A reader asked: Have you progressed this idea into a production environment? I don’t use NSM platforms as VMs in production, where my “NSM VM” might be deployed alongside other production VMs. Most VM server platforms are designed to share a small number of NICs among many virtual machines for management and serving content. The idea of having a NSM VM writing data while other VMs on the same physical hardware compete for resources doesn’t fit the model. Virtualization is supposed to be helpful for making more efficient use of underutilized hardware.”]
