#114 – CIO Storage & Data Challenges with Clay Ryder

Chris EvansData Management, Guest Speakers, Storage Unpacked Podcast

This week, Chris catches up with Clay Ryder from the DCS (Data Centre Systems) group at Western Digital. The discussion focuses on the challenges for today’s CIO, with an emphasis on storage and data. The division of responsibility between CTO and CIO isn’t always obvious. As we learn in this discussion, there’s a lot of overlap and a lot of interaction between the two. CIOs are focused on data and more specifically information, whereas the CTO has to deliver the right platform to meet application needs. The conversation covers challenges around technical debt, determining what …

#106 – Introduction to VAST Data (Part II) with Howard Marks (Sponsored)

Chris EvansAll-Flash, Guest Speakers, Sponsored, Storage Unpacked Podcast

In this second episode on VAST Data, Chris and Martin continue the discussion with Howard Marks.  You can find the previous episode at #105 – Introduction to VAST Data (Part I).  This time, the conversation continues where the discussion left off, with Howard finishing the explanation of wide striping. To explain exactly how data is accessed on the platform, Howard introduces the concept of v-trees.  These are like b-trees but flatter and wider.  The v-tree is used to hold both metadata and data.  One interesting aspect of the discussion is in understanding exactly how Optane …

This week, Chris and Martin talk to Howard Marks, Chief Storyteller at VAST Data.  You may know Howard as an independent analyst and author for a range of online publications.  Howard recently joined VAST to help explain and promote understanding of their data platform architecture. The VAST Data platform uses three main technologies that have only recently emerged onto the market.  QLC NAND flash provides long-term, cheap and fast permanent storage.  3D-XPoint (branded as Intel Optane) is used to store metadata and new data before it is committed to flash.  NVMe over Fabrics provides the …

#96 – Discussing SmartNICs and Storage with Rob Davis from Mellanox

#96 – Discussing SmartNICs and Storage with Rob Davis from Mellanox

Chris EvansGuest Speakers, SmartNICs, Storage Unpacked Podcast

In this podcast, recorded live at Dell Technologies World 2019, Chris talks to Rob Davis, VP of Storage Technology at Mellanox, about the development of SmartNIC technology and storage.  SmartNICs offload tasks such as encryption, compression and protocol traffic from core CPUs.  This allows system vendors to create more efficient and cheaper products.  It can also provide a backward compatibility for legacy applications and operating systems. Rob takes us through the implementation of SmartNICs on both the initiator (host) and target (array) side of the storage network.  We discuss vendors using the technology and what …

#87 – The Risks of Storage Media Reuse versus Recycling

Chris EvansGuest Speakers, Storage Hardware, Storage Unpacked Podcast

In this episode, Chris and Martin talk to Simon Zola from Avtel Data Destruction.  This is a follow-up episode to #85 (Storage for Home and Homelabs) where Martin and Chris questioned the ease of recovering data from pre-owned storage media.  As we find out, the process was pretty easy.  Martin was able to recover significant amounts of personal data with little effort and using standard tools. Media destruction is one route to safely dispose of drives and guarantees that data is destroyed.  But what are the consequences?  Simply disabling a drive and throwing it into …

#84 – Discussing New NVMe Form Factors with Jonathan Hinkle

Chris EvansGuest Speakers, Storage Unpacked Podcast

This week, Chris and Martin talk to Jonathan Hinkle, Principal Researcher – System Architecture and Master Inventor at Lenovo.  As solid-state storage and NVMe become more prevalent, the legacy 2.5″ HDD format is increasingly impractical for getting the best density, power and cooling in servers.  Jonathan explains how his work led to the founding of the Enterprise and Data Centre Small Form Factor working group and new device formats being introduced into the industry. EDSFF is responsible for managing device standards like Intel Ruler (see a previous blog episode covering this technology).  How did the …

#55 – Storage for Hyperscalers

Chris EvansCloud, Guest Speakers, Storage Unpacked Podcast

This week we talk to Mark Carlson, co-chair of the SNIA Technical Council, about the storage needs of hyperscalers.  Mark defines hyperscalers as those companies opening multiple data centres a year, most notably Amazon, Microsoft Azure, Google and Facebook in the US and Baidu, Alibaba and Tencent in China.  These vendors are deploying petabytes of storage a year, with specific requirements on storage media.  The hyperscaler applications have issues with HDD and SSD performance characteristics, such as tail latency and the effects of garbage collection.  As a result, drive manufacturers are building in new features …

#43 – All-flash Market Review 2018 with Chris Mellor

Chris EvansGuest Speakers, Storage Unpacked Podcast

This week, Chris and Martin review the all-flash market with Chris Mellor.  We looked at this sector around 12 months ago, so we’re ready for an update.  Lots of things have happened over the past 12 months.  Vendors have gone away and come back (Violin).  Existing vendors have seen a resurgence in their sales (IBM and NetApp), while others have struggled.  Pure Storage is now an incumbent alongside the likes of Dell EMC, IBM, NetApp and HPE. The conversation moves on to discuss some interesting start-ups like WekaIO and both Excelero and E8 Storage (previous …
