Scaling Management of Storage and Fabrics

Composable disaggregated infrastructures (CDI) provide a promising solution to address the provisioning and computational efficiency limitations, as well as hardware and operating costs, of integrated, siloed, systems. But how do we solve these problems in an open, standards-based way?

DMTF, SNIA, the OFA, and the CXL Consortium are working together to provide elements of the overall solution, with Redfish® and SNIA Swordfish manageability providing the standards-based interface.

The OpenFabrics Alliance (OFA) is developing an OpenFabrics Management Framework (OFMF) designed for configuring fabric interconnects and managing composable disaggregated resources in dynamic HPC infrastructures using client-friendly abstractions.

Using SNIA Swordfish™ to Manage Storage on Your Network

Consider how we charge our phones: we can plug them into a computer’s USB port, into a wall outlet using a power adapter, or into an external/portable power bank. We can even place them on top of a Qi-enabled pad for wireless charging. None of these options are complicated, but we routinely charge our phones throughout the day and, thanks to USB and standardized charging interfaces, our decision boils down to what is available and convenient.

Now consider how a storage administrator chooses to add storage capacity to a datacenter.  There are so many ways to do it:  Add one or more physical drives to a single server; add additional storage nodes to a software-defined storage cluster; add additional storage to a dedicated storage network device that provides storage to be used by other (data) servers.

These options all require consideration as to the data protection methods utilized such as RAID or Erasure Coding, and the performance expectations these entail. Complicating matters further are the many different devices and standards to choose from, including traditional spinning HDDs, SSDs, Flash memory, optical drives, and Persistent Memory.

Each storage instance can also be deployed as file, block, or object storage which can affect performance. Selection of the communication protocol such as iSCSI and FC/FCoE can limit scalability options. And finally, with some vendors adding the requirement of using their management paradigm to control these assets, it’s easy to see how these choices can be daunting.

But… it doesn’t need to be so complicated! Read More

How SNIA Swordfish™ Expanded with NVMe® and NVMe-oF™

The SNIA Swordfish™ specification and ecosystem are growing in scope to include full enablement and alignment for NVMe® and NVMe-oF client workloads and use cases. By partnering with other industry-standard organizations including DMTF®, NVM Express, and OpenFabrics Alliance (OFA), SNIA’s Scalable Storage Management Technical Work Group has updated the Swordfish bundles from version 1.2.1 and later to cover an expanding range of NVMe and NVMe-oF functionality including NVMe device management and storage fabric technology management and administration.

The Need
Large-scale computing designs are increasingly multi-node and linked together through high-speed networks. These networks may be comprised of different types of technologies, fungible, and morphing. Over time, many different types of high-performance networking devices will evolve to participate in these modern, coupled-computing platforms. New fabric management capabilities, orchestration, and automation will be required to deploy, secure, and optimally maintain these high-speed networks.

The NVMe and NVMe-oF specifications provide comprehensive management for NVMe devices at an individual level, however, when you want to manage these devices at a system or data center level, DMTF Redfish and SNIA Swordfish are the industry’s gold standards. Together, Redfish and Swordfish enable a comprehensive view across the system, data center, and enterprise, with NVMe and NVMe-oF instrumenting the device-level view. This complete approach provides a way to manage your entire environment across technologies with standards-based management, making it more cost-effective and easier to operate.

About the SMI-S Storage Management Specification

SMI-S was first approved as an ISO standard in 2002. Today, it has been implemented in over 1,350 storage products that provide access to common storage management functions and features.
During its lifetime, several versions of the SMI-S standard have been approved by ISO. The current international standard for SMI-S was based on SMI-S v1.5, which was completed in 2011, submitted for ISO approval in 2012, and formally adopted in 2014 as the latest revision of ISO/IEC 24775.

SMI-S 1.8 rev 5 was sent to ISO as an update to ISO/IEC 24775 and is expected to become an internationally recognized standard in the first half of 2021. SMI-S 1.8 rev 5 is the recommended and final version of the specification as no further updates are planned.

A SNIA Superpower: PAS submitter to ISO

SNIA’s Technical Council is one of the crown jewels of the organization. Made up of a group of acknowledged storage experts, the Technical Council oversees and manages SNIA Technical Work Groups, reviews architectures submitted by work groups, and is SNIA’s technical liaison to standards organizations.

