For migrating a Microsoft SQL Server and its native EMC VNX LUNs behind a VPLEX Local cluster with the ability to expand storage volumes in the future, the recommended geometry during encapsulation is 1:1 mapping.This approach allows for each storage volume to be directly mapped to a virtual volume, preserving the data in its current state and simplifying future expansions1.

1:1 Mapping: This geometry ensures that each back-end storage volume is encapsulated into a corresponding virtual volume in VPLEX.It maintains a direct relationship between the physical LUN and the virtual volume1.

Future Expansion: With 1:1 mapping, expanding a virtual volume is straightforward because it involves expanding the underlying storage volume on the array and then resizing the corresponding virtual volume in VPLEX1.

Encapsulation Process: During encapsulation, the storage administrator can prepare many tasks ahead of time, such as host zoning to VPLEX FE ports, host registration of initiators in VPLEX, and LUN masking/zoning to the VPLEX BE Ports.The cutover process then becomes a quick procedure to switch the volumes1.

EZ Provisioning Wizard: After claiming and encapsulating the LUNs, the administrator can create a 1:1 mapping of Storage volume to virtual volume with the EZ Provisioning Wizard, which is a quick process and helps preserve the data in its current state1.

Simplifying Management: By using 1:1 mapping, the storage administrator simplifies the management of storage volumes and ensures that the SQL Server can be easily expanded to accommodate future application growth1.

By selecting 1:1 mapping during the encapsulation process, the storage administrator ensures that the system is prepared for future growth and that storage volumes can be expanded without complications.
