Potential Problem with ESX 3.0.x and VirtualCenter 2.5

Heads up—I’ve been alerted to a potential problem when using ESX Server 3.0.x with VirtualCenter 2.5. Quoting from this VMware KB article:

NetApp Snapshot Support

For readers that didn’t already know this, Snapshots on NetApp-hosted CIFS shares are automatically and transparently recognized by Windows versions that support the “Previous Versions” tab. I believe this functionality is native on Windows Server 2003 and an add-on for Windows XP, but I’m not 100% certain. Either way, this means that users can easily recover files from NetApp Snapshots from within the Windows GUI.

Quick Guide to Setting up NetApp Deduplication

I’m relatively new to NetApp deduplication (formerly A-SIS), so this article won’t be an advanced treatise on NetApp deduplication or its deep inner workings. Instead, this is intended to be a quick guide to setting up NetApp deduplication for others, like myself, who may be familiar with Data ONTAP but not necessarily deduplication.

Only Thin Provisioned in the Beginning

A niggling doubt about thin provisioned disks was placed in my head when I read Duncan’s article on a Storage VMotion problem; in that article, a statement is made that ESX Server 3.5 no longer supports thin provisioned disks. Intrigued by that comment, I started doing some digging to see if that was actually the case. I was unable to find any concrete statement one way or the other.

Cyberduck and Interarchy Revisited

At the start of 2007, I wrote a pair of articles on Mac FTP/SFTP clients, lamenting the performance of the open source Cyberduck application and eventually settling on Interarchy as my replacement product.

NetApp OmniGraffle Stencils

If I had one complaint about being a Mac OS X user, it would be that there is no Visio equivalent on the Mac. Yes, OmniGraffle is an awesome program; this is especially true for version 5, which can open native Visio drawing (VSD) and shape (VSS) files. That one new feature was, to me, worth the upgrade price.

Some Useful HP Blade Information

Some time last week, one of my NetNewsWire subscriptions turned up an article titled “HP VirtualConnect” from Brent Ozar. It turns out that Brent’s blog, while heavily SQL Server-oriented, has a few nuggets of HP Blade information:

Virtualization Sea Change?

I received word this morning that Embotics, a maker of software intended to help manage the virtual machine lifecycle, had been selected to participate in the Microsoft Startup Accelerator Program. I’d never heard of this program, but it sounds interesting based on the Embotics press release:

VI Toolkit for Windows in Beta

Within the last few days, VMware has released a beta version of the VI Toolkit for Windows, a set of PowerShell cmdlets that enable users to do some very useful, very powerful things with Microsoft’s new scripting language. Personally, I’ve never been a good programmer and so learning a new language like the PowerShell scripting language will take some time (something I have precious little of these days), but I do hope to be able to become more familiar with these tools and how to use them for my benefit and the benefit of my customers.

After a brief mention of this topic in Virtualization Short Take #4, the battle between Citrix, Microsoft, and VMware over memory overcommitment has heated up.
