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.

Deploying Confidential Computing Q&A

Michael Hoard
The third live webcast in our SNIA Cloud Storage Technologies Initiative confidential computing series focused on real-world deployments of confidential computing and included case studies and demonstrations. If you missed the live event, you can watch it on demand here. Our live audience asked some interesting questions, here are our expert presenters’ answers. Q.  What is the overhead in CPU cycles for running in a trusted enclave? A. We have been running some very large machine learning applications in secure enclaves using the latest available hardware, and seeing very close to “near-native” performance, with no more than 5% performance overhead compared to normal non-secure operations. This performance is significantly better in comparison to older versions of hardware. With new hardware, we are ready to take on bigger workloads with minimal overhead. Also, it is important to note that encryption and isolation are done in hardware at memory access speeds, so that is not where you will tend to see a performance issue. Regardless of which secure enclave hardware capability you choose, each uses a different technology to manage the barrier between secure enclaves. The important thing is to look at how often an application crosses the barrier, since that is where careful attention is needed.

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: Security of Data on NVMe-oF

John Kim
Ensuring the security of data on NVMe over Fabrics was the topic of our SNIA Networking Storage Forum (NSF) webcast “Security of Data on NVMe over Fabrics, the Armored Truck Way.” During the webcast our experts outlined industry trends, potential threats, security best practices and much more. The live audience asked several interesting questions and here are answers to them. Q. Does use of strong authentication and network encryption ensure I will be compliant with regulations such as HIPAA, GDPR, PCI, CCPA, etc.? A. Not by themselves. Proper use of strong authentication and network encryption will reduce the risk of data theft or improper data access, which can help achieve compliance with data privacy regulations. But full compliance also requires establishment of proper processes, employee training, system testing and monitoring. Compliance may also require regular reviews and audits of systems and processes plus the involvement of lawyers and compliance consultants. Q. Does using encryption on the wire such as IPsec, FC_ESP, or TLS protect against ransomware, man-in-the middle attacks, or physical theft of the storage system? Read More

Moving Genomics to the Cloud

Alex McDonald
The study of genomics in modern biology has revolutionized the discovery of medicines and the COVID pandemic response has quickened genetic research and driven the rapid development of vaccines. Genomics, however, requires a significant amount of compute power and data storage to make new discoveries possible. Making sure compute and storage are not a roadblock for genomics innovations will be the topic of discussion at the SNIA Cloud Storage Technologies Initiative live webcast “Moving Genomics to the Cloud: Compute and Storage Considerations.” This session will feature expert viewpoints from both bioinformatics and technology perspectives with a focus on some of the compute and data storage challenges for genomics workflows. We will discuss: Read More

Extending Storage to the Edge

Jim Fister
Data gravity has pulled computing to the Edge and enabled significant advances in hybrid cloud deployments. The ability to run analytics from the datacenter to the Edge, where the data is generated and lives, also creates new use cases for nearly every industry and company. However, this movement of compute to the Edge is not the only pattern to have emerged. How might other use cases impact your storage strategy? That’s the topic of our next SNIA Cloud Storage Technologies Initiative (CSTI) live webcast on August 25, 2021 “Extending Storage to the Edge – How It Should Affect Your Storage Strategy” where our experts, Erin Farr, Senior Technical Staff Member, IBM Storage CTO Innovation Team and Vincent Hsu, IBM Fellow, VP & CTO for Storage will join us for an interactive session that will cover:
  • Emerging patterns of data movement and the use cases that drive them
  • Cloud Bursting
  • Federated Learning across the Edge and Hybrid Cloud
  • Considerations for distributed cloud storage architectures to match these emerging patterns

Can you imagine a realistic scenario where the different storage types are used as storage tiers? How much are they interoperable? Read More

Accelerating Disaggregated Storage to Optimize Data-Intensive Workloads

SNIA CMSI

Thanks to big data, artificial intelligence (AI), the Internet of things (IoT), and 5G, demand for data storage continues to grow significantly. The rapid growth is causing storage and database-specific processing challenges within current storage architectures. New architectures, designed with millisecond latency, and high throughput, offer in-network and storage computational processing to offload and accelerate data-intensive workloads.

On June 29, 2021, SNIA Compute, Memory and Storage Initiative will host a lively webcast discussion on today’s storage challenges in an aggregated storage world and if a disaggregated storage model could optimize data-intensive workloads.  We’ll talk about the concept of a Data Processing Unit (DPU) and if a DPU should be combined with a storage data processor to accelerate compute-intensive functions.   We’ll also introduce the concept of key value and how it can be an enabler to solve storage problems.

Join moderator Tim Lustig, Co- Chair of the CMSI Marketing Committee, and speakers John Kim from NVIDIA and Kfir Wolfson from Pliops as we shift into overdrive to accelerate disaggregated storage. Register now for this free webcast.

The post Accelerating Disaggregated Storage to Optimize Data-Intensive Workloads first appeared on SNIA Compute, Memory and Storage Blog.

Storage Technologies & Practices Ripe for Refresh – Part 2

Alex McDonald
So much of what we discuss in SNIA is the latest emerging technologies in storage. While it’s good to know all about the latest and greatest technologies, it’s also important to understand those technologies being sunsetted. In this SNIA Networking Storage Forum (NSF) webcast series “Storage Technologies & Practices Ripe for Refresh” we cover technologies that are at (or close to) being past their useful life. On June 22, 2021, we’ll host the second installment of this series, Storage Technologies & Practices Ripe for Refresh – Part 2 where we’ll discuss obsolete hardware, protocols, interfaces and other aspects of storage. We’ll offer advice on how to replace these older technologies in production environments as well as why these changes are recommended. We’ll also cover protocols that you should consider removing from your networks, either older versions of protocols where only newer versions should be used, or protocols that have been supplanted by superior options and should be discontinued entirely. Finally, Read More
