#120 – NVMe 1.4 Deep Dive Part I with J Metz

Chris EvansGuest Speakers, NVMe, Storage Unpacked Podcast

This week Chris and Martin talk to J Metz, R&D Engineer in Cisco Systems’ Advanced Storage division. This is a two-parter – the second episode will be published on Monday 30th September 2019. The NVMe 1.4 specification has recently been published and is in the final 45-day ratification process. This discussion provides some background on NVMe then dives pretty deep into the NVMe standards and how design decisions are refactoring the NVMe protocol for version 2.0. NVMe for consumer devices will be different to the feature set used within enterprise storage (although the protocol is …

#115 – The Transition to NVMe-oF Storage Solutions with Praveen Asthana

#115 – The Transition to NVMe-oF Storage Solutions with Praveen Asthana

Chris EvansGuest Speakers, Storage Hardware

This week, Chris catches up with Praveen Asthana from Exten Technologies in an episode recorded at Flash Memory Summit 2019. With NVMe and NVMe over Fabrics set to become the dominant technologies for public cloud and the enterprise, exactly how will the transition from current solutions occur? Praveen discusses the continuing need for centralised storage that can fully exploit the benefits of NVMe. This will need another transition in technologies in the same way flash created a whole new market of storage solutions some ten years ago. An interesting aspect of NVMe adoption is the …

#90 – Dell EMC's Enterprise NVMe Strategy with Vince Westin (Sponsored)

Chris EvansGuest Speakers, Sponsored

This week, Chris talks to Vince Westin, Technical Evangelist within the PowerMax Group at Dell EMC.  PowerMax is the latest in a storage product line with lineage back to the original Symmetrix systems of the early 1990s.  PowerMax is an all-NVMe storage array, reflecting an industry move towards faster, low latency media.  Vince takes us through the rationale for moving to NVMe across the Dell portfolio and PowerMax in particular. Some of the more interesting aspects of the transition include the ability to simplify code paths with NVMe compared to back-end SAS.  NVMe introduces a …

#59 – Ethernet vs Fibre Channel

#59 – Ethernet vs Fibre Channel

Chris EvansGuest Speakers

This week’s podcast looks at storage networking and in particular the choice of using Ethernet vs Fibre Channel as the network protocol.  Traditionally, enterprise storage platforms have been Fibre Channel connected, with only a small amount of iSCSI usage.  However, the world isn’t just block storage and in fact, as guest Marty Lans (General Manager, Storage Connectivity Engineering & Global Interoperability Business Unit at HPE) tells us, 80% of storage is Ethernet connected.  This is because of the growth in unstructured data stored on NAS and object stores. Ethernet storage now includes lossless Ethernet (DCB) …
