Purpose

This document describes the UDSP feature from the user perspective. The document will cover all Intended use cases, list expected behaviour and potential issues for each.

UDSP Use Cases

Linux Routing

Because all use cases featured below rely on having multiple interfaces configured, it is important to make sure that linux routing is configured according to guidelines listed here: MR Cluster Setup

Local Peer Config

The following configuration is used for local testing.

UDSP

Behaviour

Prioritize one of PeerA NIDs on tcp

Prioritized nid is used when its net (tcp) is used on peerA

Priority of the nid is 0. Other nids' priority is -1 (default, no priority)

Every send toggles between the prioritized nid on tcp and the nid on tcp1 on the source. The remaining nid on tcp is not used

"netstat -i" command shows tx stats incrementing for eth2 and eth0 on peerA

Code Block
lnetctl udsp add --src 192.168.122.110@tcp lnetctl udsp show udsp: - idx: 0 src: 192.168.122.110@tcp dst: NA rte: NA action: priority: 0

Local Source Net

UDSP

Behaviour

Prioritize tcp1 as source on PeerA

Note that source NID rule is still in the list.

Prioritized tcp1 is used on PeerA

Priority of tcp1 is 0 (highest)

Every send on PeerA goes out tcp1. NID rule is overriden.

"netstat -i" command shows tx stats incrementing for eth2 on peerA

Code Block

Prioritize Destination

Local Destination NID

UDSP

Behaviour

On PeerA, prioritize one of PeerB's NIDs on tcp

Prioritized NID on PeerB is sent to when tcp is selected on peerA

Priority of the prioritized NID is 0 (lnetct peer show -v 4)

Sends on PeerA alternate between tcp and tcp1. When tcp is used, send goes to the prioritized dest NID

"netstat -i" command shows rx stats incrementing for eth2 and eth0 on peerB

Local Destination Net

UDSP

Behaviour

On PeerA, prioritize tcp1 as dest net

Prioritized dest net (tcp1) is used to send from PeerA

Priority of the prioritized dest net is 0 (lnetct peer show -v 4)

Sends on PeerA use tcp1.

"netstat -i" command shows tx stats incrementing for eth2 on peerA

Prioritize Destination

Local Destination NID

...

On PeerA, prioritize one of PeerB's NIDs on tcp

...

Prioritized NID tcp NID on PeerA is used when tcp is selected on peerA

Priority of the prioritized NID is 0 (lnetct peer show -v 4)

Sends on PeerA alternate between tcp and tcp1. When tcp is used, send goes to the prioritized dest NID

priority: 0

PeerB: use "lnetctl net show -v" to verify the receive count going up on the nids of the prioritized dest net

PeerA: use "lnetctl peer show -v 4" to verify dest net priority.

NID Pairing

Local Destination NID Pairing

UDSP

Behaviour

On PeerA, pair one of the tcp nids with one off the PeerB tcp nids

When paired nid on PeerA is selected, it always sends to its pair on peerB

PeerA nid is listed as preferred NID for the peerB nid ("lnetctl net show -v")

UDSP

Behaviour

On PeerB, add UDSP that gives one of the PeerA nids highest priority

On PeerB, designate Gateway1 as preferred for the same PeerA nid.

All sends from PeerB go to the prioritized nid of PeerA through the preferred gateway

Use "lnetctl stats show" on Gateway1 and Gateway2. On every send from PeerB to

the prioritized nid of PeerA through the preferred gateway

PeerA, "route_count" should increase only on Gateway1. On PeerA "send_count" and "recv_count" should increase only for the prioritised nid. On PeerB, Gateway1 should be listed as preferred for the specified nid of PeerA on tcp

"netstat -i" command shows rx stats incrementing for eth0 on peerA
