Investigating the Challenges Facing Composable/ Disaggregated Infrastructure Implementation: A Literature Review

There has been an exponential growth of IT technologies in the past few decades. Many technologies target the improvement of IT infrastructure as it plays a primary concern of any IT management. Composable / Disaggregated Infrastructure (CDI) is one of the newest technologies introducing a new concept to manage the IT infrastructure. However, many challenges arise at the beginning stages of any technology life cycle. Hence, this study aims to investigate the challenges involved in migrating or implementing CDI for an oil and gas organization in Oman. To achieve this aim, the research employs a systematic literature review for the studies conducted by academics and industrial institutions. To link the results with an existing organization, an interview was conducted with an IT governance expert from a leading oil and gas organization in Oman. This study provides a holistic view of the highlighted challenges faced with CDI technology. The results highlighted five main challenges, which are controlling end-to-end latency, supporting higher bandwidth and bandwidth density, scaling of the network, orchestration of resources, and power consumption. Key challenges such as end-to-end latency, supporting higher bandwidth, and density can be addressed by using Silicon Photonic (SiP) transceivers. For the oil and gas sector, if the large-sized organizations decide to proceed with CDI migration or implementation, the organizations are prone to face two main challenges: scaling the network and orchestrating resources, thus these challenges still need to be addressed.
