At our recent SNIA SCSI Trade Association Forum webinar, “Storage Trends 2024” our industry experts discussed new storage trends developing in the coming year, the applications and other factors driving these trends, and shared market data that illustrated the assertions. If you missed the live event, you can watch it on-demand in the SNIA Educational Library. Questions from the audience ranged from projections about the split between on-prem vs public cloud to queries about different technologies and terms such as NVMe, LTO tape, EDSFF and Cyber Storage. Here are answers to the audience’s questions.

Power Efficiency Measurement – Our Experts Make It Clear – Part 1
Measuring power efficiency in datacenter storage is a complex endeavor. A number of factors play a role in assessing individual storage devices or system-level logical storage for power efficiency. Luckily, our SNIA experts make the measuring easier!
In this SNIA Experts on Data blog series, our experts in the SNIA Solid State Storage Technical Work Group and the SNIA Green Storage Initiative explore factors to consider in power efficiency measurement, including the nature of application workloads, IO streams, and access patterns; the choice of storage products (SSDs, HDDs, cloud storage, and more); the impact of hardware and software components (host bus adapters, drivers, OS layers); and access to read and write caches, CPU and GPU usage, and DRAM utilization.
Join us on our journey to better power efficiency as we begin with Part 1: Key Issues in Power Efficiency Measurement. Bookmark this blog and check back in February, March, and April for the continuation of our four-part series. And explore the topic further in the SNIA Green Storage Knowledge Center.

Connector and Cable differences: SAS-3 vs. SAS-4
By: David Einhorn, SCSI Trade Association Board of Directors; Business Development Manager, North America, Amphenol Corp., June 14, 2022
This blog post examines the differences between SAS-3 and SAS-4 connectors and cables. With the new generation of SAS, we see multiple upgrades and improvements.
Drive connector
[Note: 24G SAS uses the SAS-4 physical layer, which operates at a baud rate of 22.5Gb/s.]
The 29-position receptacle and plug connectors used in SAS-4 feature: hot-plugging, blind-mating, connector misalignment correction, and a PCB retention mechanism for robust SMT attachment. The connectors are SATA compliant and available across many suppliers in range of vertical and right-angle configurations. Typical applications are consistent with previous generations of server and storage equipment, HDDs, HDD carriers, and SSDs.

Questions & Answers from our January 2023 Webcast: Storage Trends in 2023 and Beyond
These questions were asked and mostly answered during our webcast, Storage Trends in 2023 and Beyond. Graphics included in this article were shown during the webcast, and several of the questions refer to the data in the charts.
Thank you to our panelists:
Don Jeanette, Vice President, TRENDFOCUS
Patrick Kennedy, Principal Analyst, ServeTheHome
Rick Kutcipal, At-Large Director, SCSI Trade Association and Product Planner, Data Center Solutions Group, Broadcom
Q1: What does the future hold for U.3? (SFF-TA-1001) Was it included in the U.2 numbers?
U.2 should be U.X in the pie chart. There are some shipments out there today, customers are taking it, and it will likely grow — but all the efforts and priorities are really E3S, E1S and then, to some extent, E1,L.

24G SAS: an Overview of the Technology & Products
Hyperscale and enterprise data centers continue to grow rapidly and to use SAS products as a backbone. Why SAS, and what specific SAS products are helping these data centers to grow? This article briefly discusses the technology evolution of SAS, bringing us to our latest generation of 24G SAS. We will examine recent market data from TRENDFOCUS, underscoring the established and growing trajectory of SAS products. We will highlight our latest plugfest, which smoothed the way for 24G SAS to seamlessly enter the existing data storage ecosystem. Finally, we will help the reader to understand the availability, breadth, and depth of 24G SAS products that are available today, and where you can get those products.

Dynamic Speakers on Tap for the 2022 SNIA Persistent Memory + Computational Storage Summit
Our 10th annual Persistent Memory + Computational Storage Summit is right around the corner on May 24 and 25, 2022. We remain virtual this year, and hope this will offer you more flexibility to watch our live-streamed mainstage sessions, chat online, and catch our always popular Computational Storage birds-of-a-feather session on Tuesday afternoon without needing a plane or hotel reservation!
This year, the Summit agenda expands knowledge on computational storage and persistent memory, and also features new sessions on computational memory, Compute Express Link TM (CXL)TM, NVM Express, SNIA Smart Data Accelerator Interface (SDXI), and Universal Chiplet Interconnect Express (UCIe).

The well-attended event generated a lot of questions! So many in fact, we’re authoring a two-part blog series with the answers. In part one, we recap the questions that were asked and answered during the webcast, but since we ran out of time to answer them all, please watch for part two when we tackle the rest.
Q&A from “SAS 201: An Introduction to Enterprise Features” Webcast
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
