#215 – Stateless Compute Machines

Chris EvansGarbage Collection, NVMe, SmartNICs, Storage Hardware, Storage Unpacked Podcast

In this week’s episode, Chris and Martin discuss network booting and the ability to create completely stateless servers. The idea of SAN booting has been around for two decades, enabling both the operating system disk and data disks to be delivered from SAN storage. NVMe/TCP and other NVMe-oF protocols promise the ability to implement the same capability for modern systems. Can this be done today? Why are more servers not booted from SAN? Is this a technical issue or one of practicality and comfort? With large-scale computing platforms, perhaps network booting will make (or already …

#214 – Can CloudFlare R2 Disrupt AWS S3?

Chris EvansAWS, Cloud, CloudFlare, Garbage Collection, Object Storage, Storage Unpacked Podcast

This week, Chris and Martin discuss the announcement from CloudFlare of R2, a new object storage solution. With such a widely dispersed CDN network, could CloudFlare become a real competitor for S3, considering that the R2 platform will have no egress fees? This episode digs into the details, to look at what additional features object storage vendors need in their arsenal and whether there’s any other vendor likely to come close to competing with AWS. At the outset of the podcast, Chris mentions Dark Star, which did indeed have a tiny budget of only $60,000. …

#213 – Kubernetes-Native Data Protection

Chris EvansData Management, Data Protection, Garbage Collection, Storage Unpacked Podcast

With KubeCon North America 2021 looming, Chris and Martin spend this week looking at data protection for Kubernetes-native environments. Vendors have started to introduce backup solutions, some working within the container environment itself, some outside as part of existing products. Exactly what should be backed up and how should these products work? Are we right to continue using snapshots or is there a better way? Do these solutions capture and retain enough metadata to provide for efficient data recovery? Lots of questions to ask and be answered in this show. Elapsed Time: 00:39:00 Timeline Related …

#212 – File Not Found

Chris EvansData Management, Garbage Collection, Storage Unpacked Podcast

In this week’s podcast, Chris and Martin get together to discuss the curious case of missing files. In this instance, the files weren’t actually missing, but according to an article in The Verge, students running a software simulation didn’t know how to determine their location. In a world where the current generation have grown up on iPhones and iPads (or similar devices) that present no inherent file and directory structure, is it any surprise that these concepts seem alien? What benefit is there to retaining strict and rigid file system structures and can we move …

#210 – Building SANs in the Cloud

Chris EvansCloud, Software-Defined Storage, Storage Unpacked Podcast

This week, Chris and Martin discuss the merits of building virtual SANs in the public cloud. Vendors including Silk and Pure Storage now offer virtual storage “appliances” built from virtual instances and cloud storage. Why are these solutions necessary, when the public cloud providers have plenty of high-performance block and file storage offerings? The discussion looks at the why and how of these types of solutions as well as the implications and the lock-in they could represent. Elapsed Time: 00:33:53 Timeline 00:00:00 – Intros 00:04:00 – Silk and Pure Storage are two examples of cloud …

#208 – NVIDIA GPUDirect Storage – More Than a Good Marketing Message?

Chris EvansGarbage Collection, NVIDIA, Storage Unpacked Podcast

In this week’s podcast, Chris and Martin look at NVIDIA’s GPUDirect Storage (GDS), a technology for moving data directly from persistent storage to GPUs, bypassing the CPU. The aim of the technology is to provide greater throughput to keep GPUs active, and looking at some of the thoughts from our podcast with Liqid (#204), it’s clear that this feature is needed. However, with such quick adoption by many storage vendors, is the announcement of GDS more of a marketing exercise? We dig into the details and what the announcement of GDS could mean for the …

#207 – AWS Gets a SAN Upgrade

Chris EvansCloud, Storage Unpacked Podcast

This week the team is back after a short break and ready to talk all things cloud – or at least about Elastic Block Store. AWS recently announced io2 and io2 Block Express, the first new EBS block storage offerings for eight years. With such a long gap since io1 was first released, what has AWS been up to and what’s new? In this discussion, Martin and Chris question whether AWS is aiming to meet the requirements of enterprise customers that simply want to lift and shift their infrastructure into the cloud. Alternatively, the effort …

#206 – An Update on NVMe 2.0 with Amber Huffman

Chris EvansGuest Speakers, NVMe, Storage Unpacked Podcast

This week, Chris and Martin chat to Amber Huffman, Intel Fellow and President of NVM Express about the updates in NVMe 2.0. NVM Express (generally abbreviated to NVMe) is a storage protocol that was developed to overcome some of the shortcomings of traditional protocols when working with new high performance media such as NAND SSDs and Optane. The 2.0 release of the NVMe standard refactors the protocol design and also introduces new features, including Namespace Types, Zoned Namespaces, Key-Value data types, endurance group management and HDD support. Amber explains the rationale behind the restructuring and …
