The brief outage was due to a scheduled move of the servers to a separate rack and subnet dedicated to our work with the Center for Information Assurance & Cybersecurity (ciac) at the University of Washington Bothell (uwb), and a11y.com
I am currently exercising the new (to us) equipment and hope to winnow the less than awesome equipment over the next quarter. I spent the last six months finding the best in breed of the surplussed DL385 and DL380 chassis we (work) were going to have recycled. The team and I were able to find enough equipment to bring up one of each with eight and six gigs of memory, respectively. These will make excellent hypervisors for provisioning embedded instances of Slackware, Fedora, RHEL, CentOS, Debian, FreeBSD, OpenSolaris, OpenIndiana, FreeDOS, etc.
When I initially configured this xen paravirt environment, I failed to plan for integration with libvirt, so I am now re-jiggering the software bridges so that they are managed using virt-manager. My experience doing this in the Eastsound lab has proved to be quite rewarding. Once network, storage and memory allocation are handled by libvirt, it will be trivial to automate the process of deploying, reclaiming, and managing these Telecommunications Resources efficiently and effectively using Perl.
The new equipment we racked over the last weekend all has hardware assisted virtualization and is capable of hosting operating systems which have not been patched to communicate with the host hypervisor. This provides a higher level of assurance that guests will receive the full amount of provisioned resources and reduces the likelihood of resource conflicts, should the cluster operations team mistakenly over-commit. It also makes it possible for these nodes to host Windows-based operating systems. Oh, and they will also host these not insignificant things called BIG-IP Local Traffic Manager Virtual Edition (VE) and BIG-IP GTM Virtual Edition.
