vMotion Layer 2 Adjacency Requirement

The topic of vMotion, it’s practicality, and Layer 2 adjacency for vMotion has been a topic I’ve visited a few times over the last several months. The trend got kicked off with a post on vMotion reality, in which I attempted to debunk an article claiming vMotion was only a myth. The series continued with a discussion of the practicality of vMotion, where I again discussed the various Layer 2 requirements for vMotion.

Storage vMotion with RDMs

I recently had a colleague contact me with a question about raw device mappings (RDMs) and Storage vMotion. This colleague was trying to perform a Storage vMotion operation on a VM that also had a RDM attached and was running into a problem where the operation was failing because the destination datastore did not have sufficient space. In this case, the free space was less than the size of the mapped raw LUN, and this colleague couldn’t perform a Storage vMotion as a result. The colleague was surprised; he didn’t expect that behavior.

Some UCS Links

Nothing too terribly new or innovative here; I just had some Cisco UCS-related links I wanted to share with everyone. I hope that you find something useful here.

Technology Short Take #1

I’ve decided to discontinue the Virtualization Short Takes series and replace it with a new series that incorporates items from the networking and storage realms as well. In truth, I was already doing a little bit of that anyway, but this will expand and formalize the coverage a bit. I’d love to hear your feedback on this new series, to help me ensure that I’m providing useful and pertinent information and to help me ensure that I’m presenting it in the most efficient way. So, please speak up in the comments if you have any suggestions for improvement. Thanks!

Changing RDP Settings in VMware View Open Client for Mac

I’ve been using the VMware View Open Client for Mac OS X for a few weeks now, ever since I was approved to participate in EMC’s pilot VDI program. The one thing that I don’t like about the View Open Client is how it leverages the Mac-native Remote Desktop Connection application to make connections to the View hosted desktops. It does so in a way that makes it impossible to customize the behavior of the RDP session—or so I thought.

Help Me Out

Can I ask a favor? In the spirit of transparency and honesty, I want to point out that this is a request for my own benefit, but it shouldn’t take more than a couple of minutes of your time. You see, a local EMC partner named eGroup (here’s their web site) is running this contest to win an iPad. The contest involves taking pictures of an “I love eGroup” sticker in various and interesting places. Since I recently traveled to Cork, Ireland, to support some of EMC’s European partners, I took a few photos while I was in Ireland and I submitted them to the contest.

Enabling RAID 1 on a Mac Mini Server

Today I bought a new Mac Mini running Mac OS X Server to replace an aging home-built Linux server that supports my home network. You might recall that in early 2009 I wrote an article about how I had worked to provide some Ubuntu-Mac integration on the home network. Although the integration has worked well since that time, many of the functions that the Ubuntu server was providing have since been taken over by an Iomega ix4-200d NAS box. It’s the Iomega that now handles all my Time Machine backups and CIFS/AFP file sharing. In addition, I’ve been looking for a way to create a “master” iTunes library for the entire house, and the Linux server with Firefly Media Server, while powerful, just wasn’t doing what I needed it to do. So I figured I’d replace it with an Intel-based Mac Mini running Mac OS X Server. The network services the Linux server is now providing would either be replaced by the Mac Mini or by VMs running on the Mac Mini vis VMware Fusion.
