Introduction
If you select a Brocade SAN switch, do not only focus on its speed. You need to consider multiple factors, because a new-generation switch can bring real benefits only when it works well with your existing SAN and other hardware.
Newer Fibre Channel platforms offer faster speed and shorter delay. Even so, you cannot get these performance gains unless your connected servers, HBAs and storage arrays can also work at this level.
For this reason, buyers should not rely only on advertised speed. If you want stable switch performance in a real-world SAN, you also need to evaluate port capacity, device compatibility, transceivers, software support and fabric design.
How to Choose a Brocade SAN Switch
Performance and Port Planning for a Brocade SAN Switch
When you plan a SAN upgrade, do not pick a switch model first. Start with your actual workload instead. If you choose a Brocade switch, it must provide enough Fibre Channel bandwidth for your current storage traffic. It should also support new servers, faster storage and future expansion.
Port count matters equally. A switch may offer plenty of physical ports, yet some ports may stay inactive in its initial setup. If you want a proper selection, buyers need to evaluate usable ports, supported FC speeds, port licensing, transceivers and uplink requirements as a whole.
Match Fibre Channel Speed to the Existing SAN
When you choose a SAN switch, check its transfer speed first. Brocade switches support multiple Fibre Channel speeds. New models go up to 64G. Some units support automatic speed negotiation.
If you connect a new Brocade switch to older HBAs or storage arrays, auto negotiation brings great convenience. When peer devices run at lower speeds, the switch does not force all ports to maximum speed.
Check your full data link carefully. You get real bandwidth improvement only when servers, HBAs, storage controllers and transceivers all support high speed FC. If only the switch supports high speed, performance gains stay limited.
If your SAN runs flash or NVMe storage, you should also watch latency. According to Broadcom, its 64G switches have lower latency than earlier generations. They are built for high speed storage workloads.
Even with lower switch latency, applications will not speed up automatically. Final performance depends on storage arrays, HBAs, host workloads and fabric design.
Plan Ports for Hosts, Storage, and Expansion
If you plan ports for your SAN, you should calculate current demands and reserve expansion space. You also need to check hardware-related details when you select a rack-mount switch.
In a Fibre Channel network, ports serve different jobs. They connect servers and storage. They also support switch-to-switch links and redundant paths. If you will add more devices later, you should reserve extra port capacity.
When you calculate port needs, cover current connections first and leave room for growth. It is less risky than choosing a switch with nearly full ports.
If rack space is tight, a rack-mount switch works well. Yet you should not only look at its size. You also need to check airflow, power supplies, cable space and service clearance.
If you place the switch in a dense rack, these details will influence later maintenance and cooling.
Understand Ports on Demand Before Buying
If you use the Ports on Demand (PoD) function for Brocade switches, you must check platform rules and related costs. A low hardware price does not mean a low total cost.
Ports on Demand (PoD) is Brocade’s port-expansion feature. It lets users unlock extra ports through software-license upgrades. It is an optional license only for certain models, not standard equipment. It fits SAN environments with gradual growth, and you may activate only required ports at launch.
PoD port limits, license types and activation rules differ across switch models.
Before purchase, confirm active ports in quotations, hardware port capacity, available PoD licenses, upgradable physical interfaces, extra-license cost, and whether activation can run without traffic disruption.
When you compare supplier quotes, do not focus only on hardware price. Calculate total cost including licenses and transceivers.
SFP Port and Transceiver Selection
Full-compatibility matching is required for SFP-series transceivers on Brocade SAN switches. Official documents deserve your careful review, especially for third-party optical modules under consideration.
Optical links send data between SAN devices with fibers and transceivers. They are very important for SAN design. Switches with SFP ports connect servers and storage using transceivers. Transceivers must match speed, fiber type, distance and interface standards.
Some Brocade switches support SFP-DD interfaces with extra licenses. They save rack space but cannot take the place of SFP+. All hardware and settings need to work well together.
Read the vendor’s compatibility notes before you buy transceivers. The interface type alone cannot guarantee good performance.
For third-party transceivers, check vendor support, firmware fit, warranty and technical services.
