25G TOR Switch for cloud computing data center
As the demand for high bandwidth is soaring, 10GbE has met its bottleneck in switch-to-server connections. And 25G Ethernet is the new standard offering significant density, cost and power benefits for server to switch links. This makes 25G switch very popular in recent years.
25G Ethernet has broad market potential in the server interconnect applications. This part will explain the advantages of using 25G Ethernet switch for switch-to-server connections.
Faster Speed
Data center is expanding at an unprecedented pace now, driving the need for higher bandwidth between the servers and switches. This means 10GbE is no longer fast enough for switch-to-server connection. Therefore, several big data center and cloud computing providers (Google, Microsoft, Broadcom, Arista, Mellanox, etc.) have formed the 25 Gigabit Ethernet Consortium. In addition, IEEE also formed a 25G Ethernet study group.
Cost-Effective for Moving to 100G
Although the Ethernet speed upgrade path of data center is defined as 10G→40G→100G, the latest upgrade path for server connections will be 10G→25G→100G. This is because upgrading from 10GbE to 25GbE offers both CapEx and OpEx savings for backward compatibility. Further more, 25GbE provides a simpler path to future Ethernet speeds of 50 Gbps, 100 Gbps and beyond.
