Virtual Infrastructure Client Opens Off Screen

July 16, 2009 By Josh Townsend 1 Comment

A user reported an issue with one of the VM's in my environment this morning. It seems that an automated process had spun up the CPU to 100% in the Windows guest and the system was deadlocked. I was still at home when I received the message on my BlackBerry, so I fired up the VPN on my Windows 7 laptop, opened the VI3 client and....., um, where is it? The VI3 client icon was in the taskbar, but the app was nowhere to be found - it had opened off-screen where my secondary monitor usually lives. This is nothing new for the VI client - I have experienced it numerous times in the past. … [Read more...]

IBM DS3300 iSCSI Write Performance Solved

June 16, 2009 By Josh Townsend 63 Comments

I have been pulling my hair out with a small VI3 implementation running against an IBM DS3300 iSCSI array. Performance, for lack of a better term, sucked. Granted, the DS3300 is not an enterprise level workhorse of a storage system, but it fit the budget. Read performance was decent from the array, but write performance was terrible, maxing out at 10Mpbs throughput and insanely high latencies on long writes when the system was under load. This led to some long P2V operations, poor guest performance, and some questions from the project sponsors on why I couldn't make the environment … [Read more...]

vCenter Client Passthrough Authentication

March 31, 2009 By Josh Townsend Leave a Comment

I started this blog for a couple reasons: 1.) To help you, my readers, with your virtualization projects, and 2.) To help myself by: a.) raising my online profile as an expert in the community, and b.) To give myself somewhere to keep tidbits of knowledge that I find myself going back to look for over and over again. This post is a 2b. I just built up a new laptop and couldn't remember how to set up pass-through authentication on my VI3 Client. A quick Google search gave me the answer, courtesy of Stu Radnidge's post on nothing other than VirtualCenter 2.5 Passthrough Authentication. This … [Read more...]
