NFX250-S2 Overview
NFX250-S2 32GB Compute Tier
NFX250-S2 is the higher-capacity NFX250 profile with 32GB RAM and a 400GB SSD. It retains the family six-core CPU and mixed copper/SFP/SFP+ interfaces while providing materially more guest-resource headroom than the 16GB S1 models.
VNF capacity evidence
Juniper's NextGen prerequisites list 22GB of memory available for VNF use for S2 in the referenced Junos OS 19.1R1 table, compared with 6GB for NFX250-S1 and NFX250-S1E. Another current guide lists up to 24GB of hugepages in applicable compute/hybrid/custom contexts. Use the table matching the installed software and selected performance mode.
Storage planning
The 400GB SSD supports a larger image and log footprint, but capacity still requires allocation for platform software, VNF images, snapshots, updates and operational reserve. Document image provenance and cleanup policy; storage size does not prove a VNF is supported.
Shared interface architecture
S2 uses the NFX250 set of eight 1GbE access ports, two flexible 1GbE RJ-45 ports, two SFP and two SFP+ uplinks plus management and console interfaces. Verify optics and intended SR-IOV/VirtIO mapping against Juniper documentation and the exact release.
Receiving and workload test
Confirm the 32GB/400GB inventory, AC input, front-to-back airflow, Junos/JDM version and selected mode. Before acceptance, compare measured available memory/hugepages with the design and test the intended VNF chain, port mapping, management reachability and rollback process.
Official evidence: Juniper NFX250-S2 model specification, Juniper S2 VNF resource availability, Juniper hugepage and memory allocation and Juniper NFX250 ports, power and airflow.
