What elements remain unresolved to make FCoE truly world-class? What should the vendors be prioritizing?
I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.
The battle lines are drawn between 8 Gb Fibre Channel and 1 Gb or 10 Gb iSCSI and NFS. This is the baseline for my Interop debate. I am not arguing about the future of SAN, or even iSCSI versus NFS. Rather, I am arguing that most businesses would be best served by implementing an iSCSI SAN rather than purchasing Fibre Channel today.
iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.
Storage protocols continue to mimic direct attached storage, with the concepts of block and file at its core. No amount of virtualization, and no new protocol, will fix this – we need a storage revolution.
