# Configuration syntax:
# Spaces at head of line are deleted, other spaces are as separator
# Lines starting with '#' are comments and not evaluated.
# Lines ending with '\' are concatenated with the next line.
# Bracketed keys are section keys grouping the following value keys.
# Number of section key is used as a tag number.
#  Ex. [TargetNode1] = TargetNode section key with tag number 1

  # Users can restrict work items to only run on certain cores by
  #  specifying a ReactorMask.  Default ReactorMask mask is defined as
  #  -c option in the 'ealargs' setting at beginning of file nvmf_tgt.c.
  #ReactorMask 0x00FF

  # Tracepoint group mask for spdk trace buffers
  # Default: 0x0 (all tracepoint groups disabled)
  # Set to 0xFFFFFFFFFFFFFFFF to enable all tracepoint groups.
  #TpointGroupMask 0x0

  # Set the optional in-capsule data byte length for I/O queue capsule size.
  # Accepted values must be divisible by 16 and less than or equal to
  # the default maximum transfer length NVMF_MAX_RECV_DATA_TRANSFER_SIZE.
  # A minimum recommended value of 1024 bytes allows NVMf connect
  # commands to use in-capsule data.  Specifying a value greater than 4096
  # will allow NVMf write requests <= 4096 in length to use in-capsule
  # immediate data and bypass the need to perfrom an rdma_read operation
  # to pull the data from the host.

  # Set the maximum number of NVMf logical controller sessions allowed
  # for each subsystem provisioned below.  The default value (1) is used if

  # Set the global default maximum queue depth to a value less than the
  # default (128).  This value used for initial global pool allocation of
  # QP Rx/Tx descriptors and staging buffers.  The actual queue depth
  # used is negotiated during connection establishment, the remote
  # initiator having the opportunity to specify a smaller value.

# Users must change the Port section(s) to match the IP addresses
#  for their environment.
# Port sections define which fabric network ports the NVMf server
#  will use to listen and accept incoming connections.  A Port is
#  also used to control which ports will be used for each individual
#  NVM subsystem controller session, providing a means to distribute NVMf
#  traffic across all network ports.

# NVMe Device Whitelist
# Users may specify which NVMe devices to claim by their PCI
# domain, bus, device, and function. The format is dddd:bb:dd.f, which is
# the same format displayed by lspci or in /sys/bus/pci/devices. The second
# argument is a "name" for the device that can be anything. The name
# is referenced later in the Subsystem section.
#
# Alternatively, the user can specify ClaimAllDevices. All
# NVMe devices will be claimed and named Nvme0, Nvme1, etc.

# Users should change the Subsystem section(s) below to define the
#   set of local NVMe resources that will be accessible by specific groups
#   of hosts.  These mappings will be inspected to approve
#   remote fabric transport and NVMf protocol connection requests.
#
# Each approved NVMf connection represents a specific virtual controller
#   session within the NVMf subsystem.  Any such session is allowed access
#   to all NVMe namespaces within the subsystem.
#
# SubsystemName, Mapping, Controller0 are minimum required
# The SubsystemName is concatenated with NodeBase above to form the NVMf
#   subsystem NQN that will be used by remote initiator to identify the
#   target subsystem for connection.
# The Mapping defines the local fabric network port to be used by remote
#   connecting initiator.  Multiple mappings can be used to permit shared
#   access to the same subsystem.
# Each Controller identifies a specific HW device from the Nvme whitelist
#   section above.
