When infrastructure (server or storage) fails in a traditional, physical environment, there is typically resulting downtime while a complex and lengthy recovery from backups is reconstituted. In most cases, this requires time obtaining and setting up identical replacement hardware, then additional time to recover the operating system, applications and data from the backups.

I am excited to announce that Scale has officially moved ICOS 4.2 out of beta and into limited availability (meaning that our support team can upgrade customers for use in a production environment)! The theme for this release was more advanced networking functionality and included features such as:
Support for VLAN tagging
Support for adding multiple network interface cards (NICs) to VMs
Connect or disconnect network interface cards (NICs) on VMs
In the video below, I walk through the simple setup of a VM to VM private network which highlights these features.
For more information on this release, please see the release notes which can be found on the partner portal and customer portal. If you have any questions or would like to see a demo of this new functionality, please give us a call!
As a follow up to my last post, Virtualization So Easy Even a Four-Year-Old Can Do It, I want to continue to focus on the simplicity that virtualization can and should be. Yet explaining what virtualization actually is, can be a complicated task to anyone not in technology. The hypervisor splits the computers. Huh? They are virtual machines! That just sounds like bad 3D from the 90’s. There are many machines in one. That just sounds like too much information (and awkward). You as an IT professional should be able to explain to your grandma not only what you do, but virtualization as well. Let me share the best ways I’ve learned over the years for doing just that.

Previous posts in this series have discussed the ease of use and high availability design goals of the HC³ platform, as well as the hardware and high level software architecture. Now, lets roll up our sleeves and walk through how ICOS (Intelligent Clustered Operating System) takes a set of independent compute nodes with independent storage devices and aggregates them into a single pool of compute and storage resources that are managed as a single, redundant, highly available system.
Once the Scale HC³ cluster nodes are racked and cabled and configured with physical network connectivity, the cluster formation process takes multiple nodes (currently 3 or more) and logically bonds them together to act as a single coordinated system in a process that completes in a matter of minutes.
