Chris EvansAll-Flash, Guest Speakers, NVMe, Storage Hardware

Today, Hitachi Vantara announced the VSP E990, a midrange all-NVMe storage appliance. The new solution, available immediately, offers up to 5.8 million IOPS, I/O latency as low as 64µs with up to 64PB effective capacity. In this episode, Chris Evans chats remotely to Colin Gallagher about the new platform. VSP E990 extends the existing solutions in the VSP family, from the F350 up to the 5000 series enterprise-class solutions. The “E” denotes NVMe – other platform models have “F” (flash) and “G” (general) designations. The quoted 64µs latency figure is lower than the VSP 5000 …

#133 – FlashArray//C Deeper Dive with Pete Kirkpatrick

Chris EvansAll-Flash, Guest Speakers, Pure Storage

This episode was recorded live at Pure Storage offices in Silicon Valley. Chris talks to Pete Kirkpatrick, Chief Hardware Architect at Pure Storage about the FlashArray//C platform. FlashArray//C is a new solution announced at Pure Accelerate 2019 that offers a lower-cost all-flash solution for less latency-sensitive workloads. FlashArray//C uses QLC technology, a cheaper, but slower flash alternative to SLC, MLC or even TLC that is being used in all-flash arrays today. Developing a solution using QLC requires more flash management, however using DirectFlash compared to standard SSDs offers Pure Storage cost and management advantages. How …

#130 – Making Money in the Storage Business

Chris EvansAll-Flash, Garbage Collection, NVMe, Storage Hardware

This week, Chris and Martin reflect on changes in the storage industry and the ways in which vendors can make money from storage hardware and software. It’s been a tough time for storage vendors of late and the discussion starts by looking at the challenges of making money in a market where components are commodity and decline in price each month. How should vendors adapt to these challenges? There are alternative strategies than simply piling it high and selling it cheap (although that is one model). All-flash systems offered the ability to charge higher margins, …

#113 – The Expanding Storage Hierarchy with Erik Kaulberg

Chris EvansAll-Flash, Guest Speakers, Storage Hardware

This week’s episode is the first in a series from Flash Memory Summit 2019. Chris catches up with Erik Kaulberg from INFINIDAT to discuss how the expanding hierarchy of solid-state storage media will drive new products and solutions in the future. The topics of conversation cover how media has diversified, with new solutions like MRAM and 3D-XPoint. At the same time, we hear that 5-level NAND could be a reality. How are vendors combining these products with traditional storage? Will the ability to learn from the field with the deployment of traditional storage designs, provide …

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 …

#102 – May Midrange Madness with Chris Mellor

Chris EvansAll-Flash, Garbage Collection

This week Martin, Chris Evans and Chris Mellor discuss Dell EMC’s plans for merging the three current midrange storage platforms marketed by the company.  This is a follow-up to the article Chris recently posted on https://blockandfiles.com that discusses Project Trident. There are a lot of moving parts to consider when merging storage platforms.  Customers have spent time and effort developing processes and scripting to automate common processes.  How will these be supported?  Will the new platform appear to take on the persona of the previous three?  Should customers (as Martin believes) be forced to make …

#79 – Learning More About QLC Storage with Steve Hanna

Chris EvansAll-Flash, Guest Speakers

This week Chris and Martin talk to Steve Hanna, Senior Product Manager for Enterprise SSDs at Micron.  Steve looks after the 5210 ION QLC SSD product line, which was introduced earlier this year.  As an evolution of existing flash technology, QLC offers greater capacities at lower cost.  But what are the issues? The conversation covers how QLC has reduced the price to 1/100th of that seen in early enterprise SSDs.  Although endurance is lower than previous flash generations, in reality for many use cases the ability to write up to 1 DWPD is enough.  However, …
