I’m VMware Certified on vSphere!


I passed the VCP4 test on Nov 25th, 2009.  I didn’t actually get the VMware certification packet with my certificate until Jan 7, 2010, five weeks later.

See my post on what the VCP4 test was like if you’re interested.

I’m VMware Certified on VI3!


I passed the test on Oct 5th, 2009.  I didn’t actually get the VMware certification packet with my certificate until Jan 5, 2010, three months later.

Stream local desktops with Citrix Provisioning Server (part of XenDesktop)

“Stream a desktop? What is that?”  Well, it’s something like making an image and then deploying it (ala Norton Ghost).  The cool thing is that clients *ALWAYS* PXE boots from the image, nothing is installed locally.

So you can make one image, and then run a whole room or building full of machines off that one image, and never install anything locally.

As I install it and mess around with it, I’m posting notes on my wiki.

Here’s the video that caught my eye.  (Note that Ardence was acquired by Citrix in 2006.)

Notes on using Openfiler with Xenserver

Once you have Openfiler going with iSCSI (read my notes here), then try serving up iSCSI storage with Openfiler to XenServer.  You need shared storage, like iSCSI, to enable some of the “enterprise” features like XenMotion, where you can move running virtual machines from host to host.  Here are my notes on using Openfiler with XenServer.

Openfiler holds its own in tests against dedicated storage appliances

I have access to a couple of different storage arrays, so I decided to see if Openfiler lags them significantly in performance.  Turns out Openfiler does just fine.  In fact, against a Dell/Equallogic PS5000E entry level array, my Openfiler install (running on a Dell 6950) is faster serving up storage for XenServer storage repositories.  It’s a very simple test, and benchmarks always lie, but in a real world test, Openfiler on a Dell 6950 is faster than a Dell PS5000E iSCSI array.

Next up:  Openfiler against NetApp.

Install and usage notes for iSCSI with Openfiler

I’ve been doing a lot of work with Openfiler, a well regarded Open Source Storage Appliance Software package. With Openfiler, you can take “any old” server you have laying around and make a iSCSI, CIFS or NFS file server easily and quickly. Here are my notes on getting Openfiler installed and working for iSCSI. Read more

Neighbors “borrowing” your wi-fi connection? Give them the Upside-Down-Ternet.

Take a little proxy server and add some hacking, and you get the Upside-Down-Ternet. Or Kittenwar.  Or Blurry-Net.  I have to try this.



Hands-on with a Dell/Equallogic PS5000E iSCSI array

I lost a drive in my iSCSI array, so I snapped a few pics as I replaced the drive.  If you’ve never seen what using an array looks like, read on…

I took the VCP410 exam for VCP4 on 25 Nov 2009 and passed!  Here’s my thoughts on the test and how I prepared for it.

“Where did all these hard drives come from?” or why you need shared storage

Shared storage is a way to virtualize storage.  Use a shared storage device (a storage area network) like a Fibre Channel or iSCSI array, and never buy a hard drive in a server again.  Just like virtualization allows you to better utilize the servers you already have, shared storage lets you better use the hard drives you use.  In fact, inventive use of shared storage lets you better use the hard drives you may already have in excess servers.
