Introduction Setting up wireless networking can be a frustrating experience. Available commercial routers vary greatly in their implementation and standards compliance, meaning that compatability between brands of router can be problematic. There are also significant security issues in implementing WiFi netowrks, compounded by the fact that manufacturers rarely update their firmwares and dump support for routers after only a few updates. Thankfully, there are now some great options for installing open-source software on routers so that it’s easier to have cross-compatibility and maintain up-to-date security patches.

Scientific computing increasingly involves handling large amounts of raw data. This is particularly the case for neuroimaging. With increases in processing speed outpacing storage speed, disk i/o has become a limiting factor in many computing applications, especially in multi-user systems. For my consulting work with GreenAnt Networks, I was asked to build a high-speed disk array for scientific computing and virtual machine storage. This is a brief build log and performance test of the outcome.
