When data processing engines are using more and more log semantics, it’s natural to extend Zoned Namespace to provide a native log interface by introduce variable size, byte append-able, named zones. Using the newly introduced ZNSNLOG interface, not only the storage device enables less write amplification/more log write performance, but more flexible and robust naming service. Given the trends towards a compute-storage disaggregation paradigm and more capable computational storage, ZNSNLOG extension enables more opportunities for near data processing.

In DellEMC Enterprise Server/Storage Validation Organization, We perform Load testing using different workloads (Web, File, FTP, Database, Mail, etc.) on Servers to identify the performance of the Systems under heavy load. Knowing how DellEMC Enterprise Systems perform under heavy load (% CPU, % Memory, % Network, % Disk) is extremely valuable and critical. This is achieved with the help of a Load Testing Tools. Load testing tools available in market comes with its own challenges like Cost, Learning Curve and Workloads Support.

Data center architectures continue to evolve rapidly to support the ever-growing demands of emerging workloads such as artificial intelligence, machine learning and deep learning. Compute Express Link™ (CXL™) is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between the host processor and devices such as accelerators, memory buffers, and smart I/O devices.

Adopting new memory technologies such as Persistent Memory and CXL-attached Memory is a challenge for software. While libraries and frameworks (such as PMDK) can help developers build new software around emerging technology, legacy software faces a more severe challenge. At IBM Research Almaden we are exploring a new approach to managing heterogeneous memory in the context of Python. Our solution, PyMM, focuses on ease-of-use and is aimed primarily at the data science community. This talk will outline PyMM and discuss how it is being used to manage Intel Optane persistent memory.

Scientific data is commonly represented by static datasets. There is a myriad of sources for such data: snapshots of the Earth, as captured by satellites, sonars, and laser scanners; the output of simulation models; the aggregation of existing datasets, and more.

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.
