Next-Gen Stuff: Enabling CDP in ESX/ESXi

Now that the veil appears to have been lifted on discussing features and functionality in the next-generation of ESX/ESXi, I thought I’d start out with a brief how-to on enabling Cisco Discovery Protocol (CDP) on ESX/ESXi, both with vNetwork Standard Switches (vSwitches) and vNetwork Distributed Switches (dvSwitches).

This Pretty Much Answers That Question

A couple of days ago I posed this question: is Sun preparing to take on Cisco? The question generated some interesting responses in the comments to the article.

BlueStripe Extends FactFinder to Red Hat Linux

BlueStripe Software, a company I’ve written about a couple of times and who is based in the Raleigh-Durham, NC, area, is launching FactFinder 2.0. I discussed the previous version, FactFinder 1.1, here; and have talked with the guys from BlueStripe on a number of occasions, including at VMworld 2008. I try not to just post press releases or other news information without also adding a little bit of extra information, analysis, or my own thoughts. I have seen FactFinder in action, and it does represent a different way of approaching performance and availability issues. It’s not necessarily a unique way, though, as there are other companies that also work from the application level. I’m confident they don’t use the same technology, but they are working from the application level.

Is Sun Preparing to Take on Cisco?

A while back in Virtualization Short Take #25 I briefly mentioned Sun’s Crossbow network virtualization software, which brings new possibilities to the Solaris networking world. Not being a Solaris expert, it was hard for me at the time to really understand why Solaris fans were so excited about it; since then, though, I’ve come to understand that Crossbow brings to Solaris the same kind of full-blown virtual network interfaces and such that I use daily with VMware ESX. Now I’m beginning to understand why people are so thrilled!

Book Status Report

It’s been about a month since I signed an agreement with Wiley Publishing to write a virtualization-centered book. Since that time, it’s been full steam ahead. Things are going a bit more slowly than I would have liked, but I’ve still met all my deadlines (thus far!) so I can’t really complain. The group of people I’m working with at Wiley are a great group and I can already tell just how much help they will be in making sure that this book is a top-quality product.

I'm Confused

I’m confused. I know, that’s not a terribly difficult thing to do some days. I saw this article on the Windows Server Division weblog about the Release Candidate of SP2 for Windows Server 2008 and Windows Vista and I asked myself, “Did I miss SP1 for Windows Server 2008? I don’t recall hearing about the release of SP1. I guess I should go download it.”

Hyper9 Apparently in Good Shape

With the recent downturn in the economy, it seems like companies on all sides are running into lots of problems. This seems to be particularly true; I’ve heard rumors—nothing confirmed, mind you—that more than one virtualization-related startup is down to a skeleton crew in the hopes they can survive the economic storm.

Open Source VMFS Driver

It looks like my post discussing a universal cluster file system may have been prescient. Shared with me first via Twitter, it appears that a company has already started building an open source VMFS driver. It was also covered here and here.

It's Official: XenServer Available for Free

Although word of this announcement was leaked last week, today Citrix made the announcement official: Citrix XenServer will be available to customers free of charge. Although I was briefed by Citrix on this news the day before word broke, I assured Citrix that I would honor my word and not discuss the news until the embargo expired.
