# Scenario:
7-
Production SQL Server & database(s) reside on a VMFS datastore. Non-production SQL Server resides on
8-
a different VMFS datastore. User database(s) data and log files reside on two different VMDK disks
9-
in each datastore.
10-
<BR><BR>
11-
Each datastore also resides on a different FlashArray, to demonstrate use of async snapshot replication.

<BR><BR>
137
This example is for a repeatable refresh scenario, such as a nightly refresh of a production database on
148
another non-production SQL Server.

a different VMFS datastore. User database(s) data and log files reside on two different VMDK disks
12+
in each datastore. This workflow is intended to only be impact select Windows Disks/VMDKs that contain user
13+
databases. Each datastore also resides on a different FlashArray, to demonstrate use of async snapshot

replication.

This example's workflow takes an on-demand snapshot of the Production datastore and async replicates it to
1717
the second FlashArray. Then the snapshot is cloned as a new temporary volume/datastore. The VMDKs with the
1818
production database files, residing on the temporary cloned datastore are attached to the target SQL Server,
1919
replacing the prior VMDKs that stored the database files previously. Finally Storage vMotion is used to
2020
migrate the VMDKs to the non-production datastore, then the temporary cloned datastore is discarded.
