On a bit of a shorter note to my previous article/novella1https://blah.cloud/architecture/designing-modern-private-cloud-network/ – I have been moving my lab to a bit more of an “enterprise” style architecture – deploying SRM was in the way for that, so I had the need to set up another vCenter, however this gave the opportunity to move to a […]
Designing a modern multi-tenant DC network
This post is part of the Multi-tenant IaaS Networking course.
Over the last 12 months my posting has been dialled back, this isn’t for lack of wanting or ideas, mainly a lack of time and mental bandwidth. Reason being, I have been designing and implementing a new cloud platform (namely “STC”1https://www.novosco.com/cloud-solutions/single-tenant-cloud) for my employer, Novosco – as with any new service or product this requires […]
Please forward: Change of address
Hi All! Just a PSA type thing today, if all has gone well only the most astute among of you will notice any change – www.mylesgray.com is dead, long live blah.cloud. If i’ve done my homework right and this has all gone flawlessly (here’s hoping) any inbound links to the old domain will continue to […]
My VCIX6-NV exam experience
I’ve been putting off doing VCAP level exams for a long time, probably longer than I should have in hind-sight. But a month ago I took my brave pills and booked what would be my first VCAP level exam: VCIX6-NV. So the date was set and I have been studying in pretty much all the […]
My home datacenter.
I have been meaning to write this for a very long time, finally inspired by seeing Russell Pope’s absolutely insane lab in the vExpert Slack and Mark Brookfield‘s homelab post it started when my lab was a single Dell R710 with 96GB RAM and 2x X5670 procs. The home lab has stopped being a lab […]
Setting up Duo 2FA for Fortigate admin authentication
I protect any account I have with two factor auth, at least the ones that support it (this site for example has 2FA for admin logon), it’s not that inconvenient (especially not with Authy/Duo) and greatly increases security of your critical accounts. Let’s start with the endgame: However, I haven’t protected my publicly accessible firewall […]
Enabling Mini Jumbo Frames (RFC4638) on OpenReach FTTC
I swapped out my single Fortigate 100D at home a while back for a cluster of two in active/passive, as part of this migration, that I have written about before I needed to terminate any DHCP or PPPoE interfaces on a different piece of kit than the clustered firewalls. I have had this in the […]
Replicating SAN on openSUSE with VAAI
This article was written a few years back, but never published – it was some work I was doing in my lab to try and get to grips around the work involved in creating a SAN with synchronous replication built in from scratch. It in no way should be used for production, but rather as […]
VMworld 2016 EMEA: My Sessions
It’s the time of year again for VMworld and now comes the unpleasantness of choosing sessions and fighting them out against each other for time slots, last year my session list was basically completely dominated by NSX sessions. Taken a bit more of a broad view, instead with some cool stuff around service provider networking/administration, […]
Configuring Auto Deploy Stateless Caching in vSphere 6.0
Following on from my previous post on configuring custom ESXi images for PXE deployment, it piqued my interest again in Auto Deploy, now that I have a lab large enough (enough physical failure domains) to justify auto-deploy I figured i’d give it another go. I have chosen to implement stateless caching as it will allow […]
