Footprint Reduction
May First/Peope Link has servers located in two cabinets: XO and Telehouse. In order to save costs (and electricity) we are exploring the possibility of combining both cabinets by moving the servers in XO to our cabinet in Telehouse.
Inventory
Following are the electricity using machines in each cabinet. RAM used is calculated by kvm-status
to find out how much RAM is allowed to virtual machines on each server as a very rought measure of capacity.
XO
Login to either odetta or ochs (see remotely turning on/off servers).
Server name | RAM Used/Capacity | Notes | |
clr | 27 / 32 | Move as is | |
malaka | 56 / 64 | Move as is | |
pietri | 26 / 32 | Move as is | |
franz | sr | Move as is | |
ottorene | tachanka/mfpl | Move MF/PL guests, combine with pianeta, move as is | |
| NA | console | Retire |
| ptp | Retire/Combine with severo | |
| 14 / 16 | former FIGHT server | Transfer guests to new server, retire* |
| NA | onsite backup | Retire (barron can handle onsite backup |
| tenant | Move to virtual guest in Telehouse | |
| tachanka | Combine with ottorene, move as is |
Telehouse
Run olName all
from pdu-console@pdu.mayfirst.org
to get a list.
Server name | RAM Used/Capacity | Notes | Proposed Plans |
parsi | 46 / 80 | ||
cleaver | 62 / 128 | ||
robideau | 4 / 4 | backup and console | |
florence | 62 / 64 | ||
vilma | 47 / 64 | ||
NEW SERVER | 80 / 128 | Takes guest from axiom, negri, bolivar, ottorene | |
barron | onsite backup | ||
cafiero | switch | ||
severo | 56 / 64 | ptp | |
baubo | yesmen (new) | ||
anna | tachanka | ||
| 29 / 32 | Transfer guests to new machine*, retire | |
| NA | retired, praxedis | Retire or move praxedis, retire |
| yesmen (old) | Retire ? | |
| 25 / 32 | Transfer guests to new machine*, retire |
Servers already turned off:
- fred
- ken
- A new server with 128GB RAM could handle the capacity of axiom, bolivar and negri (67 GB). These are our only remaining machines with only 2 disks.
Electricity Usage
Our current electricity usage at Telehouse is about 1KVA (we are contracted for 2KVA - so we are at 50%). The circuit holds more than 2KVM, so we should not need to maintain a cushion.
Virtual Guest Reduction
To help with the combination of guests onto servers, we can make a big impact on reducing memory usage by combining several of our single purpose guests into one guest running docker.
Candidates include:
- stallman (Roundcube webmail)
- cero (Horde webmail)
- lucius (ownCloud)
- mcchesney (live.mayfirst.org, calc.mayfirst.org, im.mayfirst.org)
- moses (support.mayfirst.org)
- paul (freeswitch)
- sankara (icecast)
- toussaint (icecast)
- galeano (meet.mayfirst.org)
In addition, the following guests could be retired:
- peltier (we just need to move a few media wikis to a regular MOSH)
- swartz (big blue button)
And some special cases:
- boggs and kerr are both dedicated to occupy groups, most of whom are no longer active. We should figure out how to remove the inactive groups.
