MX10008 System Overview

 

The MX10000 line of 5G Universal Routing Platforms give cloud and service providers the performance and scalability needed to outpace increased traffic demands. MX10008 provides 10-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet modular solutions that support up to 19.2 Tbps of throughput. MX10008 provides redundancy and resiliency. All major hardware components including the power system, the cooling system, the control board and the switch fabrics are fully redundant.

MX10008 Hardware Overview

Juniper Networks MX10008 Universal Routing Platform enables cloud and data center operators to transition from 10-Gigabit Ethernet and 40-Gigabit Ethernet networks to 100-Gigabit Ethernet high-performance networks. The 13 rack unit (13 U) modular chassis can provide 19.2 Tbps of throughput and 20 Bpps of forwarding capacity. The MX10008 router has eight slots for the line cards that can support a maximum of 768 10-Gigabit Ethernet ports, 192 40-Gigabit Ethernet ports, or 192 100-Gigabit Ethernet ports.

The MX10008 universal router provides 2.4 Tbps per slot fabric capacity for the service providers and cloud operators. You can deploy the MX10008 router in an IP edge network using an MX10K-LC2101 line card (ordering model number is JNP10K-LC2101).

You can deploy MX10008 in the edge of the network for the following functions:

  • Layer 3 Peering

  • Data Center Gateway

  • VPLS aggregation

  • Layer 3 Aggregation

  • Video Distribution

The MX10008 router is available in both base and redundant configurations for both AC and DC operation. MX10008 features front to back airflow (also know as airflow out or AFO).



Benefits of the MX10008 Router

  • System capacity— MX10008 scales to 19.2 Tbps (38.4 Tbps half- duplex) in a single chassis, with support for up to 768 10-Gigabit Ethernet, 192 40-Gigabit Ethernet, and 192 100-Gigabit Ethernet interfaces.

  • Full-scale IP and MPLS routing—MX10008 delivers the distributed peering scale of 7 million entries in the forwarding information bases (FIBs, also known as forwarding table) and 80 million routing information base entries (RIBs, also known as routing tables).

  • Source Packet Routing in Networking (SPRING)—SPRING on MX10008 provides additional flexibility per packet source. SPRING provides features such as network path and node protection to support MPLS fast reroute (FRR) mechanisms, enhanced network programmability, OAM functionality, simplified network signaling, load balancing, and traffic engineering functions.

  • Always-on infrastructure base—MX10008 is engineered with full hardware redundancy for cooling, switch fabric, and host subsystems—Routing and Control Boards (RCBs)—allowing service providers to meet stringent service-level agreements across the core.

  • Nondisruptive software upgrades—The Junos operating system on MX10008 supports high availability (HA) features such as graceful Routing Engine switchover (GRES), nonstop active routing (NSR), and unified in-service software upgrade (unified ISSU), providing software upgrades and changes without disrupting network traffic.

Chassis Description

MX10008 is 13 U tall. Up to three MX10008 routers can fit in a standard 39 U rack with adequate cooling and power. All key MX10008 router components are field-replaceable units (FRUs). Figure 1 illustrates the key components visible from the front of the chassis.

MX10008 Routing and Control Board

The Routing and Control board (RCB) (see Figure 4) contains a Routing Engine and is responsible for the system management and control in the MX10008. See MX10008 Routing and Control Board Description. RCBs are FRUs that are installed in the front of the chassis in the slots labeled CB0 and CB1. The base configuration has a single RCB while the fully redundant configuration has two RCBs. The RCB also contains Precision Time Protocol ports and two Media Access Control Security (MACsec) capable ports (see MX10008 Components and Configurations).

MX10008 Line Card (MX10K-LC2101)

MX10008 has eight horizontal line card slots and supports line rate for each line card. The line cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. The MX10008 line card architecture is based on a number of identical, independent Packet Forwarding Engine slices each with 400 Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line card slots labeled 0 through 7 (top to bottom) on the front of the chassis. All line cards are hot-removable and hot-insertable. After the hot insertion, the line card comes online automatically.

The MX10K-LC2101 line card is available for the MX10008. The MX10K-LC2101 line card can support 24 100-Gigabit Ethernet ports with a 28-Gbps quad smallform-factor pluggable (QSFP28) transceiver, or 24 40-Gigabit Ethernet ports with a QSFP transceiver. The MX10K-LC2101 line cards also support 10-Gigabit Ethernet interfaces. For 10-Gigabit Ethernet, you must configure the port using the channelization command. Because there is no port-groups option for the 100-Gigabit Ethernet line card, you must use individual port channelization commands.

Figure 5 shows the MX10K-LC2101 line card.

Switch Fabric Boards

Five Switch Fabric Boards (SFBs) provide the necessary switching functionality to an MX10008 router. A sixth SFB is available in the redundant configuration to provide n+1 redundancy. SFBs are installed between the line cards and the fan trays inside of the chassis (see Figure 6). Each MX10008 SFB has eight connectors that match to a line card slot, eliminating the need for a backplane. When all the six SFBs are installed, the MX10008 router has a net switching capacity of 2.4 terabytes per second (bidirectional). See MX10008 Switch Fabric Board Description.

Cooling System

The cooling system in an MX10008 router consists of two hot-removable and hot-insertable FRU fan trays (see Figure 7) and two fan tray controllers (see Figure 8).

Two fan tray models and their associated fan tray controllers are available. Both models of fan tray contain 11 fans. The fan trays install vertically on the rear of the chassis and provide front to back chassis cooling. For model differences, see MX10008 Cooling System and Airflow.

MX10008 Power Supplies

Power supplies for the MX10008 router are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each MX10008 router with a base configuration has three power supplies; redundant configurations hold a maximum of six AC, high-voltage alternating current (HVAC), DC, or high-voltage direct current (HVDC) power supplies. Each power supply has an internal fan for cooling. See Figure 9 through Figure 12.

Caution

Do not mix power supply models in the same chassis in a running environment. DC and HVDC can coexist in the same chassis during the hot swap of DC for HVDC.

MX10008 Component Redundancy

The MX10008 router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components in the redundant configuration provide redundancy:

  • Routing and Control Board (RCB)—The RCB consolidates the Routing Engine function with the control plane function in a single unit. The MX10008 router can have one RCB in a base configuration or two RCBs in a redundant configuration. When two RCBs are installed, one functions as the master and the other functions as the backup. If the master RCB (or either of its components) fails, the backup can take over as the master. See MX10008 Routing and Control Board Description.

  • Switch Fabric Boards (SFBs)—The MX10008 router has six SFB slots. Five SFBs are required for base operation and the sixth SFB provides n+1 redundancy. All six SFBs are active and can sustain full throughput rate. The fabric plane can tolerate one SFB failure without any loss of performance. See MX10008 Switch Fabric Board Description.

  • Power supplies—The MX10008 router requires three power supplies for minimum operation. Additional power supplies, provide n+1 redundancy for the system. AC, DC, HVAC, and HVDC systems tolerate a single power supply to fail without system interruption. If one power supply fails in a fully redundant system, the other power supplies can provide full power to the MX10008 router indefinitely.

    The MX10008 router also supports source redundancy. Two sets of lugs are provided for the JNP10K-PWR-AC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each JNP10K-PWR-AC2 power supply.

  • Cooling system—The fan trays have redundant fans, which are controlled by the fan tray controller. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely. See MX10008 Cooling System and Airflow.
