Servers/Hardware. This is an interesting deep dive into Intel’s “Ice Lake” Xeon SP architecture. KubeVirt, if you’re not aware, is a set of controllers and custom resources to allow Kubernetes to manage virtual machines (VMs). I thought it was useful, so now I’m sharing it with you.

Whether it is redundant hardware or a private hot-site, keeping an environment up and running 99.99% (insert more 9’s here) of the time is a tough job. With a well-planned deployment, and a good infrastructure, companies can efficiently load-balance their IT environment between multiple active, cloud-based, sites.

Ray Budavari—who is an absolutely fantastic NSX resource—has a blog post up on the integration between VMware NSX and vRealize Automation. If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. Servers/Hardware. This one is a bit older (refers to NSX 6.1

As a provider, Expedient has to balance five core resources: compute, storage (capacity), storage (performance), network I/O, and memory. Expedient found that migrating to 10 GbE actually “unlocked” additional performance headroom in the other resources, which wasn’t expected.

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Another good resource is Dan Hersey’s guide to building an SDN-based private cloud in an hour. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware.

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.

We believe that making these GPU resources available for everyone to use at low cost will drive new innovation in the application of highly parallel programming models. These trade-offs have even impacted the way the lowest level building blocks in our computer architectures have been designed. From CPU to GPU.

This is my first time publishing a Technology Short Take with my new filesystem-based approach of managing resources. Servers/Hardware. This is an awesome overview of the OpenStack Folsom architecture , courtesy of Ken Pepple. It’s been a while since my last Technology Short Take (almost three months!); Networking.

The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc. Gartner and others agree - this is the next wave in data center architecture. This permits physically flatter networks.

Converged Infrastructure and Unified Computing are both terms referring to technology where the complete server profile, including I/O (NICs, HBAs, KVM), networking (VLANs, IP load balancing, etc.), The result is a pooling of physical servers, network resources and storage resources that can be assigned on-demand.
