4.3.1 Storage Tiering
Storage tiering in vCloud Director 5.1 is enabled on a per virtual machine basis through storage profiles:
Authoring, renaming
, and deletion
of storage profiles is performed through vSphere.
Storage profiles can be added, disabled, or removed at the
provider virtual datacenter
level.
All available storage profiles across selected clusters are listed at
provider virtual datacenter
creation.
Organization virtual datacenter
storage profiles are based on a subset of storage profiles provided by the provider virtual datacenter.
Each organization
virtual datacenter
has an associated
default storage profile.
All
virtual machines have an associated
storage profile that defaults to the organization
virtual datacenter
storage profile.
Virtual m
achine placement is based on storage profiles.
Other entities that support storage profiles include:
Templates.
Media.
Independent disks.
OVF storage profile
support:
vSphere does not export storage profile
association when exporting a virtual machine
to OVF.
VCD
template download exports a template virtual machine’s default instantiation profile.
VCD
template upload applies OVF-
specified template virtual machine’s default instantiation profile.
Disks independent of virtual machine:
Are associated with an organization virtual datacenter storage profile.
Allow selection of datastore to place the disk accounts for storage profile.
Can have their storage profile
changed.
Are a
llowed to be on a different storage profile
than the virtual machine
to which the disk is attached.
The following are vSphere changes that affect VCD
storage profiles:
Changed datastore labels.
Deleted storage profiles.
Changed virtual machine
storage profile
association.
Virtual machine
is migrated using VMware vSphere Storage vMotion
® to a new datastore.
Storage p
rofile compliance checks
are performed when:
Initiated through the REST API.
Automatically performed.
When a storage profile in use by an
organization virtual datacenter
is deleted in vCenter.
When a virtual machine is migrated using Storage vMotion.
Non-compliance shows up in the form of system alerts on the virtual machine.
