Product Overview of PCI-E Controller

IBM 46C9111 Serveraid M5120 is a SAS/SATA controller that is used to manage and organize large amounts of data in a server. This controller is designed to work with IBM servers, and it provides a cost-effective solution for businesses that need to manage their data efficiently. The M5120 controller has a number of features that make it a popular choice among server administrators.

Features and Benefits

The IBM 46C9111 Serveraid M5120 is a RAID (Redundant Array of Inexpensive Disks) controller that is designed to work with SAS (Serial Attached SCSI) and SATA (Serial ATA) drives. It supports up to 8 SAS or SATA drives, and it can be configured in RAID 0, 1, 10, 5, 50, or 6 modes. This flexibility allows businesses to choose the RAID configuration that best suits their needs.

The M5120 controller has a PCI-E 3.0 x8 interface, which provides high bandwidth and low latency. This means that data can be transferred quickly and efficiently between the controller and the server's CPU. The controller also supports 12 Gbps (Gigabits per second) data transfer rates, which is faster than the previous generation of SAS/SATA controllers.

The M5120 controller has an on-chip cache, which helps to improve performance by reducing latency. The cache can be configured in write-through or write-back mode, depending on the needs of the business. Write-through mode ensures that data is written to the disk immediately, while write-back mode stores data in the cache until it can be written to the disk. Write-back mode can provide better performance, but it also carries a higher risk of data loss in the event of a power failure.

The M5120 controller also supports SAS expander technology, which allows businesses to connect up to 256 SAS or SATA drives to a single controller. This is particularly useful for businesses that need to manage large amounts of data, as it reduces the number of controllers that are needed.


The IBM 46C9111 Serveraid M5120 controller is designed to work with IBM System x servers. It is compatible with the following servers:

  • IBM System x3100 M5
  • IBM System x3250 M5
  • IBM System x3300 M4
  • IBM System x3500 M4
  • IBM System x3530 M4
  • IBM System x3550 M4
  • IBM System x3630 M4
  • IBM System x3650 M4
  • IBM System x3750 M4

The M5120 controller is also compatible with a range of operating systems, including:

  • Microsoft Windows Server 2008 (32-bit and 64-bit)
  • Microsoft Windows Server 2008 R2
  • Microsoft Windows Server 2012
  • Microsoft Windows Server 2012 R2
  • Red Hat Enterprise Linux 5 (64-bit)
  • Red Hat Enterprise Linux 6 (64-bit)
  • SUSE Linux Enterprise Server 11 (64-bit)


Installing the IBM 46C9111 Serveraid M5120 controller is a straightforward process. The controller comes with a user guide that provides step-by-step instructions on how to install and configure it.

Before installing the controller, it is important to ensure that the server is powered off and disconnected from the mains. The controller should then be inserted into the appropriate PCI-E slot on the motherboard. Once the controller is in place, the SAS/SATA cables can be connected to the drives.

After the hardware is installed, the controller can be configured using the IBM Serveraid Manager software. This software allows businesses to configure the RAID settings, monitor the status of the drives, and perform other management tasks.