Build a SAN Fabric That Can Scale
When you build a scalable SAN fabric, do not set ISL links only by the bandwidth shown on hardware specs. Match ISL capacity to your real world traffic and network design instead.
ISL, short for Inter Switch Link, connects separate SAN switches and enables storage data exchange across the whole network. Unlike regular switches that mainly focus on throughput and port numbers, SAN switches require extra checks. Key items include system redundancy, ISL connections and traffic paths. Multiple ISLs can operate as a group. This combination boosts total bandwidth and improves the network’s ability to handle device failures. Broadcom’s 64G platforms can hit 512Gb/s, and its 32G platforms can reach 256Gb/s. Even with these figures, such top speed values cannot serve as direct configuration rules.
Your actual traffic and network planning should guide ISL capacity choices. Scale up capacity as traffic grows, and avoid unnecessary extra links under light load conditions. For a core edge setup, place priority on high traffic paths during ISL deployment planning, rather than adding links simply based on a switch’s maximum bandwidth.
Check Software, Monitoring, and Licensing
Hardware parameters are not the only reference for Brocade SAN-switch selection. Carry out full evaluation on software functions, licenses and support services against real-world needs before placing your order.
Hardware specs cannot tell the whole story. Software features also change total purchase cost and how admins manage the SAN. Brocade switches run on Fabric OS. Some functions like Fabric Vision monitoring, ISL Trunking and PoD need extra licenses. Judge them by your real business needs.
Before you place an order, check OS version, function licenses, port licenses, monitoring needs, firmware access, software service time and technical-support scope.
Compare hardware and software costs together to judge quotations correctly.
Assess Product Power, Cooling and Total Costs Before You Pick a Specific Switch
When choosing Fibre-Channel switches, look beyond purchase price. Evaluate power, cooling and expansion costs to match present and future business needs.
Data-center switches create power costs and heat. Broadcom lists 349W for its 64G 1U model and 205W for 32G 1U model1. Real power use changes with settings, transceivers and workloads.
Many switches working together increase cooling demands. Total cost includes hardware, licenses, optics, support, power, cooling and future expansion.
Do not chase top-level performance blindly. Pick switches that fit current work and support later upgrades.
Brocade G720: A Practical Choice for SAN Upgrades
The buying factors above can also be applied to a specific product. The Brocade G720 is designed for enterprise SAN environments that need high port density, flexible expansion, and support for modern storage workloads.
Performance and Port Capacity
The Brocade BR-G720-48-32G-R provides 48 active 32Gbps SFP+ ports. The ports also support 64Gbps Fibre Channel, with auto-sensing for 8G, 16G, 32G, and 64G connections.
This makes the switch suitable for mixed-speed SAN environments. If higher-speed devices are added later, the existing infrastructure can support the upgrade.
The switch also supports NVMe and all-flash storage. It can therefore be considered when storage performance is becoming a key requirement.
Port Expansion and Rack Deployment
Port planning is another factor to consider. The G720 supports Ports on Demand (PoD), so port capacity can be increased as SAN requirements grow.
If the initial deployment does not require full capacity, buyers can start with the required ports. Additional capacity can be added later through the applicable licenses.
The 2U rack-mount design provides high port density in a standard data center rack. This can be useful when rack space and cable management are important.
Connectivity and Management
The G720 uses SFP+ connectivity for Fibre Channel devices. Before ordering, buyers should confirm the required transceivers. The FC speed, fiber type, and transmission distance should match the connected equipment.
For SAN management, the switch runs Brocade Fabric OS. Management options include SANnav, CLI, REST API, and SNMP.
If advanced monitoring is required, buyers should also check the necessary software licenses. This helps avoid unexpected costs after purchase.

When Does the G720 Make Sense?
The G720 is a practical option when an enterprise needs more SAN capacity without changing its overall architecture.
It can be a good fit if the current environment uses 32G Fibre Channel and higher-speed storage is planned. It is also worth considering when more ports are needed for servers, storage arrays, or future expansion.
If the current SAN already has enough capacity, an immediate upgrade may not be necessary. In that case, buyers should first review current traffic, port usage, and expected growth.
For buyers, the key is to match the switch with the actual SAN plan. Port capacity, FC speed, expansion options, compatibility, and software costs should all be checked before purchase.
