Choosing a VMware NIC: Should you replace your E1000 with the VMXNET3?

[fa icon="pencil'] Posted by Doug Oakes [fa icon="calendar'] August 12, 2015 [fa icon="tags'] Virtualization, VMware, Linux, Microsoft Windows, Networking, Disk Performance

Is your default VMware E1000 network interface (NIC) installed in a virtual machine causing problems with performance?

The best practice from VMware is to use the VMXNET3 Virtual NIC unless there is a specific driver or compatibility reason where it cannot be used. In many cases, however, the E1000 has been installed, since it is the default.

Bug Fix: Start Menu Missing on Windows 10 Technical Preview Build 9926

[fa icon="pencil'] Posted by John Certeza [fa icon="calendar'] August 10, 2015 [fa icon="tags'] VMware, How To Guide, Microsoft Windows

I’ve been using Windows 10 Technical Preview Build 9926 as my daily driver at work on VMware Workstation 11.1.0 and found that my start menu stop working. The lack of a start button drove me crazy and almost sent me back to Windows. Doing some research, I came across another user's "fix" in the comments section of the Windows Blog. But it still didn't solve my issue.

BriForum Comes to Denver

[fa icon="pencil'] Posted by Lewan Solutions [fa icon="calendar'] June 24, 2015 [fa icon="tags'] VMware, Citrix, Microsoft

IT conferences are a great way to catch up on what is new, take classes, and network with peers in the industry. I have been lucky enough to attend great shows like Citrix Summit and Synergy as well as VMware VMworld over the years. The conference for me that always fell just out of reach was BriForum. This year it is all going to change. I am more than a little excited that one of the world's premier IT conferences has chosen Denver, Colorado for this year's US location. BriForum is an independent conference that provides vendor-neutral perspective on current and emerging technologies and services.

What is an IOP and why do I care...disk math, and does it matter?

[fa icon="pencil'] Posted by Lewan Solutions [fa icon="calendar'] June 14, 2015 [fa icon="tags'] VMware, Data Storage, NetApp, Cisco, Disk Performance, Nimble Storage

I'll start by answering the title question first. IOP is an acronym standing for Input Output Operation. It does seem like it should be IOO, but that's just not the way it worked out.

A related fact to note: we generally talk either about total IOPs for a given task, or we talk about a rate - IOPs per Second typically, noted as IOPS with a capital "S". And with that, the Wikipedia portion of today's discussion is complete. Let's move on to why we care about IOPs...

LoginVSI "VSISetup has stopped working"

[fa icon="pencil'] Posted by Lewan Solutions [fa icon="calendar'] March 26, 2015 [fa icon="tags'] VMware, Citrix

One of the real challenges of testing a Virtual Desktop Infrastructure (VDI) is getting enough users to logon to the system to test it at the same time. While load testing should be an essential part of validating a new system, scheduling three or four users to test applications can be challenging. What if you would like to simulate the load of 25 or 50 users? Often, due to the challenges of scheduling and man hours involved load testing gets ignored and you end up hoping for the best on go live day.
