 ===== Summary =====
-We have 6 vossi machines.They are used daily for all parts of the development process - building Ceph alone takes more resources than a usual developer laptop, and running it uses even more I/O, CPU, and RAM. Having a consistent environment in which engineers can make changes, build, and test speeds up the overall dev process.
-vossi01 Runs Fedora 31
+We have 6 vossi machines.  They are intended to be used as developer playgrounds since they have system resources far greater than the usual Developer laptop.
+===== Installed OSes =====

+===== Use Suggestions (for devs) =====
+Here are some suggestions to maximize the use of the system resources these machines provide.
+==== Scare off other devs :) ====
+Create an MOTD that displays whenever anyone logs in:
+''vim /etc/motd''
+<code>
+*******************************************************************************
+                                STOP!
+           This machine was promised to Joe Dev for exclusive use.
+Check https://wiki.sepia.ceph.com/doku.php?id=hardware:vossi&#installed_oses to
+          see if there are any others available for exclusive use.
+      Let dmick or akraitman know if you need a different OS installed.
+                               Thanks!
-vossi02 Runs Ubuntu 18.04
+*******************************************************************************
+</code>
-vossi03 Runs Centos 8
+==== Building Ceph on an SSD ====
+If you want to build Ceph on an SSD (the main OS and ''/home'' are on a spinner), find an SSD that's not in use (''sd{b..e}''), then:
-And vossi04, 05 and 06 Runs RHEL 8
+<code>
+mkdir -p ~/src
