RSK the Hyper convergent solution "on hot water"

2018: Release of the hyper convergent solution "on hot water"

On November 27, 2018 the group "RSK" presented the hyper convergent solution with liquid cooling in the "hot water" mode based on architecture "RSK of the Tornado" and solid-state disks Intel Optane SSD DC P4801X M.2 Series with Intel Memory Drive Technology (IMDT) and showed standard scenarios of use of these solid state drives in hyper convergent the environment for creation high-speed distributed storage systems (DWH). RSK announced also plans of support in the HPC- solutions future processors families Intel Xeon Scalable (the known Cascade Lake code-named) and modules of memory of Intel Optane DC persistent memory.

According to the developer, the hyper convergent solution of RSK allows to create a storage system "on demand" (storage-on-demand), providing performance measures and capacity at the level of 1.1 TB/with on a rack with more than 495 million input-output operations per second (IOPS, input/output operations per second). This solution gives to customers ample opportunities for flexible configuring of a storage system for work with different configurations on the basis of Intel Optane SSD and normal Intel of SSD. Use of the hyper convergent solution "RSK of the Tornado" allows to define system architecture of data storage "on the fly" after installation of the equipment, adapting a complex to different types of loadings according to preferences and the user's tasks. At the same time the concept "hyper convergence" is also meant as the fact that the topology of communications and other parameters storage systems are customized program by the components performing their continuous orchestrating (automatic placement, coordination and management of complex computer systems and services) – it provides the integrated program stack "RSK BASIS". Thus, the solution of RSK represents software-defined DWH in the hyper convergent environment.

According to the statement of the developer, the combination of Intel Optane SSD to Intel Memory Drive Technology actually integrates advantages of a solid-state disk into a memory subsystem, providing to the operating system transparent access to the hybrid memory of bigger volume allowing to use more actively big data sets and also to reduce overheads. Solid-state disks of Intel provide the high capacity, performance and energy efficiency that allows to optimize creation of the modern centers of processing with highly effective storage systems. At the same time performance on one server increases, the probability of emergence of failures is minimized and the efficiency of further scaling increases. Thanks to use of these technologies of Intel, the hyper convergent solution "RSK of the Tornado" provides to HPC-users the increased flexibility and efficiency at the expense of the given opportunity of use of high-performance memory of bigger capacity with the improved characteristics.

The hyper convergent server node "RSK of the Tornado" with direct liquid cooling in the "hot water" mode is well balanced for application in the solution of the most different computing tasks and can be a component of the storage system created "on demand" based on different file systems, for example, such as Lustre (Lustre-on-demand). The computing node "RSK of the Tornado" can include to 12 solid-state disks – Intel Optane SSD DC P4801X M.2 Series or Intel of SSD DC P4511 (NVMe, M.2), the processor of the Intel Xeon Scalable family and a server payment of Intel Server Board S2600BP. Thus, based on one node the storage system up to 24 TB with high capacity and low latency can be created. Volumes of storage will grow in process of emergence in the market of solid-state disks of more high density. The hyper convergent architecture of "RSK of the Tornado" supports the different types of high-performance storage systems based on SSD created "on demand" including creation of sections based on the Lustre file system and providing integration with different schedulers of HPC-tasks, emphasized in RSK.

In November, 2018 showed to RSK the universal hyper convergent and high density solution "RSK of the Tornado" based on a full range a component for creation of modern cluster computing systems of different scale from 100% liquid cooling in the "hot water" mode, including high-performance computing nodes based on the senior processors Intel Xeon Platinum and Intel Xeon Gold models (which are a part of the Intel Xeon Scalable family), server payments of Intel Server Board S2600BP, with the high-speed solid-state disks set on them with the NVMe interface in high density M.2 formats, including Intel Optane SSD DC P4801X Series. Is a part of the solution "RSK of the Tornado" switch Intel Omni-Path Edge Switch 100 Series from 100% liquid cooling that allows to provide high efficiency of system operation of cooling in the "hot water" mode and the lowest total cost of ownership with a system.

The solution "RSK of the Tornado" based on server Intel processors has, according to the developer, high rates of compactness and computing density (up to 153 nodes in one standard cabinet 42U), the high level of energy efficiency and also provides a possibility of stable work of computing nodes in the "hot water" mode at a temperature of coolant up to +65 °C on an input in computing nodes and switches. Work in the "hot water" mode allows to apply the year-round free cooling (24x365) mode to this solution, using only dry water-cooling towers working at an ambient air temperature up to +50 °C that, in turn, allows to get rid of chillers completely. As a result the annual average indicator of a PUE system reflecting the level of efficiency of use of the electric power makes less than 1.06, noted in RSK.

High availability, fault tolerance and ease of use of the computing systems created based on solutions of RSK for high-performance computing are also provided thanks to the advanced management system and monitoring based on the integrated program stack "RSK BASIS". This system is the open and easily expanded platform created on the basis of software open source and mikroagentny architecture. It allows to exercise control both of a data processing center in general, and its separate elements, such as: computing nodes, switches, infrastructure components, tasks and processes. All elements of a complex (computing nodes, power supplies, hydroregulation modules, etc.) have the built-in module of management that provides ample opportunities for detailed telemetry and flexible management. The construct of a cabinet allows to replace computing nodes, power supplies and hydroregulations (at the condition of application of reservation) in the mode of hot swap without interruption of operability of a complex. The majority of components of a system (such as computing nodes, power supplies, network and infrastructure components, etc.) are software-defined that allows to simplify and accelerate significantly both initial deployment, and service, and the subsequent upgrade of a system. Liquid cooling of all components provides long term of their service, the developer claims.
