By Greg Schulz, Server and StorageIO @storageio
Keeping in mind that the best server and storage IO is the one that you do not have to do, then second best is that which has the least impact combined with best benefit to an application. This is where SSD, including DRAM- and NAND-flash-based solutions, comes into the conversation for storage performance optimization.
The question is not if, but rather when, where, what, and how much SSD (NAND flash or DRAM) you will have in your environment, either to replace or to complement HDDs. Continue reading When and Where to Use NAND Flash SSD for Virtual Servers
I was fortunate enough to have the opportunity to attend PuppetConf 2013. When I walked into the first keynote session, I was shocked by the size of the audience. Over 1300 people were packed into the ballroom. Another 3700 had signed up to watch the event streaming online. Last year there were 800 people at the conference and only 300 the year before. Obviously, both Puppet and DevOps are hot topics these days. Continue reading Recap of PuppetConf 2013 in San Francisco
Nutanix, one of the fastest growing IT infrastructure startups around, shows no signs of slowing down with their release of Nutanix OS 3.5. For those not familiar with Nutanix, they offer a truly converged virtualized infrastructure. This generally consists of four nodes in two rack units of space, where each node has CPU, RAM, traditional fixed disk, SSD, and Fusion-IO flash built in. Their secret sauce is really NDFS, the Nutanix Distributed File System, built by the same folks that created Google’s File System, as well as a unified, hypervisor-agnostic management interface.

It is the start of VMworld and my during my first days of meetings and briefings I have met up with a few companies like QualiSystems, Rackware, and Intiqua that are focusing on automation. These meetings have further confirmed my thoughts from my previous post that automation has now made it mainstream and will continue to grow from here. I expect more and more third-party offerings that will automate more day-to-day tasks and so much more. This supports my belief that in the large enterprises the lower level support groups are going to be an endangered species that will be replaced by automation, which will put a greater demand on the high-end engineers and/or automation developers. This thought leads me to believe that the future of virtualization support groups will be split between two teams. One will consist of virtual architecture and virtual implementation; the other will be a support group of automation engineers to maintain and build the automation workflows.

When we look at the secure hybrid cloud, there seems to be a missing piece, a piece that is used to validate identity via role based access controls assigned to applications, data, and systems. An identity that allows control of dynamic instead of the normal static firewall rules that are part and parcel of most environments. The software defined data center needs security to move with it and not remain static. Yes we could manipulate the rules on the fly, but those manipulations require that we know who is using a particular VM at a given time and in the case of a server, the VM could be used by more than one user at a time, so we need something more dynamic. Privileged access to data needs to be enforced throughout the stack and not just within an application or by encrypting data. Validating against an identity is a key component of the secure software defined data center and secure hybrid cloud.

See you at the show! The time is almost here where several thousand people from around the world will make this year’s pilgrimage to San Francisco for VMworld 2013. This will be my last post before the start of the show and as people are packing and preparing to leave I wanted to share with you what I think is the way to get the most out of your time at the show.
