New Standard Brings Certainty to the Process of Proper Eradication of Data

Eric Hibbard Leave a comment

A wide variety of data types are recorded on a range of data storage technologies, and businesses need to ensure data residing on data storage devices and media are disposed of in a way that ensures compliance through verification of data eradication.

When media are repurposed or retired from use, the stored data often must be eliminated (sanitized) to avoid potential data breaches. Depending on the storage technology, specific methods must be employed to ensure that the data is eradicated on the logical/virtual storage and media-aligned storage in a verifiable manner.

Existing published standards such as NIST SP 800-88 Revision 1 (Media Sanitization) and ISO/IEC 27040:2015 (Information technology – Security techniques – Storage security) provide guidance on sanitization, covering storage technologies from the last decade but have not kept pace with current technology or legislative requirements.  

New standard makes conformance clearer

Reaching a Computational Storage Milestone

SNIAOnStorage
Version 1.0 of the SNIA Computational Storage Architecture and Programming Model has just been released to the public at www.snia.org/csarch. The Model has received industry accolades, winning the Flash Memory Summit 2022 Best of Show Award for Most Innovative Memory Technology at their recent conference. Congratulations to all the companies and individuals who contributed large amounts of expertise and time to the creation of this Model.  SNIAOnStorage sat down with SNIA Computational Storage Technical Work Group (CS TWG) co-chairs Jason Molgaard and Scott Shadley; SNIA Computational Storage Architecture and Programming Model editor Bill Martin; and SNIA Computational Storage Special Interest Group chair David McIntyre to get their perspectives on this milestone release and next steps for SNIA. SNIAOnStorage (SOS): What is the significance of a 1.0 release for this computational storage SNIA specification? Read More

Is the Data Really Gone? A Q&A

SNIA CMSI
In our recent webcast Is the Data Really Gone? A Primer on the Sanitization of Storage Devices, our presenters Jonmichael Hands (Chia Network), Jim Hatfield (Seagate), and John Geldman (KIOXIA) took an in-depth look at exactly what sanitization is, what the standards are, and where sanitization is being practiced today.  If you missed it, you can watch on-demand their recommendations for the verification of sanitization to ensure that devices are meeting stringent requirements – and access the presentation slides at the SNIA Educational Library.  Here, in our Q&A blog, our experts answer more of your questions on data sanitization.

Computational Storage: Driving Success, Driving Standards Q and A

SNIA CMSI
Our recent SNIA Compute, Memory, and Storage Initiative (CMSI) webcast, Computational Storage – Driving Success, Driving Standards, explained the key elements of the SNIA Computational Storage Architecture and Programming Model and the SNIA Computational Storage API . If you missed the live event, you can watch on-demand and view the presentation slides. Ouraudience asked a number of questions, and Bill Martin, Editor of the Model, and Jason Molgaard, Co-Chair of the SNIA Computational Storage Technical Work Group, teamed up to answer them. What’s being done in SNIA to implement data protection (e.g. RAID) and CSDs? Can data be written/striped to CSDs in such a way that it can be computed on within the drive? Read More

Using SNIA Swordfish™ to Manage Storage on Your Network

Barry Kittner
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

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. If you are not a SNIA member, you can submit public comments via the SNIA Feedback Portal. To learn if your company is a SNIA member, check the SNIA membership list. If you are a SNIA member,  go here to join the Computational Storage Technical Work Group member work area. The Computational Storage Technical Work Group chairs also welcome your emails.  Reach out to them at computationaltwg-chair@snia.org. Read More

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

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

Linda Capcara
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. Read More
