Dell PERC H700 6GBPS SAS-SATA RAID Controller J1FW8

Cache Feature: 512MB

Enhanced Performance and Data Protection

The Dell PERC H700 RAID Controller is equipped with an impressive 512MB cache feature, which plays a crucial role in enhancing the overall performance and data protection capabilities of the controller. With a large cache, this RAID controller can efficiently handle and process data, resulting in faster and more reliable operations.

Accelerated Read and Write Operations

One of the key benefits of the 512MB cache feature is its ability to accelerate both read and write operations. When a user requests data from the storage drives, the controller can store frequently accessed information in its cache memory. This allows for quicker retrieval of data, significantly reducing latency and improving overall system performance.

Similarly, when data needs to be written to the storage drives, the controller can temporarily store it in the cache before committing it to the disks. This write caching capability eliminates the need for immediate disk access, resulting in faster write speeds. The larger the cache, the more data can be stored temporarily, enabling smooth and efficient operations even during peak usage periods.

Improved I/O Performance

The 512MB cache feature also contributes to improved I/O (Input/Output) performance. As data is processed and stored in the cache, it reduces the number of I/O requests that need to be sent to the storage drives. This reduction in I/O requests minimizes latency and improves overall system responsiveness.

Furthermore, the cache feature optimizes I/O operations by intelligently managing data placement. It can prioritize frequently accessed data to be stored in the cache, ensuring that critical information is readily available for quick retrieval. This intelligent data management results in faster I/O response times and enhances overall system efficiency.

Data Protection and Redundancy

In addition to performance enhancements, the 512MB cache feature provides crucial data protection and redundancy capabilities. In the event of a sudden power loss or system failure, the cache memory acts as a temporary backup for data that has not yet been committed to the disks.

With the help of battery backup units (BBUs), the cache can retain the data even during power outages. This ensures that no data is lost or corrupted, maintaining data integrity and preventing potential disruptions. Once the power is restored, the controller flushes the cached data to the disks, ensuring that all information is safely written and protected.

Flexibility and Customization

The Dell PERC H700 RAID Controller allows users to customize and configure the cache feature according to their specific requirements. Through the management software provided by Dell, users can adjust cache size, policies, and settings to optimize performance and data protection based on their unique workload demands.

Cache Policies

The cache feature offers different policies that can be tailored to suit specific application needs. These policies include "Write-Through" and "Write-Back."

- Write-Through: With this policy, any data written to the controller is immediately written to both the cache and the disks simultaneously. While this ensures data integrity, write speeds may be slightly slower compared to other policies.

- Write-Back: In this policy, data is initially written only to the cache, resulting in faster write speeds. The controller then periodically flushes the cached data to the disks. However, there is a slight risk of data loss if a power failure occurs before the data is flushed.

By allowing users to choose between these policies, the controller offers flexibility in balancing performance and data protection based on individual preferences.

Battery Backup Units (BBUs)

To ensure uninterrupted operation and data protection, it is recommended to utilize battery backup units (BBUs) with the Dell PERC H700 RAID Controller. BBUs provide backup power to the cache memory in case of power failures, allowing the controller to flush the cached data to the disks safely.

By investing in BBUs, users can significantly reduce the risk of data loss or corruption during unforeseen events. This additional layer of protection ensures that critical data remains intact and available, even in challenging circumstances.

Interface Feature: 6GBPS SAS-SATA

High-Speed Data Transfer

The Dell PERC H700 RAID Controller boasts an advanced 6GBPS SAS-SATA interface, which offers high-speed data transfer capabilities. This interface enables seamless communication between the controller and the storage drives, ensuring rapid access to data and efficient data transmission.

Compatibility and Scalability

The 6GBPS SAS-SATA interface provides compatibility with a wide range of SAS and SATA drives, offering flexibility and scalability for various storage configurations. Whether users require high-performance SAS drives or cost-effective SATA drives, this interface can accommodate diverse storage needs without compromising on speed or reliability.

Furthermore, the interface supports both SAS and SATA protocols simultaneously, enabling mixed drive configurations within the same RAID array. This versatility allows users to maximize their storage capacity while maintaining optimal performance.

Increased Bandwidth

With a 6GBPS data transfer rate, the interface significantly increases the available bandwidth compared to older generation interfaces. This enhanced bandwidth allows for faster and more efficient transfer of large files, reducing file transfer times and improving overall system responsiveness.

Whether it's transferring multimedia files, running resource-intensive applications, or conducting data-intensive tasks, the high-speed interface ensures that users can seamlessly access and manipulate their data without experiencing any bottlenecks.

Future-Proofing

Investing in a RAID controller with a 6GBPS SAS-SATA interface ensures future-proofing for upcoming storage technologies and advancements. As storage technologies continue to evolve, higher-speed drives and improved protocols are being introduced. By having a controller with a 6GBPS interface, users can take advantage of these advancements without the need for immediate hardware upgrades.

This future-proofing capability not only saves costs in the long run but also ensures that users can leverage the latest storage technologies without any compatibility issues or performance limitations.

Seamless Integration

The 6GBPS SAS-SATA interface seamlessly integrates with existing IT infrastructures. Whether it's a new installation or an upgrade to an existing system, the interface allows for easy integration without requiring significant changes or disruptions to the overall setup.

This seamless integration ensures a smooth transition, allowing users to quickly benefit from the increased performance and reliability offered by the Dell PERC H700 RAID Controller without extensive configuration or reorganization of their storage environment.

Hot-Swap Support

The 6GBPS SAS-SATA interface supports hot-swapping, allowing for easy replacement or addition of drives without shutting down the system. This hot-swap capability minimizes downtime and ensures uninterrupted operation, making maintenance tasks more efficient and convenient.

By simply plugging in new drives or removing faulty ones while the system is running, users can quickly expand their storage capacity or replace malfunctioning drives without impacting ongoing operations. This feature is particularly valuable in environments where continuous uptime is crucial, such as data centers or enterprise server rooms.

In conclusion, the Dell PERC H700 RAID Controller's cache feature with its substantial 512MB capacity delivers enhanced performance, data protection, and flexibility to users. Moreover, the 6GBPS SAS-SATA interface offers high-speed data transfer, compatibility with various drives, increased bandwidth, future-proofing capabilities, seamless integration, and hot-swap support. With these features, the Dell PERC H700 RAID Controller empowers users with a reliable and efficient storage solution that meets their performance and data protection requirements.
