Description

The Arista 7170 is a 1RU fixed-configuration programmable data centre switch built for high-density 100GbE leaf or spine switching in cloud and large-scale data centre networks. Its programmable architecture lets operators reconfigure packet parsing, lookups, traffic scheduling, packet modification and monitoring, and every QSFP port supports flexible 10G to 100G breakout.

This SKU is the High Capacity variant with front-to-rear airflow and two AC power supplies. It provides 32 QSFP100 ports (40/100GbE) plus 2 SFP+ ports, with 6.4 Tbps throughput, up to 2.4 Bpps forwarding and latency from 800 ns. It carries a 20 MB packet buffer and 16 GB of system memory. Port density scales to 128 x 25GbE or 130 x 10GbE using breakout. Dual 747W AC hot-swap supplies run 1+1 redundant, with four hot-swap fans in an N+1 arrangement. Typical draw is 221 W and maximum draw is 490 W.

The switch runs Arista EOS (minimum release 4.21.0F) and sits in EOS Feature License Group 2. The QSFP ports accept 40G and 100G optics and DAC/AOC cables, while the SFP+ ports take 10G and 1GbE modules.

FAQs

Q: Which optics and cables work in the QSFP and SFP+ ports?
A: The QSFP ports support 40G optics (SR4, XSR4, SRBD, UNIV, PLR4, LR4, ER4, CR4, AOC) and 100G optics (SR4, XSR4, SWDM4, SRBD, LR, LR4, XCWDM4, CWDM4, PSM4, ERL4, AOC, CR4), plus 25GBASE-CR via QSFP to SFP25 breakout. The SFP+ ports support 10G (CR, AOC, SR, SRL, LR, ER, ZR, DWDM) and 1GbE SX/LX/TX.

Q: Which EOS licences are available for this switch?
A: It runs Arista EOS and is in Feature License Group 2. Optional licences include LIC-FIX-2-E (Enhanced L3), LIC-FIX-2-V (Virtualization), LIC-FIX-2-V2 (EOS Extensions, Security and Partner Integration), LIC-FIX-2-Z (Monitoring and Automation) and LIC-FIX-2-FLX-L (FLX-Lite routing, EVPN, VXLAN, SR).

Q: What power supplies does it use?
A: It uses two hot-swap 747W AC supplies (100-240VAC, 50/60Hz, IEC C13) in a 1+1 redundant arrangement. Typical draw is 221 W and maximum draw is 490 W.

Q: What airflow does this SKU have and which fan modules fit?
A: This SKU is front-to-rear airflow with four hot-swap fans in an N+1 arrangement. The spare fan modules for 1RU 7170 systems are FAN-7000H-F and FAN-7000H-R.

Q: Can the 100G ports run at lower speeds?
A: Yes. Every QSFP port supports flexible 10G, 25G, 40G, 50G and 100G operation via breakout, with hitless speed changes. This allows up to 128 x 25GbE or 130 x 10GbE ports.
