In this talk, we'll delve into the transformative potential of selective write-grouping within software-defined storage (SDS) systems, setting it against the backdrop of the Popular Data Concentration (PDC) approach. Both strategies are compatible with Shingled Magnetic Recording (SMR) and Conventional Magnetic Recording (CMR) disks with an erasure coding. Write-grouping confines write operations to a limited subset of drives, allowing inactive drives to power down and slash energy consumption by up to 43% in SMR configurations.

Thinking of CXL® as “just a bus” does a disservice to its true value as an opportunity to virtualize system resources. NVMe Over CXL™ is an abstraction of memory resources that combines bulk storage and memory along with persistence to provide a highly efficient combined resource available over multiple APIs including NVMe, DAX, HDM, BAEBI, etc. Data center power is already at crisis levels, largely due to the inefficiency of data movement where far below 1% of data moved is actually used.

Today’s SSDs are reaching extreme capacities with some coming close to petabytes of storage capacity available to Hosts. However, the SSDs are commonly using embedded computing resources and embedded DRAM controllers to provide access to this massive quantity of storage. Some of the largest drives are leveraging an increased Indirection Unit (IU) size to extend the embedded resources of the drive.

In the age of AI and the continued growth of the cloud, data is more valuable than ever. We will discuss the substantial technical breakthroughs that have enabled HDDs to continue their capacity growth rate, and then explain the difference between the major formatting technologies, CMR vs.

AI is driving the need for more data movement between devices, boxes, and racks. This data transport requires higher bandwidths which puts strain on the interconnects as well as host and device designs. While you could tackle these problems on your own, instead come and ask questions of our expert panel from the SFF Technical Work Group to see if they can address your concerns. This will be an open Q&A where we want to hear your concerns so we can address them through industry aligned solutions.

Building Content Delivery Networks, or CDNs, requires distributed, localized collections of compute, memory and storage. CDNs are built out of groups of servers at a variety of locations with various tiers and types of caches. Modern CDN caches present a huge array of variable configurations.

With Flexible Data Placement (FDP) from NVM Express® (NVMe) finalized and increasing in ecosystem momentum, it has become clear that implementation choices are becoming a real differentiator among FDP drive configurations. Some customers leverage years of Multi-Streams deployment to migrate onto large RU sizes within a single RG. Some customers may be eager to mirror their experience with Open Channel SSDs by requesting small RGs and RU sizes. Yet another customer base might be examining FDP from a history of working with high Zone counts translating into large RUH counts.
