QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G

network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable

transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various

network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber.

QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a

server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to

10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an

SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector

that supports data rates up to 1 Gbps, but not 40 Gbps. GBIC modules have an SC duplex connector

and can be inserted into a GBIC port on a switch or a server. SFP (Small Form-factor Pluggable) is

another older type of connector that supports data rates up to 1 Gbps or 4 Gbps, but not 40 Gbps.

SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a

server. Reference: https://www.howtogeek.com/190014/virtualization-basics-understandingtechniques-and-fundamentals/ https://www.howtogeek.com/428483/what-is-end-to-end-
