I’ve been slowly trying to cut down on my online file storage footprint by switching to software and tools that I’m in full control over. For example, I was once a very heavy user of Dropbox and similar tools when it came to transferring files around between my computers, but that could leave my files exposed in the cloud, not to mention it was slow due to the time it took to communicate with the remote server.

Most Intel microprocessors support “HyperThreading” (Intel’s trademark for their implementation of “simultaneous multithreading”) — which allows the hardware to support (typically) two “Logical Processors” for each physical core. Processes running on the two Logical Processors share most of the processor resources (particularly caches and execution units).

Creating a HCI benchmark to simulate multi-tennent workloads. HCI deployments are typically multi-tennant and often different nodes will support different types of workloads. It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules. As with traditional storage, applications are writing to a shared storage environment which is necessary to support VM movement.
