FPR4145-ASA-K9 Description

The FPR4145-ASA-K9 is a Cisco Firepower 4100 Series ASA firewall appliance for data center and enterprise edge boundaries with large session counts. The 1RU appliance provides 80 Gbps of stateful inspection throughput (1500B UDP), 50 Gbps multiprotocol throughput, 40 million concurrent connections, 20,000 VPN peers, eight 1/10G SFP+ ports and two network module bays. ASA and Threat Defense are separate appliance models on the 4145 hardware.

Key Features

Multiprotocol Throughput And Session Scale

The 4145 sustains 50 Gbps of multiprotocol traffic with 40 million concurrent connections and 1.5 million new connections per second. The 4125 stops at 45 Gbps, 25 million and 1.1 million.

384 GB Memory

Memory is double the 192 GB on the 4115 and 4125, which is where the larger connection table is held.

Two 1100W AC Supplies Installed

The chassis ships with dual 1100W AC supplies in 1+1 redundancy. A 950W DC supply is the optional DC input.

Eight SFP+ Ports With Two Module Bays

The fixed SFP+ ports run 1G or 10G, and the bays add 100G, 40G, 10G or fail-to-wire modules. The maximum is 24 x 10G or 4 x 100G ports.

IPsec Capacity For Large Remote Workforces

IPsec throughput is 23 Gbps and the peer limit is 20,000, against 19 Gbps for the 4125 and 15 Gbps for the 4115.

Contexts And Clustering

Ten security contexts are included up to 250, and ASA active/active high availability uses multiple contexts. Clusters can reach 16 appliances.

Application Scenarios

Large Data Center Edge

A data center with heavy east-west and north-south flows can place the appliance at its edge, where 40 million concurrent connections and 1.5 million new connections per second set the session ceiling.

Enterprise VPN Hub

A multinational network that backhauls branch and remote-user tunnels to one site can terminate them on the appliance, which carries 23 Gbps of IPsec throughput and 20,000 VPN peers.

Multi-Tenant Firewall Contexts

A hosting provider can give each customer a separate security context, starting with 10 included and extending to 250 on the same chassis.

Dual 1100W AC

FPR4145-ASA-K9 and FPR4125-ASA-K9 are both 1RU ASA appliances with 800 GB of storage and dual 1100W AC supplies, and FPR4145-ASA-K9 has 384 GB of memory against 192 GB, 50 Gbps of ASA multiprotocol throughput against 45 Gbps, 40 million concurrent connections against 25 million, and 23 Gbps of IPsec VPN against 19 Gbps. Sites whose ASA sizing stays within 45 Gbps, 25 million connections and 19 Gbps of IPsec VPN can order FPR4125-ASA-K9 instead. FPR4145-NGFW-K9 has identical hardware and the same figures in the table, so the choice between it and FPR4145-ASA-K9 is only the software the deployment runs, ASA or NGFW.

    Our annual vendor review consistently rates Layer23 among the best. Took a little longer to clear customs than expected, otherwise excellent.

Questions & Answers

  • Does FPR4145-ASA-K9 support RAID on its two SSD slots?

    No, FPR4145-ASA-K9 does not support RAID. SSD slot 1 holds the primary SSD, which must always be installed and carries the logical device application instance (ASA), and slot 2 is only for the optional MSP. The 800 GB spare is FPR4K-SSD800=, and an empty slot takes the FPR4K-SSD-BBLKD= filler, per the Firepower 4100 hardware installation guide.
  • What software does the FPR4K-NM-2X100G module need in FPR4145-ASA-K9?

    FPR4K-NM-2X100G needs FXOS 2.13 or later and ASA 9.18.1 or later on FPR4145-ASA-K9, per the Cisco FXOS compatibility tables. The 4-port 100G module and the double-wide FPR9K-DNM-2X100G are not supported on the Firepower 4100 chassis.
  • Which FXOS release do the hardware bypass modules need in FPR4145-ASA-K9?

    FPR4K-NM-6X1SX-F, FPR4K-NM-6X10SR-F, FPR4K-NM-6X10LR-F and FPR4K-NM-2X40G-F need FXOS 2.0.1 or later in FPR4145-ASA-K9. FPR4K-NM-8X1G-F needs FXOS 2.1.1 or later, and the FXOS CLI may display it as the base PID FPR-NM-8X1G-F without the 4K prefix.
  • What fills an empty network module bay in FPR4145-ASA-K9?

    An empty bay in FPR4145-ASA-K9 takes the FPR4K-NM-BLANK= blank cover, per the Firepower 4100 hardware installation guide. Every network module also has a spare version ordered with the equals sign, for example FPR4K-NM-4X40G=.
  • Is there a bundle PID that includes FPR4145-ASA-K9?

    Cisco lists FPR4145-BUN as the Master Bundle PID for the 4145 chassis and advises ordering it unless there is a specific reason, because the bundle brings all required components. The single-chassis PID FPR4145-ASA-K9 is described as Appliance, 1RU, 2 x Network Module Bays.
  • What current does each AC supply in FPR4145-ASA-K9 draw?

    Each 1100W AC supply is rated 13 A on 100 to 240 V input, with efficiency above 92 percent at 50 percent load, per the Cisco Secure Firewall 4100 datasheet. The optional 950W DC supply is rated 27 A.
  • How many TLS proxy sessions can FPR4145-ASA-K9 handle?

    FPR4145-ASA-K9 supports 15,000 total TLS proxy sessions, per the ASA 9.22 license limits table. That ceiling is the same on every 4100 model and is separate from the 40 million concurrent connection figure for plain stateful inspection.
