Bahasa Melayu Storage protocols & optics
Đội ngũ của chúng tôi đang thực hiện bản dịch. Bài viết này tạm thời chưa có bản tiếng Việt và đang được hiển thị bằng tiếng Anh.
Several protocols move storage traffic, and each pairs with a family of optics.
The main protocols
| Protocol | Runs over | Typical optics |
|---|---|---|
| Fibre Channel | dedicated FC fabric | FC SFP+/SFP28 (SW/LW) |
| FCoE | lossless Ethernet | Ethernet 10/25G |
| iSCSI | TCP/IP Ethernet | Ethernet 10/25G |
| NVMe/TCP | TCP/IP Ethernet | Ethernet 25/100G |
| NVMe-oF (RoCE) | lossless Ethernet | Ethernet 25/100G |
| NVMe-oF (FC) | FC fabric | FC SFP28/QSFP |
FC vs Ethernet optics
- Fibre Channel modules are FC-rated and labelled SW (850 nm MMF) or LW (1310 nm SMF); rates are the GFC generations in Fibre Channel speeds.
- Ethernet storage uses standard Ethernet interfaces such as
25GBASE-SRor100GBASE-LR4(see Optical Ethernet interfaces).
NVMe over Fabrics
NVMe-oF carries the low-overhead NVMe protocol across a network — over Fibre Channel, over RoCE on lossless Ethernet, or over plain TCP — to reach flash arrays with minimal added latency.
A module built for one fabric reports rates and interfaces accordingly; CodingBox shows those fields so you can confirm a transceiver suits the storage network.
