NexentaStor is a OpenSolaris (not yet) illumos-based storage appliance that I use at work. Nexenta Systems builds a ZFS storage appliance OS that can be installed on whiteboxes that may also have been validated previously to run it. They sell their appliance software as ‘Open Storage appliance’. So is OpenStorage = OSS? Actually I prefer … more
Update 02.2012 – I got some feedback on this blog post and updated some of the content – but since lot’s of things have changed since then regard this as a snapshot of the back then in Autumn 2011. I’m still interested in the progress the Hyper-V modules from Microsoft are doing in the mainline … more
While you can also do quite some LUN mapping on the level of an FC switch I’d like to write here about what there are for possibilities on the level of the OpenSolaris / illumos STMF: Last time I simply added a view to a LUN for everybody which isn’t a good idea if you … more
The first article was a bit specific on NexentaOS 3.x bust most of the things I’ll write here can be used (currently) 1:1 on OpenIndiana and SmartOS Live (once you get it installed on Disk). I’d not recommend using the UNIX shell within NexentaStor, the Appliance OS that comes with a Storage Management System (NMS) … more

Sometimes you just need to see it another way to realize the would be a solution to your struggle: I started using computers with the age of MS-DOS and ran Windows but only knowing there was an alternative (on which I tried but then often struggled since I almost completely switched) which were Unix-like OS. … more
I have preferred Debian and Ubuntu over RHEL mostly because their package collection was much wider. Thus at work I wanted to go with Ubuntu LTS as deal between Ubuntu’s bleeding-edge and a more conservative approach of package versions while Debian Sqeeeze is not yet out. Happy thought I with the arrival of Microsoft hv-Moduls … more
