Product Details of the Raid Card

In the realm of data storage and management, RAID (Redundant Array of Independent Disks) controllers play a crucial role in enhancing performance, reliability, and overall efficiency. One such powerful RAID SAS controller is the Dell 51P7W PERC H755, designed to meet the demands of modern storage solutions. In this detailed exploration, we will delve into its specifications, features, and functionalities.

Key SpecificationsRAID Controller

At its core, the Dell 51P7W PERC H755 is a RAID controller, a specialized hardware device responsible for managing and optimizing the performance of a RAID array. RAID configurations involve the use of multiple disk drives to provide fault tolerance, increased storage capacity, or a combination of both.

PCI Support: PCIe 4.0

The RAID controller utilizes PCIe 4.0, a high-speed interface that enhances data transfer rates between the controller and the connected storage devices. This ensures efficient communication and data processing within the storage system.

SAS (Serial Attached SCSI): 12 GB/s

The Dell 51P7W PERC H755 supports SAS technology with a data transfer rate of 12 GB/s. SAS is a robust and scalable interface, commonly used in enterprise environments for its reliability and performance capabilities.

SAS/SATA: 6 GB/s and SAS/SATA: 3 GB/s

The RAID controller provides flexibility by supporting both SAS and SATA interfaces. The SAS/SATA interfaces operate at 6 GB/s and 3 GB/s, respectively. This versatility allows the controller to connect with a variety of storage devices, accommodating different performance requirements.

SAS Connectors: 2x8 Internal

The internal connectivity of the RAID controller is facilitated by 2x8 SAS connectors. This means it can accommodate up to two SAS cables with eight lanes each, providing a robust and reliable connection to internal storage components.

Cache Memory: 8GB NV Cache

An essential feature of the Dell 51P7W PERC H755 is its 8GB NV (Non-Volatile) Cache memory. Cache memory acts as a buffer, storing frequently accessed data for faster retrieval. The non-volatile nature ensures that the cached data is retained even in the event of a power loss.

Write Back Cache: Flash Backed Cache

The RAID controller employs a Write Back Cache mechanism with Flash Backed Cache technology. This enhances write performance by temporarily storing write data in the cache before writing it to the disk. The use of a flash-backed cache ensures data persistence in case of power failure.

Speed and Connectivity

The Dell 51P7W PERC H755 is equipped with a 12GB/s SAS interface, providing high-speed data transfer capabilities. SAS (Serial Attached SCSI) is a technology designed to move data to and from computer storage devices with increased speed and reliability compared to its predecessor, SATA (Serial ATA).

RAID Levels

The RAID controller supports multiple RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and more. Each RAID level offers a different balance between performance, capacity, and data redundancy. Users can choose the RAID configuration that best aligns with their specific needs and priorities.

Data Protection and Redundancy

With RAID configurations, data protection is a critical consideration. The Dell 51P7W PERC H755 employs various RAID levels to provide redundancy, ensuring that if one disk fails, data remains accessible and intact. This is particularly crucial for businesses and enterprises where data loss can have severe consequences.

RAID FunctionalityRAID Levels

The Dell 51P7W PERC H755 supports a comprehensive range of RAID levels, offering users the flexibility to choose the configuration that best suits their specific needs. The supported RAID levels include 0, 1, 5, 6, 10, 50, and 60. Each RAID level provides a unique combination of data striping, mirroring, and parity for optimal performance and fault tolerance.

Max Drive Support: 240

A notable feature of this RAID controller is its impressive capacity to support up to 240 drives. This high drive support makes it suitable for large-scale storage solutions, catering to the increasing demand for expansive data storage in modern enterprises.

RAID Support: Hardware

The Dell 51P7W PERC H755 emphasizes hardware-based RAID support. Hardware RAID offloads the RAID processing tasks from the host system's CPU, resulting in improved overall system performance. This ensures that the RAID calculations and data management are handled efficiently by the dedicated hardware controller.

Advantages of the Dell 51P7W PERC H755

Improved Performance

The 12GB/s SAS interface and the substantial 8GB cache of the Dell 51P7W contribute to a significant boost in overall system performance. Data-intensive applications and tasks, such as database management and video editing, can benefit from the enhanced speed and responsiveness provided by this RAID controller.

Enhanced Data Integrity

Data integrity is paramount, especially in environments where large volumes of critical information are processed. The RAID levels supported by the Dell 51P7W ensure that data remains intact even in the event of disk failure, reducing the risk of data loss and downtime.

Scalability

The Dell 51P7W PERC H755 is designed with scalability in mind. Businesses experiencing growth or those with expanding data storage needs can benefit from the controller's ability to manage a larger number of drives and adapt to changing storage requirements.
