Dell Perc H800 SAS Raid Controller With 512MB Cache NCHRW

Cache Feature

The Dell Perc H800 PCI-Express SAS Raid Controller comes equipped with an impressive cache feature that includes a 512MB cache. This cache is a vital component of the controller and plays a crucial role in enhancing the overall performance and efficiency of your storage system.

Improved Data Transfer Speeds

One of the primary benefits of having a cache feature with a generous capacity like 512MB is the significant improvement in data transfer speeds. The cache acts as a buffer between the server and the storage devices, temporarily storing frequently accessed data. This allows for faster retrieval of data, reducing latency and ensuring that your system operates smoothly even during peak usage periods.

Enhanced Performance in Read-Intensive Workloads

The cache feature in the Dell Perc H800 also proves to be particularly advantageous in read-intensive workloads. Since frequently accessed data is stored in the cache, subsequent read requests can be fulfilled directly from the cache instead of having to retrieve the data from the underlying storage devices. This results in reduced latency and improved response times, enhancing the overall performance of your system.

Accelerated Write Operations

While the cache is primarily known for its impact on read operations, it also plays a significant role in write operations. The Dell Perc H800 utilizes a write-back caching mechanism where write requests are initially stored in the cache before being written to the disk. This approach allows for faster write speeds since the system can acknowledge the completion of a write operation as soon as it is stored in the cache. Subsequently, the data can be written to the underlying storage devices at an optimized time, reducing any potential bottlenecks.

Data Protection and Redundancy

In addition to its performance benefits, the cache feature also contributes to data protection and redundancy. The Dell Perc H800 implements a battery-backed cache module, ensuring that any data stored in the cache is protected in the event of power loss. This helps prevent data loss or corruption and provides an added layer of security for your critical data.

Increased Scalability

The 512MB cache capacity of the Dell Perc H800 enables improved scalability for your storage system. As your data storage requirements grow, the cache allows for efficient handling of increasing workloads and supports a larger number of concurrent users. This scalability ensures that your system can handle expanding data volumes without compromising on performance or responsiveness.

Part Number Feature

The Dell Perc H800 PCI-Express SAS Raid Controller is identified by its unique part number, which in this case is NCHRW. This part number holds significance for users as it provides important information and helps in identifying and differentiating the specific variant of the controller.

Easy Identification and Compatibility

The part number, NCHRW, serves as a unique identifier for the Dell Perc H800 controller. When purchasing or searching for information about this particular model, the part number allows you to easily identify and ensure compatibility with your system. This eliminates any confusion or potential compatibility issues that may arise when selecting a RAID controller for your storage infrastructure.

Support and Documentation

Having a specific part number like NCHRW facilitates access to dedicated support and documentation resources from Dell. Whether you require technical assistance or seek detailed information about the controller's features and capabilities, the part number ensures that you can access the right resources specifically tailored to your model. This makes troubleshooting, maintenance, and upgrades much more efficient and streamlined.

Warranty and Service Coverage

The part number plays an essential role in determining warranty coverage and service options for your Dell Perc H800 controller. By providing the part number, you can easily validate warranty entitlements and ensure that your controller is eligible for any necessary repairs or replacements. This simplifies the process of obtaining support and ensures that you can maximize the longevity and performance of your storage solution.

In conclusion, the Dell Perc H800 PCI-Express SAS Raid Controller's cache feature, with its 512MB capacity, offers numerous benefits to users. It enhances data transfer speeds, improves performance in read-intensive workloads, accelerates write operations, provides data protection and redundancy, and allows for increased scalability. The part number feature, specifically NCHRW, facilitates easy identification, compatibility, access to support and documentation, and warranty coverage for users of this RAID controller. These features combine to make the Dell Perc H800 a powerful and reliable choice for optimizing storage performance and efficiency in various computing environments.
