100G card support for SSG 200
In this article we will consider an example of a real load on a 64-core processor for SSG 200 in BRAS/NAT/DPI mode.

SSG 200 is designed to carry 100Gbps Full duplex traffic, i.e. up to 100Gbps of incoming and 100Gbps of outgoing traffic in Inline mode.

3-shema-angl-v3

In Inline mode, 2 100G ports are oriented toward subscribers (in) and the other two ports are oriented toward the Internet (out).

vStack-R-ASR201-S08RE2 Server Specification

  • AMD EPYC 7713 (64 cores)
  • 2U Heatsink
  • 8 x 32GB DDR4 RDIMM 3200MHz
  • LSI 9361-8i (1GB)
  • 2 x 960GB SATA SSD (front slots, PM893)
  • 2 x Dual ports 100Gb Eth QSFP28 PCIe 4.0 (Mellanox MCX516A-CDAT)
  • 1 x 1TB NVMe SSD (990 PRO)
  • 2 x 1Gb RJ45 (built-in)
  • Dedicated 1Gb RJ45 management interface
  • 2 x PSU AC 1300W
  • Rack Mount Kit
  • Standard “8x5xNext Business Day+5” warranty, 3 years

100G cards with mlx5 driver (Mellanox ConnectX-4, ConnectX-5, ConnectX-6) must be used. The motherboard and network card must support PCIe 4.0.
