ESXi on ARM – Why?

This is certainly a question I’ve been pondering for a few weeks since the announcements at VMworld 2018 and where Ray O’Farrell presented ESXi running on an ARM Cortex A72 device.  Since my last post covering some VMware news, I’ve been asking – is there any logic in running a hypervisor on an IoT platform… Read more »

VMworld 2018 – Divergent VMware

Nobody likes to be wrong, least of all me, and it’s with fascination that I look at the news coming out of VMworld 2018 this week.  I’m comparing the news to my thoughts on VMware’s future two years ago in my Peak VMware post.  Did we reach peak VMware or did we actually reach peak… Read more »

Rethinking Storage For Microservices

The New Stack had a very interesting article this week that talked about rethinking the way storage is mapped to microservices like containers.  The discussion took me back 12+ months to my own attempts to raise money for a startup that addressed the issues raised in the article.  I’m still not sure that the issues… Read more »

Droplet Computing delivers universal app virtualisation

The IT world is great at delivering technically elegant solutions that intrigue and pique my (and others) interest.  In recent years the entire virtualisation and containers movements have been good examples of this.  Producing something technically interesting doesn’t always lead to a solution that benefits the business.  However, in the case of Droplet Computing, the… Read more »

What is The Container Storage Interface (CSI)?

Despite the initial assumptions that containers wouldn’t need persistent storage, common sense and consensus is moving towards the need to have some sort of continuity with containerised applications.  The reasons are pretty clear.  If a container hosting part of an application dies, it is easier to re-instantiate that container by using any existing data, rather… Read more »

Whatever Happened to VVOLs?

Virtual Volumes, or VVOLs is a technology first introduced by VMware in 2012 to enable the VM-level application of policies to storage.  In the 5+ years since the technology was announced, have VVOLs lived up to initial billing? Background The need for Virtual Volumes was apparent fairly early on in the server virtualisation journey.  Presenting… Read more »

Should I Be Backing Up Containers?

The initial answer to the question, “should I be backing up containers”, would appear to be no.  On the face of it, a container is meant to be a temporary instance of an application component and so not long-lived enough to need backing up.  But digging deeper, there is a need for backup – depending… Read more »

Windows Server, Release Cycles and HCI

The discussion on Storage Spaces Direct (S2D) seems to have generated a lot of interest and a lot of defensive posts. These posts seem to think that what has been written is either wrong or misinformation.  Actually, the issue is poor communication on Microsoft’s part.  However, what’s subsequently been said has left more questions than… Read more »

Block is Not the Solution for Persistent Container Storage

It appears we’re reaching a consensus that persistent storage is needed for containers.  Despite early resistance, with an assumption that containers and their data should be transient, the logic of data persistence is starting to take hold.  To be honest it simply makes sense. Yes, I could keep my data in sync between multiple nodes… Read more »
