VMware-Explore EMEA is back

It was almost exactly three years ago that IT experts from all over the world met in Barcelona for the VMware IT trade fair, which was then still called VMworld. Due to the pandemic, the following events in 2020 and 2021 had to be canceled and held virtually instead. Certainly an alternative in times of emergency, but no substitute for the on-site event. Lectures and presentations are only a small aspect. Much more important, on the other hand, is personal contact and networking.

VMworld is now VMware Explore

This year’s event is a new beginning in many aspects. The rebranding may be subject to controversy. VMworld was a constant term within the community and many are still having a hard time with the new brand. That VMware-Explore is a new beginning can also be seen in the visitor numbers. While there were more than 12,000 visitors in Barcelona in 2019, the organizers expected only about half that figure in 2022. Also from the experience from the North America event in San Francisco which remained far below expectations. Surprisingly, demand in the EMEA region is high and instead of around 6,000 estimated attendees, there are over 7,500, not including VMware employees.

VMware vSAN 8 – vSAN on steroids

VMware vSAN was developed about 10 years ago. The year was 2012, when magnetic disks were predominantly used for data storage and flash media was practically worth its weight in gold. It was during this time that the idea behind vSAN was born. Hybrid data storage with spinning disks for bulk data and flash media as cache. Flash devices at this time used the same interfaces and protocols as magnetic disks. As a result, they were not able to unfold their full potential. There was always the bottleneck of the interface.

Today – a more than 10 years later – we have more advanced flash storage with high data density and powerful protocols such as NVMe. The price per TB for flash is now on par with magnetic SAS disks, which has practically replaced magnetic disks. In addition, there are higher possible bandwidths in the network, higher core density in the CPU, and completely new requirements such as ML/AI or containers. The time has come for a new type of vSAN data storage that can fully leverage the potential of new storage technologies.

vSAN Express Storage Architecture (ESA)

Putting it in a nutshell: The vSAN ESA architecture is an optional data storage architecture. The traditional disk group model will continue to exist – even under vSAN 8.

VMware vSAN ESA is a flexible single-tier architecture. This means that it does not require disk groups and no longer distinguishes between cache and capacity layers. It is optimized for the use of modern NVMe flash storage. All storage devices of a host are gathered in a storage pool.

There is no upgrade path from the diskgroup model to ESA. Thus, the new architecture can only be used in greenfield deployments. The vSAN nodes must be explicitly qualified for this. There will be dedicated vSAN ReadyNodes for ESA.
