Patching HP customized ESXi installs with latest agents and drivers

If you’re running ESXi deployed from custom HP ESXi installation images but you’re not patching the HP utilities inside with each ESXi update, you may be setting yourself up for trouble in the future.  And simply pointing to the VMware repositories won’t update these custom tools —  you also have to point towards the HP vibs […]

Almost two weeks ago now, VMware unwrapped vSphere 5.5 to the public.  The release, which ships later this year, includes a lot of enhancements and some new features for the datacenter.  I won’t lie – 5.5 has a lot more in it for the datacenter than 5.1 enhancements.  And I left VMworld 2013 much more […]

Keeping VMFS datastores thin on 3PAR StoreServ

Earlier this year, I moved a large part of my infrastructure onto HP’s 3PAR StoreServ 7400.  As promised, our initial migration netted us over 50% savings through the thin technologies baked into the 3PAR StoreServ platform.  But one my biggest concerns was how well could 3PAR maintain its lean status over months of operation with […]
