As part of Dell's PERC (PowerEdge RAID Controller) family, the H840 offers advanced features that ensure seamless data handling, minimal downtime, and optimal storage performance. In this section, we will delve deeper into the functionality, features, and benefits of this particular model, providing insights into its capabilities and use cases in enterprise-level environments.

Key Features

Advanced PCI-E 3.1 Interface

One of the standout features of the Dell PERC H840 RAID Controller is its PCI-E 3.1 interface. This interface offers data transfer speeds of up to 8 lanes, ensuring high bandwidth and low latency. With PCI-E 3.1, the controller delivers up to 32GBps throughput, making it an ideal choice for systems requiring high-performance data handling.

SAS-12GBPS Support

The PERC H840 supports SAS-12GBPS, which provides faster data throughput between the RAID controller and storage devices. This SAS standard ensures quick and efficient data access, even under heavy loads, making the H840 perfect for demanding storage applications such as virtualization, databases, and high-performance computing environments.

4GB NV Cache for Improved Performance

The inclusion of a 4GB Non-Volatile (NV) cache is another key feature of the 19D8P model. This cache significantly enhances performance by providing faster data access and read/write operations. In case of power loss, the NV cache preserves data integrity, making it a reliable solution for critical business applications that cannot afford data loss.

Benefits

Data Protection and Integrity

Data protection is a top priority for businesses dealing with sensitive or mission-critical data. The Dell PERC H840 RAID controller ensures data integrity through advanced RAID features. It supports a variety of RAID levels, such as RAID 0, 1, 5, 10, 50, and 60, allowing administrators to choose the best configuration based on their storage requirements. This flexibility ensures that data can be stored securely with redundancy, minimizing the risk of data loss due to hardware failure.

High Availability and Reliability

For businesses, downtime can result in significant operational disruptions and revenue loss. The PERC H840 RAID controller is designed for high availability and reliability, minimizing the risk of system failures. With features such as battery-backed cache, automatic rebuild, and hot spare support, the H840 ensures that your storage environment remains operational and resilient against failures.

Scalability for Growing Data Needs

As data storage needs continue to grow, businesses must invest in scalable solutions. The Dell PERC H840 is highly scalable, supporting up to 240 physical devices when paired with external storage enclosures. This scalability makes the H840 an excellent option for data centers and enterprises that anticipate rapid growth or require flexible storage solutions to meet evolving demands.
