Dell PERC H745 12GBPS PCI-E 3.0 SAS Raid Front Controller 0T7J9

Cache

The Dell PERC H745 PCI-E 3.0 SAS Raid Controller is equipped with an impressive cache feature that includes 4GB Nv (non-volatile) cache. This cache feature plays a critical role in enhancing the performance and reliability of the RAID controller, making it an indispensable component for users seeking optimal data storage and management capabilities.

Improved Data Processing Speed

The 4GB Nv cache on the Dell PERC H745 ensures lightning-fast data processing speeds. By storing frequently accessed data in the cache memory, the controller can quickly retrieve and serve this information to the system, significantly reducing latency and improving overall system performance. This is particularly beneficial for applications that require rapid access to large datasets or databases, such as financial transactions, database management systems, or virtualized environments.

Enhanced Data Protection

The non-volatile nature of the cache is a key advantage offered by the Dell PERC H745. In the event of a power failure or system crash, the non-volatile cache ensures that data stored in the cache is preserved and can be safely written to disk once power is restored. This feature provides an additional layer of data protection by mitigating the risk of data loss or corruption during unexpected power outages. With the 4GB Nv cache, users can have peace of mind knowing that their critical data remains intact even in challenging scenarios.

Improved I/O Performance

The cache feature on the Dell PERC H745 significantly enhances input/output (I/O) performance. By caching frequently accessed data, the RAID controller reduces the need for time-consuming disk operations, resulting in faster data transfers and reduced I/O latency. This boost in performance translates into improved overall system responsiveness, making it an ideal choice for demanding applications that require high I/O throughput, such as data analytics, virtualization, or video editing.

Cache Coherency

The Dell PERC H745 ensures cache coherency, which means that the data stored in the cache is always up to date and consistent with the data on the disks. This is achieved through sophisticated algorithms that monitor and synchronize data between the cache and disk, ensuring data integrity and preventing any inconsistencies that may arise due to concurrent read and write operations. Cache coherency is crucial for maintaining data accuracy and preventing any potential errors or data corruption issues.

Adaptive Read-ahead

The cache feature of the Dell PERC H745 includes adaptive read-ahead technology. This intelligent caching mechanism anticipates the system's read requests and proactively fetches relevant data from the disk into the cache before it is requested. By reducing disk access time, adaptive read-ahead improves overall system performance by minimizing read latency and maximizing data availability, resulting in smoother and more efficient operations.

Write-back and Write-through Modes

The Dell PERC H745 offers two different caching modes: write-back and write-through. In write-back mode, data is first written to the cache memory and then asynchronously flushed to the disk, providing faster write performance. On the other hand, in write-through mode, data is immediately written to both the cache and disk simultaneously, ensuring data consistency at all times but with a slight performance trade-off. Users can choose the caching mode that best suits their specific requirements, balancing performance and data protection needs.
