Absorbing a collection of new processing, memory, storage, and networking technologies in a fast fashion on a complex system is no easy task for any system maker or end user creating their own infrastructure, and it takes time even for a big company like Oracle to get all the pieces together and weld them together seamlessly. But the time it takes is getting smaller, and Oracle has absorbed a slew of new tech in its latest Exadata X6-2 platforms.
The updated machines are available only weeks after Intel launched its new “Broadwell” Xeon E5 v4 processors, which have been shipping …
Oracle Steps With Moore’s Law To Rev Exadata Database Machines was written by Timothy Prickett Morgan at The Next Platform.
Cumulus Networks announced today that in conjunction with Dell and Red Hat, it has created a 300+ node OpenStack pod using standard open source DevOps tools to manage the deployment from top to bottom (i.e. from the spine switch down to the compute node). I thought that was interesting enough to justify a quick post.
I visited with Cumulus Linux as part of Networking Field Day 9 and learned two very important things:
The idea of this software stack demo is to take linux-based switches (Dell brite-box
Cumulus-certified hardware running the Cumulus Linux OS) and connect in linux-based compute resources (Dell PowerEdge servers running Continue reading

In the past few months we have seen major outages from United Airlines, the NYSE, and the Wall Street Journal. With almost 5,000 flights grounded, and NYSE halting trading the cost of failure is high. When bad things happen IT personal everywhere look at increasing fault tolerance by adding redundancy mechanisms or protocols to increase robustness. Unfortunately the complexity that comes with these additional layers often comes with compromise.
The last thing your boss wants to hear is, “The network is down!”. Obviously it’s your job to prevent that from happening, but at what cost? Many of us enjoy twisting those nerd knobs, but that tends to only harbor an environment with unique problems. I too fear the current trend of adding layer after layer of network duct tape to add robustness, or worse, to try and fix shortcomings in applications. NAT, PBR, GRE, VXLAN, OTV, LISP, SDN… where does it end!?
The greater the complexity of failover, the greater the risk of failure. We often forget the lessons of our mentors, but keeping the network as simple as possible has always been best practice. As Dijkstra said, “Simplicity is a great virtue but it requires hard work Continue reading
