Marketing Beschreibung

HPE Slingshot is a modern high-performance interconnect for HPC and AI clusters that delivers industry leading performance, bandwidth, and low latency for HPC, AI/ML, and data analytics applications. HPE Slingshot brings together the best of HPC optimized fabrics - as pioneered by Cray over 8 generations of supercomputing interconnect silicon - with the ubiquity of standard Ethernet. This ensures HPC clusters can deliver a converged infrastructure with great performance on both traditional modeling and simulation codes alongside native sockets-based applications, and with direct Ethernet connectivity to storage without requiring gateway nodes.
Beyond raw speed (25.6 Tbps of bidirectional bandwidth in each switch), HPE Slingshot dramatically controls loaded latency, the true determinant of realized performance on tightly coupled HPC and AI workloads. Innovative congestion management reduces run-to-run execution time variability, and fine-grained adaptive routing ensures high utilization of the bandwidth available.
With HPE Slingshot for HPC Clusters, the same interconnect in the world's most powerful supercomputers can now be deployed across a wide spectrum of HPC system sizes and configurations based on HPE Apollo and HPE ProLiant compute nodes.

Produktfeatures

• High bandwidth and low latency
  HPE Slingshot switches provide 25.6 Tbps of bi-directional bandwidth with 64 ports each capable of 200 Gbps, delivering high bandwidth and low latency simultaneously, overcoming traditional Ethernet approaches to buffering and error handling that create queueing latency that hinder low-latency RDMA applications.
• Automatic congestion management
  The HPE Slingshot network uniquely addresses the congestion challenges of short-lived, small packet flows typical in HPC applications. In hardware, each switch detects congestion, identifies its causes, and provides real-time feedback to its peers. The system distinguishes perpetrators from victims of injection and limits the injection rate from the perpetrator until congestion clears.
• Fine-grained adaptive routing
  HPE Slingshot tracks real-time information on load across each switch-to-switch path, and dynamically re-routes traffic to balance load (rather than sticking only to a predetermined path) to improve network performance and bandwidth utilization. Uniquely, HPE Slingshot's adaptive routing decisions are made on a packet-by-packet basis for unordered traffic, or a flow-by-flow basis for protocols (like TCP/IP) requiring ordered delivery.
• Quality of service
  HPE Slingshot supports highly configurable quality-of-service (QoS) that provide the ability to control how network bandwidth is allocated to different classes of traffic and applications.
• Low-diameter network
  The high-radix 64 port HPE Slingshot switches enable low-diameter topologies to reduce the quantity of network equipment, cabling, power and cooling costs. The initial topology offered is a 3-hop dragonfly topology based on a mesh of all-to-all that further reduces latency and improves sustained bandwidth and reliability. Fine-grained adaptive routing and congestion management virtually eliminate any locality concerns related to job placement and storage-connectivity in the topology.
• Ethernet standards
  The HPE Slingshot system interconnect implements a full range of Ethernet standards, with hardware support focusing on the data movement protocols, IPv4 and IPv6 in particular. Through network function virtualization functionality executing running on the fabric controller, new higher layer protocols can be added through software.
