juniper QFX Series QFX10002-36Q
The Juniper QFX10002-36Q is a 2U deep-buffer fixed spine and datacenter interconnect (DCI) switch powered by custom Juniper Q5 ASICs. Delivering 36 ports of 40GbE QSFP+ (or 12 ports of 100GbE QSFP28) with up to 100 ms of deep packet buffer per port, the QFX10002-36Q prevents packet drops during heavy microbursts and bursty storage traffic. Resellers target this model for enterprise organizations requiring deep buffers and large routing table capacities without buying a full chassis.

Works together
How the juniper QFX Series QFX10002-36Q connects to servers, storage and the network: 3 ways, with the parts and products on each path.
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.
