H3C 7503E-M Series Enterprise Core Switches

H3C 7503E-M Series Enterprise Core Switches

The S7500E series has become one of the best-selling product series since its release nine years ago; The update of the proprietary H3C operating system from version V5 to V7 provided a new leap in popularity for the S7500E series switches thanks to the following features and advantages:

Increased bandwidth per slot and overall switch performance

10G high-density line cards

Support Multitenant Device Context (MDC), Ethernet Virtual Interconnect (EVI), VXLAN and MACsec

Intelligent fault-tolerant architecture version technology 2 (IRF2)

Convergence of MPLS, VPN and various services

Solution EVPN based on MP-BGP

These all-new series switches are ideal for enterprise network modernization and provide maximum return on investment and reduced total cost of ownership. The all-new S7500E V7 series switches include the S7503E-M and S7506E-NonPoE models.

High-Density 10G Line Card

Supports a high-density 10G (48-port) line card to meet all current and future application needs for data centers.

Virtualization technologies – IRF2

Using IRF2, you can virtualize up to four S7500E V7 switches in one logical switch fabric IRF. IRF2 has the following advantages:

High Availability (HA) – Patented hot standby technology realizes data redundancy and uninterrupted forwarding for the control plane and data plane. This improves availability and performance, eliminates critical elements that could cause system failure, and ensures uninterrupted service delivery.

Load balancing – the ability to aggregate links across different chassis provides load balancing and redundant connections across multiple backbone interfaces, which increases the degree of redundancy and channel capacity utilization.

Ease of management – management the entire IRF switch fabric is carried out through a single IP address, which simplifies device and topology management, increases operational efficiency and reduces network maintenance costs.

Virtualization technologies – MDC support

MDC technology allows a single S7500E V7 switch (excluding the S7503E-M) to be virtualized as multiple logical switches, allowing you to use a single core switch to support multiple services.

1:N virtualization maximizes switch resource utilization, reduces total network cost of ownership, and provides service isolation.

Features for data centers

Ethernet Virtual Interconnect (EVI) technology is a technology for encapsulating MAC addresses in IP packets, providing connection to Layer 2 between Layer 2 networks at remote sites using a routed IP network. It is used to combine geographically remote sites into a large virtualized data center, the nodes of which require Layer 2 proximity.

Virtual Extensible LAN technology , VXLAN) – this technology uses a method of encapsulating MAC addresses into UDP frames, in which a VXLAN header is added to the original Layer 2 packet and the resulting one is placed in a UDP-IP packet. By encapsulating MAC addresses within UDP frames, VXLAN technology allows Layer 2 network traffic to be tunneled through a Layer 3 network, providing two major benefits: greater scalability for Layer 2 segmentation and greater utilization of existing routes in the network.

MP-BGP EVPN (Multi-Protocol Edge Routing for Ethernet Virtual Private Networks) uses the standard-based BGP protocol as the control plane for VXLAN overlay networks, providing automatic discovery peers and disseminate end-host reachability information using BGP-based VTEP. MP-BGP EVPN has many advantages, such as eliminating traffic flooding, eliminating the need for a mandatory mesh network between VTEP peers by supporting BGP RR, achieving optimal flow-based end-to-end load balancing, and much more.

Full support for MPLS/VPLS functions

H3C S7500E V7 series switches support Multi-VRF functionality (multiple instances of virtual routing and forwarding tables), allowing it to be used as MCE equipment supporting MPLS VPN Layer 3 MPLS VPN Layer 2 (Martini and Kompella). In addition, the switches support OAM functionality for MPLS, simplifying management and maintenance. When used in conjunction with the H3C intelligent Management Center (iMC) network management system, MPLS VPN Manager makes it easy to deploy and maintain MPLS.

Additionally, H3C’s S7500E V7 Series switches support access methods such as VPLS (Virtual Private LAN Service), VLL (Virtual Leased Line), Hierarchical VPLS, and QINQ+VPLS Dual Tags, providing an end-to-end Layer 2 VPN access solution.< /p>

High performance for IPv4/IPv6 services

H3C’s S7500E V7 series switches feature a dual IPv4/IPv6 stack, which provides a comprehensive IPv4/IPv6 solution with support for multiple tunnels, IPv4/IPv6 Layer 3 routing protocols, multicast and policy-based routing. The S7500E V7 series switches are a mature commercial product for IPv6 networks.

MACsec hardware encryption technology

Switches H3C’s S7500E V7 series supports MACsec (802.1ae) hardware encryption technologies, industry standard security for protecting all traffic transmitted over Ethernet links. Compared to traditional application-level software encryption technologies, MACsec technology secures point-to-point Ethernet links between directly connected nodes and is capable of detecting and preventing most security threats.
