Minutes by Dorothea Kazazi.
Github - OSM Operations: Purchase switches for DB4 (#526)
- RJ45 10G
- at least 4 SFP+ ports.
- 1 for upstream
- 1 for bonding
- 1 for DB
- 1 for render
24 ports preference because:
- we plug render and DB servers
- gives us option to split rendering from database
- we already have switches with 4 ports in Amsterdam
Juniper [model not mentioned]
- 10G and 1G ports
- cost less than Cisco.
- 24port: ~ 800 without SFP add-on ports - looked like you had to get them from US
- bonded across 2 switches? yes.
- Command line better than Cisco.
Suggestion: check the temperature handled.
- Concern: power supply particularly high, as it's a PoE only switch.
- Check: how low PSU can you put, as they are hot-swappable (e.g. 350 watt PSU instead of 1400 watt).
- Check for other switch with more SFP+.
- MP model (24 ports, 10 G) doesn't do back to front.
- Price: ~ 400-500 GBP for 4 ports
- Had to get from US.
Discussion on ambient temperature tolerated by switches
- Juniper MP model (24 ports, 10 G) doesn't do back to front.
- Cisco does left-right cooling.
- The air is cool at front of rack only. Exit temperature at back of the rack - air will be blown back down and around the switch, which is fine.
- AMS: PDUs are at the back but sensors are separate module on front of the rack, on a cable.
- AMS: We have an extra sensor, to put at back of the rack.
- Normally 10 oC rise.
- 24,5 oC at the front at AMS.
- 35 oC is the ambient temperature that switches handle.
- Reverse flow: only accept low temperatures.
- A4 models: up to 45 oC (heat-shock territory)
- A5 models: up to 35 oC.
Suggestion: get blanking plate for front of the rack where switch is.
- Price: 2nd hand ~ 2500 GBP from German reseller.
- all 48 ports are 10G (rj45 connector)
- SFP+ ports to do fiber up upstream.
- does left-right cooling.
- Cisco (1 model up from ours): ~ 2500 /switch from 2nd hand reseller.
- Can do VRP and bonded-link.
- Haven't asked for price.
On Border Gateway Protocol (BGP)
- Cisco: doesn't do full BGP - only tiny BGP (1000 routes max/internal BGP only).
- Juniper: Might handle full BGP.
- We decided not to do BGP.
Action: Grant and Guillaume to finalise the model of switches. Switches to go to the Dublin data center. was: Grant to price up 10Gb Switches options for review and decision. [Topic: 10Gb Switches]

Ordering DB and planet servers
- Paul sent proposed specs.
- Used HP hardware still needs to be ordered.
- Drives won't be HP-branded.
- To get Samsung models.
Action: OWG to look at Paul's proposed specs for ordering DB and planet servers for Dublin in next 24 hrs.
DB4 requires advance provisioning of a patch panel.
- The datacenter we're in (DB4), is fairly empty with network providers.
- Provision rack with full capacity required of rack.
- Crazy to front the cost for it.
- Cogent is in DB4.
- 1 time cost (~ 2700 GBP).
Action: Guillaume to email Equinix Dublin about their recent requirement (related to patch panel) and find out about any additional costs (e.g. crossconnect).
Message by Sarah Hoffman (lonvia): I need to talk to Marco again, how the setup is going on their side. But essentially the question was: does OWG want QGIS to sponsor something of the infrastructre. Nominatim related (nor rendering).
On tile usage Paul showed tile traffic analysis that will be shown during his SotM 2021 talk OpenStreetMap Standard Layer: Who uses it?.
- time required
- operational cost (network, bandwidth, hosting space)
- growth without bounds.
- QGIS sponsoring 2 rendering servers for redundancy (marginal cost 1 server) + CDN every 1.5/2 years. Review after 1 year. ~ 5000 EUR/year?
- Having more options, not only OSM-Carto.
Other point mentioned
- Featuring OSM in QGIS is positive, right community.
On Nominatim usage
Suggestion: Sponsoring ~ 1000 EUR/year for Nominatim & reevaluation, as their users might be doing bulk geocoding.
On current policy
- 1 app should do 1 request/sec, it's not per user.
- Auto-enforcecement per IP address, policy is per app. Can't auto-enforce across all.
- Would break usage policy, even without bulk geocoding.
- OWG to make clear to QGIS that if they don't built a rate limit in the software, they'll get auto-blocked. Bulk geocoding is strongly discouraged.
- Paul to work out numbers for QGIS sponsoring.
Any other business
Amsterdam data center
- The OSMF treasurer (Guillaume Rischard) has asked Cogent to switch to 6 month invoicing (saving 25 GBP/month) then will switch back to monthly invoicing, when banking situation goes back to normal.
