More Information for the HPE 749680-B21 Smart Array Controller

In the ever-evolving landscape of technology, data management and storage solutions play a pivotal role in ensuring optimal performance and reliability for businesses. The 749680-B21 HPE Smart Array P244br emerges as a key player in this domain, offering a cutting-edge 12GBPS 2-Ports Int SAS Raid Controller with 1GB FBWC (Flash Backed Write Cache). In this comprehensive guide, we delve into the intricacies of this RAID controller, exploring its features, benefits, and how it contributes to efficient data handling.

Understanding the Basics

What is a RAID Controller?

RAID, which stands for Redundant Array of Independent Disks, is a technology used to combine multiple physical drives into a single logical unit. A RAID controller is a crucial component that manages the data storage process across these drives, ensuring data protection, performance optimization, and fault tolerance.

Overview of the 749680-B21 HPE Smart Array P244br

The 749680-B21 is a RAID controller developed by Hewlett Packard Enterprise (HPE). It falls under the Smart Array P244br series, featuring advanced capabilities to meet the demanding requirements of modern data centers and enterprises.

Features and Specifications
  • 12GBPS Data Transfer Rate: One of the standout features of the 749680-B21 is its impressive 12GBPS data transfer rate. This high-speed capability is essential for handling large volumes of data efficiently, making it ideal for applications that demand rapid data access and processing.
  • 2-Ports Int SAS (Serial Attached SCSI): Equipped with 2-Ports Int SAS, this RAID controller ensures a reliable and robust connection between the storage drives and the server. SAS technology brings advantages such as high-speed data transfer, scalability, and improved performance, making it a preferred choice in enterprise storage solutions.
  • 1GB FBWC (Flash Backed Write Cache): The inclusion of a 1GB FBWC is a significant enhancement for data reliability. Write caching is a technique that accelerates write operations by temporarily storing data in volatile memory. The flash-backed aspect ensures that in the event of power loss, the cached data is not lost, contributing to data integrity and preventing potential data corruption.
  • RAID Levels Support: The 749680-B21 supports a variety of RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and more. This flexibility allows users to choose the RAID configuration that best suits their specific needs, balancing factors such as performance, redundancy, and capacity.
Benefits of the 749680-B21 HPE Smart Array P244br
  • Enhanced Performance: With its 12GBPS data transfer rate and support for various RAID levels, the 749680-B21 significantly boosts overall system performance. This is particularly advantageous in scenarios where data-intensive applications and workloads are commonplace.
  • Data Protection and Redundancy: The RAID configurations supported by this controller, especially RAID 1 and RAID 5, provide data protection and redundancy. In the event of drive failure, the system can continue to operate without downtime, ensuring data availability and business continuity.
  • Improved Storage Management: The 2-Ports Int SAS connectivity and advanced management features of the Smart Array P244br simplify storage management tasks. This contributes to streamlined operations, reduced complexity, and enhanced overall efficiency in the data center environment.
  • Reliability in Write Operations: The integration of a 1GB FBWC adds an extra layer of reliability to write operations. By temporarily storing write data in the flash-backed cache, the controller ensures that data is not lost during unexpected power outages or system failures.
