What’s New in Computational Storage? A Conversation with SNIA Leadership

SNIAOnStorage
The latest revisions of the SNIA Computational Storage Architecture and Programming Model Version 0.8 Revision 0 and the Computational Storage API v0.5 rev 0 are now live on the SNIA website. Interested to know what has been added to the specifications, SNIAOnStorage met “virtually” with Jason Molgaard, Co-Chair of the SNIA Computational Storage Technical Work Group, and Bill Martin, Co-Chair of the SNIA Technical Council and editor of the specifications, to get the details. Both SNIA volunteer leaders stressed that they welcome ideas about the specifications and invite industry colleagues to join them in continuing to define computational storage standards.  The two documents are working documents – continually being refined and enhanced. If you are not a SNIA member, you can submit public comments via the SNIA Feedback Portal. To learn if your company is a SNIA member, check the SNIA membership list.

The Computational Storage Technical Work Group chairs also welcome your emails.  Reach out to them at computationaltwg-chair@snia.org. Read More

What is eBPF, and Why Does it Matter for Computational Storage?

SNIAOnStorage
Recently, a question came up in the SNIA Computational Storage Special Interest Group on new developments in a technology called eBPF and how they might relate to computational storage. To learn more, SNIA on Storage sat down with Eli Tiomkin, SNIA CS SIG Chair with NGD Systems; Matias Bjørling of Western Digital; Jim Harris of Intel; Dave Landsman of Western Digital; and Oscar Pinto of Samsung. SNIA On Storage (SOS):  The eBPF.io website defines eBPF, extended Berkeley Packet Filter, as a revolutionary technology that can run sandboxed programs in the Linux kernel without changing kernel source code or loading kernel modules. Why is it important? Dave Landsman (DL): eBPF emerged in Linux as a way to do network filtering, and enables the Linux kernel to be programmed.  Intelligence and features can be added to existing layers, and there is no need to add additional layers of complexity. SNIA On Storage (SOS):  What are the elements of eBPF that would be key to computational storage?  Read More

Q&A on Data Movement and Computational Storage

SNIA CMSI
Recently, the SNIA Compute, Memory, and Storage Initiative hosted a live webcast “Data Movement and Computational Storage”, moderated by Jim Fister of The Decision Place with Nidish Kamath of KIOXIA, David McIntyre of Samsung, and Eli Tiomkin of NGD Systems as panelists. We had a great discussion on new ways to look at storage, flexible computer systems, and how to put on your security hat. During our conversation, we answered audience questions, and raised a few of our own!  Check out some of the back-and-forth, and tune in to the entire video for customer use cases and thoughts for the future.

Dive – or Dip – into SNIA Persistent Memory + Computational Storage Summit Content

Marty Foltyn
SNIA’s 9th annual Summit was a success with a new name and an expanded focus – Persistent Memory + Computational Storage – from the data center to the edge. The Summit moved to a two-day virtual platform and drew twice as many attendees as the previous year. We experimented with 20-minute sessions to great success.  Attendees saw leading technology experts discussing real world applications and use cases, providing insights on technology trends and futures, and networking  in “live via the internet” panels and Birds-of-a-Feather sessions. The recap of our 2021 event – agenda – abstracts – speaker bios – links to videos and presentations – is summarized on the PM+CS Summit home page. But we know your time is precious – so here are a few ways to sample a lot of great content presented over two full days. Read More

Continuing to Refine and Define Computational Storage

SNIAOnStorage
The SNIA Computational Storage Technical Work Group (TWG) has been hard at work on the SNIA Technical Document Computational Storage Architecture and Programming Model.  SNIAOnStorage recently sat down via zoom with the document editor Bill Martin of Samsung and TWG Co-Chairs Jason Molgaard of Arm and Scott Shadley of NGD Systems to understand the work included in the model and why definitions of computational storage are so important. SNIAOnStorage (SOS): Shall we start with the fundamentals?  Just what is the Computational Storage Architecture and Programming Model? Scott Shadley (SS): The SNIA Computational Storage Architecture and Programming Model (Model) introduces the framework of how to use a new tool to architect your infrastructure by deploying compute resources in the storage layer. Bill Martin (BM): The Model enables architecture and programming of computational storage devices. These kinds of devices include those with storage physically attached, and also those with storage not physically attached but considered computational because the devices are associated with storage. SOS: How did the TWG approach creating the Model and what does it cover? Read More

Computational Storage in the Real World

Eli Tiomkin
Computational storage has arrived, with real world applications meeting the goal of enabling parallel computation and/or alleviating constraints on existing compute, memory, storage, and I/O.  The SNIA Computational Storage Special Interest Group has gathered examples of computational storage use cases which demonstrate improvements in application performance and infrastructure efficiency through the integration of compute resources either directly with storage or between the host and the storage. First up in the SNIA Computational Storage Demo Series are our SIG member companies Eideticom Communications and NGD Systems. Read More

Reflections on Computational Storage

SNIAOnStorage Leave a comment

As a year we will never forget drew to a close, SNIA on Storage sat down (virtually of course!) with Computational Storage Technical Work Group Co-Chairs Jason Molgaard of Arm and Scott Shadley of NGD Systems and Computational Storage Special Interest Group Chair Eli Tiomkin of NGD Systems to take the pulse of 2020 and anticipate 2021 computational storage advances.

SNIA On Storage (SOS): Jason, Scott, and Eli, thanks for taking the time to chat. Where was computational storage 12 months ago and how did it progress in 2020?

Compute Everywhere – Your Questions Answered

Jim Fister
Recently, the SNIA Compute, Memory, and Storage Initiative (CMSI) hosted a wide-ranging discussion on the “compute everywhere” continuum.  The panel featured Chipalo Street from Microsoft, Steve Adams from Intel, and Eli Tiomkin from NGD Systems representing both the start-up environment and the SNIA Computational Storage Special Interest Group. We appreciate the many questions asked during the webcast and are pleased to answer them in this Q&A blog. Read More

Composable or Computational – Your Questions Answered!

Eli Tiomkin
Our recent webcast on Composable Infrastructure and Computational Storage raised some interesting questions. No need to compose your own answers – my co-presenter Philip Kufeldt and I answer them here! You can find the entire webcast video along with the slide PDF in the SNIA Educational Library. We also invite you and your colleagues to take 10 and watch three short videos on Computational Storage topics. Q (I’m) a little confused about moving data across, for example, NVMe-oF, as it consumes DDR bandwidth. Can you elaborate? Read More
