Upgrade
* This feature is already included in the bundle.
With Brocade's Dynamic Ports on Demand (DPOD) feature, ports are licensed in one of two methods: as
they come online or as selected by the administrator. With the 16 Gb SAN switch, the first 12 ports
reporting (on a first-come, first-served basis) on boot-up are assigned licenses. These 12 ports can be any
combination of external or internal Fibre Channel (FC) ports. After all port licenses have been assigned, you
can manually move those licenses from one port to another. Because this is dynamic, no defined ports are
reserved except ports 0 and 29. The 24-port 16 Gb SAN switches have the same behavior; the only
difference is the number of ports, which is 24.
Table 5 shows the total number of port licenses on the switch after applying compatible port upgrades.
Note: A maximum of one upgrade of each type (one Upgrade 1 and one Upgrade 2) is supported per one
switch module. Upgrade 1 and Upgrade 2 can be applied independently of each other.
Table 5. Ports on Demand upgrades
Ports on Demand upgrade
Included with base
Upgrade 1, 88Y6382 only (adds 12 port licenses)
Upgrade 2, 88Y6386 only (adds 24 port licenses)
Both Upgrade 1, 88Y6382 and Upgrade 2,
88Y6386 (add 36 port licenses)
* With the dual-port FC adapters installed in compute nodes, up to 34 ports (14 internal, 20 external) can be utilized. The
remaining 14 internal ports require use of the 4-port FC adapters in the server's ITE.
Benefits
The switches offer the following key benefits:
Exceptional price/performance for growing SAN workloads
The FC5022 16 Gbps switch delivers exceptional price/performance for growing SAN workloads
through a combination of market-leading 1600 MB/sec throughput per port and an affordable high-
density, 12-port to 48-port form factor.
Enhanced server performance while using 16 Gb Gen 5 FC technology
Using 16 Gb FC adapters on the server and the FC5022 modules can help achieve the following
server enhancements, even if 8 Gb FC storage is used:
Up to 30-50% better virtual machine density and higher number of concurrent users due to
increased storage bandwidth
