However, some features are logically grouped into add-on packages that must be licensed separately. Most software features are included in the base license. Switches from different vendors should be able to communicate with each other, and software interoperability plays a major role in helping ensure that they can.īefore SAN switch migration, it is important to obtain the correct license set for your switches. The planning and design phase involves both physical and architectural elements.Īrchitectural planning includes all design-related details, including network topology, cable diagrams, cabling techniques, power-plug connections and positions, cabling mechanisms for different chassis, PDU placement, and air conditioning and air circulation requirements.įor migration, switch interoperability is an important consideration.

Upgrade components (To meet the requirements of the support matrices).

This step helps you define, scale, and meet your migration goals: The process of SAN migration starts with preparation.

After migration is complete, you can implement continuous monitoring and optimization to identify and mitigate risk and tune the infrastructure to accommodate new projects and applications as the need arises. Operate and optimize: Perform the actual migration, move cables and chassis, and configure the new setup.This step will help the new SAN environment have enough flexibility to meet your needs longer. Identify any new additions and future requirements for the SAN fabric at this stage.

Plan and design: Identify migration options and create a migration strategy.Depending on migration method used, most of the configuration can be completed ahead of time. Prepare all device configurations (zone conversion, VSAN configuration, etc.) in advance and have them ready during the change window. Prepare or update the SAN and storage diagram to meet new requirements. Prepare a rollback procedure in case rollback is required. Identify critical servers, storage subsystems, and applications. Prepare: Analyze the current storage infrastructure, business requirements, and risks.Both vendors work together for a period of time before the old switches are removed in phases. Interoperate: New switches are connected to old switches using interoperate mode.The old switches are removed one by one while both SANs are running and serving traffic simultaneously and independently during the migration. New and existing servers and targets are attached to new switches. Cap and Grow: New switches are connected in a parallel topology to an existing third-party SAN.Rip and Replace: As the name suggests, with this approach you simply replace the old switches with new preconfigured switches.Generally, you can choose among three migration methods for SAN migration:
