Last year, Tomi Hakala wrote an article describing how to use NexentaStor to create an NFS share on a commodity x86 box and make that share available to vSphere. Those steps with version 3.0 are still the same with version 3.1:
Install NexentaStor; obtain a unique key; enter key
Create a ZFS volume
Create a folder
Configure NFS Server (use NFS v3)
Note the mount point in which folder is available to NFS client
Open vSphere Client and mount NAS datastore
NexentaStor 3.x is a major release, with many new features, improved hardware support, and many bug fixes over the older Developer Edition including:
In-line deduplication for primary storage and backup
Free for up to 18 TB of overall raw storage capacity (i.e. sum of all ("raw") disks sizes, excepting logs, caches and spares)
Supports easy upgrade to future Community Edition releases and to Enterprise Edition licenses
Support for user and group quotas
The ability to automatically expand pools
NexentaStor 3.x Community ISO CD images can be installed on "bare-metal" x86/64 hardware. VM installed images are also available.

Open source is about very much more than avoiding licensing fees, Simon Phipps contends in his blog Open Source Nurtures Innovation. He argues cogently that absence of the need for an individual or a small group of developers to maintain code libraries (a must with proprietary software) frees writers of software to concentrate on new applications. In the world of open source, " ... instead of being solely responsible for the sustaining of every innovation they add, innovators can contribute their work to the shared code commons and have the sustaining shared by everyone," according to Phipps.

How to set up a one-click HA setting in PostgreSQL's vFabric Data Director is illustrated in Jignesh Shah's blogspot.com post. In some cases the PostgreSQL monitor can correctly diagnose the situation and restart the database. In others the virtual machine itself will need to be shut down, enabling the vCenter Server to start the database on another server. In this instance, DHCP addresses may well be affected, which Shah solves by relying on the virtual hosts format to allow users to find their intended database without regard for which server it is running on.

Simon Phipps, formerly of Sun Microsystems and Oracle, now founder of the startup ForgeRock and director of the Open Source Initiative, recently addressed The Document Foundation's first LibreOffice Conference, where explained that Open Source as a movement does not require a "white knight" to foster and sustain it. Instead, he maintained. Open Source calls for " ... developers willing to collaborate, and a community willing to contribute both time and money." Fortunately, LibreOffice was brought about by the efforts of both factions.
