Resiliency And High Availability - HP 7510 Datasheet

• Packet storm protection: protects against
unknown broadcast, unknown multicast, or unicast
storms with user-defined thresholds
• Flow control: using standard IEEE 802.3x, it
provides back pressure to reduce congestion in
heavy traffic situations
• IEEE 802.3at Power over Ethernet (PoE+)
support: provides up to 30 watts of power at the
PSE
Performance
• High-speed fully distributed architecture:
– 2.4 Tbps backplane supports maximum 1152
Gbps switching capacity, providing enhanced
performance and future expansion capability; with
dual fabrics, the switch delivers up to 714 Mpps
throughput
– All switching and routing is performed in the I/O
modules
– Meets current and future demand of an
enterprise's bandwidth-intensive applications
• Scalable system design: backplane is designed
for bandwidth increases; provides investment
protection to support future technologies and
higher-speed connectivity
• Flexible chassis selection: enables customers to
tailor their product selection to their budget with a
choice of six chassis, ranging from a 10-slot to a
2-slot chassis

Resiliency and high availability

• Redundant/Load-sharing fabrics,
management, fan assemblies, and power
supplies: increase total performance and power
available while providing hitless, stateful failover
• All modules are hot-swappable: allows
replacement of modules without any impact on other
modules
• Dual internal power supply: provides high
reliability
• Separate data and control paths: keeps
control separated from services and keeps service
processing isolated; increases security and
performance
• Passive design system: backplane has no
active components for increased system reliability
• IEEE 802.3ad Link Aggregation Control
Protocol (LACP): supports up to 128 trunks, each
with 8 links per trunk; supports static or dynamic
groups and user-selectable hashing algorithm
• Intelligent Resilient Framework (IRF): creates
virtual resilient switching fabrics, where two or more
switches perform as a single Layer 2 switch and
Layer 3 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; simplifies network operation by
eliminating the complexity of Spanning Tree
Protocol, Equal-Cost Multipath (ECMP), or VRRP
• Rapid Ring Protection Protocol (RRPP):
provides standard sub-100 ms recovery for ring
Ethernet-based topology
• Virtual Router Redundancy Protocol
(VRRP): allows a group of routers to dynamically
back each other up to create highly available routed
environments
• Hitless patch upgrades: allow patches and new
service features to be installed without restarting the
equipment, increasing network uptime and
facilitating maintenance
• Graceful restart: features are fully supported,
including graceful restart for OSPF, IS-IS, BGP, LDP,
and RSVP; network remains stable during the
active-standby switchover; after the switchover, the
device quickly learns the network routes by
communicating with adjacent routers; forwarding
remains uninterrupted during the switchover to
realize nonstop forwarding (NSF)
• Ultrafast protocol convergence with
standard-based failure
detection--Bidirectional Forwarding
Detection (BFD): enables link connectivity
monitoring and reduces network convergence time
for RIP, OSPF, BGP, IS-IS, VRRP, MPLS, and IRF
• Smart link: allows 50 ms failover between links
• IP/LDP FRR: nodes are configured with backup
ports, routes, and LSPs; local implementation
requires no cooperation of adjacent devices,
simplifying the deployment; solves the traditional
convergence faults in IP forwarding and MPLS
forwarding, protecting the links, nodes, and paths
without establishing respective backup LSPs for
them; realizes restoration within 50 ms, with the
restoration time independent of the number of routes
and fast link switchovers, without route convergence
