Break the Network Emulators out of the Cloud

Cisco IOU and JunoSphere Recently both Cisco and Juniper have announced the availability of online resources to provide hands on training over the internet. They have built software emulators in the cloud that can be accessed remotely for a cost. These solutions are based purely around the certification programs and therefore are pretty rigid in the topology that are provided, not to mention the re-occurring cost. http://www.juniper.net/us/en/company/press-center/press-releases/2011/pr_2011_05_16-03_01.html https://learningnetworkstore.cisco.com/market/prod/listSubCatLearnLab.se.work?TRGT=85&/nxt/rcrs/=2559 Rack Rentals There are training providers such as Internetwork Expert (http://www.ine.com/) and IPexpert (http://www.ipexpert.com/) who provide rack rentals based on their training materials. These guy cannot possibly compete going forward. To keep these sustainable they will need to reduce the overhead of building physical racks, providing power and space for the racks. Using e

VMWARE ESXi 5.0 Command line quickies

Hi, It has been a long time since my last posts, but recently I have been working on my home ESXi lab so I thought I would share. I switched over to using Apple Mac just over a year ago, so I don't have a windows machine running by default to run the vSphere client software and generally all I want to do is startup VMs and switch off the ESXi server when I am done. I did some searching and found that I could use vmware vim-cmd if I SSHed into the ESXi server. This need to be enabled at the console, then you can use putty or your tool of choice to connect. Anyway there are several commands the following to me are most useful. List all Virtual Machines vim-cmd vmsvc/getallvms Get a Virtual Machines state (on/off etc) vim-cmd vmsvc/power.getstate Power on a virtual machine vim-cmd vmsvc/power.on Combining command to a one liner you can find out the power on state of all Virtual Machines vim-cmd vmsvc/getallvms && for x in `vim-cmd vmsvc/getallvms|

Dell Latitude D830 SSD Upgrade

Slow Laptop Syndrome I have a LATITUDE D830 : INTEL CORE 2 DUO T7500 4GB Ram from 2008, I did get a fairly high specification at the time, so it has always had pretty decent performance. However I haven't been using it for a while and when I did it seemed slow compared to my Core 5i desktop computer. (I use Windows 7 ultimate with the latest updates) Laptop for Work Now I might be doing a fair bit of travelling to customer sites in the near future and the last thing I want is a poorly performing Laptop, so I decide to ditch all the crap I had on it like iTunes, movies, miscellaneous software and cut back to a basic "work" PC. After all I do have iPhone, iPad and new kindle (soon) for all my multi media needs. I purchased a "Corsair 120GB Force 3 SSD 2.5" SATA-III 6Gb/s Read = 550MB/s, Write = 510MB/s" from ebuyer.com. Now I am guessing that SATA-II rather that SATA-III on the system board, but the price difference between SATA-II and SATA-III wa
