Diablo: ULLtraDIMM - Installing the Linux Driver

Preparing to install the Linux Driver

For the latest OS and Kernel device driver files, see the ftp site, which contains the ULLtraDIMM Memory-Channel Storage software.

The package consists of two RPM files:

• cli (command line interface)
• kmod (device driver software).

See the latest release notes for more details.

Installing the Linux Driver

Determine the revision of the system kernel with uname -r.

[root@mcs Diablo]# uname -r
2.6.32-358.el6.x86_64

Obtain the version of the device driver that is compatible with the kernel.
Change to the working directory that contains the RPM files.
Install the kmod RPM file with rpm -ivh

[root@mcs Diablo]# rpm -ivh teradimm-kmod-2.6.32-358.el6-1.4.4.105-1.el6.x86_64.rpm
[root@mcs Diablo]#

The installation will create a /dev/tdx directory for each ULLtraDIMM module in the system when the device driver is loaded. For example, for three modules, the results are:

/dev/tda
/dev/tdb
/dev/tdc

Installing the CLI

Install the cli RPM file with rpm -ivh

[root@mcs Diablo]# rpm -ivh teradimm-cli-1.4.4.89-1.x86_64.rpm 
[root@mcs Diablo]#
