Linux Kernel CI for Debian
Github: sammcj/kernel-ci Those of us using technologies such as Docker and BTRFS or simply trying to gain a performance edge on the competition have a lot to gain from the features and performance of recent Kernel updates (especially from 3.18 onwards).
‘Enterprise’ Linux distributions such as RHEL & variants are concerningly out of date when comes to the Kernel.

Over the coming month I will be architecting, building and testing a modular, high performance SSD-only storage solution.
I’ll be documenting my progress / findings along the way and open sourcing all the information as a public guide.
With recent price drops and durability improvements in solid state storage now is better time than any to ditch those old magnets.
Further to my earlier post on XenServer storage performance with regards to directly attaching storage from the host, I have been analysing the performance of various SSD storage options.
I have attached a HP DS2220sb storage blade to an existing server blade and compared performance with 4 and 6 SSD RAID-10 to our existing iSCSI SANs.

The way we work at Infoxchange has changed greatly.

At the end of every year I note down a summary of the best applications, hardware & websites I’ve enjoyed & depended on throughout the year (and often for some time before).

IntroAt Infoxchange we use XenServer as our Virtualisation of choice. There are many reasons for this including:
Open Source. Offers greater performance than VMware. Affordability (it’s free unless you purchase support). Proven backend Xen is very reliable. Reliable cross-host migrations of VMs. The XenCentre client, (although having to run in a Windows VM) is quick and simple to use.
