EP23 – Lightbits Labs: NVMe Flash Performance Commoditization via NVMe over TCP – with Kam Eshghi



In this 23rd episode of the TECHunplugged Podcast we welcome Kam Eshghi, VP of Strategy & Business Development at Lightbits Labs. This episode was recorded live at Dell Technologies World 2019 (early May 2019) in Las Vegas.

Lighbits Labs have developed a software-defined storage solution leveraging NVMe over TCP. Their solution allows the disaggregation of storage from compute by offering DAS performance with enterprise-class data services, combined with massive scalability.

A sizeable part of the founding team was behind DSSD, a storage solution which was later purchased by Dell EMC. DSSD was one of the very first storage architectures leveraging NVMe drives, which gives some confidence about Lightbits Labs NVMe over TCP concept. Lightbits Labs was founded 3 years ago and went out of stealth mode in April 2019, so we’re really thrilled to get prime time with them!

During the course of the discussions, podcast co-host Max Mortillaro (@darkkavenger) talks with Kam about the product architecture, its concepts and the use cases for NVMe over TCP.

Show schedule:

  • 00:00 Presentations, introduction to Lightbits Labs and NVMe over TCP
  • 02:00 Addressing the challenge of scalability of DAS and performance of traditional architectures
  • 03:30 The genesis of NVMe over TCP, and why NVMe over TCP is relevant today
  • 05:20 Kam states that no specific drivers are needed, and that Lightbits Labs made its source code available
  • 05:45 All of the intellectual property of Lightbits Labs resides on the target side; Kam also mentions that Lightbits Labs sell a hardware solution called SuperSSD, and that they also have an optional accelerator card
  • 06:22 Max & Kam discuss about partnerships & go to market strategy: software-only, via Dell OEM, or via the Lightbits SuperSSD appliance
  • 08:00 Kam: « All you need to get started is a server with NVMe drives and a standard Ethernet NIC »
  • 08:30 Let’s talk architecture and data services
  • 09:45 Kam mentions a « Global FTL » – that has Max interested in understanding how the internal logic of NVMe SSD drives is managed
  • 12:30 More insights into data services
  • 13:45 Understanding the customer base and use cases for Lightbits Labs: SaaS companies, Service Providers, etc.
  • 15:40 Talking about data protection, replication, and availability
  • 16:30 Application use case: distributed databases (Cassandra, MongoDB, etc.) and High-Performance Analytics workloads, and over all anything that requires high performance and operates at scale
  • 18:00 Max’s usual « WOW » / speechless moment; Kam shares his excitement about adopting customers, not only Hyperscalers but also Private Cloud initiatives in with Enterprise IT organisations
  • 19:00 Since Lightbits Labs is block-based, Max raises the question as to whether there are any plans to offer managed services in the plan, if it makes sense at all
  • 20:15 Covering the topic of licensing models
  • 21:09 What about the optional acceleration card? Kam explains that the card sits on storage nodes, and the decision points about why it may make sense to use the acceleration card. This offers flexibility to customers who may want to select entry level CPUs to keep costs in control.
  • 23:30 Thanks and Conclusion

EP22 – Excelero – NVMe Software-Defined Storage on Steroids – with Josh Goldenhar



In this 22nd episode of the TECHunplugged Podcast we welcome Josh Goldenhar, VP of Products at Excelero. Prior to joining Excelero, Josh was responsible for product strategy and management at EMC (XtremIO) and DataDirect Networks.

Podcast co-hosts Max Mortillaro (@darkkavenger) and Arjan Timmerman (@Arjantim) talk with Josh about Excelero, the solution’s architecture, its use cases & differentiators.

Show schedule:

  • 00:00 Presentations & introduction to Excelero
  • 01:50 We learn that Excelero is software-based and uses NVMe drives. We ask Josh about whether there is a Hardware Compatibility List. Josh goes on to talk about custom built vs. co-engineered solutions (Dell, SuperMicro) and mentions a recently announced partnership with Lenovo.
  • 03:25 Josh explains how Excelero was built from the start to be hardware agnostic and provides a perspective about how each hardware vendor is looked at based on their own hardware specificities.
  • 04:46 Consuming Excelero: what customers need to do to get their Excelero storage up and running: either via pre-built appliances or via custom built hardware with installation of a couple RPM packages.
  • 06:40 Is Excelero block-based or file-based? Josh explains that Excelero is a block-based distributed storage and provides background about the rationale to go block-based only.
  • 08:40 We ask Josh about Excelero’s customers and their use cases. Low latency, consistency in response times, and ability to scale are key to those customers. Josh then goes on to explain some of the common challenges faced by web-scalers and how Excelero fits in the picture.
  • 11:25 The case of Technicolor, an Excelero customer – how the motion picture industry requires bandwidths akin to those used in HPC clusters
  • 12:35 Excelero storage deployment modes (disaggregated vs. converged) and their technical implications
  • 15:35 A look into network interconnects that are supported by Excelero and throughput capabilities
  • 19:20 Talking about HPC and Local Burst Buffer / Local Scratch – integration with SLURM job scheduler and local nodes
  • 23:50 Being mind blown and forgetting a question – the Venn Diagram of Happy and Sad
  • 24:20 Remembering a question – does Excelero supports different media / performance tiers (such as SATA SSD or HDD), or 3D XPoint. Josh provides a comprehensive view of what is supported backed by Excelero’s rationale about why things are being done or implemented in a specific way.
  • 27:30 How / where to purchase Excelero, and how is it licensed?
  • 30:15 Conclusion

EP20 – Dell Technologies Netherlands – DataCenter Technology



During this podcast our host Arjan Timmerman talks with Tom van Peer who is the Enterprise Presales lead at Dell Technologies in the Netherlands. As the conversation is on the Datacenter technology that is provided by Dell Technologies, and thus focuses on things like Dell, EMC, VMware, Pivotal and other products in the Dell Technologies portofolio.

With Tom being someone that started his career at Philips, working on AI many years ago, we also focus on the AI trends that Tom sees these days, and what that means for a company like Dell Technologies. Also we talk about two upcoming events. One the Netherlands where Tom will talk about AI and also is focused around AI. You can find the (free) registration link below:

EP 19 – TECHunplugged preview of Dell Technologies World 2019



In this episode TECHunplugged hosts Max Mortillaro and Arjan Timmerman will do a preview on Dell Technologies World 2019 which they will both attend as analysts.

The conversation is on what we think about Dell Technologies, the past but also the road ahead for this great company. The companies under the Dell Technologies umbrella offer a great opportunity but need the right guidance and steering to act as one. Also Max takes us back to the Dell Technologies analyst event in Chicago late 2018 where he heard directly from Michael Dell and his team on the Dell Technologies vision.

We also talk about the opportunity we get to be at Tech Field Day Extra at Dell Technologies World 2019, and the awesomeness and opportunities provided by the Tech Field Day Team, which by the way celebrates its ten year anniversary (congrats team!!). Looking at their website we talk a little about the #TFDx sponsor Liqid and the composable infrastructure.

Last but not least we go into what we look forward on hearing at the event, as well as some of the #DTW sponsors like Komprise (listen to our podcast with them here) and Data Management and where we would like to see (and hear) Dell Technologies focus on the next couple of years.

Happy listening!
