This week’s podcast looks at storage networking and in particular the choice of using Ethernet vs Fibre Channel as the network protocol. Traditionally, enterprise storage platforms have been Fibre Channel connected, with only a small amount of iSCSI usage. However, the world isn’t just block storage and in fact, as guest Marty Lans (General Manager, Storage Connectivity Engineering & Global Interoperability Business Unit at HPE) tells us, 80% of storage is Ethernet connected. This is because of the growth in unstructured data stored on NAS and object stores.
Ethernet storage now includes lossless Ethernet (DCB) and has done for some time. Ethernet is faster than Fibre Channel in raw throughput, yet Fibre Channel continues to see modest growth, according to Lans. The next wave of storage networking is coming along with the introduction of NVMe. This will bring FC-NVMe and NVMe-oF protocols, both improving performance for shared storage. So is it the end for Fibre Channel, should the default be to move to Ethernet? The answer isn’t that clear cut, as Marty explains.
