• Each 4Gb, 8Gb, or 10Gb port is supported by a data buffer with a 16 credit base capacity (that is, 16 maximum sized frames).
• Longer distances can be spanned at full bandwidth on 1/2/4/8Gb or 10Gb ports by extending buffer credits to G_Ports, F_Ports and E_Ports
(per table above).
• Each 1/2/4/8Gb or 10Gb port on an I/O Blade can donate up to 15 of their 16 base buffer credits which a recipient port on the
Blade can borrow.
• The recipient port also loses a single base buffer credit in the process.
• Prerequisite minimum cable lengths apply as well.
