S7500E switch series has been one of the best-selling products since it has been released worldwide nine years ago, with H3C’s proprietary operating system upgrade from V5 to V7, S7500E switch series has revived and equipped the following benefits and features:
Upgraded per slot bandwidth and whole switch series performance
High port density 10G line cards
MDC (Multitenant Devices Context), EVI (Ethernet Virtualization Interconnect), VXLAN and MACsec
IRF2 (Intelligent Resilient Framework version 2)
Convergence of MPLS, VPN, and multiple services
MP-BGP based EVPN solution
These whole new switch series are perfectly for enterprise network upgrade and maximize your network ROI and reduce your TCO. The whole brand new S7500E V7 switch series include S7503E-M and S7506E-NonPoE.

High port density 10G line card

Supports high-density 48 port 10G interfaces line card and can meet the existing and future application requirements of data centers.

Virtualization technologies - IRF2

IRF2 can virtualize up to four S7500E V7 switches into one logical IRF fabric. IRF2 delivers the following benefits:
High Availability (HA) - Patented hot standby technology to provide data backup and non-stop forwarding on the control plane and data plane. This improves availability, performance, eliminates single-point failures and ensures service continuity.
Distribution - Multi-chassis link aggregation to enable load sharing and backup over multiple uplinks, improving redundancy and link utilization.
Easy Management - A single IP address to manage the whole IRF fabric, which simplifies device and topology management, improving operating efficiency, and lowering network maintenance cost.

Virtualization technologies – MDC Capability

MDC virtualizes one S7500E V7 switch (except S7503E-M) into multiple logical switches, enabling multiple services to share one core switch.
The 1:N virtualization maximizes switch utilization, reduces network TCO, and ensures isolation of services.

DC-oriented features

EVI is a MAC-in-IP technology that provides Layer 2 connectivity between distant Layer 2 network sites across an IP routed network. It is used for connecting geographically dispersed sites of a virtualized large-scale data center that requires Layer 2 adjacency.
VXLAN (Virtual Extensible LAN) — VXLAN uses a MAC-in-UDP encapsulation method where the original Layer 2 package is added with a VXLAN header, and is then placed in a UDP-IP packet. With the help of MAC-in-UDP encapsulation, VXLAN tunnels Layer 2 network over Layer 3 network which provides two major benefits: higher scalability of Layer 2 segmentation and better utilization of available network paths.
MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) uses standard-based BGP protocol as the control plane for VXLAN overlay networks, providing BGP based VTEP auto peer discovery and end-host reachability information distribution. MP-BGP EVPN delivers many benefits, such as eliminating traffic flooding, reducing full mesh requirements between VTEPs via the introduction of BGP RR, achieving optimal flow based end to end load sharing and more.

Comprehensive MPLS/VPLS capability

H3C S7500E V7 switch series supports Multi-VRF function, which can be used as MCE equipment supporting L3 MPLS VPN and L2 MPLS VPN (Martini and Kompella). It also supports MPLS OAM function, which brings easier management and maintenance. Working with H3C intelligent Management Centre (iMC) MPLS VPN Manager allows easy MPLS deployment and maintenance.
H3C S7500E V7 switch series also supports VPLS, VLL, hierarchical VPLS and QINQ+VPLS access methods, providing end-to-end layer 2 VPN access solution.

High-performance IPv4/IPv6 service capabilities

H3C S7500E V7 switch series comes with IPv4/IPv6 dual-stack platform that provides sophisticated IPv4/IPv6 solutions by supporting multiple tunnels, IPv4/IPv6 Layer 3 routing protocols, multicasting, and policy-based routing. The S7500E V7 switch series is a mature commercial IPv6 product that has passed the IPv6 network access certification of the Chinese Ministry of Industry and Information Technology and the IPv6 Ready Phase II certification.

Hardware level encryption technology MACsec

H3C S7500E V7 switch series supports hardware level encryption technology MACsec (802.1ae), which is an industry-standard security technology that provides secure communication for all traffic on Ethernet links. Compared with traditional application based software encryption technology, MACsec provides point-to-point security on Ethernet links between directly connected nodes and is capable of identifying and preventing most security threats.
