There are four power saving modes available:

•No Power Savings (default mode)—All power savings features are disabled.

•Balanced Power Savings—Spin down is enabled only for unconfigured and hot spare disks.

•Maximum Power Savings—Spin down is enabled for configured, unconfigured and hot spare disks.

•Customized Power Savings—All power savings features are customizable. You can specify a Quality of Service window during which the configured disks are excluded from spin-down.

Configured Spin Down Delay

NOTE: The Configured Spin Down Delay option is not applicable for the No Power

Savings mode.

The amount of time to wait before spinning down disks can be set using Configured Spin Down Delay. The minimum value of the timer is 30 minutes (default) and the maximum is 1 day. Disks are spun down automatically and spun up when accessed. All disks are spun up on reboot.

NOTE: There is a delay to I/O operations when a configured disk is being spun up.

Types of Virtual Disk Initialization

You can initialize the virtual disks as described in the following sections.

CAUTION: The initializing virtual disks task erases the files and file systems while keeping the virtual disk configuration intact. Initializing a virtual disk destroys all data on the virtual disk.

NOTE: The initialization operations mentioned here are not applicable for Non-RAID disks.

Background Initialization of Virtual Disks

Background Initialization (BGI) is an automated process that writes the parity or mirror data on newly created virtual disks. BGI does not run on RAID 0 virtual disks.You can control the BGI rate in the Dell OpenManage storage management application. Any change in the BGI rate does not take effect until the next BGI run.

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.
