HP compatible S0K91A Description
EdgeOptic's S0K91A compatible is an HPE-coded version of the EdgeOptic 25G-SFP28-100 25GBASE-SR SFP28 transceiver, built as a drop-in match for HPE's MSA 25Gb SFP28 Short Range 4-pack iSCSI Transceiver.
HPE markets the S0K91A as the "HPE MSA 25Gb SFP28 Short Range 4-pack iSCSI Transceiver," ordered as a set of four modules. It is HPE's 25GbE iSCSI SFP option for MSA Gen7 storage arrays.
The S0K91A is a distinct SFP28 part from HPE's 10Gb C8R25B SFP+ Short Range iSCSI Transceiver used on the same MSA Gen7 platform family. Confirm the SFP28 form factor and rate against the array's MSA QuickSpecs before ordering, since the module will not physically fit an SFP+ cage.
The module uses an 850 nm VCSEL transmitter and a PIN photodiode receiver over duplex OM3, OM4, or OM5 multimode fiber through an LC/UPC connector pair, reaching 100 m on OM4 or 70 m on OM3 within a 5.3 dB average link budget. Average launch power runs from −5 dBm to +2.4 dBm per lane, and average receiver sensitivity runs from −10.3 dBm to +2.4 dBm per lane. Operating range is 0°C to 70°C at 0.3 W max from a single 3.3 V supply, meeting SFF-8432, SFF-8431, SFF-8472, and SFP28 MSA specifications with RoHS and CE compliance.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the S0K91A compatible ships with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.
Frequently Asked Questions
What HPE MSA storage arrays use the S0K91A transceiver?
HPE's MSA Gen7 QuickSpecs name the S0K91A as the 25GbE iSCSI SFP option for the MSA 1060, 2060, and 2062 storage arrays. HPE's MSA 2070/2072 spare-parts documentation also lists a 25 Gb transceiver option for those Gen7 controllers, though that pairing rests on thinner published detail than the 1060/2060/2062 line. Check the QuickSpecs sheet for the specific array and controller firmware before ordering.
Can an HPE MSA Gen7 array use both 10Gb and 25Gb iSCSI transceivers?
HPE's MSA 2070/2072 spare-parts documentation states that a Gen7 array can support either 10 Gb or 25 Gb iSCSI transceivers. Check HPE's MSA QuickSpecs for the specific array and controller firmware to confirm per-controller mixing rules before combining the 25Gb S0K91A with a 10Gb SFP+ option such as the C8R25B.
