Juniper SRX Models Comparison: 5400 vs 5600 vs 5800

If you are in the market for high-performance Juniper SRX firewall equipment, this Juniper SRX models comparison will help you figure out which gateway model — between the SRX5400, the SRX5600 and the SRX5800 — will best fit your needs. The pre-owned Juniper SRX Series provides security for any size network for enterprises, service providers and data centers. The SRX Series also offers superior switching and routing capability, reducing the number of switches and routers you’ll need in order to operate.

Similarities Between SRX5400, SRX5600 and SRX5800 Gateways

The Juniper Networks SRX5000 gateway lineup includes three high-performance security models: the Juniper SRX5400, the SRX5600 and the SRX5800. Compared with the rest of the SRX Series, it’s clear these gateways are designed for high-intensity service providers and data center applications.

The SRX Series services gateways all feature a modular chassis, allowing for complete customization with various types of line cards. You can customize the configuration primarily using Switch Control Boards (SCBs), Services Processing Cards (SPCs), I/O cards (IOCs) and Flex IOCs.

The Juniper SRX firewall provides a flexible option that makes scaling your network easy. With a wide range of compatible line cards — which we’ll get into later — you can replace your current line cards with higher-performing ones to avoid replacing the whole chassis.

And when you briefly scan the specifications, it can look like these three models are essentially the same. But our Juniper SRX models comparison breaks down the biggest differences between them.

Take the number of line card slots, for example. The larger the device is, the more slots it contains. In addition, not every Juniper SRX supports the same types of cards. And on top of that, not all line cards are compatible with one another. As you’ll see, there’s a lot of factors to consider with these devices.

The biggest factor to consider when comparing SRX5400 vs SRX5600 vs SRX5800 devices is size, as that determines the number of line card slots that are available on each device. The smallest of these three is the Juniper SRX5400, at 5 rack units (RU) with the largest being the SRX5800 at 16 RU.

As we dive deeper into the Juniper SRX models comparison, we put the various models side-by-side for a better evaluation. By the time you’ve finished this page, you’ll quickly be able to spot the differences between the SRX5400 vs SRX5600, the SRX5600 vs SRX5800 and the SRX5400 vs SRX5800.

Juniper SRX5400 Specifications

As the smallest of these three Juniper gateways, the Juniper SRX5400 measures 5 RU in size, which means you can fit up to 8 Juniper SRX5400 Series services gateways in one full-sized rack.

 

When it comes to security, the SRX5400 firewall performance is 270 Gbps with an IPS performance of 230 Gbps. This model also supports up to 90 million concurrent sessions with 1.75 million new sessions.

The Juniper SRX5400, supports the following SCBs:

  • SRX5K-SCB
  • SRX5K-SCBE
  • SRX5K-SCB3

Note, however, that the Juniper SRX5400 does not support all I/O cards, specifically Flex IOCs, so if you know you’ll need to use Flex IOCs, you’ll have to opt for either SRX5600 or SRX5800 gateways.

The QFX5400 does, however, support Modular Port Concentrators (MPCs), which operate similarly to Flex IOCs, as they both increase the number of available physical interface ports for connecting to a network. The difference is that MPCs support Modular Interface Card (MIC) slots, whereas Flex IOCs support port modules, instead. The Juniper SRX5400 supports the following MPCs:

  • SRX5K-MPC
  • SRX5K-MPC3-40G10G
  • SRX5K-MPC3-100G10G

And as for the supported SPCs and IOCs, the SRX5400 supports the SRX5K-SPC-4-15-320 and SRX5K-SPC3 Services Processing Cards and the SRX5K-IOC4-10G and SRX5K-IOC4-MRAT Input Output Cards.

Line Card Specifications

If it’s not clear already, each Juniper SRX modular chassis is compatible with a wide variety of line cards. However, the number of line cards supported on each SRX chassis varies significantly. And if you’re in the market to buy SRX devices, it’s extremely important you choose a chassis that will suit your needs.

