Marketing in Stealth Mode

Three weeks into my new role as Head of Marketing at D Square it’s time to share my first experiences and findings. First of all I have to say that I’m extremely grateful for the experience. In all my previous roles and opportunities I have been mostly on the execution part of marketing strategy. This time it’s on me to build it from the ground up.

A New Challenge

Prologue

Today I started a new challenge. It’s quite fair to say this could count as the start of the IV-th episode of my career. The first episode was a couple of years in the graphical industry as DTP-operator and Project leader in a Signage company. The second episode would be where I entered the IT world, working for VARs (value added reseller) as Systems Engineer, Implementation Consultant and TeamLead. In episode III, I primarily created technical marketing content or represented vendors at events.

Influencer Marketing for Dummies

What the hell is this new buzzword Influencer Marketing and who is that Influencer here? Haven’t we had enough self-labeled titles? Heck I even call myself a “datacenter specialist” on my LinkedIN profile. What’s a specialist anyway? While I do agree that self-labelling is a weird thing, it’s worth looking at the bigger picture.

New Awesomeness Feature on my list – from Meraki

I sat through quite an amount of vendor pitches. From time to time it’s the small things that differentiate the company and show you their true culture. I keep a list of these small features that have enjoyed me over all these years and I’m ready to share some of them with you.

Make-A-Wish button

The last feature that has been added to my list is the Merake Make-A-Wish button. I first saw it on their presentation for TechFieldDay at Cisco Live in Milan. It’s basically a button at the bottom right corner of EVERY SINGLE PAGE of the User Interface (UI) where you can request for a feature or UI change. It is:

  • NOT a form
  • NOT a phone call
  • NOT an E-mail
  • Just a button that opens a text box!

All-Flash is changing your hardware support

A couple of weeks back at Episode 29 of the In Tech We Trust podcast we talked about the the failure rate of flash drives. Apparently, when handled by smart controllers, it is far less likely than we would think. Some DMs with Vaughn Stewart (Chief Evangelist at PureStorage) later we came to the following statement:

The failure rate of flash drives at PureStorage, 2.5 years after GA, is less than 10 in 1000’s of deployed drives.

This is a truly impressive number. It also helps understand why SolidFire announced “an unlimited drive wear guarantee valid for all systems under current support”. (source: The Register)

The Rebuild

Having a failed disk is not necessarily an issue. We have failover mechanisms for that. The problem is the consequenses of rebuild time. First of all there is the risk of double failure since we put extra stress on the disks for rebuilding parity. That’s why we have created double parity solutions (RAID6). Secondly there is a significant performance drop since both the controllers and the disks are ‘busy’ working on that rebuild. This resulted in up to 24/48hr of keeping your fingers crossed.

Does this still apply for all-flash systems? I mean, isn’t a flash drive exponentially faster than a hard disk? Let’s put it to the test, shall we?

Cisco NBase-T – lipstick on your Cat5e pig

In January of this year I was invited to join the TechFieldDay crew at Cisco Live in Milan. On Monday we got a whole day of Cisco presentations and the rest of the week we had time to spend on the show floor (and a trip to Lake Como!).

The BYOD pipe is just too small

The last presentation for the day was for Peter Jones, principal engineer at Cisco and chairman at the NBase-T alliance. He came to present us MultiGigabit Ethernet (2.5Gbps / 5.0Gbps). My immediate reaction was: who the hell needs a 2.5 and 5.0 GbE standard if we already have 10GbE being rolled out and 40GbE or even 100GbE up and coming?

While 10/40/100GbE are indeed being deployed, this is mainly in the datacenter itself. Interconnects between server clusters or frontned/backend of storage arrays/clusters. But what if we want more than 1GbE to the end-points?

How many of you come into the office and still plug their computer into an RJ45 cable? Most of you will just open their laptop (and tablet and smartphone) and connect straigth to the wireless network, be it the corporate secure Wifi for your laptop or the guest network for your BYO-device. With all these devices connected, our APs can’t keep up with ‘merely’ 1GbE. So we have to scale the bandwidth.

Intel & VMware bring HyperSocket Infrastructure

History

Virtualization has come a long way. In 1987 RAID (redundant Array of Independent Disks) was the first introduction to obfuscating what was really happening on a lower level to one level above. Dozens of layers of obfuscation have been added over the last 30 years that it is today wildly know as virtualization. It wasn’t until VMware came to market with their server obfuscation that this methodology would be adopted by many competitiors.

Intel

The direct result of virtualization was that by adding more layers of obfuscation we were able to increase speeds and lower the overall latency. Lately there has been a great discussion whether or not the obfuscation should happen on top or within the kernel of the virtualization operating system.

VMware and Intel, whom have always had a great partnership, will now come forward with the next step; HyperSocket Infrastructure. The basic concept is that HyperSocket Infrastructure will run completely in the CPU, without the need of an operating system kernel. Today for a process to be completed it traverses the Hypervisor Kernel and the Hardware at least 7 times. The speed increase by doing everything within the processor will be exponential.

VMware has already succesfully reduced their kernel footprint when they changed from ESX to ESXi. This time the software will be even skimmed down so far that it will only use processor instruction sets instead of compiled program languages. The name HyperSocket was chosen to identify that to be able to run this new architecture one will need at least 4 sockets or more (hyper = 4 dimensions in geometry).

Future

It’s not yet known whether this will be in the next vSphere release (v10) or already in the next intermediate update. [note: VSAN was introduced in vSphere 5.5 so HyperSocket Infrastructure could be introduced in v6.6]. 

During the press briefing we already had a view on the future roadmap of Intel and VMware where they showed that HyperSocket Infrastructure is just the first step to a new era of Application Virtualization where the need of DataCenters will completely be eliminated and everything will virtualized within the processors of client devices such as self-driving cars and smartwatches.
