Dell 405-AAUZ SAS PERC H745 12GBPS PCI-E 3.0 4GB Nv Cache Raid Front Controller

Interface: PCI-E 3.0

The Dell SAS PERC H745 PCI-E RAID Controller is equipped with the latest PCI-E 3.0 interface, offering users a myriad of benefits and ensuring speedy and efficient data transfer. With its increased bandwidth and improved performance, the PCI-E 3.0 interface is an essential feature for users who require high-speed data processing and storage capabilities.

Improved Bandwidth

The PCI-E 3.0 interface provides significantly higher bandwidth compared to its predecessors, allowing for faster data transfer rates between the RAID controller and the connected storage devices. This enhanced bandwidth enables users to handle large amounts of data more efficiently, resulting in quicker backups, seamless data migration, and improved overall system performance.

Reduced Latency

One of the crucial advantages of the PCI-E 3.0 interface is its reduced latency. The lower latency ensures that data is transferred with minimal delay, enabling near-instantaneous access to stored information. This feature is particularly beneficial in mission-critical applications where even the slightest delay can have significant consequences.

Future-Proof Technology

The implementation of PCI-E 3.0 in the Dell SAS PERC H745 RAID Controller ensures compatibility with current and future storage devices that utilize this interface. By adopting this forward-thinking technology, users can rest assured that their RAID controller will seamlessly integrate with upcoming storage solutions, allowing for easy upgrades and expansion of their storage infrastructure.

Enhanced Scalability

The increased bandwidth and improved performance of the PCI-E 3.0 interface enable greater scalability for users. With higher data transfer rates, it becomes easier to connect multiple storage devices to the RAID controller, expanding the overall storage capacity of the system without sacrificing performance. This scalability is particularly advantageous for businesses and organizations that deal with ever-growing amounts of data.

Cache: 4GB Nv Cache

The Dell SAS PERC H745 RAID Controller features an impressive 4GB Nv Cache, providing users with a host of benefits and significantly enhancing the controller's performance. With its generous cache size, this feature ensures faster data access, improved overall system responsiveness, and increased reliability.

Accelerated Read and Write Speeds

The 4GB Nv Cache plays a vital role in accelerating both read and write speeds of the RAID controller. It stores frequently accessed data in the cache memory, allowing for near-instantaneous retrieval when required. This results in reduced latency and faster data access, translating into improved application performance and reduced waiting times for users.

Optimized Workload Performance

By leveraging the 4GB Nv Cache, the Dell SAS PERC H745 RAID Controller optimizes workload performance. It intelligently caches data based on usage patterns, ensuring that frequently accessed information is readily available in the cache. This intelligent caching mechanism minimizes disk I/O operations, reducing the strain on the storage devices and maximizing overall system performance.

Data Protection and Reliability

The large cache size of 4GB enhances data protection and reliability for users. In case of power failures or unexpected system shutdowns, the Nv Cache retains critical data temporarily. This feature ensures that data is not lost or corrupted during such events, as it can be written back to the storage devices once the system is back online. With this added layer of protection, users can have peace of mind knowing that their valuable data is safeguarded.

Improved RAID Rebuild Times

In the event of a drive failure in a RAID configuration, the 4GB Nv Cache significantly speeds up the RAID rebuild process. By temporarily storing the data required for the rebuild, the controller can quickly reconstruct the RAID array, minimizing downtime and reducing the impact on system performance. This feature is particularly crucial in environments where uninterrupted operation is critical.

Front Controller: 1

The Dell SAS PERC H745 RAID Controller boasts a front controller design, providing users with seamless accessibility and convenience. With its front-mounted interface, this feature ensures easy access to the controller's functions and simplifies maintenance and management tasks.

User-Friendly Interface

The front controller design offers a user-friendly interface that allows users to interact with the RAID controller effortlessly. The front-mounted interface typically consists of LCD screens, buttons, and indicators, enabling users to monitor the controller's status, configure settings, and perform various management tasks without having to access the back-end of the system. This intuitive interface enhances usability and simplifies day-to-day operations.

Streamlined Maintenance

With a front-mounted controller, maintenance tasks become more streamlined and convenient. Users can easily swap or replace drives without having to power down the entire system or struggle with cables at the rear of their server. This feature saves valuable time during maintenance operations and reduces the risk of accidental disconnections or damage to other components.

Efficient Troubleshooting

In case of any issues or errors, a front controller allows for efficient troubleshooting. Users can quickly access diagnostic information and error logs directly from the front interface, enabling them to identify and resolve problems promptly. This feature minimizes downtime and ensures that any potential issues are addressed in a timely manner.

Improved Cable Management

The front-mounted controller design also contributes to improved cable management within the server. By connecting the RAID controller to the front of the system, cable routing becomes more organized and less cluttered. This not only improves airflow and system cooling but also makes it easier to identify and trace cables, leading to faster installations and upgrades.

Part Number: 405-AAUZ

The Dell SAS PERC H745 RAID Controller is identified by its unique part number, 405-AAUZ. This alphanumeric code serves as a crucial identifier for users and ensures compatibility when purchasing or replacing the RAID controller.

Accurate Identification

The part number, 405-AAUZ, accurately identifies the specific model of the RAID controller. When users need to purchase additional or replacement controllers, they can simply provide the part number to ensure they receive the correct product. This eliminates any confusion or compatibility issues that may arise when dealing with similar but distinct models.