One of the Council’s superpowers is its ISO JTC-1 designation as an ARO and a PAS submitter. What does that actually mean? It’s a very big deal!

SNIA is only one of 13 organizations worldwide that have the PAS submission capability, putting it in exclusive company. The list includes:

“Traditionally, ISO standards can only reference one another. By approving SNIA as an Approved Reference Organization (ARO), JTC1 is acknowledging SNIA’s rigorous development process and technical credibility. This allows the documents that SNIA develops to be used to underpin other ISO standards,” said Arnold Jones, Technical Council Managing Director, SNIA. “In addition, SNIA has satisfied the extensive criteria to become a Publicly Available Standard (PAS) submitter.”

ISO is an independent, international organization with a membership of 165 national standards bodies. It is the international standards organization. When a SNIA standard becomes ISO-approved, virtually every country in the world has access to it along with confidence it will work well with solutions in the marketplace.

ISO/IEC JTC 1 is a joint technical committee of ISO and the International Electrotechnical Commission (IEC). Its purpose is to develop, maintain and promote standards in the fields of information technology and Information and Communications Technology.

Specifications developed by a PAS Submitter can use a streamlined approval process within ISO, assuring that recent, advanced technology moves from industry consensus to international standard as quickly and efficiently as possible.

SNIA was reaffirmed as a PAS submitter by ISO in 2018 for another five-year term, with its status in effect until September 2023.

SMI-S Storage Management Specification

The Storage Management Initiative-Specification (SMI-S) provides a real-world example of how a PAS submission works within SNIA.

SMI-S was first approved as an ISO standard in 2002. Today, it has been implemented in over 1,350 storage products that provides access to common storage management functions and features.

During its lifetime, the SMI-S standard has been approved by ISO many times. The current international standard for SMI-S was based on SMI-S v1.5, which was completed in 2011, submitted for ISO approval in 2012, and formally adopted in 2014 as the latest revision of ISO/IEC 24775.

SMI-S 1.8 was recently sent to ISO as an update to ISO/IEC 24775. SNIA believes SMI-S 1.8 rev 5 is the very best version of the specification and should be adopted worldwide. As a PAS submission, it will become an international standard much more quickly. Published by SNIA as a standard in March, 2020, it was submitted to ISO in May and began a 90-day ballot in August. If all goes as expected, SMI-S v1.8 will be approved as ISO/IEC 24775:2020 by the end of the year – less than a year after its publication as a SNIA architecture.

Understanding the Power of SNIA’s Storage Management Initiative

By Don Deel, SNIA SMI Governing Board Chair

The SNIA Storage Management Initiative (SMI) uses many acronyms that can cause confusion. SMI? That’s the name of the Initiative! SMI-S? That’s a storage management specification. CTP? That stands for Conformance Test Program, but soon there will be two! One already exists for SMI-S and the other is being developed for SNIA Swordfish. Swordfish is a storage management specification that doesn’t have an acronym.

So other than come up with confusing acronyms, what does the SMI do? The SMI is an active group with a mission to unify the storage industry to develop and standardize interoperable storage management technologies. The SMI supports the development of storage management solutions that are based upon standard interfaces instead of proprietary interfaces. This helps lower costs, makes integration efforts easier and provides increased reliability, security and manageability. Read More

An Introduction: What is Swordfish?

Barry Kittner, Technology Initiatives Manager, Intel and SNIA Storage Management Initiative Governing Board Member

To understand Swordfish, let’s start with the basics to examine how modern data centers are managed.

A user of a PC/notebook is assumed to be in control of that PC.  What happens when there are two? Or 10? Or 1,000? Today’s modern data centers can have 100,000 computers (servers) or more! That requires the ability to be in control or “manage” them from a central location.  How does one do that?  It is done via a protocol that enables remote management; today that standard is IPMI, an acronym for Intelligent Platform Management Interface, and which has existed for 20 years.  Among issues with IPMI is that the scale of today’s data centers was not fully envisioned 20 years ago, so some of the components of IPMI cannot cover the tens of thousands of servers it is expected to manage.  The developers also did not foresee the stringent security and increased privacy requirements expected in modern data centers.
