Network Tidy-Up 2017
At the end of January 2017, new fibre is being installed for HUBS point of presence at Hacklab.
We need to:
- rearrange our hardware to make space at the top of the rack for fibre termination.
- upgrade our router to handle the increased bandwidth that will be made available to us.
We should also take the opportunity to:
- spread our power usage across a second circuit
- tidy-up the power distribution to avoid chains of power strips
- rearrange the shelving for non-rackmount equipment
- consolidate the power connections for the Raspberry Pis to reduce 13A socket usage
New Rack layout
- top-front is reserved for HUBS and fibre termination
- top-rear is needed for Hacklab primary switch, router shelf and cable management
- Hacklab secondary switch can move to mid-rack and be used for servers
- Replacement Hacklab router (assuming a 1U full-depth) can go mid-rack
- fit two high-capacity PDUs, attached to different circuits
New Shelf layout
- Tower PCs should have the same front-to-back airflow as the rack
- Take the top-half or bottom-half of two shelf units, instead of top and bottom of one unit
- Tower PCs can go on front shelf, Raspberry Pis and console can go on back-shelf
- More power strips
- Use a single Anker power supply or 2-3 Ikea USB chargers to reduce cabling for Pis
- Use a dumb gigabit switch to reduce network cabling (Server LAN only, special cases can keep connecting to the rack switch)
- Fit an extra twin 13A socket next to the rack on circuit #1
- Fit two twin 13A sockets next to the rack on circuit #2
- Identify suitable back-boxes for cable conduit: cmsplc.com
- Purchase back-boxes, twin sockets, additional cable
3x twin backboxes (plus 2x twin and 1x single spares for future projects)
- Arrange access to plant room to switch-off power
- Schedule downtime (can be mitigated by running essential systems from another circuit)
Ideal configuration would be a Dell R610 with two power supplies. RAM requirement is modest (1G).
Software is likely to be BSDRP.
