Emerging Ethernet standards and their impact on storage

Over the past decade, Fibre Channel (FC) technology has been the norm when it comes to data centers. With storage applications such as data backup, replication and disaster recovery, it was used to connect storage to servers. FC backbone uses highest speed of 64 Gigabits per second (32G), which explicitly requires leased lines consisting of FC switches and bridges to be connected to Storage, and implicitly adding more cost to the infrastructure. Using latest technology of 100G RDMA (Remote Direct Memory Access), it is possible to achieve transfer speeds of 100 Gbps (Gigabits per second) with lower latency on the existing Ethernet switches and routers over long distances up to 300kms.  Will focus on how 100G Ethernet could replace the FC back-bone for storage connectivity with High Availability (HA) and Disaster Recovery (DR).Basically explains the front  (client-facing data ports ) and backend support (Storage and HA interconnect)  on 100G infra with Storage platforms .

 

This talk will mainly focus on NVMEoF  connectivity with RoCE v2 to achieve high speed storage access with low latency  and provide HA and Disaster Recovery seamlessly
