#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 …

#105 – Introduction to VAST Data (Part I) with Howard Marks (Sponsored)

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

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 …

#98 – Shared Storage for Scale-out Databases with Walt Hinton from Pavilion Data

#98 – Shared Storage for Scale-out Databases with Walt Hinton from Pavilion Data

Chris EvansGuest Speakers, Storage Unpacked Podcast

In this third recording from Dell Technologies World 2019, Chris talks with Walt Hinton, Head of Corporate and Product Marketing at Pavilion Data Systems.  The topic of conversation is the alignment of shared storage with scale-out NoSQL databases that typically place storage components on separate local disks. As rack-scale computing becomes more widely adopted, local storage will migrate back into bottom-of-rack shared storage infrastructure.  In this instance, does it make sense to put shards of databases back on the same hardware?  Walt thinks it is the next logical step in optimising scale-out applications and introducing …

#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

#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

#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 …

#81 – Storage or Data Asset Management?

#81 – Storage or Data Asset Management?

Chris EvansData Management, Garbage Collection, Storage Unpacked Podcast

This week Chris and Martin talk about the evolution from storage management to data management.  This follows from recent vendor events where data management featured highly, but still seemed to focus on infrastructure products.  Is there a definition that can bridge the gap – something like Data Asset Management? The team start by trying to get a handle on what storage and data management actually mean.  In the data protection world, for example, DLP – data leakage prevention, or data loss prevention refer to more advanced versions of simple backup.  Things get more complex when …

#76 – Fibre Channel and NVMe with Mark Jones

Chris EvansGuest Speakers, Storage Unpacked Podcast

In this week’s podcast, Chris and Martin talk to Mark Jones from the Fibre Channel Industry Association.  This recording is an introduction to running NVMe over Fibre Channel, setting the scene on how Fibre Channel has evolved and will continue to be a storage protocol for many years. Fibre Channel reached an important milestone in 2018.  It’s been 30 years since development and 25 years since the first products were shipped.  Speeds started at 133Mb/s, while today, Gen 6 FC runs at 32Gb/s.  Higher speeds are coming in 2019 and can also be achieved with …
