Mirage OS v2.0: The new features

The first release of Mirage OS back in December 2013 introduced the prototype of the unikernel concept, which realised the promise of a safe, flexible mechanism to build highly optimized software stacks purpose-built for deployment in the public cloud (see the overview of Mirage OS for some background). Since then, we’ve been hard at work [...]

XenServer Creedence Tech Preview and Creedence Alpha

This morning astute followers of XenServer activity noticed that Citrix had made available the previously announced Tech Preview for Creedence. The natural follow on question is how this relates to the alpha program we've been running on xenserver.org. The easy answer is that the Citrix Tech Preview of XenServer Creedence is binary compatible with the alpha.4 pre-release binary you can get from xenserver.org. From the perspective of the core platform (i.e. XenServer virtualization bits), the only difference is in the EULA. So why run a Tech Preview if you have a successful alpha program already? That's where the differences between a pure...

Setting absolute date based Amazon S3 bucket lifecycles with curl

For my local backup regimen I use flexbackup to create a full backup twice a year and differential/incremental backups on a weekly/monthly basis. I then upload these to a new amazon S3 bucket for each half year (so each bucket corresponds to the a full backup plus the associated differentials and incrementals). I then set the bucket's lifecycle to archive to glacier (cheaper offline storage) from the month after that half year has ended (reducing costs) and to delete it a year after the half ends. It used to be possible to do this via the S3 web interface but the absolute date based options seem to have been...

XenServer Storage Performance Improvements and Tapdisk3

Overview The latest development builds of XenServer (check out the Creedence Alpha Releases) enjoy significantly superior storage performance compared to XenServer 6.2 as already mentioned by Marcus Granado in his blog post about Performance Improvements in Creedence. This improvement is primarily due to the integration of tapdisk3. This blog post will introduce and discuss this new storage virtualisation technology, presenting results for experiments reaching about 10 GB/s of aggregated storage throughput in a single host and explaining how this was achieved. Introduction A few months ago I wrote a blog post on Project Karcygwins which covered a series of experiments and investigations we conducted around storage...
