Dell 405-AAYY PERC H755 RAID Controller Card with 8GB NV Cache

Cache Feature: 8GB NV

The Dell PERC H755 RAID Controller Card is equipped with an impressive cache feature, boasting an 8GB NV (Non-Volatile) cache. This cache acts as a temporary storage space for frequently accessed data, significantly improving the performance and efficiency of the RAID controller. Let's delve deeper into the benefits and importance of this cache feature.

Enhanced Read and Write Performance

The 8GB NV cache in the Dell PERC H755 RAID Controller Card plays a crucial role in enhancing both read and write performance. With a larger cache size, more data can be stored temporarily, reducing the need to access the physical drives frequently. As a result, read and write operations are accelerated, leading to faster data transfers and improved overall system performance.

Reduced Latency

Latency, or the delay between requesting and receiving data, can be a major bottleneck in any storage system. The 8GB NV cache helps minimize this latency by storing frequently accessed data closer to the RAID controller. As a result, data retrieval becomes faster, reducing the time it takes for applications to access critical information.

Improved I/O Efficiency

The Dell PERC H755 RAID Controller Card's cache feature also enhances I/O (Input/Output) efficiency. By temporarily storing frequently accessed data in the cache, the number of I/O operations required to retrieve data from the physical drives is significantly reduced. This reduces the strain on the drives and improves their overall lifespan.

Data Protection

In addition to boosting performance, the 8GB NV cache also plays a vital role in data protection. In the event of a power outage or system failure, the Non-Volatile nature of the cache ensures that the cached data remains intact. This means that even if power is lost, critical data stored in the cache is not lost, reducing the risk of data corruption or loss.

Increased Scalability

Another significant advantage of the 8GB NV cache is its contribution to increased scalability. The larger cache size allows for more efficient handling of large datasets and workloads. This is particularly beneficial for businesses that deal with massive amounts of data and require quick and reliable access to that data.

Features: Supports RAID levels 0, 1, 5, 6, 10, 50, and 60

The Dell PERC H755 RAID Controller Card is packed with an array of powerful features that make it an ideal choice for various storage environments. One of its standout features is the support for multiple RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. Let's explore the benefits and importance of these features.

RAID Level Flexibility

The support for multiple RAID levels in the Dell PERC H755 RAID Controller Card provides users with unparalleled flexibility when it comes to configuring their storage arrays. Different RAID levels offer varying degrees of data protection, performance, and capacity utilization. With this controller card, users can choose the RAID level that best suits their specific requirements.

Improved Fault Tolerance

RAID levels such as RAID 1, 5, 6, 10, 50, and 60 offer various degrees of fault tolerance. These levels distribute data across multiple drives in a way that ensures redundancy and protects against drive failures. In the event of a drive failure, the RAID controller can seamlessly switch to using the remaining drives to maintain data integrity and system availability.

Enhanced Performance

Certain RAID levels, such as RAID 0 and RAID 10, are known for their performance benefits. RAID 0 offers striping, which divides data across multiple drives to improve read and write speeds. RAID 10 combines striping and mirroring, providing both performance and redundancy benefits. With the Dell PERC H755 RAID Controller Card's support for these levels, users can achieve enhanced performance for their storage systems.

Scalability and Capacity Utilization

The support for RAID levels 5, 6, 50, and 60 in the Dell PERC H755 RAID Controller Card enables users to maximize their storage capacity while maintaining data protection. These levels allow for the distribution of data across multiple drives, ensuring that no single drive holds all the data. This results in increased storage capacity utilization and the ability to scale storage arrays as needed.

Reliable Data Integrity

One of the key benefits of utilizing RAID levels in a storage system is the assurance of reliable data integrity. The Dell PERC H755 RAID Controller Card's support for various RAID levels ensures that data is protected from corruption or loss. By distributing data across multiple drives and utilizing parity information (in the case of RAID 5, 6, 50, and 60), the controller card safeguards critical information.

In addition to its support for multiple RAID levels, the Dell PERC H755 RAID Controller Card also boasts a dual-core RAID-on-Chip (ROC) processor, a PCIe 3.0 interface, and support for up to 255 physical drives. These features further enhance its performance capabilities, scalability, and compatibility with a wide range of storage setups.

By combining the power of an 8GB NV cache with support for various RAID levels and other advanced features, the Dell PERC H755 RAID Controller Card offers users a robust solution for their storage needs. Whether it's improving performance, ensuring data protection, or maximizing storage capacity, this controller card delivers on all fronts.
