Cleaning the Replica Closet
Posted by James B. in Technology on February 28, 2010
If, like me, you have been through all the versions of View Composer and the broker since its introduction, various bugs and broken recompositions will have left you with a large amount of detritus in your VMwareViewComposerReplicaFolder, making it hard to keep an eye on the proper operation of the Composer, and in my case, causing a datastore to run out of space and subsequent operations to fail. Time for a clean up.
This is decently documented here, but how do you know which ones you can delete? Read the rest of this entry »
VDI + Storage = Big Impact
Posted by James B. in Technology on February 25, 2010
Introduction
Virtual Desktop Infrastructure, or VDI, is hot. It’s cool, secure, centrally managed, flexible–it’s an IT manager’s dream.
VDI comes in two flavors: Server-Hosted VDI (centralized, single-user remote vDesktop solution) and Client-Side VDI (local, single-user vDesktop solution).
The advantages of a VDI infrastructure are that virtual desktops are hardware independent and can be accessed from any common OS. It’s also much easier to deploy virtual desktops and to facilitate the freedom that the users require of them. And because of the single-user OS, application compatibility is much less of an issue than it is with terminal servers. Read the rest of this entry »
What Does Your Desktop Service Strategy Look Like?
Posted by James B. in Technology on February 20, 2010
If you believed in ITIL v3, what would your Desktop (as a) Service Strategy look like?
If using VDI technology to deploy Desktop Services is a great idea (according to the alleged market size, and vendor/consumer bustle in that market place, it seems to be so) then how do you do it? Well, according to ITIL, you start with a Service Strategy.
I’m no ITIL kung fu master, and this is by choice because I consider ITIL a minor tool that, at best, needs to be used in conjunction with other tools to do the job and it’s not the be-all or end-all. ITIL’s better than nothing, but it’s not everything. And I have a hunch that ITIL pushers are like other religious groups: generally benign, often nice, thoughtful people, but very sensitive if you dare to criticize their church (itSMF), books or practices.
How does ITIL (seek to) help in developing a Desktop Services Strategy? Read the rest of this entry »
Over Subscribing or Over Capacity
Posted by James B. in Technology on February 15, 2010
There’s been a very interesting set of discussions lately regarding performance anomalies across Cloud infrastructure providers. The most recent involves Amazon Web Services and RackSpace Cloud. Let’s focus on the former because it’s the one that has a good deal of analysis and data attached to it.
Reuven Cohen’s post (Oversubscribing the Cloud) summarizing many of these concerns speaks to the meme wherein he points to Alan Williamson’s initial complaints (Has Amazon EC2 become over subscribed?) followed by CloudKick’s very interesting experiments and data (Visual Evidence of Amazon EC2 network issues) and ultimately Rich Miller’s summary including a response from Amazon Web Services (Amazon: We Don’t Have Capacity Issues)
The thing that’s interesting to me in all of this is yet another example of people mixing metaphors, terminology and common operating methodologies as well as choosing to suspend disbelief and the reality distortion field associated with how service providers actually offer service versus marketing it.

Moved Hosts
I have completed moving the site to my new choice of host, (mt) MediaTemple. This site and a couple of other sites that I have are running in their (gs) Grid Server layer. Let me know if you see anything out of line on here that might be due to the move.
