On an Intel S2600WFT board the X722 10GbE SFP+ controller (rev 09, NVM 3.31 0x80000d31 1.1767.0) refused ethtool -m with Cannot get module EEPROM information: Invalid argument, and the kernel logged Module EEPROM memory read not supported. Please update the NVM image. The behaviour was identical…
The poster wanted to verify whether an HPE StorageWorks 81B 8 Gb Fibre Channel HBA (AP769-60001) fitted with an AJ716B SFP could be used in an HPE ProLiant DL380 Gen10 server (P02464-B21) and asked for a tool where part numbers can be entered to get a compatibility verdict. No error had occurred…
The poster wanted a cheap 10G link between servers with Intel X520-DA2 NICs and an HP switch and worried that a direct-attach cable is coded either for Intel or for HP but not both. A respondent shared that two X520-DA2 cards would not link directly over a DAC in their case, but a Dell DAC…
The poster, validating their product against Cisco Nexus 9000 switches (a Nexus C9332D-GX2B chassis), is blocked by bug CSCwo18785: configuring 200G on a QSFP-200G DAC fails with 'ERROR: The transceiver doesn't support this speed'. The cable is a Mellanox MCP1650-H002E26 200GbE DAC; connected…
The poster planned to install an Intel X520 adapter (Cisco PID N2XX-AIPCI01) into a Cisco UCS C240 server and use Cisco SFP-10G-SR or SFP-10G-LR transceivers, and asked whether the combination has compatibility problems. A later reader asked whether the Cisco SFP-H10GB-CU3M= twinax cable would work…
