System configurations
Operating system configurations play a significant role in enhancing Cassandra perform-
ance. On a dedicated Cassandra server, resources must be tweaked to utilize the full poten-
tial of the machine.
Cassandra runs on a JVM, so it can be run on any system that has a JVM. It is recommen-
ded to use a Linux variant (CentOS, Ubuntu, Fedora, RHEL, and so on) for Cassandra's
production deployment. There are many reasons to it. Configuring system-level settings is
easier. Most of the production servers rely on Linux-like systems for deployment. As of
April 2013, 65 percent of servers use it. The best toolings are available on Linux:
SSH
and
pSSH
commands such as
top
,
free
,
df
, and
ps
to measure system performance and ex-
cellent filesystems such as
ext4
and
XFS
. There are built-in mechanisms to watch the
rolling log using
tail
, and there are excellent editors such as Vim and Emacs, and they're
all free!

We will be using a Linux-like system for the rest of the topic, unless mentioned otherwise.
If you are unfamiliar with Linux, there is an excellent topic to cover everything you need to
