PE3100G2DBIRM Content Director Server Adapter

Dual Port Fiber 100 Gigabit Intel® FM10840 Based

Silicom’s 100 Gigabit Ethernet PCI Express content aware director Bypass server adapters for multi-host platform connectivity is designed for servers and high-end appliances. The Silicom content aware director server adapter is designed with an on board smart routing architecture that enables packets to be redirected or dropped based on defined rules.

The Silicom’s 100 Gigabit Ethernet content aware packet director for multi-host platform connectivity reduces host system process since only packets that are defined to be targeted to the host systems are routed to the host; other packets can be routed to the other port or can be dropped by the content aware hardware routing architecture.

The Silicom’s 100 Gigabit Ethernet content aware packet director for multi-host platform connectivity is targeted to network applications that needs to process, monitor or bypass packets based on defined rules. The adapter supports three main modes of operation: Content Aware Bypass, Content Aware TAP and content Aware filtering NIC.

Functional Description

Director Director - Content Aware Bypass

Silicom’s 100 Gigabit Ethernet content aware director Provides intelligent packet redirection capability where rules specify which packets are directed to the host system and which packets are directed to the other port (Bypass)

content director server adapter 2

Figure 1: Content Aware Bypass Functional Block Diagram

 

Figure 1 illustrates example of functional block diagram of content aware Bypass:

Packets received in port A and meet rule are directed to port C and D, other packets are directed to port B (Bypass).

Packets received in port B and meet rule are directed to ports E and F, other packets are directed to port A (Bypass).

 

Director - Content Aware TAP
Silicom’s Ethernet content aware director Provides intelligent packet redirection capability where all packets are directed to the other port (Bypassed) and rules specify which packets are copied to the host system (TAP).

Figure 2: Content Aware TAP Functional Block Diagram

 

Figure 2 illustrates example of functional block diagram of content aware TAP:
Packets received in port A and meet rule are directed to ports B nad C (TAP), other packets are directed to port B (Bypass).

Packets received in port B and meet rule are directed to ports F and A (TAP), other packets are directed to port A (Bypass).

 

Director - Content Filtering NIC
Silicom’s Ethernet content aware provides intelligent packet redirection capability where rules specify which packets are directed to the host or dropped.

Figure 3: Content Aware Filtering NIC Functional Block Diagram

 

Figure 3 illustrates functional block diagram of content aware TAP:
Packets received in port A and meet rule, direct to port C and D. Packets received in port A and do not meet rule are dropped.

Packets received in port B and meet rule, direct to ports E and F. Packets received in port B and do not meet rule are dropped.

 

Director - Load balancing (*Future Support)
Silicom’s Ethernet content aware director provides a load balancing of the traffic coming from 2 100G external ports (A, B). The traffic is balanced, based on a defined hash configuration, to the 4x 50G internal interfaces (C,D,E and F) that are going to the host

Figure 4: Load Balancing Functional Block Diagram

 

If there is external port that is heavily loaded the traffic will go into the 4 internal interfaces with balanced load. An ISL tag is added to all incoming packets, it enables the host to know the source port, and the ISL tag is removed from packets that are sent back from the host.

 

Director - Tagged In-Line rule aware mode (*Future Support)

Silicom’s 100 Gigabit Ethernet content aware director Provides intelligent packet redirection capability where rules specify which packets are directed to the host system and which packets are directed to the other ports (Bypass) but at the same time it will get these bypassed traffic into the host with a ISL tag marking that these packets are bypassed, per the rules that the host will issue to the Silicom’s 100 Gigabit Ethernet content aware director.

Figure 5: Tagged In-Line rule aware mode Block Diagram

 

Figure 5 illustrates functional block diagram of Tagged In-Line rule aware mode:
Port Group (A,C,D), (B,E,F) configured as VLAN groups.
Packets received in the 2 x 100G external ports (A and B) and meet and are directed to the other ports of the Vlan group with ISL tag that notify that match found. The original packet is sent to the “Output Port of Switch” in the rule matched policy
Packets received in the 2 x 100G external ports (A and B) and do not meet the rule are directed to the other ports of the Vlan group taged with ISL tag that notify that no-match found.

 

Director: Rules Classification and capabilities

The Redirector supports the following capabilities:

Maximum total number of rules is 16K.

Each of the 16K rules can be defined to any port the on board multi-layer switch.

Each rule refers to incoming packet.

Rules are executed per order. First rule that matches will be executed.

Rules can be added and removed on the fly.

Each rule can include one or more classification fields. A rule match will be when all fields defined are match.

Each field can have a bit masking to check part of the classification field.

