Description
Product Overview of IBM M5210 12GBPS SAS/SATA PCI-E
The IBM 46C9110 Serveraid M5210 Controller is a high-performance SAS/SATA PCIe RAID controller designed to improve the performance and reliability of enterprise storage systems. The controller provides advanced features such as hardware RAID 0, 1, 10, 5, 50, 6, and 60 support, as well as support for up to 1GB cache memory. In this article, we will dive deeper into the features and specifications of the IBM 46C9110 Serveraid M5210 Controller.
SAS/SATA PCIe Controller
A SAS/SATA PCIe controller is a device that connects hard disk drives (HDDs) or solid-state drives (SSDs) to a computer system via the PCIe interface. The controller manages the data transfer between the drives and the system, allowing the drives to be used as a single logical unit or to be organized into arrays. RAID (Redundant Array of Independent Disks) is a technology used to improve the performance, reliability, and availability of storage systems by combining multiple drives into a single logical unit.
Hardware RAID vs. Software RAID
RAID can be implemented using either hardware or software. Hardware RAID uses a dedicated controller card to manage the data transfer between the drives and the system. Hardware RAID provides better performance and reliability compared to software RAID because the RAID functions are offloaded to a dedicated controller, reducing the load on the system’s CPU. Hardware RAID also provides more advanced features such as hot-swapping, online capacity expansion, and battery backup.
Software RAID, on the other hand, uses the system’s CPU to manage the RAID functions. Software RAID is less expensive than hardware RAID because it does not require a dedicated controller card. However, software RAID provides lower performance and reliability compared to hardware RAID because the RAID functions are managed by the system’s CPU, which can be a bottleneck. Software RAID also provides fewer advanced features compared to hardware RAID.
IBM 46C9110 Serveraid M5210 Controller Features
The IBM 46C9110 Serveraid M5210 Controller is a hardware RAID controller that provides advanced features such as:
RAID Levels Support
The controller supports RAID levels 0, 1, 10, 5, 50, 6, and 60. RAID 0 provides striping without redundancy, RAID 1 provides mirroring, RAID 10 provides both striping and mirroring, RAID 5 provides striping with parity, RAID 50 provides striping with distributed parity, RAID 6 provides striping with dual parity, and RAID 60 provides striping with distributed dual parity.
Cache Memory
The controller comes with 1GB cache memory, which can be used to improve the performance of read and write operations. Cache memory is a type of high-speed memory that stores frequently accessed data to reduce the access time to the drives. The controller supports battery backup for the cache memory, which ensures that the data in the cache memory is not lost in case of a power failure.
SAS/SATA Interface
The controller supports both SAS and SATA drives. SAS is a high-speed interface used for enterprise storage systems, while SATA is a low-cost interface used for consumer storage systems. The controller supports up to 16 SAS/SATA drives.
PCIe Interface
The controller connects to the system via the PCIe interface, which provides high-speed data transfer between the controller and the system. PCIe is a standard interface used for connecting expansion cards to a computer system.
Hot-Swapping
The controller supports hot-swapping, which allows drives to be replaced or added without shutting down the system. Hot-swapping provides better availability of the storage system, as it reduces the
