A Collection of Viewpoints on Cisco UCS

A couple of weeks have passed since the announcement of Cisco’s Unified Computing System (UCS), and in that timeframe I’ve collected a number of links to articles and blog posts about UCS. I thought I’d collect them here and try to get a feel from all of the various viewpoints where the industry stands on UCS.

Linux-AD Integration Issue: Persistent Connections

A reader contacted me a short while ago to inquire about a problem he was having with his Linux-AD integration efforts. It seems he had recently added a new domain controller (DC) that was intended to be a DC for a disaster recovery (DR) site. When he took this new DR DC offline in order to physically move it to the DR site, some of his AD-integrated Linux systems started failing to authenticate. More specifically, Kerberos continued to work, but LDAP lookups failed. When the reader would bring the DR DC back online, those systems started working again.

Partner Exchange Schedule

If you’re traveling to Orlando to attend VMware Partner Exchange 2009 and are interested in meeting up with me while we’re there, have a look at this Google calendar. All my meetings and sessions while I’m at Partner Exchange will be listed there, and I’ve updated it for everything scheduled so far. I found that this approach works well after using it quite successfully last year at VMworld 2008 in Las Vegas.

I Tried to Like Postbox, I Really Did

If you haven’t yet heard about Postbox, it’s a new Mac OS X e-mail application built on Mozilla technology that intends to offer a new and different way of working with e-mail. From the Postbox web site, you can look at some of the features the application offers as well as see some screenshots.

Storage Alignment Document

NetApp has recently released TR-3747, Best Practices for File System Alignment in Virtual Environments. This document addresses the situations in which file system alignment is necessary in environments running VMware ESX/ESXi, Microsoft Hyper-V, and Citrix XenServer. The authors are Abhinav Joshi (he delivered the Hyper-V deep dive at Insight last year), Eric Forgette (wrote the Rapid Cloning Utility, I believe), and Peter Learmonth (a well-recognized name from the Toasters mailing list), so you know there’s quite a bit of knowledge and experience baked into this document.

My Current Mac Applications

A colleague recently bought a MacBook Pro. As a switcher, I figured he would need some recommendations on applications to use on his new Mac, and I know it had been quite some time (3 years!) since I’d discussed what Mac applications I use on a day-to-day basis. To kill two birds with one stone, I figured I would post a quick list about some of my recommended Macintosh applications.

Next-Gen Stuff: Verifying the SHA-1 Fingerprint

This post is not necessarily specific to next-generation ESX/ESXi and vCenter Server, but it was prompted by behaviors in these products. (Besides, the truth is that I’m really just trying to be sensationalist and capitalize on interest in the next-generation products.)

Viewing CDP Data on VMware ESX

A couple of weeks ago I wrote about enabling Cisco Discovery Protocol (CDP) on next-gen ESX/ESXi and made the comment that I hadn’t yet found a way to view CDP data from the ESX side. One of the great things about writing a blog is that insightful and knowledgeable readers share some great information with you, and you learn a lot! That’s the situation here.

Hyper9 Goes GA

OK, so I’m a bit slow with this one. (Sorry, folks—writing a book, preparing a presentation for Virtualization Congress, preparing a presentation for the local VMware Users’ Group here in the Raleigh-Durham area, preparing several presentations for my employer’s national sales meeting, and working my full-time day job has me just a bit busy.)
