E62 – Aruba Did What?

The No Strings Attached Show takes a look at the experience from Aruba Atmosphere 2017 in Nashville. They talk about some of the live demos they saw, including a live update of a controller during the keynote. Give it a listen and hear more from Blake Krone and Sam Clements!


Docker, Modernizing Traditional Applications

At DockerCon, one of Docker’s major pushing was modernizing traditional applications, MTA. They’re specifically targeting containerizing legacy Windows applications, a lift and shift approach by placing an entire Windows image inside a container. Edward Haletky isn’t entirely won over by the draft specifications as outlined by Docker for this process. He does like that Docker introduced certified containers, which goes a long way to alleviate security concerns, and credential specification within PowerShell. The big challenge he sees is identifying applications going forward.


SD-WAN as a Service: Just Give Me an Ethernet Handoff

Phil Gervasi looks at what he saw from TELoIP at Networking Field Day. The company is offering SD-WAN as a service (SDWaaS?). Phil sees the core business benefit of this approach as ease of use and cost savings. The fundamental idea of a managed WAN isn’t all that new to Phil. He sees TELoIP potentially allowing organizations to cancel more expensive MPLS circuits, and instead utilize cheap broadband prices. Since TELoIP utilizes a variety of public internet providers for their service, they are able to achieve collective reliability, with a wrapped in SLA, for much cheaper price. Phil wants to look into some more of the details of transport before making any final judgement. The underlying idea might not be brand new, but TELoIP has an interesting technical approach to the solution.


Wicked Cool! Tech Field Day 14, Here I Come

We’re heading to Boston for Tech Field Day, coming up in May! Matt Crape will be there for his second event, having joined us for a Tech Field Day last year in November. It was an experience to remember, and we hope this event will prove to be just as memorable!


How Docker’s secure software supply chain is key for moving away from the VMware datacenter

Joep Piscaer attended a Tech Field Day Extra presentation from Docker at DockerCon, and got details on how the company is making it easier for enterprises to containerize legacy apps. Joep specifically focuses on software supply chain cycle facing enterprises. He reviews how Docker is removing friction in the supply chain decision making process, and thinks they are doing a better job than VMware.


TELoIP and the SD-WAN Cook-off

Rich Stroffolino wrote up his thoughts from TELoIP’s presentation at Networking Field Day earlier this month. You may not have heard of the company, but they’ve been around since 2002, and have a lot of interesting, and patented, technology. Rich focuses on the capabilities of their VINO SD-WAN solution, which aggregates all available links to offer the best high utilization, performance, and reliability.


The Future of On-Prem in a Cloud World

Rich Stroffolino shared an interview from ZDNet, considering what the roll of the cloud would be in the data center. Rich found it part of an interesting trend in the enterprise, seeing cloud computing as less of a zero-sum game with on-prem, and more of a spectrum. In the interview, Michael Howard and Monty Widenius both actually predict a move back to on-prem infrastructure, as cost and performance are better presented vs the seeming ease of the cloud. It’s an interesting debate, we’ll see how the winds of change impact the role of the public cloud going forward.


What’s New in Networking: Docker at TFD12

Pete Welcher got a look at Docker’s plans to improve their networking from their presentation at Networking Field Day last November. Pete is still trying to wrap his head around what containers mean for networking. But in this post, he raises some prescient concerns. With the proliferation of containers and micro-services, he sees a world with the network getting even chattier, as container-based app components “pass the buck” to other components to actually get work done. It’s an interesting concern, and it’ll be interesting to see how this is addressed and hopefully resolved.


Open19 Brings a new build paradigm to HyperScale Buildouts

At Storage Field Day, Excelero gave some of their presentation time to Open19, an project from LinkedIn to standardize and speed data center deployment. Using a Lego like approach to speed plugin time, their technical specifications allow for delivery of a rack of components in as little as two hours, down from an estimated eight. While this approach might not fit data centers with a lot of legacy equipment, Matt seems to like it for new build outs. Make sure to check out Matt’s piece and their video from the event for more specifics.


Excelero achieves amazing stats at #SFD12

Matt Leib got to see Excelero’s debut at Storage Field Day last month. It’s a presentation that’s gotten a lot of the delegates excited, and Matt is certainly no exception. Their storage solution allows you to access disks in a storage array via their own RDDA, essentially NVME over Fabric. This makes the overhead for disk access negligible. Using commodity networking, this essentially allows the NVMe drives to effortlessly scale. The company demoed getting millions of Iops with minimal latency on hardware costing less than $15,000. Matt summed the presentation up by calling it “[a]stounding technology”.