As can be expected, the smaller of the three, the SRX5400, has the fewest number of line card slots, while the largest, the SRX5800, has the most. Below is a more specific breakdown of the number of slots:

  • The SRX5400 has four total line card slots, but one is a dedicated SCB slot
  • The SRX5600 has eight line card slots, but two of them are dedicated for SCBs
  • The SRX5800 has 14 line card slots, but two of them are dedicated for SCBs

Regardless of which devices you use, you must fill all of the line card slots. If you don’t need every slot or don’t have enough modules available, you must install blank panels in all unused line card slots.

This ensures that any empty slots are blocked, which allows the cooled air generated by the system’s fans to properly circulate and regulate the temperature so the chassis can operate at peak performance.

Switch Control Boards (SCBs)

The SCB is responsible for chassis management, switch plane and control plane functions. It also serves as a carrier for the Routing Engine, which is why every SCB supported on the SRX series includes a routing engine slot. The Juniper SRX5400 has only one dedicated SCB slot. However, the other two Juniper SRX Series gateways, the SRX5600 and SRX5800, have two dedicated SCB slots.

The biggest difference between the SCBs supported on the SRX Series is the throughput, or maximum capacity. The SRX5K-SCB has the lowest throughput and the SRX5K-SCB4, the newest SCB, has the highest, which is why it’s only compatible with the higher-performing SRX5600 and SRX5800 chassis

Service Processing Cards (SPCs)

With your Juniper SRX Series gateway support a wide variety of SPCs. These line cards offer the processing power needed to run firewall, IPsec and IDP services. The SPC, or more specifically, the Services Processing Units (SPUs) inside the SPC, is responsible for applying those services.

Every Juniper SRX gateway must have at least one SPC installed, but you have the option to add more SPCs for increased processing throughput. To learn which SPCs are compatible with each SRX Series gateway, refer to the SRX5400, SRX5600 and SRX5800 specifications above.

Below are the specifications for SPCs available on SRX Series devices:

  • SRX5K-SPC-2-10-40: service processing card that contains two services processing units and a processor subsystem that has a 1.2-GHz CPU and 1GB of SDRAM
  • SRX5K-SPC-4-15-320: service processing card that contains four services processing units and a processor subsystem that has a 1.2-GHz CPU and 1GB of SDRAM
  • SRX5K-SPC3: service processing card that contains two services processing units and a processor subsystem that has a 2.3-GHz CPU and two 128 GB solid state drives

I/O Cards (IOCs)

I/O Cards (IOCs) are another type of line card available for SRX gateways. They provide physical network connections via Ethernet ports. Each I/O is configured with different types of Ethernet ports, which makes it easy to customize SRX Series chassis to the exact specifications you require.

Below are the specifications for the I/O cards available for SRX Series Devices:

  • SRX5K-40GE-SFP: fixed-configuration IOC with 40 SFP ports that support up to 1G Ethernet
  • SRX5K-4XGE-XFP: fixed-configuration IOC with four XFP ports that support up to 10G Ethernet
  • SRX5K-FPC-IOC: modular IOC with slots for two port modules
  • SRX5K-IOC4-10G: fixed-configuration IOC with 40 SFP+ ports that support up to 10G Ethernet
  • SRX5K-IOC4-MRAT: fixed-configuration IOC with eight QSFP+ ports that support up to 40G Ethernet and four QSFP28 ports that support up to 100G Ethernet (max. throughput is 480 Gbps)
  • SRX-IOC-16GE-SFP: fixed-configuration IOC with 16 SFP ports that support up to 1G Ethernet
  • SRX-IOC-16GE-TX: fixed-configuration IOC with 16 RJ45 ports that support up to 1G Ethernet
  • SRX-IOC-4XGE-XFP: fixed-configuration IOC with four XFP ports that support up to 10G Ethernet
