Another Great Storage Debate: Hyperconverged vs. Disaggregated vs. Centralized

David McIntyre
The SNIA Networking Storage Forum’s “Great Storage Debate” webcast series is back! This time, SNIA experts will be discussing the ongoing evolution of the data center, in particular how storage is allocated and managed. There are three competing visions about how storage should be done: Hyperconverged Infrastructure (HCI), Disaggregated Storage, and Centralized Storage. Join us on May 4, 2021 for our live webcast Great Storage Debate: Hyperconverged vs. Disaggregated vs. Centralized. IT architects, storage vendors, and industry analysts argue constantly over which is the best approach and even the exact definition of each. Isn’t Hyperconverged constrained? Is Disaggregated designed only for large cloud service providers? Is Centralized storage only for legacy applications? Read More

Q&A on the Ethics of AI

Jim Fister
Earlier this month, the SNIA Cloud Storage Technologies Initiative (CSTI) hosted an intriguing discussion on the Ethics of Artificial Intelligence (AI). Our expert, Rob Enderle, Founder of The Enderle Group, and Eric Hibbard, Chair of the SNIA Security Technical Work Group, shared their experiences and insights on what it takes to keep AI ethical. If you missed the live event, it Is available on-demand along with the presentation slides at the SNIA Educational Library. As promised during the live event, our experts have provided written answers to the questions from this session, many of which we did not have time to get to. Q. The webcast cited a few areas where AI as an attacker could make a potential cyber breach worse, are there also some areas where AI as a defender could make cybersecurity or general welfare more dangerous for humans?

Continuous Delivery: Cloud Software Development on Speed

Alex McDonald
It happens with more frequency these days. Two companies merge, and the IT departments breathe a small sigh of relief as they learn that they both use the same infrastructure software, though one is on-premises and one is in the cloud. Their relief slowly dissolves, as they discover that the cloud-provisioned workers are using features in the software that have yet to be integrated into the on-prem version. Now both have to adapt and it seems that no one is happy. So, what’s the best way to get these versions in sync? A Continuous Delivery model is increasingly being adopted to get software development on a pace to keep up with business demands. The Continuous Delivery model results in a development organization that looks much like current manufacturing processes with effective workers, modern machines, and a just-in-time inventory. Even large software companies are starting to embrace this cloud delivery methodology to create a continuous stream of new revisions. Read More

STA Forum Leave a comment

Questions from SAS 201 Webinar Answered

In an effort to provide ongoing educational content to the industry, the SCSI Trade Association (STA) tackled the basics of Serial Attached SCSI (SAS) in a webinar titled “SAS 201: An Introduction to Enterprise Features,” now available on the STA YouTube channel here.

Immediately following their presentations, our experts Rick Kutcipal of Broadcom and Tim Symons of Microchip Technology held a Q&A session. In this blog, we’ve captured the questions asked and answers given to provide you with insight on the recent evolutions in SAS enterprise features including 24G SAS and what they mean to system designers.

Q1. Do you think 24G SAS will only be applicable to SSDs, and HDDs will remain at 12Gb/s?
A1. Rick: At this time, hard disk drives (HDDs) can’t take advantage of the bandwidth that’s available in 24G SAS. And right now, the technology itself is focused on the backbone and then solid-state drive (SSD) connectivity. Currently, that’s the way we see it shaping up. 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

Cloud Analytics Drives Airplanes-as-a-Service Business

Jim Fister
On-demand flying through an app sounds like something for only the rich and famous, yet the use of cloud analytics is making flexible flying a reality at start-up airline, KinectAir.  On April 7, 2021, The CTO of KinectAir, Ben Howard, will join the SNIA Cloud Storage Technologies Initiative (CSTI) for a fascinating discussion on first-hand experiences of leveraging cloud analytics methods to bring new business models to life that are competitive and profitable. And since start-up companies may not have legacy data and analytics to consider, we’ll also explore what established businesses using traditional analytics methods can learn from this use case. Join us on April 7th for our live webcast “Adapting Cloud Analytics for Practical Business Use” for views from both start-up and established companies on how to revisit the analytics decision process with a discussion on: Read More

SMI-S Storage Management Quick Start Guide Series Kicks-Off

Linda Capcara
Twenty-year SNIA veteran Mike Walker has created a series of videos titled “SMI-S Quick Start Guides” that provides developers using the SMI-S storage management specification instructions on how to find useful information in a SMI-S server using the python-based PyWBEM open source tool. “Using the PyWBEM tool, I created a set of mock SMI-S 1.8 servers which I have shared with the world on GitHub,” said Walker. “I also created a set of PDFs called ‘Quick Start Guides’ and a series of videos demonstrating some of the most recent capabilities of the SMI-S 1.8 specification. Storage equipment vendors and management software vendors seeking to address the day-to-day tasks of the IT environment can use this information to work with SMI-S 1.8.” Read More

NVMe® over Fabrics for Absolute Beginners

J Metz
A while back I write an article entitled “NVMe™ for Absolute Beginners.” It seems to have resonated with a lot of people and it appears there might be a call for doing the same thing for NVMe® over Fabrics (NVMe-oF™). This article is for absolute beginners. If you are a seasoned (or even moderately-experienced) technical person, this probably won’t be news to you. However, you are free (and encouraged!) to point people to this article who need Plain English™ to get started. A Quick Refresher Any time an application on a computer (or server, or even a consumer device like a phone) needs to talk to a storage device, there are a couple of things that you need to have. First, you need to have memory (like RAM), you need to have a CPU, and you also need to have something that can hold onto your data for the long haul (also called storage). Another thing you need to have is a way for the CPU to talk to the memory device (on one hand) and the storage device (on the other). Thing is, CPUs talk a very specific language, and historically memory could speak that language, but storage could not. For many years, things ambled along in this way. The CPU would talk natively with memory, which made it very fast but also was somewhat risky because memory was considered volatile. That is, if there was a power blip (or went out completely), any data in memory would be wiped out. Not fun. Read More

Does this Look Outdated to You?

Tom Friend
Last month, the SNIA Networking Storage Forum (NSF) took a different perspective on the storage networking technologies we cover by discussing technologies and practices that you may want to reconsider. The webcast was called “Storage Technologies & Practices Ripe for Refresh.”  I encourage you to watch it on-demand.  It was an interesting session where my colleagues Eric Hibbard, John Kim, and Alex McDonald explored security problems, aging network protocols, and NAS protocols. It was quite popular. In fact, we’re planning more in this series, so stay tuned. The audience asked us some great questions during the live event and as promised, here are our answers: Q. How can I tell if my SSH connections are secure? A. Short of doing a security scan of a server’s SSH port (typically TCP/IP port 22) it can be difficult to know if your connection is secure. In general, the following are recommended: Read More