VMWare NSX Distributed Firewall

At Networking Field Day earlier this month, Kevin Blackburn was introduced to the idea of a VMware distributed firewall. He thinks it’s a perfect example of how their NSX platform can bring additional value to your network by eliminating a lot of the need to physically segment it. Kevin sees NSX as making the network easier to manage, without ceding any control over its operation.


My DockerCon 2017 Day #1

Cormac Hogan attended DockerCon for the first year as purely an attendee, no being tied into an presentations or other events. He found the keynote from Docker CEO Ben Golub and Docker founder Solomon Hykes to be interesting, keying in on the significant announcements. These include the ability for multi-stage builds, to separate build environments from runtimes, as well as LinuxKit, which lets you run a containerized Linux subsystem on any OS. He also enjoyed hearing from Portworx, who presented at Tech Field Day Extra during the event. Check out our video coverage from the event to get more details on their virtualized storage layer for containers.


VMware NSX Unplugged: Networking Field Day

Networking Field Day compared to MTV’s “Unplugged” series? Hey, we’ll take it! Roger Fortier with VMware shared the videos from the event, and found the focused discussions and more relaxed atmosphere led to some truly unique moments. Make sure to check out all of VMware’s presentation, they were able to go really in-depth on their NSX Network Virtualization and Security platform.


SNIA: Avoiding tail latency by failing IO operations on purpose

At Storage Field Day last month, Jon Klaus saw a presentation from SNIA, where they talked about tail latency. These are tiny spikes in latency, 2-10x longer than higher. These can have big impacts, effecting up to 2% of all IO, which is magnified when seen at a hyperscale level. Smaller organizations might simply over provision to lower overall latency so that these spikes still fall within acceptable ranges, but at scale this approach isn’t practical. SNIA presented several ways to overcome tail latency, and Jon shares his thoughts on what he saw.


DockerCon 2017 Keynote: Is the Enterprise listening?

After listening to the DockerCon Keynote, John White wrote up his thoughts on if what he saw indicated greater adoption for Docker in the enterprise. The best use case John saw was security, and the ability to quickly build in numerous compliance requirements, and to have them easily verified in operation. And the new ability to run Linux containers on any platform prevents a technological turf war before it can prevent mass adoption. John has one lingering and poignant question: where does VMware fit into Docker’s plans going forward?


Step by Step – Instalace Solarwinds Virtualization Manager

Karel Novak wrote up a piece reviewing how to install the SolarWinds Virtualization Manager, after seeing it at Tech Field Day in February. The original is in Czech, but we’ve provided the Google Translate versions for our monolingual readers. Check it out here: http://bit.ly/2ogA0nY/


SD-WAN: Redundancy and Optimization

Kevin Blackburn saw a presentation from TELoIP at Networking Field Day earlier this month, and used the presentation as a jumping off point for talking about SD-WAN. TELoIP presented their VINO SD-WAN and SD-Internet solutions during the event. In a lot of ways, the end result of a lot of SD-WAN solutions remains the same, but each company goes about doing it in substantively different ways, which may have different appeal among organizations. For TELoIP, they emphasized using all available internet circuits into a logical bundle of network connections.


Lions and snakes – a quick review of Turbonomic

Raff Poltronieri gives a preview of Turbonomic, ahead of their presentation at Tech Field Day next month. Raff initially became familiar with the company when tasked by a client to find something that could replace VMware vROPS. After some research, he found their solution offered the best price to quality ratio. Raff sees it as a valuable tool for one-man IT shops that need to automate and autotune their infrastructure.


There’s a new cluster filesystem on the block, Elastifile

Elastifile debuted their new file system at Storage Field Day last month, and Ray Lucchesi wrote up his thoughts. It’s designed to support thousands of nodes, exabytes of capacity, and infinite numbers of files, in an effort to make a better cluster file system. It was in development since 2013, and offers some impressive features, including compression, deduplication, and cloud storage tiering. It only caches metadata, and maintains consistency thanks to key-value consensus based algorithm called Bizur. Ray’s not sure how it’ll perform in terms of marketshare going forward, but thinks it shows a lot of great backend engineering to offer a competitive file system right out of the gate.


Programmable ASICs on Software Gone Wild

At Tech Field Day Extra with Cisco Live Europe, Ivan Pepelnjak sat down with Peter Jones, principal engineer at Cisco, for his Software Gone Wild podcast. In their wide-ranging discussion, they talk about why startups fail and NPUs vs ASICs. They then dig into a deeper discussion on the substantive differences and use cases for both. Overall it’s an interesting episode and well worth a listen.
