Two Separated Datastores

Figure 12 shows two separated datastores.

Figure 12. Two Separated Datastores

In this design, the source vApp template resides on Datastore 1 in Org vDC1. A template was cloned to Datastore

2, which was accessed by one of the two ESX hosts managed by Org vDC 2.

Because ESX hosts in Org vDC 2 did not have access to Datastore 1, the vApp template was uploaded to the cell

first, and then a deployment OVF package API call was issued to the vCenter Server that was mapped to Org

vDC 2.

Datastore Shared Among ESX Hosts

If ESX hosts in Org vDC 2 have access to the same datastore as shown in Figure 13, the process to upload the

vApp template OVF package and then deploy it to vCenter Server can be replaced by single file copy API calls to

vCenter Server. This design improves performance dramatically. We discuss this in “OVF File Upload” on page 10

with more details.
