Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

In my 23-year career as a software developer, I've noticed an imbalance of diversity in the world of technology - especially when it comes to hiring women in tech. Here's a look at ways I try to make a difference in my community and the industry as a whole.

as the father of a young mixed race girl, here in the US I am fairly passionate about diversity
I'm not Australian born myself (was barely more than a toddler when my parents migrated here) and copped a fair bit of flack for that at school.

Do you have to solve those sociological issues in order to get more young girls of color interested in STEM or to get more women feeling inclusiveness within the industry, today? No.
Point taken. Thanks for sharing your insights Lucas.

As you note, women aren't well represented in the tech field. However, skin color is relevant in that women of color are marginalized even further. While women as a group potentially experience sexism --  women of color are simultaneously exposed to both sexism and racism. The theory of intersectionality discusses this experience, but the easiest way to explain is that women of color are facing more bias and a more complex social dynamic.

I couldn't have said it better, Lucas. Thank you for your insight. Women of color face both sexism and racism in the US. I'm actually speaking at Amazon re:Invent on intersectionality in tech. I hope to see you there!

Prepare for the CompTIA Network+ exam by learning how to troubleshoot, configure, and manage both wired and wireless networks.

The task has taken me a year to figure out, so I would like to share tips with you, in case you run into the problem and come across this article, searching for it.

The article describes step by step how to validate the SRA software certificate once installed on the Site Recovery Manager server. I hope it will be very useful for all administrators of virtualized environments.

The following article describes how to recreate the VMDK file of a virtual machine. It is important that this file is always in the datastore where the VM is stored, because if the VM is not present, it will not be able to turn on and an error I hope it is very useful for everyone.

What are some good heuristics when considering the ratio of total Guest vCPUs to Host Physical Cores(ignoring HT/SMT); 2:1, 3:1?
The more involved followup might be how to measure core contention on a Hyper-V Host

Also when does core count matter more vs frequency, I guess the answer is workload dependent.
20 Cores @ 2.5Ghz (50k Ghz)
16 Cores @ 3.7Ghz (59.2k Ghz)

Microsoft used to have a set of values for VM counts depending on processor core count and GHz. Those recommendations have essentially been sidelined due to the fact that CPU is pretty much not the bottleneck anymore.

That being said, we go for GHz before core count as a rule because it's just that much faster to get the smaller vCPU count VM's threads through the CPU pipeline.

And finally, a wide core count would indeed be needed for multi-threaded applications like SQL to get through the pipeline as soon and as wide as possible.

Hi Ryan,

Thanks for your message.  I'll flesh it out a bit and then submit it again.

I have a related question:  If I have a topic/article/post that I only want to post to the Paessler Topics page, does it still go through independent review?  I tagged "paessler" on several articles, but haven't been asked to review or approve them.  Who decides what can appear on our topics page?

(um, to avoid confusion, yes, I'd like to post this article to several topics, after it meets the requirements for an article.  My question is more a hypothetical one, in case I have things to post only to the Paessler topics page at some point).

Thanks for your help!
