Product Description

HPE FlexFabric Manageable Layer 3 Switch

HPE FlexFabric Manageable Layer 3 Switch - 3 Layer Supported - Modular - Optical Fiber - 1U High - Rack-mountable
The HPE FlexFabric 5945 Switch Series are high-density, ultra-low-latency, and top-of-rack (ToR) switches ideally suited for deployment at the aggregation or server access layer of large enterprise data centers, the HPE 5945 is also powerful enough for deployment at the core layer of medium-sized enterprises. With the increase in virtualized applications and server-to-server traffic, customers require spine and ToR switches that can meet their throughput requirements. With the HPE 5945, data centers can now support up to 100GbE per port, allowing high performance server connectivity and the capabilities to handle virtual environments. The HPE FlexFabric 5945 Switch Series provides choices that fit your budget and IT environment by cut-through with ultra-low-latency and wire speed, offering different port density and speeds 100GbE/40GbE/25GbE/10GbE spine/ ToR connectivity.
What's new
  • High-density 100GbE/40GbE/25GbE/10GbE spine/top-of-rack (ToR) connectivity.
  • HPE FlexFabric Network Analytics solution supporting real time microburst detection.
  • VXLAN, VTEP, and OVSDB support for virtualized environments.
  • Cut-through switching with ultra-low-latency and wire speed performance.
  • IPv6 support with full Layer 2 and Layer 3 features.

High-density, Advanced, Data Center Switches with HPE FlexFabric Network Analytics
The HPE FlexFabric 5945 Switch Series enables customers to scale their server-edge 10/40/100GbE top-of-rack (ToR) deployments with high-density 48 x 10GbE (SFP or BASE-T) with 6 x 40GbE ports, 48 x 10GbE (SFP or BASE-T) with 6 x 100GbE ports, and 32 x 40GbE ports, delivered in a 1RU design.
Available with a 2-slot modular version delivering two 40GbE ports and a 4-slot modular version with four 40GbE ports.
Includes HPE FlexFabric Network Analytics, which in conjunction with the HPE IMC Virtual Application Networking Fabric Manager, delivers real time visibility of microburst network congestion which negatively impacts overall network operations and performance.
High-performance Data Center Switching
The HPE FlexFabric 5945 Switch Series delivers up to 2.56 Tbps switching capacity for demanding data center applications.
Supports up to 1904 MPPS throughput for data-intensive environments.
Low latency, under 1µs for 40GbE, delivering increased network throughput.
VXLAN support for network virtualization and overlay solutions for improved flexibility. Includes Open vSwitch Database (OVSDB) for dynamic VXLAN tunnel management.
Business Agility and Resilience with Hewlett Packard Enterprise Comware 7
The HPE FlexFabric 5945 Switch Series delivers Hewlett Packard Enterprise Intelligent Resilient Fabric (IRF) with <50 msec convergence time enabling faster application response time.
The In-Service Software Update (ISSU) enables high availability with modular updates accomplished without a reboot or power cycle, in the background.
Simplicity and Lower TCO
HPE FlexFabric 5945 Switch Series simplifies switch management by up to 88% with 9-unit Hewlett Packard Enterprise Intelligent Resilient Fabric (IRF).
No hidden costs with simple one license per switch for all operating system features.
All switch ports are active and ready to use without the need for activation licenses.
