About the PAN-QSFP28-100G-SR4

The Palo Alto PAN-QSFP28-100G-SR4 optical transceiver delivers ultra high throughput 100 Gigabit Ethernet connectivity for hyperscale data center firewalls and high performance security fabrics. Operating across four parallel 25Gbps optical channels at 850 nanometers on multimode fibre, it provides massive throughput with low latency.

Compatibility

Compatible with Palo Alto PA-3440, PA-5260, PA-5280, PA-5400 Series, and PA-7000 Series firewalls equipped with QSFP28 ports. It requires host Forward Error Correction (RS-FEC) enabled on switch ports to ensure IEEE 802.3bm signal integrity standards under PAN-OS.

How to identify a genuine unit

Housed in a QSFP28 metallic shell featuring a beige or black pull tab extraction handle for dense port arrays. The top label bears the Palo Alto Networks logo, part number PAN-QSFP28-100G-SR4, individual serial number barcode, and international regulatory safety markings.

Buying used

Inspect the MPO optical ferrule interface under high magnification to confirm that none of the optical channels are scratched or obstructed by debris. Verify in a PA-Series firewall that RS-FEC synchronizes properly and that all four optical channels show balanced receive power levels.

Works together

How the Palo Alto PAN-QSFP28-100G-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.

Storage

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.
