Dell PERC H700 6GBPS PCI-E SAS-SATA RAID Controller 512MB Cache 342-1623

Cache

The Dell PERC H700 PCI-E SAS-SATA RAID Controller is equipped with an impressive 512MB cache. This cache feature plays a crucial role in enhancing the performance and data throughput of the RAID controller. In this section, we will explore the benefits and importance of this cache feature, and how it can greatly benefit users.

Enhanced Data Transfer Rates

With its 512MB cache, the Dell PERC H700 enables faster data transfer rates between the controller and the connected hard drives or solid-state drives (SSDs). This is particularly beneficial in scenarios where large volumes of data need to be transferred quickly, such as in high-intensity server applications or data-intensive workloads. The increased data transfer rates provided by the cache contribute to smoother and more efficient operations, ensuring that critical data can be accessed and processed promptly.

Improved Read and Write Speeds

One of the primary advantages of the Dell PERC H700's 512MB cache is its ability to significantly improve both read and write speeds. The cache acts as a temporary storage space for frequently accessed data, allowing for faster retrieval and transmission. By storing frequently accessed data in the cache, the controller can quickly respond to read requests, resulting in reduced latency and improved overall system performance.

Optimized Workload Handling

The large cache size of 512MB allows the Dell PERC H700 to better handle heavy workloads. When multiple users or applications are accessing data simultaneously, the cache helps in distributing the load efficiently. By storing frequently accessed data in the cache, the controller can reduce the strain on the connected drives, preventing them from becoming a bottleneck in the system. This ensures that even under heavy usage scenarios, the RAID controller can maintain optimal performance levels.

Data Protection and Redundancy

In addition to speeding up data access, the cache feature of the Dell PERC H700 also enhances data protection and redundancy. The controller utilizes a technique called write-back caching, where it acknowledges a write operation as soon as it is stored in the cache. This provides a significant performance boost as the controller does not have to wait for the data to be written to the actual drives before acknowledging the write operation.

However, it is crucial to note that write-back caching introduces a certain level of risk as any unflushed data in the cache may be lost in the event of a power failure or system crash. To mitigate this risk, the Dell PERC H700 incorporates battery backup units (BBUs) or supercapacitors that can preserve the cache contents for a certain period, allowing it to be written to the drives even during power failures. This ensures that data integrity is maintained and minimizes the chances of data loss or corruption.

Improved System Reliability

By safeguarding against data loss and corruption, the cache feature of the Dell PERC H700 contributes to improved system reliability. The ability to quickly and efficiently process read and write operations reduces the likelihood of data errors or inconsistencies. This reliability is particularly crucial in mission-critical environments where any downtime or data loss can have severe consequences. With its 512MB cache, this RAID controller offers users peace of mind by ensuring that their data remains safe and accessible.
