#114 - vSAN Storage Clusters with Kalyan Krishnaswamy!

Recently, Frank published a series of blog posts on GPU resource management. I invited Frank to the show to explain why GPU resource management is different than CPU and memory management in vSphere. Frank goes over all the intricate details, and as always, dives deep into the various constructs involved. I highly recommend reading the articles which are part of the following series, and make sure to also check the tool Frank developed, as this helps visualizing the challenges you may face today, or potentially in the future!https://frankdenneman.ai/ai-infrastructure/https://frankdenneman.ai/understanding-ai-memory/https://frankdenneman.ai/tools/

Recently there was a big announcement about the adoption of vSAN Storage Clusters by Audi. All the reasons for me to invite Kalyan back to the show. During this episode, Kalyan not only discusses what was announced specifically with Audi, but also goes over some of the recently introduced functionality like vSAN traffic seperation, vSphere only clusters support for stretched with vSAN Storage Clusters, and much more.Some of the discussed papers and blogs:Audi case study: https://blogs.vmware.com/cloud-foundation/2025/03/27/audi-introduces-smart-manufacturing-with-vcf-edge/ Lower requirements for vSAN: https://blogs.vmware.com/cloud-foundation/2025/11/14/driving-down-storage-costs-with-lower-hardware-requirements-for-vsan/

I've been on the Virtually Speaking podcast several times, so it was time to invite one of the hosts to the Unexplored Territory Podcast and discuss his favorite topic, hardware configurations, and the bill of materials!John Nicholson goes over all the ins and outs of procuring new hardware and talks about ordering components for existing hardware. We discuss NICs, Switches, Ready Node configurations, Emulated Ready Node configurations, NVMe devices, and much more.During the discussion, various blogs and videos were mentioned, make sure to check those as well!https://blogs.vmware.com/cloud-foundation/2023/07/26/expanded-hardware-compatibility-for-vsan-express-storage-architecture/https://knowledge.broadcom.com/external/article/326476/what-you-can-and-cannot-change-in-a-vsan.htmlhttps://blogs.vmware.com/cloud-foundation/2023/07/27/yes-you-can-change-things-on-a-vsan-esa-readynode/ https://www.youtube.com/watch?v=jjen1ER8ASc https://www.vmware.com/explore/video-library/video/6360757998112

A few episodes ago we had Yves Hertoghs on the show to discuss networking, so I decided it was also time to discuss security. As Chris McCain has been at the forefront of networking and security at VMware for over a decade, it only made sense to reach out and invite him to introduce vDefend!Not only was Chris part of the Explore keynote, but he also delivered various excellent sessions on networking and security in the past couple of years, and I would highly encourage you to watch those as well!Explore 2025 - Demystifying VMware vDefend Distributed Security Within VMware Cloud FoundationExplore 2025 - Building Secure Private AI Deep Dive

In 2025 the first VMUG Connect event was held in the US, and as it was a big success VMUG decided to repeat that formula in Amsterdam, Minneapolis, Toronto, Dallas and Orlando. I invited Brad Tompkins to the show to explain what these VMUG events are all about, and also provide some insights into the world of VMUG.I have the pleasure, and honor, to host a keynote session in Amsterdam at Connect in March. I hope to see all of you there. For more details on pricing, locations, and more, make sure to visit the VMUG Connect website. Also, if you are planning on attending, I would highly encourage you to book asap as we've seen Explore on Tour selling out everywhere...

After Rakesh and I shared the news at Explore, and Explore On Tour, that vSAN would potentially be able to use Fibre Channel as a transport layer, since then the phone has been ringing nonstop. So it was time for me to invite Rakesh and ask him to explain what vSAN over FC is all about. In this episode Rakesh covers the why, the what, but unfortunately the when is still a question. Nevertheless, this episode is a must-listen!Discussed papers/links:​vSAN vs Traditional Storage video​vSAN beats all-flash top storage system

VMware Cloud Foundation 9 has brought the Virtual Private Cloud networking model front and center in the vSphere UI. Not only has it become extremely easy to provide a self-service solution for networking, it comes with a plethora of networking services and capabilities. Maybe even more importantly, it allows networking-noobs (like myself) to consume advanced functionality without having to file dozens of service requests. In this episode, Yves Hertoghs explains what a Virtual Private Cloud is and discusses all the ins and outs around the Transit Gateway, vDefend, subnets and much more.

I had some trouble scheduling guests the past weeks, and as a result, I figured I would try something new. In this episode I go over the various things I announced at Explore and Explore on Tour in London, Paris, and Frankfurt. I talk about VCF Native S3 Object Storage, the enhancements we are planning for Disaster Recovery as well as Cyber Recovery, and I also briefly touch on vSAN on FC. If you like to hear more about vSAN ESA Global Deduplication, make sure to go to this blog on Yellow-Bricks, as it contains the links to the discussion Pete Koehler and I had on the show a while back.

Recently, I read this article about why VCF is the best platform for modern workloads, so I figured I would invite the author, Jad El-Zein. Jad and I discuss all the arguments of why VCF and all components are the perfect destination for containers, or I should probably say your modern workloads.

Recently, I read a fantastic LinkedIn post by Francisco Perez van der Oord, the founder of ITQ, in which he explained why he believes in Broadcom's strategic direction and the VMware portfolio. It was an interesting read, and for me, a great reason to invite one of our most valued partners in EMEA to the show. I want to thank Francisco for taking the time to sit down, as I know he has a crazy schedule.Enjoy the conversation!
