For our network we use 3 hardware vendors:
Arista - for routers and core switches
Arista & Huawei - for edge switches
Ruckus - for management switches
Our network consists of 4 layers:
- Routers
- Core switching
- Edge switching (10 and 1Gb)
- Management switching
Routers
For routing we use Arista 7280 series routers, minimally equipped with 32GB RAM. The routers are redundantly configured using the VRRP protocol and route traffic based on BGP information.
Core
Our core switching consists of Arista 7060 series switches. Each switch provides 32x 100Gb/s fiber ports. With at least 4 ports we interconnect the different datacenters, providing at least 400Gb/s capacity.
Edge
The first edge switches are Arista 7050 series switches, offering 48x 10Gb/s fiber ports. Ideal for high-capacity servers. These are connected to the core with 40Gb/s or 100Gb/s uplinks.
The second edge switches are Huawei 5720 series switches. These provide 4x 10Gb/s uplinks to two different core or edge switches and deliver 1Gb/s UTP connectivity to servers.
Management
The management network is a separate network between all servers and IPMI. By separating it from the main network, we can also use it as a backup network, ensuring we always have access to all devices. Since this network does not require a high management overhead, we use the Ruckus ICX series.
