This paper addresses the major challenges that large organizations face in protecting their valuable data. Some of these challenges include recovery objectives, data explosion, cost and the nature of data. The paper explores multiple methods of data protection at different storage levels. RAID disk arrays, snapshot technology, storage mirroring, and backup and archive strategies all are methods...

Suitable composable data center networks (DCNs) are essential to support the disaggregation of compute components in highly efficient next generation centers (DCs). However, designing such DCNs can be challenging. A DCN that adopts a full mesh backplane between disaggregated within rack and employs dedicated interfaces on each point-to-point link is wasteful expensive. In this paper, we propose...

Optimization of data center performance for reduction in power and cooling costs is crucial to the growth of IT services both in enterprise and consumer sector. Significant work has been conducted in the past to understand the thermodynamic variables and parameters that influence the environmental conditions of the rooms vis-a-vis the computer room air conditioning (CRAC) units, racks and serve...

Cooling buildings with large airflow rates of outside air when temperatures are favorable is an established energy-saving measure. In data centers, this strategy is not widely used, owing to concerns that it would cause increased indoor levels of particles of outdoor origin, which could damage electronic equipment. However, environmental conditions typical of data centers and the associated pot...

U.S. data center energy consumption is expected to double every 5 years, as shown in Fig. 1, at a huge cost both financially and to the environment. Microsoft itself launched two new mega-data centers last year, in Dublin and in Chicago. Sadly, much of the power consumed by these data centers is wasted. As documented in a recent Google study, [2], servers are only busy 20-30% of the time on ave...

Data centers today form the backbone of cloud operations. A well provisioned data center network is important to ensure that servers do not face bandwidth bottlenecks to utilization; to isolate services from each other; and to gain more freedom in workload placement, rather than having to tailor placement of workloads to where bandwidth is available [16]. As a result, a significant body of work...
