# ix.conf
# configuration file for IX
#
# This file defines the configuration for IX data center OS. You should
# carefully update all fields in accordence with your local configuration
# before running IX for the first time.
###############################################################################
# Network Parameters
###############################################################################
## host_addr : CIDR IP address and netmask that will be assigned to
## the adapter once it comes up.
host_addr="192.168.40.1/16"
# gateway_addr : default gateway IP address
gateway_addr="192.168.1.1"
## port : port(s) that will be bound to the application by the
## kernel when launching IX.
## You can specify multiple entries, e.g. 'port=[X, Y, Z]'
port=1234
###############################################################################
# Hardware parameters
###############################################################################
## devices : Specifies the PCI device ID of the adapter to bind IX with.
## Should be an Intel compatible NIC (e.g. 82599, X520, X540, etc)..
## See the Docs to see which adapters are currently supported.
## Format is a list dddd:bb:ss.ff,... d - domain, b = bus,
## s = slot, f = function. Usually, `lspci | grep Ethernet` allows to see
## available Ethernet controllers. Similarly, `lspci | grep Non-Volatile`
## allows to see available NVMe SSD controllers.
## You can specify multiple entries, e.g. 'devices=["X","Y","Z"]'
devices="0:05:00.0"
nvme_devices="0:04:00.0"
###############################################################################
# ReFlex I/O scheduler parameters
###############################################################################
# nvme_device_model: "sample.devmodel" is a sample config file for a device model
# which specifies read/write costs and token limits for
# tail latency SLOs; values are device-specific
# You should follow instructions in this file to modify
# values corresponding to the performance of your SSD.
# Either modify sample.devmodel directly or copy to a
# different file and specify file name here.
# "default" for no token limits
# "fake" models ultra low latency device since we don't
# submit I/Os to real device, just generate fake I/O
# completion events (can be useful for perf debugging)
#
# scheduler: "on" (by default)
# "off" means I/O submitted directly to flash,
# no SW queueing, no QoS scheduling
nvme_device_model="sample.devmodel"
scheduler="on"
## cpu : Indicates which CPU process unit(s) (P) this IX instance
## should be bound to.
## WARNING: If this setting defines multiple nodes, make sure they ar
## part of the same NUMA socket. On most architectures, the IDs of
## processing units on the same socket are interleaved.
## Usually `lstopo` allows to see NUMA nodes topology
## You can specify multiple entries, e.g. 'nodes=["X","Y","Z"]'
cpu=0
## batch : Specifies maximum batch size of received packets to process.
## Default: 64.
batch=64
## loader_path : kernel loader to use with IX module:
##
loader_path="/lib64/ld-linux-x86-64.so.2"
###############################################################################
# Optional parameters
###############################################################################
## arp: Allows you to manually add static arp entries in the interface arp table
#
#arp=(
# {
# ip : "192.168.1.2"
# mac : "aa:aa:aa:aa:aa:aa"
# },
# {
# ip : "192.168.1.3"
# mac : "bb:bb:bb:bb:bb:bb"
# }
#)
## fdir : Static flow director rules to be added to NIC
# Use this to steer traffic to particular cores when multi-core ReFlex.
# Queue number corresponds to CPU core id
#
##fdir=(
# {
# dst_ip : "192.168.40.1"
# src_ip : "XX.XX.XX.XX"
# dst_port : 1234
# queue : 0
# },
# {
# dst_ip : "192.168.40.1"
# src_ip : "YY.YY.YY.YY"
# dst_port : 5678
# queue : 1
# }
