NTT is considering Data-Centric Infrastructure (DCI) using IOWN technologies. DCI processes data efficiently by combining geographically dispersed resources. To achieve this, we’re verifying Composable Disaggregated Infrastructure (CDI) – a flexible hardware solution – and considering a multi-vendor approach. CDI consists of servers, PCIe expansion boxes, and switches, enabling software-controlled allocation of accelerators for optimal performance. Utilizing multi-vendor CDI requires an interface like OFA Sunfish to reduce operational costs. Our verification has revealed challenges in the physical operation of CDI and implementing a multi-vendor configuration. These include increased cabling costs, racking limitations, and inconsistencies in product functionalities and procedures requiring careful configuration management. This session will share these challenges and proposed solutions.
