About the PAN-QSFP-40G-SR4

The Palo Alto PAN-QSFP-40G-SR4 optical transceiver provides high density 40 Gigabit Ethernet connectivity for enterprise core firewall aggregation and data center backbone connections. Operating over four parallel optical lanes at 850 nanometers on multimode fibre, it supports link lengths up to 100 meters on OM3 and 150 meters on OM4 optical cabling.

Compatibility

Compatible with Palo Alto PA-3200 Series, PA-5200 Series, and PA-7000 Series firewalls equipped with QSFP+ ports. It supports native 40GbE fabric links as well as channelized 4x10GbE breakout mode configured via standard PAN-OS command line interface options.

How to identify a genuine unit

Constructed in a QSFP+ metallic casing with a beige or black pull tab release mechanism for port extraction. The manufacturing label displays Palo Alto Networks branding, part number PAN-QSFP-40G-SR4, individual serial number barcode, and optical laser safety warnings.

Buying used

Inspect the MPO internal optical guide pins and ferrule face with an MPO fiber scope to ensure no dust or scratches exist on any of the optical fiber lanes. Test on a QSFP+ firewall port to ensure all four optical lanes synchronize and report balanced optical power levels.

Works together

How the Palo Alto PAN-QSFP-40G-SR4 connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
