Consolidating datacenters with Pure Storage FlashArray ActiveCluster

Purity ActiveClusterIn my previous post I briefly mentioned one of my cooler projects of 2020: closing down a datacenter and consolidated it to our other datacenters at Open Line. The complexity of this project was mostly on the network and “BU carve-out” side of IT, but also featured a very cool Pure Storage FlashArray ActiveCluster component. In fact, using ActiveCluster technology ensured that we kept it all very simple from a data migration and risk perspective. Let me explain why we did what we did, but also start with a disclaimer.

Upgrading to ESXi 6.5U1: Conflicting VIBs

Incompatible VIB during ESXi upgradeRecently I’ve been upgrading a vSphere 5.5 environment to vSphere 6.5U1. The vCenter upgrade process is pretty bulletproof by now: the installer is pretty much completely automated. I did run into some issues during the ESXi upgrade, one of which is the fact there were some conflicting VIBs present in the old installations. This would mean the ESXi 6.5U1 upgrade would not start. Time to start hacking in the CLI!

vSphere Replication – Pros and Cons

vSphere Replication ArchitectureThe last couple of months I’ve been busy consolidating a couple of European data centers to one location in The Netherlands. Technically this meant we had to migrate a large number of virtual machines with as little downtime as possible across WAN links with varying speeds (30Mbit up to 500Mbit). There are a number of methods to go about this, but we chose to use the vSphere Replication infrastructure which is included in vSphere 5.x for free. Unfortunately there are a couple of downsides in the management interface which become a pain if you have to manage several hundred replications…

ROBO virtualization with StorMagic SvSAN

StorMagicToday at the VMware Partner Exchange, StorMagic and VMware announced their partnership in bringing high available, low cost server virtualization to the Remote Office Branch Office (ROBO) environments. The StorMagic solution is pretty unique in the fact that it can build a high available, software-defined, vSphere Storage Appliance (VSA) with just two servers compared to the “normal” 3+ servers that other VSA products need. This saves you a lot of €€ or $$ in small locations like the ROBO environments, both in CAPEX  and OPEX.

Hyper-Converged Infrastructure – Meet VSPEX BLUE

VSPEX BlueIn 2014 EMC announced their participation in the VMware EVO:RAIL program which combines storage, networking and VMware compute into a hyper-converged infrastructure appliance: 1 to 4 x86 appliances with internal storage, VMware vSphere and VSAN on top. Connect it to your network, open the management interface and you’re set. Today EMC delivers on that promise with the VSPEX BLUE hyper-converged appliance. The mission of VSPEX BLUE: add simplicity to your IT infrastructure and enable the EVO:RAIL user to easily use all the other EMC offerings like RecoverPoint and ESRS. Let’s see how it does that…
