6Installation Requirements
Windows Prerequisites
Before installing StorNext on a Windows server, verify that the following installation prerequisites
have been met.
A Windows machine that will be used as a StorNext server must meet these requirements.
• 512 MB of RAM minimum for the first two file systems. Each subsequent file system (up to
eight total) either passive or active, must have an additional 256 MB of RAM mi nimum.
• StorNext requires 350 MB of hard disk space for binaries, documentation, configuration, and
log files. If internal metadata is used, approximatel y 2.5 GB of additional hard disk space is
required per 1M fil es.
In addition, each StorNext-supported Windows platform must meet these service pack requirements.
• Windows 2000 — Service Pack 4
• Windows 2003 Server — Enterprise Edition SP1
• Windows XP — Service Pack 2
Red Hat Linux Prerequisites
Before installing StorNext on a Red Hat Linux machine, verify that the following installation
prerequisites have been met.
•Kernel Requirements - To run StorNext on Red Hat Linux, you must use the following kernels:
•For Red Hat 3: 2.4.21 - 37.EL (Update 6); 2.4.21 - 40.EL (Update 7)
•For Red Hat 4: 2.6.9 - 22 (Update 2); 2.6 .9 - 34.EL (Upda te 3)
To verify the kernel information for Red Hat Enterprise Advanced Server, typ e: uname -a
The following is similar to what is shown:
Linux APU 2.4.21-27.EL # 1SMP <date><platform><compiler>
StorNext is distributed as a loadable kernel module. To build the kernel module, the Red Hat
Linux software must be installed with the Linux kernel source and tools, includi ng compilers.
To build and install the StorNext modules, a symbolic link must exist in the /usr/src directory
that points to the kernel source for the running kernel.
Use this procedure to view the symbolic links.
1Change to the /usr/src directory. Type:
cd /usr/src
2To view the symbolic links type:
ls -l
For the Linux 2.4.21-27.EL kernel, the symbolic link is shown as:
linux-2.4 > linux-2.4.21-27.EL
