Five Days of Ceph at PSA Peugeot Citroën

Last week, I traveled to the
Franche-Comté region of
eastern France on behalf of SUSE, to introduce a group of Ceph novices
to our favorite distributed storage system and to SUSE’s distributed
storage product,
SUSE Enterprise Storage 2.1.

PSA Peugeot Citroën,
usually simply called PSA, is one of Europe’s best-known automobile
manufacturers and one of France’s largest employers, with over 180,000
full-time employees. One of its largest information technology
facilities is the Centre Informatique Groupe PSA in
Bessoncourt, about 40km
from the Franco-Swiss-German border near Basel/Bâle. This facility is
“home” to a group of engineers that my SUSE contact,
Christophe Le Dorze
(whom I had the pleasure of introducing to Ceph a couple of years
ago), described as extremely sharp and pleasant to work with — and
right he is.

New to Ceph, not a problem

Whenever I run a class, what I do immediately after introducing myself
is a quick poll of my attendees. This helps me find out who they are,
what they do in their organization, and what exposure they’ve
previously had to the technology we’re covering in the course. Almost
all were completely new to Ceph, with just two having had some prior
experience. Pas de souci: this didn’t stop anyone from making
excellent progress throughout the course.

Over the course of the first three days, each of my attendees built
their own SUSE Enterprise Storage 2.1 cluster (based on Ceph 0.94
“Hammer”) using our hastexo Academy platform
for course content and interactive labs — which went just as
swimmingly as our courses based on other Ceph platforms, once we had
ironed out a few kinks
in SLES12SP1 guest images. We covered basics of RADOS, Ceph Mons and
OSDs, RBD, radosgw, and CephFS, and quickly progressed to
benchmarking, performance tuning, and advanced topics such as
erasure-coded pools, tiers, and overlay pools. On days 4 and 5, we
also had a chance to cover OpenStack integration, ranging from RBD
integration with Glance, Cinder and Nova to managing Swift endpoints
via Keystone-integrated radosgw.

Solid tech, solid product

As I mentioned halfway through the course, introducing Ceph to people
for whom the technology is entirely new is always a great pleasure —
the technology is just so beautifully engineered and makes intiutive
sense, almost no matter where you look. Sure, it does have its kinks,
but for the most part it’s truly logical and fun to work

SUSE’s Ceph product, SUSE Enterprise Storage 2.1, is also a solidly
packaged, proverbial quality work of German engineering (although, of
course, SUSE’s Ceph team happens to be spread out over Germany, the
Netherlands, the United States, and Australia). It has recently added
Crowbar-based bare-metal deployment support and some excellent iSCSI
gateway functionality. For the latter, you should
check out this SUSE whitepaper.

Interested? Give it a whirl!

If you want to give SES2.1 a try (you really should), we’ve made
that easy for you too:
is an OpenStack Heat template that you can deploy to any OpenStack
public our private cloud (OpenStack Juno or later).

As seen below, using the template is super simple: deploy the stack
with heat stack-create or the Orchestration component in the
OpenStack dashboard, set your SLES12SP1 and SES2.1 eval keys (which
you can fetch from
here and
respectively), wait for the stack to spin up, log in, and then
ceph-deploy away!


And of course, if you’d like to take a full Ceph Fundamentals course
on-line, self-paced, with fully interactive labs on a real multi-node
system, you should
check out our HX212 class, available
