L5-25152-24 LSI Logic Megaraid 9280-8E 6GB 8PORT PCI Express X8 Low Profile SAS/SATA Raid Controller 512MB Cache And Battery | New Bulk Pack

The L5-25152-24 LSI Logic Megaraid 9280-8E is a PCI Express x8 low-profile SAS/SATA RAID controller. It offers the user high performance and data protection, making it suitable for use in a variety of applications. In this article, we will take a closer look at the features and benefits of this device.

RAID Controller

A RAID controller is a device that manages a set of hard drives and presents them to the operating system as a single logical unit. RAID stands for Redundant Array of Independent Disks. There are several different levels of RAID, each with its own advantages and disadvantages. The Megaraid 9280-8E supports RAID levels 0, 1, 5, 6, 10, 50, and 60. Each of these levels provides a different balance of performance and data protection.

SAS/SATA Support

The Megaraid 9280-8E supports both SAS and SATA hard drives. SAS stands for Serial Attached SCSI, and SATA stands for Serial ATA. SAS is a more robust and reliable technology, designed for use in high-performance server environments. SATA, on the other hand, is a more affordable technology that is suitable for use in desktop and consumer applications. The Megaraid 9280-8E is capable of managing both types of drives, allowing users to mix and match drives as needed.

PCI Express Interface

The Megaraid 9280-8E is designed to be used with a PCI Express x8 slot. PCI Express is a high-speed serial computer expansion bus standard that is used to connect various hardware devices to a computer motherboard. The x8 designation refers to the number of lanes that are used to communicate with the device. The Megaraid 9280-8E uses eight lanes, providing a high-speed, low-latency connection to the host computer.

Low Profile Design

The Megaraid 9280-8E is designed to be installed in a low-profile computer case. This means that it has a shorter PCB (printed circuit board) than a standard RAID controller, making it suitable for use in compact computers and servers. The low-profile design also allows for better airflow and cooling, which can help to prolong the life of the device.

512MB Cache

The Megaraid 9280-8E features a 512MB cache. A cache is a small amount of high-speed memory that is used to store frequently accessed data. By storing this data in the cache, the controller can access it more quickly than if it had to retrieve it from the hard drives. This can significantly improve performance in certain applications.

Battery Backup

The Megaraid 9280-8E comes equipped with a battery backup unit (BBU). The BBU is designed to provide backup power to the controller in the event of a power failure. This ensures that any data that is currently being written to the hard drives is not lost. The BBU also helps to protect the controller’s cache, which can be damaged if power is lost while data is being written to it.

In Summary, the L5-25152-24 LSI Logic Megaraid 9280-8E is a high-performance, low-profile SAS/SATA RAID controller that offers a wide range of features and benefits. Its support for multiple RAID levels, SAS and SATA hard drives, and its fast PCI Express x8 interface make it a versatile and powerful device. Its low-profile design, 512MB cache, and battery backup unit make it a reliable and durable solution for a variety of applications.
