#STBY Cisco Clock Issue – 18month life failure

Migrating From a UCS FI6248 to Mini 6324

I have the luxury of working for the most awesomest storage and Cisco VAR in the world, as their Principal Technologist. We have a few different groups of engineers. Our networking team staked claim on the existing UCS and FI6248 Fabric Interconnects that we have in our lab for break/fix testing.

This meant that our demo and test VMware environment needed a new home. We really didn’t NEED another full set of big daddy FI’s in the lab, and the big boss didn’t want to buy another full set of FI6248s. We simply need a test environment for me to give classes with, that’ll support up to 600 VMs. A UCS Mini was perfect. This is how I got passed the hurdle of migrating the configuration from a FI6248 to FI6324.

Thoughts on Certifications (aka I passed my CCNP DataCenter)

CCNP Datacenter

6 required exams. 21 days.

I didn’t make a large hoopla when I passed my CCNP Datacenter and CCNA Datacenter last week. I’ve always wanted to be Cisco certified. Though, I always felt anything but CCIE was sort of bunk. (still do, though I have met MANY incapable CCIE) I’m no smarter today. I’m no better of an engineer today. The only thing I know better today, is where a few documents are. I’ve been using the Nexus product line since the 5010’s first came out a few years ago. I play with 5548s in customer environments from time to time, same with 6248 FIs.

Tip #3: Adding additional networks to VMware Fusion 4/5

So, you are studying for a networking certification. Maybe CCNA or CCNP, maybe F5 or Juniper. You need multiple interfaces to run GNS3/Dynamips or your favorite networking tool. Alas, the default configuration of VMWare Fusion just has the basic VMnet1 and VMnet8. Here is how to fix that!
