Route Server Diagram for an IX

Normally on a peering exchange, all connected parties will establish bilateral peering relationships with each other customer connected to the exchange. As the number of connected parties increases, it becomes increasingly more difficult to manage peering relationships with customers of the exchange.

However, by using route servers for peering relationships, the number of BGP sessions per router stays at two, if the IX has deployed redundant servers.

Ubiquiti launches Speedtest Server/network

https://blog.ui.com/2019/08/13/ubiquiti-launches-a-speed-test-network/

Ubiquiti launches the Ubiquiti Speedtest, the first public test network integrated with enterprise network equipment. Ubiquiti Speedtest comprises a network of test servers and built-in speed test capabilities. Reports include uplink/downlink throughput and latency. Sharing the results is easy via email or social media.

It appears you can run this on a Ubuntu server or VM. They have an installer and a docker image.   You can do browser-based speed tests or their WiFiman App.

Tests may run over LAN, Wi-Fi, or mobile networks. Ubiquiti Speedtest uses Ubiquiti test endpoints and provides automated and manual test target selection. The automated selection uses a combination of geolocation and latency measurements for determining the best servers. The algorithm may use several parallel endpoints for the best measurement accuracy.

Soundproofing your server room

Recently I was asked techniques for soundproofing a server room to keep the noise down in a small to medium-sized office.  Before the discussion dives into the article, there are a few things to keep in mind

1. Don’t let the soundproofing aspect overtake the airflow aspect.  Airflow is critical.
2. Make sure your solution meets fire and building codes.
3. Mass always wins when it comes to soundproofing.

Now on to some ideas.

Ceiling Tiles
Ceiling tiles are typically sound absorbent, but you can get some with higher absorption than others.

Soundproofing on the cabinet
For those of you familiar with high-end car stereos know products like Dynamat and other sound deading materials. The work in two ways.  The first is by adding mass to what the are applied to. Secondly, they are made of materials specially designed to absorb sound. There are many kinds of these on the market. One such product is here on Amazon

Other techniques
Keeping the air conditioner on a decent setting can cause the fans in the equipment not to work as hard. If the device is getting cooled the fans may not have to spin at higher RPMs to move air.  Proper airflow through your cabinets and racks helps greatly with this.  If you have your equipment taking cold air in from the front, where maybe a vent is in front of the cabinet door, this can greatly help.

Supplementing your cooling with a slow moving large fan.  Large fans spinning at low RPMs can move just as much air as smaller fans spinning at higher RPMs.  If your server room needs help this could be an option.

Proper cable management is also essential for airflow.  The better the air moves through the equipment the cooler the equipment will be.  As stated above, cooler equipment means fans are not spinning at high RPMs generating noise.
