# Indicates that the resource provider decorated with this trait exposes
|
|
# its resources for consumption on *other* resource providers via an
|
|
# aggregate association. The canonical example here would be a shared
|
|
# storage pool.

# The deployer might create a resource provider, let's call it "NFS_SHARE"
|
|
# that has an inventory record of 2000 total DISK_GB resources.
|
|
#
|
|
# There may be 10 other resource providers, let's call them "CN_1" through
|
|
# "CN_10" that represent compute nodes. These compute node resource
|
|
# providers have inventory records for MEMORY_MB and VCPU resources, but no
|
|
# DISK_GB inventory.
|
|
#
|
|
# Both the "NFS_SHARE" resource provider and each of the "CN_x" resource
|
|
# providers are associated to the same aggregate, let's call it "AGG_A".
|
|
#
|
|
# Deployers would decorate the "NFS_SHARE" resource provider with the
|
|
# "MISC_SHARES_VIA_AGGREGATE" trait to indicate to the system that the
|
|
# DISK_GB inventory it provides can be consumed by consumers of resources
|
|
# on any of the other resource providers associated with any aggregate
|
|
# "NFS_SHARE" is associated to.
