a Manual Rebuild of an Individual Physical Disk" on page 85.

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 support.dell.com/manuals.

Dell H710P, H310, H810 manual Rebuild, Physical Disk Actions Description

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.
