Port group in Brocade 6510 Switch

In any Cisco SAN switch each port bandwidth is shared with a port group consists of 12 port , for Brocade 6510 is the same concept is applied there ? I need to dedicate a port speed for few ports and I need more information.

Re: Port group in Brocade 6510 Switch

Hi Joe,

The DS-6510B has 48 ports, by default 24 ports are enabled, and 24 can be enabled by "port on demand license". All ports can do 16 GB/s.

You should be able to find the hardware manual and the Product Support Bulletin here:

Regards,

Thanks, I mean the port group bandwidth not the total number of ports

Hi Joe,

Yes I understood that. So all ports do 16 GB/S.

Where you able to download the Product Support Bulletin?

Re: Port group in Brocade 6510 Switch

Just to put Ed's comment in different words in case that helps. Brocade and Cisco take a different approach to providing bandwidth to switch ports. Cisco goes with the idea (which is probably right most of the time) that you will never drive ALL the ports in a switch (or in a given set of ports) full out at the same time. Brocade builds on the assumption that you might.

On most (maybe all, but definitely including all the current departmental switches like the 6510 and 6520) Brocade switches you can drive every port at full 16G at the same time (assuming you are using 16G SFPs).

All ports do 16g, so I dedicate the throughput for the 48 ports so its not being shared with any other ports. checked the documents and found that 6510 comes with condor3 ASIC 6*8 port in total

Thanks, so driving each port to 16G wont affect the others as in MDSs there is a limited bandwidth per port group and driving one port to 8G will impact the rest of ports so this seems to be different here ..

Re: Port group in Brocade 6510 Switch

Just to clarify further . in cisco the port groups have fixed amount of bandwidth , this port group shares common resources from an assigned pool of allocated bandwidth , so that cannot be applied on this brocade ?

Re: Port group in Brocade 6510 Switch

That  correct. You could drive every port on the entire switch at 16G and the only thing you would really need to worry about would be any ISLs involved :-)

Mind you, if you were going to run EVERY port that busy you might need to reconsider your entire environment *lol*

Re: Port group in Brocade 6510 Switch

Why I have to consider the ISLs if the ports cant run 16g individually ? lol why to reconsider its a small env
