HP 12508 AC Switch Chassis (JF431C)

• Multitenant Device Context (MDC): is an innovative data center virtualization solution that enables multi-tenancy, giving customers the ability to virtualize a physical switch into multiple logical devices, with each logical switch having its own tenants

• HP Ethernet Virtual Interconnect (EVI): is an HP Virtual Application Network innovation that provides a Layer 2 extension across the data center to simplify the interconnectivity of geographically disperse data centers

• In Service Software Upgrade (ISSU): is a modular operating system that, together with a distributed architecture, provides an upgrade of the entire chassis or an individual task/process without impacting hardware forwarding

• Very high performance without compromise: leveraging the latest generation of ASICs, the 12500 switch series offers outstanding performance and density to build next-generation data centers; delivers a routing/switching capacity of up to 13.32 Tbps and a throughput of 4320 Mpps (12518 switch), 6.12 Tbps and 1920 Mpps (12508 switch), or 3.24 Tbps and 960 Mpps (12504 switch)

• Very high-density 10GbE connectivity: the 12518 switch supports up to 576 10GbE (4:1) or 288 10GbE (1:1) per physical rack (44RU); the 12508 switch supports up to 256 10GbE (4:1) or 128 10GbE (1:1); with two 12508 switches per physical rack (44RU), the density becomes 512 10GbE (4:1) or 256 10GbE (1:1); the 12504 switch supports up to 128 10GbE (4:1) or 64 10GbE (1:1)

• Intelligent Resilient Framework (IRF): creates virtual resilient switching fabrics, where two or more switches perform as a single L2 switch and L3 router; switches do not have to be co-located and can be part of a disaster recovery system; servers or switches can be attached using standard LACP for automatic load balancing and high availability; can eliminate the need for complex protocols like Spanning Tree Protocol, Equal-Cost Multipath (ECMP), or VRRP, thereby simplifying network operation

• Ultrafast protocol convergence: enables link connectivity monitoring and reduces network convergence time for RIP, OSPF, BGP, IS-IS, VRRP, MPLS, and IRF

• Device Link Detection Protocol (DLDP): monitors link connectivity and shuts down ports at both ends if unidirectional traffic is detected, preventing loops in STP-based networks

• Complete set of routing protocols (Layer 3 IPv4 and IPv6): support virtually all existing routing protocols (RIP, OSPF, IS-IS, and BGP) for both Layer 3 IPv4 and Layer 3 IPv6; complete support of PIM-DM, PIM-SM, PIM-SSM, and MSDP

• Hot patching: the 12500 switch series supports hot patching, allowing in-service patching for some isolated software problems

• 13.32 Tbps (12518 switch), 6.12 Tbps (12508 switch), and 3.24 Tbps (12504 switch) fully nonblocking CLOS architecture: includes a high-performance switch design with a nonblocking architecture

• High-performance bandwidth: with up to 13.32 Tbps capacity, providing nonblocking throughput for 288 10GbE ports at Layer 2 and Layer 3 IPv4, Layer 3 IPv6, and MPLS (12518 switch), 128 10GbE ports (12508 switch), or 64 10GbE ports (12504 switch)

• Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps provide high levels of security and ease of administration without impacting network performance

• High-performance processor system: the supervisory module uses three different processors to isolate key tasks: control plane (STP, OSPF, BGP, MPLS, etc.), fast recovery protocols (RRPP, BFD, etc.), and chassis management (temperature, power, etc.)

• Virtual Output Queue (VOQ): prevents head-of-line (HOL) blocking per port at peak time and distributes it over a period of time, increasing switch performance

• IEEE 802.1p prioritization: delivers data to devices based on the priority and type of traffic

• Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers

• Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic

• Advanced classifier-based QoS: classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a per-port or per-VLAN basis
