We present RAINBLOCK, a public blockchain that achieves high transaction throughput without modifying the proof-of-work consensus. The chief insight behind RAINBLOCK is that while consensus controls the rate at which new blocks are added to the blockchain, the number of transactions in each block is limited by I/O bottlenecks. Public blockchains like Ethereum keep the number of transactions in each block low so that all participating servers (miners) have enough time to process a block before the next block is created.

SODA Foundation is an open source project aimed to foster an ecosystem of open source data management and storage software for data autonomy. SODA Foundation offers a neutral forum for cross-projects collaboration and integration and provides end users quality end-to-end solutions. In this talk, we would like to provide a brief overview of the foundation including our background, mission, and objective. We will introduce and demonstrate the architecture of our core projects and how they interwork with each other.

Software-Enabled Flash™ technology is being developed to allow storage developers to maximize the value of flash deployed in their data centers. It makes flash storage software-defined by redefining the relationship between the host and solid-state storage. Purpose-built, media-centric hardware focused on cloud-scale requirements, combined with an open source API and SDK, give developers tools to define latency outcomes, tenant isolation, control flash background processes, and build their own application-centric storage protocols.

Los Alamos is working to revolutionize how scientific data management is done, moving from large Petabyte sized files generated periodically by extreme scale simulations to a record and column based approach. Along the journey, the NVME Computational Storage efforts became a strategic way to help accomplish this revolution. Los Alamos has been working on a series of proof of concepts with a set of data storage industry partners and these partnerships have proven to be the key to success.

nvme-stas is an open source Linux project that provides: - A Central Discovery Controller (CDC) client for Linux - Asynchronous Event Notifications (AEN) handling - Automated NVMe subsystem connection controls - Error handling and reporting - Automatic (zeroconf) and Manual configuration nvme-stas is composed of two services, stafd and stafd, running on a Host computer. It uses the newly released libnvme 1.0 to communicate with the Linux kernel's nvme driver.

Technically, everything would be new since Apple has never given a talk about what is in our SMB Client. We will cover: 1. Multichannel implementation and how client NICs are selected and logic for handling multiple channels 2. Lease implementation current and upcoming changes in macOS Ventura 3. Upcoming changes in macOS Ventura for searching over SMB 4. Touch on dateless file support for SMB in macOS 5. Touch on Snapshot support for SMB in macOS

Today, storage and memory hierarchies are manually tuned and sized at design time. But tomorrow’s workloads are increasingly dynamic, multi-tenant and variable. It just simply is not possible to build truly autonomous storage systems that can adapt to changing application workloads with today’s methods. In this session, we demonstrate recent breakthroughs in autonomous storage systems research including how traditional real-time approaches have not been able to succeed up to now.

Zero Trust is a collection of security methodologies that work together to enforce access, with the view that your network has already been compromised, and using contextual information from identity, security, and IT infrastructure, along with risk and analytics tools, to enable dynamic enforcement of security policies uniformly across the corporate network. This session will highlight the main attributes of Zero Trust, and why it is important for storage developers.

On the domain controller side we got a lot of updates recently: - Updated Heimdal - Working with the latest MIT Kerberos On the member server side we fixed some critical bugs and have plans for future improvements how a file server can avoid as much domain controller interaction as possible.

The exponential growth in data volume and traffic across the global internet infrastructure is motivating the exploration of new architectures for data centers to achieve the demand for better performance, efficiency and total cost of ownership (TCO). One promising trend is to segregate the functional components of compute, memory, storage, and networking into pools and organize them as needed according to the specific needs of different workloads. This disaggregation and composability will take us beyond the classic architecture of servers as the unit of computing.
