SuperBlade
Pass-Thru Module
1 Overview
The Supermicro SBM-25G-P10 Pass-Thru Module is designed for Supermicro SuperBlade
enclosures for high performance datacenter traffic application usage. It is compatible with
the SuperBlade 8U (SBE-820J), 6U (SBE-610J), and 4U (SBE-414E) enclosures. Up to four
modules can be used in the 8U or 6U enclosure, and up to two in the 4U enclosure.
The Pass-Thru module leverages the existing network infrastructure to provide direct network
connectivity between the blade servers and the external Top of Rack (ToR) switches using five
external QSFP28 ports. The module can support both 10G and 25G speed blade servers on
its internal ports. The five QSFP28 external ports can accept QSFP28 DAC, DAC breakout
cables and QSFP28 fiber transceiver modules for the external network connectivity.
The module provides a one-to-one connectivity from the internal blade server ports to the
external QSFP28 Ports.
