Notes:
[1] - cold pool needs 3 additional nodes or mixing of NVMe/SSD and HDD disks in nodes;
Networking
2x Data L3 switch
• 24x 25GbE/40GbE (should be aligned with Compute and Storage nodes network interfaces)
• Support VRF (more than 100)
• Support VLAN
• Support BGPv4
• Support HSRP / VRRP
These switches are connected to:
• Server equipment
• Management switches
• Internet uplink
• Customer connection uplinks
• all equipment is connected by two Direct Attach Cable 25GbE links aggregated over LACP
2x Management Switch
• 48x 1GbE; 4x 10GbE/25GbE/40GbE uplink
• uplink connected to DataSwitch and Datacenter management infrastructure
• all server management ports are connected (connections are distributed across switches)
• all ports of the LOM server are connected via LACP
Internet
• public autonomous system
• public IP /24 subnet (256 ip addresses)
• main ISP link with bandwidth 500Mbit
• reserve ISP link with bandwidth 100Mbit