Per port statistics can be read, like packets count, errors, VLAN, and more.

Rules and action are done in wire speed at any packet size.

 

Rules classification fields

Rules classification is done based on the first 128 bytes of the packets. The following list provides rules classification fields.

MAC address, source & destination

IPv4 – source & destination IP

IPv6 – source & destination IP

L4 Port – source & destination port

Ethernet Protocol – ethertype

IP Protocol num.

VLAN ID tagging

User defined fields

DSCP – match the different services code point – the six most significant bits of the Type of Service octet (IPv4) or Traffic Class octet (IPv6).*

IPv6 Flow Label*

IP length*

ISL Frame Type*

ISL USER*

Source & destination port range*

VLAN priority*

VLAN tag type*

TCP flags*

TOS – match Type of Service octet (IPv4) or Traffic Class octet (IPv6)*

TTL field in a IPv4 header or Hop Limit in a IPv6 header*

*Future SW supports.

 

Execution per rule

The following Executions per rule are supported:

Drop – when a rule matches the packet will be dropped

Redirect – when a rule matches redirect the packet to the defined destination port

Mirror – when a rule matches copy packet also to a defined destination port

Director Advanced Features:

Port trunking between the different Intel ports to Intel ports connected to it for load balancing between the different Intel ports

Port trunking between the different External Intel port to the external switch connected to it for load balancing between the different external ports.

Session balancing with L3/L4 hashing or other mechanism

ISL (Inter Switch Link) Tagging per port can be added to the packets per configuration

ISL Tagging can be removed and can be forward to specific port per the ISL index.

Quality of Service support with the following features:

Priority levels: 16 internal "switch" priorities, 8 or 16 VLAN priorities (optional use of CFI bit as an extra VLAN priority bit)

Arbitrary mapping of ingress VLAN priority to an internal VLAN priority

Arbitrary mapping of an internal VLAN priority to egress VLAN priority

Arbitrary mapping of internal VLAN priority to switch priority

Arbitrary mapping of DSCP to switch priority, configurable priority source selection.

Scheduler: 8 traffic classes, arbitrary mapping of switch priorities to traffic class, deficit weighted round-robin or strict priority.

Notification: Two congestion notifications can be supported;

Virtual output queue congestion notification (VCN) and Intel proprietary backward congestion notification (FCN).

Open Flow support (consistent with OpenFlow protocol standard)

sFlow support

 

User defined Packet transmission with two optional modes: 1. Simple mode - transmit on specific port. 2. Switched mode - where switch determines destination port/ports, or with specific information such as whether or not egress processing rules should be applied.

Storm Control Management - Switch can support a variety storm controller. Each storm controller can be programmable to define rat, condition (like unicast ICMP frames whose TTL is at most 1), frame type (can be OR’ed), ingress & egress port ports. Actions: do nothing, drops frames to port (according to filter)

*Future SW supports.

 

Bypass/Disconnect Mode of operation

Silicom’s Bypass adapter supports the following mode states: Normal/inline, Bypass/Fail-To-Wire and Disconnect modes.

Normal/Inline mode
In Normal mode, the ports are independent interfaces (see Figure 6: Normal mode, one Bypass pair is illustrated).

Normal Mode Functional Block Diagram

 

Bypass/Fail-To-Wire mode
In Bypass mode, the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. The connections of the interfaces are left unconnected. (See Figure 7: one Bypass pair illustrated)

 

Figure 5: Bypass Mode Functional Block Diagram

 

Disconnect mode
In Disconnect mode, the transmit connections of the interfaces are disconnected from the ports. The switch / router connected to the adapter does not detect link partner (See Figure 8):

Figure 6: Disconnect Mode Functional Block Diagram

 

Bypass/Disconnect Features
Silicom’s Bypass server adapter supports software programmable to select Normal, Bypass or Disconnect modes. Silicom’s Bypass adapters supports Disable Bypass, Disable Disconnected capabilities; hence, if those adapters receive Disable Bypass capability / Disable Disconnect commands, the adapter does not Bypass / does not Disconnect its Ethernet ports, The Disable Bypass Capabilities are reserved also after power off. This feature enables to emulate a standard NIC.

 

Key Features:

All modes of operation are fully software configured with a well-defined and easy to use API.
Disable bypass/Disconnect for a standard NIC emulation and operation, retained even with power cycle
Range of Watchdog timer timing, configurable for detecting appliance failure.
Watchdog timer reset function by application or self-reset by the product bypass driver
Easy to read product status and product features capabilities
Fast switching between mode with less than 10mS of transit time
Compatible with all Silicom bypass products, one driver set and command set for all products.
