Storage Unpacked is a technology podcast that focuses on the enterprise storage market. Chris Evans, Martin Glassborow and guests discuss technology issues with vendors and industry experts.
#195 – Fungible Data Processing Units
This week’s podcast episode continues the discussion on SmartNICs and DPUs with Fungible, a company that claims to have originally coined the term DPU. Chris and Martin talk with Pradeep Sindhu (CEO and co-founder) and Jai Menon (Chief Scientist) about Fungible’s storage cluster and host-based DPU. The Fungible architecture aims to solve the challenges of disaggregation, a topic we first looked at back in September 2017.
This discussion highlights some interesting challenges that new technology such as NVMe-oF is introducing into the data centre. As we move to a model of highly parallelised workloads, the interaction between storage and compute is back under the spotlight. Fungible is working on storage products today but claims to be able to disaggregate GPUs and in the future, potentially DRAM. Interesting times.

#194 – ScaleFlux & Computational Storage Devices
In this week’s episode, Martin and Chris discuss Computational Storage with Tong Zhang, Chief Scientist and co-founder at ScaleFlux. Computational Storage devices add value to traditional NAND by offloading data processes directly onto the storage media. ScaleFlux offers two families of CSDs, including the CSD 2000 series, which implements inline data compression to improve endurance and logical device capacity.
In this conversation, Tong covers the benefits of using CSDs as well as some of the challenges of implementation. It’s likely we will se CSDs being used for AI/Analytics pre-processing, especially in the public cloud.
More information on ScaleFlux can be found at https://www.scaleflux.com/ with further technical details of Computational Storage on the SNIA Website.

#193 – HYCU Protégé Office 365 Backup as a Service
This week, Chris and Martin are talking to a podcast repeat offender, Subbiah Sundaram, VP of Products at HYCU. HYCU has recently announced the availability of Protégé for Microsoft Office 365, delivered as SaaS or Backup as a Service (BaaS). This continues an expansion of the HYCU and Protégé backup offerings that started with Nutanix data protection and has expanded past on-premises virtualisation to encompass the public cloud and now SaaS.
The conversation covers a wide range of topics relating SaaS and data protection, including the way in which services are implemented via APIs provided by SaaS vendors. With unlimited data storage, SaaS backup offers real opportunities for data mining and analysis.
To learn more about Protégé for Office 365, follow the link to https://www.hycu.com/tryhycu/. You can find more details on the support for Office 365 in the press release – here.

#192 – Storage & Kubernetes with Nigel Poulton
This week, Chris and Martin chat to long-time friend and Kubernetes legend, Nigel Poulton. Nigel is well-known in the industry for producing training courses and books on Kubernetes, although was once a storage person in a previous life. The aim of this podcast episode is to examine how storage and Kubernetes come together. However, we start by asking Nigel to explain his pivot to containers and now the Kubernetes ecosystem.
This discussion touches on some interesting aspects of how persistent storage and Kubernetes should be managed together, which today is via the CSI (Container Storage Interface). Is this plugin a long-term solution for data mobility? We also manage to get an obligatory mainframe reference into the conversation.
Sadly we didn’t get through all of our discussion topics in this long-running episode, so Nigel will be back later in the year to continue the conversation.
You can find more on Kubernetes, over at Nigel’s Website: https://nigelpoulton.com/

#191 – CIO Pandemic Priorities
This week, Chris and Martin are in discussion with Cathy Southwick, CIO at Pure Storage. The topic of conversation is the results of a CIO survey undertaken by Pure to look back at the challenges of the coronavirus pandemic and how customers have changed their IT strategies. The discussion covers how Pure Storage has adapted to the lack of in-person site visits and adapting to remote installation and operations. Digital transformation projects have continued, while customers have adapted their priorities and goals to align with the challenges presented by COVID-19. Public cloud has been an easy target for migrations. Customers are now looking at how best to rebalance workloads between on-premises and the public cloud as companies stabilise and re-adjust to a COVID-compliant way of working.
