G620 FOS 8.x and 4Gb in the fabric

Some new G620 (IBM 8960-F64) switches will be joined to existing fabrics once the existing swtiches have a compatible FOS running on them. SFPs are all 32Gb, including the 16-port 128Gb QSFP option.

 

Brocade Encrpytion Switch (7.1.1.b  -->  go to 7.4.1)

Brocade 5100 (7.1.1b --> go to 7.4.2a)

Brocade 300 (2 @ 7.4.1a --> go to 7.4.2a)

 

Customer states that he read there can be no 4Gb devices in the fabric but I have yet to find that anywhere. What is there to look out for when adding in these G620s?

@KAugustC

 

Brocade G620, support three rate SFP

 

32/16/8 Gb

 

or

 

16/8/4 Gb

 

and work as wel at 4Gb

 

in few word, if you want to connect 4gb Device whatever Storage or HBA, you need to use 16Gb SFP and set the port at 4Gb

You can connect 4G end devices (e.g. HBAs and storage ports) to the fabric with 6gen switches, as stated by Antonio.

But you can NOT have any 4G switches in the same fabric with 6gen switches.

So an 8Gb switch with some 4Gb host/storage connections is allowed? Obviously the ISLs would be 8Gb.

Correct, end devices running at 4G work but not 4G switches (or 4G switches in AG mode)  since they are on FOS 6.x.

Below is the quote from FOS 8.0.2c RN
