View source for ReleaseEngineering/Slave Naming

= Introduction =
On Release Engineering we do builds and tests of Firefox, Firefox for  Android, Firefox OS and Thunderbird. We also do some other tier-2 type of jobs but we use the same hardware used to ship the mentioned  products.
For builds, we build both on real hardware and VMs (in-house & AWS).
For unit and performance tests (aka talos), we build both on real desktop machines, VMs (EC2) and mobile development boards (tegras & pandas).
As we move everything to scl3, we can see the purpose of the machine indicated on the full hostname (try build machines VS release build machines VS test machines VS "Windows" vlan).

== Notes ==
* We only use "try" for ec2 instances since renaming is harder with in-house hosts
* Moving machines from the try vlan to the build vlan will require hostname changes (after the first 'dot')

= Proposed naming =
== Desktop hostname convention ==
P-O-T-XXX

1) P = purpose
* "b-" - for build purposes
* "t-" - for test machines

2) O = OS + instruction size (optional)
* xp32/w732/w864
* w08/w12
** we currently use "w64" for "w08"
* linux32/linux64
** for linux we camouflage the distro
* snow/lion/mtnlion

3) T = Type of hardware
For VMs:
* "ec2" for Amazon
* "vm" if run in-house 
** "vmw" for in-house vmware

For real hardware:
* "hp" for hp machines
* "ix" for ix machines
* "r#" - # depends on the revision of Mac mini that we use

4) XXX = number
Fixed digits allow lexical sorting, but limit to 999 slaves per type.  This is at variance with numbering throughout the rest of Mozilla, where zero-padding is not used.

== Examples ==
Build machine examples:
* b-linux64-hp-XXX
** currently is named bld-centos6-hp-XXX
** bug open to change these - https://bugzil.la/847912
* b-linux64-ec2-XXX
* b-linux64-vm-XXX
** we still use *some* in-house Linux build VMs for esr17
* b-w12-ec2-XXX (15 chars)
** this platform is forward thinking if we build on AWS for Windows
* b-w08-ix-XXX (14 chars)
** currently named w64-ix-slaveXXX
*  b-lion-r#-XXX
<br />
Test machine examples:
* t-linux32-ec2-XXX
* t-linux64-ec2-XXX
* t-linux32-ix-XXX
* t-linux64-ix-XXX
* t-snow-r4-XXX
* t-lion-r4-XXX
* t-mountainlion-r5-XXX
* t-xp32-ix-XXX
* t-w732-ix-XXX
*  t-w864-ix-XXX

== Mobile hostname convention ==
T-XXXX

T = type (e.g. panda or tegra)
Examples:
* panda-XXXX
* tegra-XXXX

== Other infra ==
buildbot-masterXX - for buildbot masters
foopyXXX - for foopy machines that
