SRX5K-SPC-4-15-320 Juniper SRX5K Services Processing Card
Juniper SRX5K-SPC-4-15-320 Services Processing Card
High-Capacity SPC2 Services Processing Card for SRX5000 Series
The Juniper Networks SRX5K-SPC-4-15-320 Services Processing Card (SPC2) is a high-performance security processing module designed for Juniper SRX5400, SRX5600, and SRX5800 Services Gateways. Acting as the core engine for advanced security services, this SPC offloads CPU-intensive tasks from the control plane, enabling high-throughput, low-latency performance even in the most demanding network environments.
Equipped with 4 multi-core CPUs (15 cores each) and an impressive 320 GB of memory, the SRX5K-SPC-4-15-320 is engineered to handle massive session tables, complex firewall policies, and advanced threat detection at scale. It supports millions of concurrent sessions, making it ideal for service providers, large enterprises, and hyperscale data centers.
The SPC2 is purpose-built for deep packet inspection (DPI) and advanced security services, including firewall filtering, intrusion prevention (IPS), VPN encryption, antivirus, and application identification (AppSecure). Its parallel processing architecture distributes workloads efficiently across multiple cores, ensuring consistent performance for high-volume traffic and latency-sensitive applications.
Designed for scalability, the SRX5K-SPC-4-15-320 allows linear performance scaling as additional SPCs are installed within the chassis. It also supports N+1 redundancy in active/active configurations, ensuring uninterrupted security enforcement and seamless failover in mission-critical deployments.
With dynamic resource allocation, the SPC intelligently prioritizes processing power for critical traffic flows, optimizing performance across diverse applications. When integrated with high-capacity IOC and SCB modules, it enables the SRX5000 Series to achieve terabit-scale firewall and VPN throughput.
Fully integrated with Junos OS, the Juniper SRX5K-SPC-4-15-320 (SPC2) delivers a powerful, scalable, and reliable solution for organizations requiring next-generation security, advanced threat protection, and high-performance network processing.

FAQs:
Q1. How many SPC-4-15-320 cards can I install in an SRX5800?
The SRX5800 supports up to 11 slots for cards; depending on your IOC (Input/Output Card) requirements, you can scale up to multiple SPCs to reach your desired firewall throughput.
Q2. Is this card compatible with the newer SPC3?
Yes, the SRX5000 series supports "mixed mode" where SPC2 and SPC3 cards can coexist in the same chassis, though specific Junos versions and configuration rules apply to ensure balanced traffic distribution.
Q3. Does this card handle physical network ports?
No. The SPC is strictly for data processing. You must pair this with an IOC (Input/Output Card), such as the SRX5K-MPC, to provide the physical 10G, 40G, or 100G Ethernet ports.
Q4. Does the SPC-4-15-320 require a specific Switch Control Board?
To maximize the performance of the SPC2, it is typically paired with the SRX5K-SCB2 or SRX5K-SCB3 to ensure the backplane fabric can handle the data throughput.
Q5. What is the difference between this and the older SPC-2-10-40?
The "4-15-320" indicates 4 CPUs with 15 cores each and significantly higher memory (320GB), offering a massive increase in session capacity and processing speed over first-generation SPCs.
