vExpert 2023 – Subprogram Nominations

VMware annually grants the vExpert award to individuals who have made a special contribution to the VMware community. This can be either through publications, presentations, blogs, or work in the VMware User Group (VMUG). I am pleased to be part of the vExpert community for the seventh year in a row in 2023.

In addition to the common vExpert, there are subprograms for specialized application branches.

I applied for the three sub-programs vExpertPro, Application-Modernization and Multi-Cloud and was accepted in all three categories.

vExpertPro

The mission of the vExpert PRO program is to create a global network of vExperts willing to find new vExperts in their local communities, support them, and mentor them on their way to becoming vExperts.

For this purpose, vExpertPro exist in many regions of the world. I have been a member of this group since 2021 myself and have been confirmed for another year.

vExpert Multi-Cloud

The multi-cloud area covers large parts of the VMware Compute portfolio. The term cloud includes not only the public cloud, but also local data centers (private cloud) and combinations of both approaches (hybrid cloud). This includes numerous products such as vSphere, vSAN, VMware Cloud Foundation (VCF), Aria, VMware Cloud on AWS, Site Recovery Manager (SRM) or vCloud Director (VCD).

I submitted my first application for this relatively new vExpert path in 2023 and was accepted. Many thanks to the business unit for the decision.

vExpert Application Modernization

Application Modernization is all about Tanzu and Kubernetes, as well as the ecosystem around these technologies. The background was described in great detail by Keith Lee in his article “Announcing the VMware Application Modernization vExpert Program 2023“.

Major Updates to vExpert Application Process

VMware has updated the application process for the vExpert program. The application is now possible all year round. Only during the selection process the portal will be closed for about 2 weeks. This is usually in February for the first half of the year and in the July/August area for the second half of the year.

For more details, check out Corey Romeo’s post at VMware vExpert blog.

If you have any questions about the application process or need assistance, please feel free to contact me or any of the other vExpertPro.

An Insight into vSAN-Striping

This article is a result of questions that are asked frequently by my students in vSAN classes. The subject of striping sounds very simple at first, but it turns out to be quite complex once you start going away from the simple standard examples. We shed light on the striping behavior of vSAN objects in mirroring, erasure coding, and for large objects. We also show the different striping behavior before vSAN 7 Update 1 and after.

What is striping?

Striping generally refers to a technique in which logically sequential data is segmented in such a way that successive segments are stored on different physical storage devices. Striping does not create redundancy. In fact, the opposite is true. In traditional storage, striping is also referred to as RAID 0 (note: RAID 0 -> zero redundancy). By distributing the segments over several devices that can be accessed in parallel, the overall data throughput is increased while latency is reduced.

Stripe size or stripe width is the number of segments an object is split into.

With a stripe width of 2, an object of 100 GB, for example, is split into two components of 50 GB each and distributed across two storage devices. This corresponds to a RAID 0.

Striping with stripe width=2
