Remote Persistent Memory: It Takes a Village (or Perhaps a City)

By Paul Grun, Chair, OpenFabrics Alliance and Senior Technologist, Cray, Inc. Remote Persistent Memory, (RPM), is rapidly emerging as an important new technology. But understanding a new technology, and grasping its significance, requires engagement across a wide range of industry organizations, companies, and individuals. It takes a village, as they say. Technologies that are capable of bending the arc of server architecture come along only rarely. It’s sometimes hard to see one coming because it can be tough to discern between a shiny new thing, an insignificant evolution in a minor technology, and a serious contender for the Technical Disrupter of the Year award. Remote Persistent Memory is one such technology, the ultimate impact of which is only now coming into view. Read More

RoCE vs. iWARP – The Next “Great Storage Debate”

By now, we hope you’ve had a chance to watch one of the webcasts from the SNIA Ethernet Storage Forum’s “Great Storage Debate” webcast series. To date, our experts have had friendly, vendor-neutral debates on File vs. Block vs. Object Storage, Fibre Channel vs. iSCSI, and FCoE vs. iSCSI vs. iSER. The goal of this series is not to have a winner emerge, but rather educate the attendees on how the technologies work, advantages of each, and common use cases. Our next great storage debate will be on August 22, 2018 where our experts will debate RoCE vs. iWARP. They will discuss these two commonly known RDMA protocols that run over Ethernet: RDMA over Converged Ethernet (RoCE) and the IETF-standard iWARP. Both are Ethernet-based RDMA technologies that can increase networking performance. Both reduce the amount of CPU overhead in transferring data among servers and storage systems to support network-intensive applications, like networked storage or clustered computing. Read More

Dive Into SDC – A Chat with SNIA Technical Council Co-Chair Mark Carlson on Persistent Memory

The SNIA Storage Developer Conference (SDC) is coming up September 24-27, 2018 at the Hyatt Regency Santa Clara CA.  The agenda is now live!

SNIA on Storage is ready to dive into major themes of the 2018 conference, starting with Persistent Memory.   The SNIA Technical Council takes a leadership role to develop the content for each SDC, so SNIA on Storage spoke with Mark Carlson, SNIA Technical Council Co-Chair and Principal Engineer, Industry Standards, Toshiba Memory America, to understand why SDC is bringing Persistent Memory to conference attendees.

SNIA on Storage (SOS) – Why has the Technical Council chosen Persistent Memory as a major topic for 2018?

Mark Carlson (MC) – For a number of years, SNIA has been a key contributor to industry activities driving system memory and storage into a single Persistent Memory entity.  For Developers just being introduced to this new technology, SNIA has a multitude of educational resources that can be used to come up to speed on Persistent Memory and make the most of their time at SDC 2018.

SOS – Where should attendees begin? Read More

A Q&A from the FCoE vs. iSCSI vs. iSER Debate

It’s become quite clear to those of us in the SNIA Ethernet Storage Forum (ESF) that everyone loves a great debate. We’ve proved that with our “Great Storage Debates” webcast series which has had over 3,500 views in just a few months! Last month we had another friendly debate on FCoE vs. iSCSI vs. iSER. If you missed the live event, you can watch it now on-demand. Our live audience asked a lot of interesting questions. As promised, here are answers to them all. Q. How often are iSCSI offload adapters used in customer environments as compared to software initiators?  Can these adapters be used for all IP traffic or do they only run iSCSI? Read More

Simplifying the Movement of Data from Cloud to Cloud

We are increasingly living in a multi-cloud world, with potentially multiple private, public and hybrid cloud implementations supporting a single enterprise. Organizations want to leverage the agility of public cloud resources to run existing workloads without having to re-plumb or re-architect them and their processes. In many cases, applications and data have been moved individually to the public cloud. Over time, some applications and data might need to be moved back on premises, or moved partially or entirely, from one cloud to another. That means simplifying the movement of data from cloud to cloud. Data movement and data liberation – the seamless transfer of data from one cloud to another – has become a major requirement.

Accelerating the Adoption of Next-Generation Storage Technologies

Introduction to the Storage Networking Industry Association

The Storage Networking Industry Association (SNIA) is the largest storage industry association in existence, and one of the largest in IT. It is comprised of over 170 leading industry organizations, and 2,500 contributing members that serve more than 50,000 IT and storage professionals worldwide.

During the nineties, the nascent storage networking field needed a strong voice to communicate the value of storage area networks (SANs) and the Fibre Channel (FC) protocol. SNIA emerged in 1997 when a handful of storage experts realized that there was a need for a unified voice and vendor-neutral education on these emerging technologies to ensure that storage networks became feature complete, interoperable and trusted solutions across the IT landscape.

Since then, SNIA has earned a reputation for developing technologies that have emerged as industry standards. There standards relate to data, storage and information management, and address such challenges as interoperability, usability, complexity and security. Read More

Storage Controllers – Your Questions Answered

The term controller is used constantly, but often has very different meanings. When you have a controller that manages hardware, there are very different requirements than a controller that manages an entire system-wide control plane. You can even have controllers managing other controllers. It can all get pretty confusing very quickly. That’s why the SNIA Ethernet Storage Forum (ESF) hosted our 9th “Too Proud to Ask” webcast. This time it was “Everything You Wanted to Know about Storage but were Too Proud to Ask: Part Aqua – Storage Controllers.” Our experts from Microsemi, Cavium, Mellanox and Cisco did a great job explaining the differences between the many types of controllers, but of course there were still questions. Here are answers to all that we received during the live event which you can now view on-demandRead More

Security GDPR, SNIA and You

In April 2016, the European Union (EU) approved a new law called the General Data Protection Regulation (GDPR). This coming May 25th, however, is the start of enforcement, meaning that any out-of-compliance organization that does business in the EU could face large fines. Some companies are choosing to not conduct business in the EU as a result, including email services and online games.

The GDPR is applicable to any information classified as personal or that can be used to determine your identity, including your name, photo, email address, social media post, personal medical information, IP addresses, bank details and more. Read More

File, Block and Object Storage: Real-world Questions, Expert Answers

More than 1,200 people have already watched our Ethernet Storage Forum (ESF) Great Storage Debate webcast “File vs. Block vs. Object Storage.” If you haven’t seen it yet, it’s available on demand. This great debate generated many interesting questions. As promised, our experts have answered them all here. Q. What about the encryption technologies on file storage? Do they exist, and how do they affect the performance compared to unencrypted storage? Read More

FCoE vs. iSCSI vs. iSER: Get Ready for Another Great Storage Debate

As a follow up our first two hugely successful “Great Storage Debate” webcasts, Fibre Channel vs. iSCSI and File vs. Block vs. Object Storage, the SNIA Ethernet Storage Forum will be presenting another great storage debate on June 21, 2018. This time we’ll take on FCoE vs. iSCSI vs. iSER. For those of you who’ve seen these webcasts, you know that the goal of these debates is not to have a winner emerge, but rather provide unbiased education on the capabilities and use cases of these technologies so that attendees can become more informed and make educated decisions. Here’s what you can expect from this session: Read More
