The LSI MegaRAID PCIe RAID Controller Card SAS 9260-8i, with the model number L3-25121-74B, represents a critical piece of technology designed to enhance data storage reliability and performance in server and high-performance workstation environments. This RAID (Redundant Array of Independent Disks) controller leverages the power of the PCIe (Peripheral Component Interconnect Express) interface to provide high-speed data transfer and communication with the system motherboard, offering a reliable solution for managing multiple disk drives.
Capable of supporting up to eight internal Serial Attached SCSI (SAS) or Serial ATA (SATA) hard drives, the SAS 9260-8i allows for a flexible and scalable approach to storage configuration. This enables the creation of various RAID arrays to meet different requirements for data redundancy, speed, and capacity. It supports a wide range of RAID levels, including 0, 1, 5, 6, 10, 50, and 60, making it adaptable to various enterprise storage needs, from basic mirroring and striping to more complex nested and parity-based configurations.
At the heart of the SAS 9260-8i is the LSI SAS 2108 RAID-on-Chip (ROC) processor, which delivers the processing power necessary for handling the complex tasks associated with managing a RAID array. This includes the execution of RAID algorithms, management of drive failures, and optimization of data transfers for efficiency and speed. The controller is equipped with 512MB of DDR2 cache memory, enhancing performance by caching frequently accessed data and improving overall system responsiveness.
One notable feature of the L3-25121-74B model is its focus on data protection. It offers options for battery backup units (BBUs) or flash-based cache protection, safeguarding cached data against loss or corruption in the event of a power failure. This ensures that ongoing write operations are preserved and can be completed once power is restored, providing an additional layer of security for critical data.
The LSI MegaRAID SAS 9260-8i includes comprehensive management software, facilitating the configuration, monitoring, and maintenance of the storage array. This software simplifies tasks such as RAID setup, firmware updates, and the management of advanced features like online capacity expansion and RAID level migration, making it accessible for users of varying technical expertise.
In summary, the LSI MegaRAID PCIe RAID Controller Card SAS 9260-8i L3-25121-74B is a sophisticated solution designed for the most demanding storage environments. It offers a combination of high-speed connectivity, flexible RAID support, advanced data protection, and user-friendly management, making it an essential tool for businesses and IT professionals seeking to enhance their data storage infrastructure.
