Fibre Channel کی رفتاریں
ہماری ٹیم ترجمے پر کام کر رہی ہے۔ یہ مضمون عارضی طور پر اردو میں دستیاب نہیں ہے، اس لیے اسے انگریزی میں دکھایا جا رہا ہے۔
Fibre Channel rates are written with a GFC suffix (gigabaud Fibre Channel). Each generation roughly doubles throughput while keeping backward compatibility with a few prior generations.
Generations
| Rate | Line coding | Typical module |
|---|---|---|
| 4GFC | 8b/10b | SFP+ |
| 8GFC | 8b/10b | SFP+ |
| 16GFC | 64b/66b | SFP+ |
| 32GFC | 64b/66b | SFP28 |
| 64GFC | 64b/66b | SFP-DD / SFP56 |
| 128GFC | 4×32GFC | QSFP28 |
Backward compatibility
A port usually negotiates down to older generations — for example a 32GFC port interoperating with 16GFC and 8GFC equipment. This makes staged upgrades practical inside an existing SAN.
Media designation
FC optics are labelled by wave type and reach: SW for 850 nm multi-mode short reaches and LW for 1310 nm single-mode long reaches, similar in spirit to the Ethernet interface names.
