Collax V-Cube+ is a HA cluster management suite based on a 64bit Linux system and KVM to provide server virtualization. It offers solutions for single virtualization hosts, as well as high availability management on two or more nodes, allowing embedded HA storage using DRBD and iSCSI. By using live snapshots, automatic live migration, and incremental backups, the availability of virtual machines is increased tremendously in case of hardware and software maintenance or even hardware failures. Virtual network switches and the protocols GVRP, LLDP, and RSTP help to set up a virtual DMZ.
Dabo is a three-tier, cross-platform database application development framework, written in Python with the wxPython GUI toolkit. The controls in Dabo's UI are easily bound to data by setting two properties. The business object is designed to afford you complete control over the validation and handling of your data. The cursor classes are abstracted from their backend implementations, allowing for easy support of nearly any backend database. Dabo's design and approach has been inspired by RAD database development tools such as Visual FoxPro, Delphi, and Visual Basic.
