Hacking with the U

Marty Foltyn

It’s now less than three weeks for the next SNIA Persistent Memory Hackathon and Workshop.  Our next workshop will be held in conjunction with the 10th Annual Non-Volatile Memory Workshop (http://nvmw.ucsd.edu/) at the University of California, San Diego on Sunday, March 10th from 2:00pm to 5:30pm.

The Hackathon at NVMW19 provides software developers with an understanding of the different tiers and modes of persistent memory, and gives an overview of the standard software libraries that are available to access persistent memory.  Attendees will have access to system configured with persistent memory, software libraries, and sample source code. A variety of mentors will be available to provide tutorials and guide participants in the development of code. Learn more here.

What Are the Networking Requirements for HCI?

J Metz
Hyperconverged infrastructures (also known as “HCI”) are designed to be easy to set up and manage. All you need to do is add networking. In practice, the “add networking” part has been more difficult than most anticipated. That’s why the SNIA Networking Storage Forum (NSF) hosted a live webcast “The Networking Requirements for Hyperconverged Infrastructure” where we covered what HCI is, storage characteristics of HCI, and important networking considerations. If you missed it, it’s available on-demand. We had some interesting questions during the live webcast and as we promised during the live presentation, here are answers from our expert presenters: Read More

Persistently Fun Once Again – SNIA’s 7th Persistent Memory Summit is a Wrap!

kristin.hauser
Leave it to Rob Peglar, SNIA Board Member and the MC of SNIA’s 7th annual Persistent Memory Summit to capture the Summit day as persistently fun with a metric boatload of great presentations and speakers! And indeed it was a great day, with fourteen sessions presented by 23 speakers covering the breadth of where PM is in 2019 – real world, application-focused, and supported by multiple operating systems. Find a great recap on the Forbes blog by Tom Coughlin of Coughlin Associates. Attendees enjoyed live demos of Persistent Memory technologies from AgigA Tech, Intel, SMART Modular, the SNIA Solid State Storage Initiative, and Xilinx.  Learn more about what they presented here. And for the first time as a part of the Persistent Memory Summit, SNIA hosted a Persistent Memory Programming Hackathon sponsored by Google Cloud Read More

Experts Answer Virtualization and Storage Networking Questions

J Metz
The SNIA Networking Storage Forum (NSF) kicked off the New Year with a live webcast “Virtualization and Storage Networking Best Practices.” We guessed it would be popular and boy, were we right! Nearly 1,000 people registered to attend. If you missed out, it’s available on-demand. You can also download a copy of the webcast slides. Our experts, Jason Massae from VMware and Cody Hosterman from Pure Storage, did a great job sharing insights and lessons learned on best practices on configuration, troubleshooting and optimization. Here’s the blog we promised at the live event with answers to all the questions we received. Q. What is a fan-in ratio? A. fan-in ratio (sometimes also called an “oversubscription ratio”) refers to the number of hosts links related to the links to a storage device. Using a very simple example can help understand the principle: Say you have a Fibre Channel network (the actual speed or protocol does not matter for our purposes here). You have 60 hosts, each with a 4GFC link, going through a series of switches, connected to a storage device, just like in the diagram below: Read More

The Ins and Outs of a Scale-Out File System Architecture

John Kim
To meet the increasingly higher demand on both capacity and performance in large cluster computing environments, the storage subsystem has evolved toward a modular and scalable design. The scale-out file system has emerged as one implementation of the trend, in addition to scale-out object and block storage solutions. What are the key principles when architecting a scale-out file system? Find out on February 28th when the SNIA Networking Storage Forum (NSF) hosts The Scale-Out File System Architecture Overview, a live webcast where we will present an overview of scale-out file system architectures. This presentation will provide an introduction to scale-out-file systems and cover: Read More

Wondering What’s New in Container Storage?

Alex McDonald
The landscape of containers is moving fast and constantly changing, with new standards emerging every few months. If you wondering what’s new in container storage, you are not alone. That’s why the SNIA Cloud Storage Technologies Initiative is hosting a live webcast on February 26, 2019, “What’s New in Container Storage.” In this webcast, Keith Hudgins of Docker joins us as a follow up to his earlier container webcast “Intro to Containers, Container Storage and Docker.” It’s our most popular webcast to date with thousands of views. If you missed it, it’s available on demand and will provide you with some great background information before our February 26th webcast. I encourage you to register today for the February 26th session where you’ll learn: Read More

New Capability in Familiar Places

Marty Foltyn
When it comes to persistent memory, many application developers initially think of change as hard work that likely yields incremental result.  It’s perhaps a better idea to look at the capability that’s new, but that’s already easily accessible using the methods that are in place today.  It’s not that enabling persistent memory is effortless, it’s more that normal code improvement can take advantage of the new features in the standard course of development. The concept of multiple memory tiers is ingrained in nearly every programming model.  While the matrix of possibility can get fairly complex, it’s worth looking at three variables of the memory model.  The first is the access type, either via load/store or block operation. The second is the latency or distance from the processing units; in this case the focus would be on the DIMM.  The last would be memory persistence. Read More

Extending the Reach of Storage Developer Education in 2019

khauser Leave a comment

With another successful year of SNIA Storage Developer Conferences (SDC) completed, SNIA on Storage spoke with Mark Carlson, SNIA Technical Council Co-Chair, on 2018 highlights and 2019 plans to educate and support this important technical community.

SNIA On Storage (SOS):  In 2018, SNIA volunteers provided key resources and time supporting our storage developer community, a central focus for the Technical Council.  What activities were the TC most pleased with in 2018?

Mark Carlson (MC):  For the past several years we have been pushing SDC to expand globally. Starting with SDC India and this year adding SDC EMEA, we are reaching developers around the world now with educational content. Each year we get better and better talk proposals and the hard part is not being able to present more content. I always encourage developers to submit talks on their latest discoveries and architectures. Other developers want to hear about it.

SOS:  There was a lot of good feedback on the content from SDC North America in 2018.  What was your overall impression of this 21st SDC event? Read More

Opportunity for Persistent Memory is Now

Marty Foltyn
It’s very rare that there is a significant change in computer architecture, especially one that is nearly immediately pervasive across the breadth of a market segment.  It’s even more rare when a fundamental change such as this is supported in a way that software developers can quickly adapt to existing software architecture. Most significant transitions require a ground-up rethink to achieve performance or reliability gains, and the cost-benefit analysis generally pushes a transition to the new thing be measured in multiple revisions as opposed to one, big jump. In the last decade the growth of persistent memory has bucked this trend.  The introduction of the solid-state disk made an immediate impact on existing software, especially in the server market.  Any program that relied on multiple, small-data, read/write cycles to disk recognized significant performance increases. In cases such as multi-tiered databases, the software found a, “new tier,” of storage nearly automatically and started partitioning data to it.  In an industry where innovation takes years, improvement took a matter of months to proliferate across new deployments.
