Data ONTAP Upgrade

To be honest, there are times when using Mac OS X can be difficult. With the overwhelming installed base of Windows and the attention of the media darling Linux, vendors will often provide instructions on how to do something with Windows or Linux, but not from Mac OS X. Sometimes the Linux instructions work, but many times they don’t, and the Windows instructions typically involve running some sort of Windows executable that won’t, of course, run on Mac OS X. What is one to do, then?

BladeCenter H Woes

This IBM BladeCenter H installation I’ve been working on with another engineer for the last couple of days is not going as smoothly as we both would have liked. I don’t know if this is indicative of the BladeCenter H chassis itself, or if it’s just me. While some would say it’s just me, I suspect it’s a little of both.

Cocoalicious Update

Cocoalicious, the native Mac OS X front-end to the del.icio.us bookmark system, has been updated and now sports (in my opinion) a cleaner user interface that bodes well for future development.

Trying Two New Apps

I just started working with two new Mac OS X applications and wanted to mention them here. Both applications are pretty good applications, and worth a try if you have a need for their particular functionality.

Windows Server 2008 Beta 3 on ESX Server

I just finished installing Windows Server 2008 Beta 3 on ESX Server 3.0.1. Despite the fact that the amount of time I spend designing, implementing, and supporting Microsoft products continues to decrease, this is an important product release and one with which I need to be very familiar. In addition, I’m particularly interested in how developments in the Windows Server product line will affect Active Directory (AD) and AD integration scenarios. Once I have had the opportunity to create an AD structure based on Windows Server 2008, I plan to write a new set of articles on Linux and Solaris integration.

OpenBSD 4.1 on ESX Server 3.0.1

Having tested a couple of the previous releases of OpenBSD on various versions of ESX Server (OpenBSD 3.8 here and version 3.9 here), I decided to test OpenBSD 4.1 on ESX Server 3.0.1. I didn’t really expect any problems at first, but then I stumbled across this article describing a problem between OpenBSD 4.1 and ESX Server 2.5. Fortunately, it appears as if that problem does not affect ESX Server 3.0.1.

LUN Clones vs. FlexClones

My recent article on how to provision VMs using FlexClones prompted a reader to ask the question, “What about using LUN clones?” That’s an excellent question, and one that I myself asked when I first started using some of the advanced functionality of Network Appliance storage systems. I had expected that this question would come up, and so I’d already begun preparing an article discussing LUN clones vs. FlexClones. My thanks go to Aaron for prompting the discussion!

NetApp FlexClones with VMware, Part 2

Part 1 in our series on NetApp FlexClones and VMware discussed in greater detail some of the advantages of using FlexClones for VM provisioning. In that article, we saw that using FlexClones can greatly reduce both the storage required for new VMs as well as the time required to provision new VMs, especially when the storage needed by the VMs is large. Both of these advantages can be very compelling.

Resizing Disks Inside Guests

While I would love to be able to say that this procedure I’m going to describe for resizing disks inside guest VMs is new or unique or original, I can’t. I’m sure that lots of smart people out there have been down this path before, and more than a couple of them have probably written up good instructions on how to do it. I’m including this information here partly for myself (in the event I need it in the future), and partly because the information fits in with a lot of the other information I have here on VMware and related technologies.

NetApp FlexClones with VMware, Part 1

The ability to quickly and easily create new virtual servers in VMware VirtualCenter (using templates and cloning) is a key feature that benefits a lot of VMware customers. A new server running Windows Server 2003 R2 in less than 10 minutes? Who wouldn’t like that functionality? (Some other day, perhaps we’ll discuss that very question.)
