95P7644 - IBM 8Gb Fibre Channel Short-Wave SFP+ Transceiver

IBM 95P7644 is an 8Gb Fibre Channel short-wave SFP+ transceiver, a FRU for the 8Gb FC Mezzanine card in IBM System Storage N series controllers.

The IBM 95P7644 is a Small Form-factor Pluggable Plus (SFP+) optical transceiver module designed to provide 8Gb Fibre Channel short-wave connectivity. It is officially listed by IBM as a Field Replaceable Unit (FRU) intended for use with the 8Gb Fibre Channel Mezzanine card (feature #2030) installed in IBM System Storage N series controller modules, including the N3220 and N3240 platforms, as well as broader N series filer and gateway systems. The module enables Fibre Channel SAN connectivity by converting electrical signals from the storage controller's FC mezzanine card into optical signals for transmission over multimode fiber cabling. As a hot-swappable component, it allows service personnel to replace a failed transceiver without removing the entire FC adapter assembly, minimizing downtime in storage area network environments. This part is primarily used for maintenance, repair, and replacement of existing IBM N series storage hardware.

Per available IBM FRU documentation, this transceiver is validated for use with:

• IBM System Storage N3220 (2857-A12, A22)
• IBM System Storage N3240 (2857-A14, A24)
• IBM 8Gb Fibre Channel Mezzanine card (Feature #2030)
• IBM N series filer configurations requiring FC connectivity
• IBM N series gateway configurations (Feature Code 9551)
• IBM System Storage N7950T and related N7x00/N6x00 series (per IBM N series FRU parts listing)

Note: Compatibility is based on IBM's official N series FRU parts listing; some N series models with no on-board Fibre Channel ports (e.g., N3220/N3240 models A22/A24) require the FC mezzanine card and this SFP+ module to enable Fibre Channel functionality.

Q: What is IBM part number 95P7644?

A: It is an IBM Field Replaceable Unit (FRU) identified as an 8Gb Fibre Channel short-wave SFP+ transceiver module, used in IBM System Storage N series controllers.

Q: Which IBM storage systems use the 95P7644 transceiver?

A: According to IBM's official FRU parts listing, it is used with the 8Gb Fibre Channel Mezzanine card in N3220 and N3240 controllers, and appears in FRU tables for other N series filer and gateway systems such as the N7950T.

Q: Is 95P7644 hot-swappable?

A: SFP+ transceivers of this type are designed as hot-swappable components, allowing replacement without removing the entire Fibre Channel adapter assembly, consistent with IBM's standard FRU replacement approach for SFP modules.

Q: What speed does the 95P7644 support?

A: It is documented as an 8Gb Fibre Channel short-wave module; the associated FC 2030 mezzanine card it plugs into supports auto-negotiation across 1, 2, 4, or 8 Gbps Fibre Channel speeds.

Q: Is 95P7644 still available for purchase?

A: It appears primarily in legacy IBM N series FRU documentation and on refurbished-parts distributor sites, indicating it is likely an End-of-Sale part available mainly through the secondary/refurbished market.

Q: Does the 95P7644 require a special adapter card?

A: Yes, per IBM documentation this SFP+ module is intended for use specifically with the 8Gb Fibre Channel Mezzanine card (Feature #2030) installed in compatible N series controller modules.

Q: What connector and fiber type does 95P7644 use?

A: Exact connector and fiber specifications are not detailed in IBM's FRU listing for this specific part number, though short-wave 8Gb Fibre Channel SFP+ modules of this class typically use LC duplex connectors over multimode fiber.
