UCS vMedia Configuration and Boot Order

Just a quick note on Cisco UCS vMedia. If you have configured a remote CD/DVD from a remote ISO and UCS manager is showing the image is 'mounted' but your server is still stuck in a PXE/Netboot loop... It may be helpful to know that your regular boot order policy in your service profile doesn't [...]

ZFS on Linux resilver & scrub performance tuning

Improving Scrub and Resilver performance with ZFS on Linux. I've been a longtime user of ZFS, since the internal Sun beta's of Solaris Nevada (OpenSolaris).

Openstack and PaaS; Love a good geek rift!

I've been in the bay area, CA for a couple of weeks now (excluding my cheeky jaunt to vegas!) and even though i'm now on vacation, it's been the perfect place to watch the OpenStack Havana Drama unfold; Mostly stemming from this catalyst; http://www.mirantis.com/blog/openstack-havanas-stern-warning-open-source-or-die/ Well (for me, anyway) especially this bit; Too many times we [...]

Pivotal Cloud Foundry Conference and Multi-Site PaaS

So I recently got back from Pivotal’s first Cloud Foundry conference;   as I’m not a developer, I guess by the power of deduction I’ll settle for cloud leader. While there, this newly appointed cloud leader, erm, lead a pretty popular discussion on multi-site PaaS (with a focus on Cloud Foundry, but a lot of [...]

Google Nexus 4 Smartphone

But this guy pretty much 100% summaries my thoughts for me, right [...]

It used to just be paperwork that took time to work out!

With ‘Bring your Own Device’ will come ‘Bring your Own Data’

A friend put me on to http://owncloud.org/, which despite it's awful naming (oooh cloud! That's new and good isnt it? snore!) is an open source implementation of some of Apples iCloud featureset (from what I can see) which can be hosted anywhere you want. At first I was about to hit download, as a techy, [...]

Virtualization Principals with Paravirtualized IO

This isn't really a proper post, more just some little notes I can point people too (which I guess, technically is a blog post, ahh well!). So Virtualisation, have used VMWare products (most of) and Xen previously in production, with Virtualbox my desktop-virt product of choice for testing on my local machine for some years [...]
