Description
Product Overview of the Dell 3KDWX PERC H755 RAID Controller
The Dell 3KDWX PERC H755 is a high-performance RAID (Redundant Array of Independent Disks) controller designed to optimize data storage, handling, and retrieval within server systems. With a data transfer rate of 12 Gigabytes Per Second (GBPS), an
8 Gigabyte (GB) NV cache, and utilizing Peripheral Component Interconnect Express (PCI-E) 4.0 and Serial-Attached SCSI (SAS) technologies, this controller offers enhanced performance and reliability for data management in server environments.
Data Transfer Rate: 12 Gigabytes Per Second (GBPS)
The 12 GBPS data transfer rate of the Dell 3KDWX PERC H755 RAID Controller ensures swift and efficient data movement between the
connected storage devices and the server system. This high data transfer speed is crucial for handling large volumes of data and improving overall system performance.
8 Gigabyte (GB) Nv Cache
The inclusion of an 8 GB NV cache (Non-volatile Cache) within the RAID controller enhances data access speeds by temporarily storing frequently accessed data. This cache helps reduce latency and enhances the efficiency of data retrieval, especially for frequently used information.
Peripheral Component Interconnect Express (PCI-E) 4.0
Utilizing the PCI-E 4.0 interface, the Dell 3KDWX PERC H755 RAID Controller ensures high-speed communication between the RAID controller and the server’s motherboard. The PCI-E 4.0 technology offers increased bandwidth compared to its predecessors, optimizing data transfer rates and system responsiveness.
Serial-Attached SCSI (SAS) Technology
The use of SAS technology in the RAID controller allows for the connection of high-performance SAS drives. SAS drives are known for their reliability, scalability, and high data transfer rates, making them ideal for enterprise-level storage solutions.
RAID Configuration and Redundancy
The Dell 3KDWX PERC H755 RAID Controller supports various RAID configurations, enabling users to create arrays for data storage with different levels of redundancy and performance. Common RAID configurations include RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), and RAID 10 (mirrored striping). These configurations offer a balance between performance, redundancy, and data protection.
