InfiniBand 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۔
InfiniBand names each generation with a short code. The code is a per-lane rate; the port bandwidth is that rate times the link width (usually ×4).
Generations (per lane)
| Generation | Per lane | ×4 port |
|---|---|---|
| SDR | 2.5 Gb/s | 10 Gb/s |
| DDR | 5 Gb/s | 20 Gb/s |
| QDR | 10 Gb/s | 40 Gb/s |
| FDR | ~14 Gb/s | ~56 Gb/s |
| EDR | 25 Gb/s | 100 Gb/s |
| HDR | 50 Gb/s | 200 Gb/s |
| NDR | 100 Gb/s | 400 Gb/s |
Modules
Because the common port is ×4, InfiniBand rides QSFP-family optics: EDR on QSFP28, HDR on QSFP56, and NDR on OSFP or QSFP112. The form factor follows the per-lane rate and lane count, just as it does for Ethernet.
Early generations (SDR–QDR) used 8b/10b line coding; FDR and later moved to 64b/66b, which is why FDR's per-lane figure is about 14 rather than 12.
