[+|-] Resiliency
With the power of the E-Series architecture, the Force10 E-Series delivers breakthrough resiliency at performance levels never before realized. The Force10 E-Series architecture is the result of patented technological innovation in switch fabric, backplane, ASIC and system control plane design.
Separate System Control Plane
The E-Series architecture includes distinct data and control planes. The system control plane is augmented with three processors on each route processor module (RPM). The first processor handles Layer 2 control protocols, the second, Layer 3, and the third, management functions. This patented
architecture allows faults to be contained while protecting other parts of the system. For example, it protects against spanning tree loops and DoS attacks providing unparalleled resiliency.
Designed to meet the needs of Internet-scale networks, the E-Series system control plane supports millions of routing table entries, up to 512K IPv4 forwarding table entries, and thousands of ACLs on every line card. The RPM’s innovative control traffic rate limiting and filtering functionality empowers network administrators to suppress harmful DoS attacks and prevent flooding of unwanted traffic onto the network. And dedicated 100 Mbps switched paths from the RPMs to every line card eliminate sluggish forwarding table updates that could otherwise jeopardize network stability.
Distributed ASIC-based Forwarding
The Force10 ASICs, along with advanced TCAMs on every line card, give absolutely predictable line-rate forwarding for every packet regardless of the number, type or complexity of features enabled across the chassis. Unlike low-performance, processorbased forwarding architectures, there is no
“slow-path” or software-based forwarding in the E-Series. The Force10 ASICs look up and act upon all information related to forwarding and applying policy to a packet before the entire packet is received, independent of table lengths, IP address prefix lengths or packet size. This hardware
forwarding enables the E-Series to provide the deterministic low latency and jitter required by VoIP and streaming media applications.
Non-blocking 1.6875 Tbps Switch Fabric
The E-Series switch fabric provides nonblocking connectivity along with advanced
queuing, multicast and jumbo frame support. The E600/E1200’s cost-effective N:1
redundant switch fabric design reduces SFM sparing costs while providing 56.25 Gigabits per second of non-blocking bandwidth to each line card slot.
Passive Copper Backplane
The E-Series architecture’s reliable and cost-efficient backplane is the industry’s first high speed, nonoptical backplane to scale to 5 Tbps data rates in a single 1/2 rack E1200 switch/router chassis. Unlike optical backplane interconnect systems or active copper backplanes, the E-Series backplane has no single point of failure and eliminates costly electrical-optical-electrical conversions. The resulting system simplicity afforded by the backplane means bulletproof reliability and minimum cost — available on all three platforms. The massive backplane capacity of E-Series chassis bought today also translates to enough bandwidth per slot (E600 and E1200) to support 40 and 100 GbE standards when they become available.
Fault Tolerance and High Availability
The E-Series architecture supports redundancy, availability and serviceability features to maximize network uptime. All key systems in the E-Series are redundant, including the RPMs, SFMs and power. All memory systems are ECC/parity protected. System-wide environmental monitoring and persistent configuration synchronization enable FTOS to detect, report and correct faults with a minimum of system interruption. In addition, serviceability features include hot-swap of all key components, cable management, and front-side access to all cabling and cards minimize mean time to repair.
[+|-] Scalable Performance
To simplify network operation and maintenance, the E300, E600 and E1200 allow hot-swap of all key components and
share the same switch fabric modules (SFMs) and FTOS software. In addition, the E1200 and E600 share common line cards
and route processor modules (RPMs).
The Force10 E-Series sets a new standard for high performance switch/routers with unmatched scalability to 1,260 Gigabit Ethernet or 224 Ten Gigabit Ethernet ports per chassis, consistent performance with ACLs on all ports, and full L2 switching and L3 routing. These groundbreaking products simplify network applications from server/ cluster consolidation, grid computing, campus backbones, next-generation Internet Exchanges, and Metro Ethernet services.
The Force10 E-Series E1200/E600 provides 56.25 Gigabits per second per slot and the E300 delivers 25 Gigabits per second per slot. All deliver predictable line-rate performance with any combination of features enabled, deterministic low latency and jitter, robust L2/L3 functionality, and the resiliency to thwart denial of service (DoS) attacks. Built upon the powerful and cost-effective Force10 architecture, the E-Series sets the
industry standard
both for resiliency
and performance.
