Switch Mishmash
Last week, I stumbled upon an interesting problem. One of the projects I'm working on as an astronomical sensor grid, putting out about 2.6Gb/s of data per sensor station, coupled to a central super computing infrastructure. This system is still in the buildup/tender phase, so the network consists of networking equipment of various brands, to test out what the differences are and how well they work together. There are only 5 sensor stations at the moment, so the total amount of data is manageable. In the future the total data stream will grow to about 1Tb/s, to be processed real time.
High Speed Firewalling in Linux
In this age of virtualization, cluster and grid applications, the load on the server network interface tends to increase. Multi-homed servers were rare not more than 5 years ago, nowadays servers come with 4 NICs pre-installed. This, of-course, increases complexity and network cost. Today I made a proposal for a couple of servers with more than 10 Gigabit interfaces. With the current state of technology, we are approaching the break even point for 10 Gigabit network interfaces. This year will see the breakthrough of 10Gigabit over copper in the datacentre.
