HP compatible C8R23B Description
HPE C8R23B is an 8Gb Short Wave Fibre Channel SFP module for HPE MSA storage platforms (MSA 1040, MSA 1050, MSA 2040, MSA 2050 and HPE 3PAR legacy arrays). The HPE datasheet classifies C8R23B as an SFP rather than an SFP+ part, reflecting its targeted use in MSA storage controller FC host ports at 8GFC. EdgeOptic's compatible C8R23B carries MSA-recognized EEPROM coding so the controller firmware accepts the optic without flagging a third-party warning on the FC host port.
Protocol is 8GFC per FC-PI-4 (T11.3 INCITS 424-2007) at 8.5 Gbps, with backward rate support at 4.25 and 2.125 Gbps. Transmit uses an 850 nm VCSEL and the receive side uses an 850 nm PIN photodiode. The FC-PI-4 link budget of approximately 8.0 dB delivers 150 m OM3, 190 m OM4, 50 m OM2 and 21 m OM1 reach at the full 8GFC rate. Mechanical and electrical characteristics follow the SFP MSA (SFF-8074i). The duplex LC connector, 0 to 70 C commercial temperature range and SFF-8472 DDM/DOM instrumentation make the module a drop-in for MSA 8GFC host ports. C8R23B is the MSA counterpart to C8R25B; the two are distinct SKUs within the same HPE FC optics line and should be matched to the specific array SKU called out in the HPE quickspecs.
C8R23B is a Brocade-OEM optic at the silicon level but is coded for MSA storage recognition, which is why MSA arrays accept it where a Brocade switch-side module would also be required. On the fabric side, pair with B-series shortwave modules such as AJ716B on the matching Brocade FC switch ports; this keeps the full SAN path, from MSA host port to Brocade ISL to server HBA, running on HPE-qualified optics end to end. MSA controller firmware reads the SFP vendor ID during port initialization and will flag non-MSA-coded optics in the event log; EdgeOptic's C8R23B carries the MSA vendor ID to avoid that flag. For MSA firmware compatibility details, mixed 3PAR and MSA refresh planning, or bulk orders for storage fleet refresh projects, please contact our sales team.
Frequently Asked Questions
Which HPE MSA arrays accept C8R23B?
C8R23B is coded for MSA storage platforms including MSA 1040, MSA 1050, MSA 2040 and MSA 2050, plus legacy 3PAR arrays that share the same MSA FC optic qualification. It lands in the Fibre Channel host ports on the storage controller.
Is C8R23B an SFP or SFP+ module?
HPE classifies C8R23B as an SFP in the MSA product documentation. The electrical and optical interface follows the SFP MSA while the module operates at the 8GFC rate, which is the common convention for MSA 8G host-port optics.
What is the difference between C8R23B and C8R25B?
C8R23B and C8R25B are separate HPE SKUs within the same MSA 8G Fibre Channel optic family, each paired to specific array firmware revisions. Match the SKU to the array quickspec rather than substituting across the two part numbers.
