In Jurassic Park, InGen didn’t build a new dinosaur from scratch. They found a mosquito trapped in amber, pulled one good strand of DNA, and cloned from that source. That amber-preserved DNA sample is what we will make today. That’s exactly what a golden image is in OpenShift Virtualization. You build Windows Server once, preserve […]

Blow on the Cartridge: Refreshing a Dev Database In-Place with FlashArray Volume Overwrites on OpenShift Virtualization
Intro If you’re old enough, you remember the ritual: the game starts glitching, so you pop the cartridge out, blow into it, and slide it back in. Don’t let anyone tell you that it didn’t work… You KNOW it did. But the cool part is the console never moved, the controller was still in your […]
4 Simple Click Through Demos of FlashArray with OpenShift!
Every good game opens with a tutorial level. A safe little sandbox where the game teaches you to jump, crouch, and not stand in the lava before it lets you loose on anything that can actually hurt you. Now, I already see some of you rolling your eyes. The Dark Souls and Escape from Tarkov […]
Beam Me Up, Scotty: Teleporting VMs from vSphere to OpenShift with MTV and Pure FlashArray
Intro I have a major confession to make. I’m not a Star Trek fan. It’s not for a lack of appreciation of the series, it’s more fate that my childhood was filled with Star Wars, Pokemon, Spongebob, and Invader Zim. So when I was researching some fun analogies for this blog, I started to regret […]
Cloning SQL Server on Openshift: How Pure Snapshots Make Dev Environments Disposable
Intro Array-based snapshots are one of the most powerful features in a database administrator’s toolkit. Once a DBA gets a taste of the speed and simplicity of cloning a database without actually moving any of its bytes, they scream “Great Scott!”, grow white hair, and pace around with a frantic Doc-Brown energy their manager finds […]
The Unofficial Beginner’s Guide to OpenShift Virtualization with iSCSI and Pure FlashArray
Intro If the post-Broadcom migration was a prism splitting white light into a spectrum of options, a bright red ray of light would be Red Hat, battle-tested in the enterprise grade linux operating system now moving into the infrastructure platform space. While it might not have the exotic appeal of NVMe/TCP, iSCSI has earned its […]
Wiring Active Directory into OpenShift Without Losing Your Mind
There is a special kind of chaos that appears the moment someone says, “Can we just hook OpenShift up to Active Directory?” On paper, it sounds simple. In practice, it usually means certificates, bind accounts, LDAP filters, group mappings, and at least one moment where you stare at the authentication operator wondering if it is […]
Configuring the Portworx Operator to use Multiple FlashArrays on OpenShift
Journey into the Jungle You’ve just hacked your way into a new, uncharted OpenShift jungle. It’s humid, foreign, and has a faint, lingering scent… “is that the smell of an old used hat?” you think to yourself, “Or perhaps just the musk of a thousand unoptimized containers?” You wipe the sweat from your brow, your […]
Beginner’s Guide to OpenShift Virtualization with NVMe-TCP Pure FlashArray
Intro Back in early 2024, most of us assumed the post-Broadcom migration would look like the flow of the Columbia River into the Pacific Ocean: a massive, singular current of users moving predictably from one giant ecosystem into another. We expected one “winner” to catch the wide swath of people exiting the VMware stage. Instead, […]
