FlexibleLOM is HPE's mezzanine LOM format for ProLiant rack servers: the card sits on its own connector, so its ports never cost a PCIe slot. One fits per server, and swapping it later changes port speed or media.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003e817747-001, 840139-001 (option 817749-B21)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eController\u003c\/th\u003e\n\u003ctd\u003eMellanox ConnectX-4 Lx (MCX4121A-ACFT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePorts\u003c\/th\u003e\n\u003ctd\u003e2x 10\/25GbE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnector\u003c\/th\u003e\n\u003ctd\u003eSFP28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm factor\u003c\/th\u003e\n\u003ctd\u003eFlexibleLOM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost interface\u003c\/th\u003e\n\u003ctd\u003ePCIe 3.0 x8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eRefurbished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e180-day\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe 640FLR-SFP28 seats on the FlexibleLOM connector only and takes the one FlexibleLOM position the server has. It is the fastest Ethernet FlexibleLOM HPE lists for Gen10, where the slot is rated for NICs up to 25GbE. If you run it on the DL580 Gen9, Wake-on-LAN through a FlexibleLOM is unsupported. Gen10 Plus servers moved to an OCP 3.0 slot and take no FlexibleLOM card. SFP28 optics and DACs are sold separately; match them to the switch side.

Versus the 562FLR-SFP+, it buys 2.5 times the bandwidth per port in the same slot. For InfiniBand or 40\/50GbE, look at the 544+FLR-QSFP or 547FLR-QSFP. The trap: SFP28 at 25GbE needs 25G-rated DACs or optics; 10G SFP+ optics hold the port at 10GbE.\u003c\/p\u003e\u003cp\u003eEvery part we sell is tested and covered by our 180-day warranty.
