What do the port states in the switchshow output of a Brocade Fibre Channel director or switch mean, and which of them point at the transceiver rather than the fabric?
The two SFP ports (F1/F2) of a Brocade ICX6450-C12-PD, licnesed for 10G, would not come up with either a Brocade 1000BASE-LR SFP (33211-100) or 10GBASE-SR moduls over a 5 m single-mode patch to an ICX6450-24P. show media saw the transceivers but the interface reported GigabitEthernet1/3/1 is down…
We are adding capacity to a small FC fabric and bought compatible 16G short-wave SFP+ from an optics supplier instead of paying the switch vendor price. The switch refuses them. Brocade G610, Fabric OS 9.x generic-coded 16G SWL SFP+, correct wavelength and reach according to the label Brocade-coded…
Running a small virtualization setup: two Proxmox 6 nodes and a target on FreeNAS 11.2. While the HBAs were connected to the target directly, everything ran for months without a single error. Put a used Brocade 200e between them to avoid crossing cables, and that's when it started. two Proxmox 6…
We are adding a G610 to an existing fabric and there is a box of non-Brocade 16G/32G FC SFP+ left over from another build. Before I plan any ports around them I put one into a spare port on the bench to see what the switch makes of it. Brocade G610, Gen 6 third-party 32G FC SFP+, no Brocade…
We inherited a pair of Connectrix DS-7720B (Brocade G720) for a new fabric, and I haven't got anywhere near zoning yet, because not one of the double density ports will come up. Every single one of them says the same thing in switchshow: What is in the rack: Connectrix DS-7720B / Brocade G720…
An operator asked about the practical behaviour of Brocade equipment with third-party SFP/SFP+ optics. Experience shared on NANOG: Foundry-heritage platforms (FastIron, NetIron, ICX including ICX7750) generally bring up any MSA-coded module, but the optical-monitor (DDM) function may be unavailable…
The poster wanted a cheap 10G link between servers with Intel X520-DA2 NICs and an HP switch and worried that a direct-attach cable is coded either for Intel or for HP but not both. A respondent shared that two X520-DA2 cards would not link directly over a DAC in their case, but a Dell DAC…
