the storage pool. It will then examine the initiator WWNs that were associated with each of the
storage pool entries and perform the required assignment to the server in order to enable server
visibility within the SAN to the set of SAN volume targets defined by the storage pool entries.
This approach has the advantage of still being able to separate the boot and data storage visibility
to the server during OS provisioning without requiring any access to the existing SAN
management interfaces. The approach is limited to Virtual Connect managed servers only. For
additional information, see the Insight Dynamics – Automated Storage Provisioning: “Static” SAN
volume automation through multi-initiator NPIV white paper in the

or contact your HP support representative.
The second approach is called “Dynamic” SAN volume automation via LUN masking. In this
approach, SAN volumes are pre-created but are not yet masked to one or more initiator WWNs.
Zoning must be pre-configured. The SAN volumes are made available within Virtualization
Manager’s storage pool as storage pool entries. At service creation, Insight Orchestration selects
one storage pool entry. The storage pool entry must fully match the storage requirements for the
logical server in terms of number SAN volumes, size, RAID level, and optionally a set of one or
more tags. Different than the Flex-FC approach above, Insight Orchestration is able to perform
automatic LUN masking and host mode assignment. This allows Insight Orchestration to separate
the visibility of boot and data storage during OS provisioning. It also allows a single storage pool
entry to be re-used across different logical servers because the host mode may also be set
dynamically based on the logical server’s requirements. The approach has the advantage of being
supported for both Virtual Connect managed servers and non-Virtual Connect managed servers.
This approach does require that a SAN administrator be willing to grant restricted access to the
disk array management interface for performing the SAN volume inventory and LUN masking
operations. Storage administrators can grant specific server administrators, or groups of
administrators, these capabilities using the Storage Provisioning Manager (SPM). SPM enables
the storage administrator to create catalog entries representing the pre-provisioned SAN volumes
and have granular control over operations (some may support LUN masking and changing host
mode, others may not). This provides much more granular control than giving the server
administrator the Admin password to the storage array.

Insight Orchestration approach to storage reservation and allocation
A key step in the service creation process involves both a reservation and allocation phase for
all resources required by the service template. The following approach is followed when
performing storage reservation and allocation. The resource set that is being analyzed is always
the storage pool entries defined within Virtualization Manager.
•
Seek a storage pool entry (SPE) that contains a fully matched boot disk per the logical server’s
boot disk definition.
a.
If found, seek one or more additional SPEs that fully match the logical server’s data
disk definitions.
b.
If not found, pause the request and raise an email alert (using an Operations
Orchestration workflow) requesting manual storage provisioning for the data disks.
•
If the boot disk reservation could not be satisfied, fall back to seeking a single SPE which
fully matches both the logical server's boot disk and data disk requirements.
•
If the boot disk reservation still cannot be satisfied, fall back to seeking a single SPE which
fully matches the logical server’s boot disk definition.
a.
If found, pause the request and raise an email alert requesting manual storage
provisioning for the data disks.
•
If the boot disk reservation still cannot be satisfied, pause the request and raise an email
alert requesting manual storage provisioning for the boot disk.
