Faster Data Center Transfers with InfiniBand Network Block Device

The storage team of ProfitBricks has been looking for a way to speed transfers between VMs on compute nodes and physical devices on storage servers, connected via InfiniBand, in their data centers. As a solution, they developed the IBNBD driver, which presents itself as a block device on the client...

Real-time Linux has come a long way in the past decade. Jan Altenberg of Linutronix provides an overview of the topic and offers new RTL performance benchmarks in this video from ELC Europe.

Inside Real-Time Linux

Real-time Linux (RTL), a form of mainline Linux enabled with PREEMPT_RT, has come a long way in the past decade. Some 80 percent of the deterministic PREEMPT_RT patch is now available in the mainline kernel itself. Yet, backers of the strongest alternative to the single-kernel RTL on Linux -- the...
