Jayanthi Ramakalanjiyam
Our recent SNIA Data, Networking & Storage Forum (DNSF) webinar, “AI Storage: The Critical Role of Storage in Optimizing AI Training Workloads,” was an insightful look at how AI workloads interact with storage at every stage of the AI data pipeline with a focus on data loading and checkpointing. Attendees gave this session a 5-star rating and asked a lot of wonderful questions. Our presenter, Ugur Kaynar, has answered them here. We’d love to hear your questions or feedback in the comments field. Q. Great content on File and Object Storage, Are there any use cases for Block Storage in AI infrastructure requirements? A. Today, by default, AI frameworks cannot directly access block storage, and need a file system to interact with block storage during training. Block storage provides raw storage capacity, but it lacks the structure needed to manage files and directories. Like most AI frameworks, PyTorch depends on a file system to manage and access data stored on block storage. Q. Do high speed networks make some significant enhancements to I/O and checkpointing process? Read More

Solving Cloud Object Storage Incompatibilities in a Multi-Vendor Community

Michael Hoard
The SNIA Cloud Storage Technologies Initiative (CSTI) conducted a poll early in 2024 during a live webinar “Navigating Complexities of Object Storage Compatibility,” citing 72% of organizations have encountered incompatibility issues between various object storage implementations. These results resulted in a call to action for SNIA to create an open expert community dedicated to resolving these issues and building best practices for the industry. Since then, SNIA CSTI has partnered with the SNIA Cloud Storage Technical Work Group (TWG) and successfully organized, hosted, and completed the first SNIA Cloud Object Storage Plugfest (multi-vendor interoperability testing), co-located at SNIA Developer Conference (SDC), September 2024, in Santa Clara, CA. Participating Plugfest companies included engineers from Dell, Google, Hammerspace, IBM, Microsoft, NetApp, VAST Data, and Versity Software. Three days of Plugfest testing discovered and resolved issues, and included a Birds of a Feather (BoF) session to gain consensus on next steps for the industry. Plugfest contributors are now planning two 2025 Plugfest events in Denver in April and Santa Clara in September. It’s a collaborative effort that we’ll discuss in detail on November 21, 2024 at our next live SNIA CSTI webinar, “Building a Community to Tackle Cloud Object Storage Incompatibilities.” At this webinar, we will share insights into industry best practices, explain the benefits your implementation may gain with improved compatibility, and provide an overview of how a wide range of vendors is uniting to address real customer issues, discussing: Read More

Three Truths About Hard Drives and SSDs

Jason Feist 3 Comments

An examination of the claim that flash will replace hard drives in the data center

“Hard drives will soon be a thing of the past.”

“The data center of the future is all-flash.”

Such predictions foretelling hard drives’ demise, perennially uttered by a few vocal proponents of flash-only technology, have not aged well.

Without question, flash storage is well-suited to support applications that require high-performance and speed. And flash revenue is growing, as is all-flash-array (AFA) revenue. But not at the expense of hard drives.

We are living in an era where the ubiquity of the cloud and the emergence of AI use cases have driven up the value of massive data sets. Hard drives, which today store by far the majority of the world’s exabytes (EB), are more indispensable to data center operators than ever. Industry analysts expect hard drives to be the primary beneficiary of continued EB growth, especially in enterprise and large cloud data centers—where the vast majority of the world’s data sets reside.

Ceph Q&A

Erin Farr
In a little over a month, more than 1,500 people have viewed the SNIA Cloud Storage Technologies Initiative (CSTI) live webinar, “Ceph: The Linux of Storage Today,” with SNIA experts Vincent Hsu and Tushar Gohad. If you missed it, you can watch it on-demand at the SNIA Educational Library. The live audience was extremely engaged with our presenters, asking several interesting questions. As promised, Vincent and Tushar have answered them here. Given the high level of this interest in this topic, the CSTI is planning additional sessions on Ceph. Please follow us @SNIACloud or at SNIA LinkedIn for dates. Q: How many snapshots can Ceph support per cluster? Q: Does Ceph provide Deduplication? If so, is it across objects, file and block storage?  A: There is no per-cluster limit. In the Ceph filesystem (cephfs) it is possible to create snapshots on a per-path basis, and currently the configurable default limit is 100 snapshots per path. The Ceph block storage (rbd) does not impose limits on the number of snapshots.  However, when using the native Linux kernel rbd client there is a limit of 510 snapshots per image. Read More
