Recently I had a customer decide to literally pull the power cable to test resiliency of their OVS/OVM platform. We have UPS’s installed and with the associated software can and will (I have tested it) shut down machines before power is lost to save corruption. Due to the size of this institute, we run OVM within a VM on OVS and I only use XE. We understand this isn’t a fully supported environment by Oracle, but it the moment it is what it is. Read more

So, I have previously had a SSD in another Laptop, but I had to go back to my Dell Latitude D630, and it still had spinning rust. I decided that a good speed boost and improve battery time a good investment would be a SSD. I managed to get an OZC Agility 4 256GB SSD for ~AU$170.

Recently I have been reflecting a lot on my past. Mistakes I’ve made, things that have gone well, the high’s, low’s and everything in between, and spending less time thinking about the future.

Today I learnt something new. I had not previously heard the term VRF (well not that I can remember anyway.) It means Virtual Routing and Forwarding. Here is a link to the Wikipedia page: http://en.wikipedia.org/wiki/Virtual_Routing_and_Forwarding and a link to the documentation on Cisco’s website: http://www.cisco.com/en/US/docs/net_mgmt/vpn_solutions_center/1.1/user/guide/VPN_UG1.html It looks like it could be really useful.
