If a kernel was custom built from
build tree must be available for the Linux driver to reference.
GCC Compiler
The GCC Compiler compiles the Linux kernel and modules. The GCC Compiler
version should match the version that was used to build the running kernel.
Libaio Development Package
The Libaio Development Package is an asynchronous I/O development package
for applications that use
The
benchmark utility (included among the Violin Utilities) uses the
perf_test
asynchronous I/O features to provide high performance asynchronous I/O
benchmarking. For more information on the
asynchronous I/O testing, see
172.
Install both the
libaio
Utilities. The following example installs the required packages on a CentOS 5.5
x86_64 system. At the root prompt, type:
# yum install gcc kernel-devel-`uname -r`.x86_64 libaio-
devel
The second step towards configuring a direct-attached Memory Array system
with a Linux host is to install the Linux driver.
The Linux driver enables a direct-attached PCIe connection between the Memory
Array and the Linux host machine.
In the course of installing the Linux driver, you must decide whether the Linux
driver is to be loaded manually or loaded automatically as a module when the
host boots up.
