Collax V-Cube+

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.

    Release Notes: With version 29 of Firefox, the elements of the Web administration GUI of Collax servers were erroneous, and the administration of Collax servers was not possible in an appropriate way. This update resolves the issue.

      Release Notes: This update supplies the long term release kernel 3.10.26. A memory leak in the software interface of the Collax fencing device was fixed along with a reboot of VMs by changing the cluster resources of file export to multistate resources. It also fixed an unknown state in virtual HA disks when they were deleted and added again. The JavaVNCViewer, which is used to access a VM's console, is now signed.

        Release Notes: This version supplies kernel 3.2.49 with an update of the kvm module, which fixes I/O timeouts writing to SMB/CIFS shares, fixes Windows VMs with a lot of network traffice freezing, and reduces the boot time of Windows VMs with a lot of RAM. Further, it fixes backup status when backing up VMs to CIFS targets, and corrects support for Eaton UPS. For a 2 node cluster setup, this version provides support for the Collax hardware STONITH device, and it fixes embedded replicated SAN status handling using many VMs.

          Release Notes: This release adds new functions: Managed Save when shutting down a VM, boot order of virtual machines when VMs are started automatically, support for UPS Online Zinto (USB), OCFS monitored automatically for read/write access, and MAC addresses which can be set for virtual NICs in clusters. It fixes a network interrupt when starting a VM, a progress bar when migrating VMs between cluster nodes, and blocked I/O when the buffer cache is written back.

          •  11 Jan 2013 12:24

            Release Notes: This release fixed issues with storage larger than 10TB, a locking timeout when Cluster Share was not writable, resumption of I/O after split brain handling of DRBD devices, live migration of VMs, a problem where removing a Node from a Cluster restarted Cluster Share, a failure to delete the RAM state file after a failed snapshot, and incorrect snapshot dates.
