The computational storage ecosystem is growing fast, from IP providers to system integrators. How to benefit from this promising technology : design your own device and bring your added value at the device level, or save time and select an available product? This talk will present guidelines to use computational storage technology and a review of the computational storage building blocks, including computing, non-volatile memories, interfaces, embedded software, host software and tools.

It is broadly known that in an operating system, if any file is deleted, Discard will be issued to underlying storage device. When user deletes file through Operating system, it is not physically deleted from the storage medium, as a matter of fact, this file data is marked as Invalid but remains in the unmapped address space. In another instance, when host performs over write on the previously written logical space and then this previously written memory space can be invalidated by discard operation.

Storage Area Networks (SANs) are usually used to access the most critical data of an organization, therefore ensuring their security is of paramount importance. This presentation will introduce the general SAN security threats and the methods (authentication and secure channel) to mitigate them. It will also present the authentication protocol and secure channel specifications that have been defined for NVMe-oF over IP fabrics, with special attention to the NVMe/TCP case.

NVMe/TCP has the potential to provide significant benefits in application environments ranging from the Edge to Data Center. However, to fully unlock its potential, we first need to overcome NVMe over Fabrics' discovery problem. This discovery problem, specific to IP based fabrics, can result in the need for the Host admin to configure each Host to access the appropriate NVM subsystems. In addition, any time an NVM Subsystem is added or removed, the Host admin needs to update the impacted hosts.

This session provides an overview of designing and implementing NVMe/TCP across shared storage for the enterprise. This session will cover enabling this technology in Dell PowerStore, and will be co-presented with VMware to discuss NVMe/TCP initiator support. An analysis on the benefits of NVMe/TCP will be covered, along with the ecosystem support needed to ensure enterprise readiness, simplicity and scale.

Netflix Studios produces petabytes of media content accounting for billions of media assets. These assets are managed, created, edited, encoded, and rendered by artists working on a multitude of workstation environments that run on cloud, from different parts of the globe. Artists working on a project may only need access to a subset of the assets from a large corpus. Artists may also want to work on their personal workspaces on intermediate content, and would like to keep only the final copy of their work persisted on cloud.

In file systems, large sequential writes are more beneficial than small random writes, and hence many storage systems implement a log structured file system. In the same way, the cloud favors large objects more than small objects. Cloud providers place throttling limits on PUTs and GETs, and so it takes significantly longer time to upload a bunch of small objects than a large object of the aggregate size. Moreover, there are per-PUT calls associated with uploading smaller objects. In Netflix, a lot of media assets and their relevant metadata is generated and pushed to cloud.

This presentation will outline the architectures for the top three platforms in each of these two categories, Von Neumann and Programmable Logic. Showing how vendors like NVIDIA, Pensando, Marvell, Achronix, Intel, and Xilinx have chosen to architect their solutions. We will then weigh the merits and benefits of each approach while also highlighting the performance bottlenecks. By the end of the presentation, it may be fairly clear where the industry is headed, and which solutions may eventually win out.

Storage interfaces have evolved more in the past 3 years than in the previous 20 years. In Linux, we see this happening at two different layers: (i) the user- / kernel-space I/O interface, where io_uring is bringing a low-weight, scalable I/O path; and (ii) and the host/device protocol interface, where key-values and zoned block devices are starting to emerge. Applications that want to leverage these new interfaces have to at least change their storage backends.

Cloud storage footprint is in exabytes and exponentially growing and companies pay billions of dollars to store and retrieve data. In this talk, we will cover some of the space and time optimizations, which have historically been applied to on-premise file storage, and how they would be applied to objects stored in Cloud. Deduplication and compression are techniques that have been traditionally used to reduce the amount of storage used by applications.
