 各位老师,同学,大家好:

应实验室邀请,Florida International University (FIU)的赵明博士将访问实验室,并做学术交流,欢迎各位老师和同学参加。
 
时间:5月9日(星期四)上午10:00
地点:光电实验室A302
报告题目:QoS-driven Management of Cloud Storage
报告人:赵明,Florida International University (FIU) 
报告摘要:
As the adoption of cloud computing rapidly grows, there is an increasingly urgent need for cloud systems to deliver performance guarantees, so that users are comfortable to run their critical applications on shared infrastructure, and providers are able to offer more economical performance-based Service Level Agreements (SLA). However, it is still challenging for existing resource management solutions to meet such requirements: first, cloud workloads often exhibit highly dynamic and complex behaviors which make it difficult to accurately estimate their resource demands; second, these workloads typically require multiple types of local and distributed computing and storage resources which are difficult to manage in a holistic manner. 
This talk will present several recent efforts on cloud storage management to address the above challenges and provide quality-of-service (QoS) guarantees to cloud applications. First, it will introduce a new integrated host-side IO scheduler for flash-based solid-state devices (SSDs) which coordinates and optimizes the scheduling of system and maintenance IOs in a holistic manner. Second, this talk will present dm-cache, an SSD-based storage cache deployed in production cloud systems and the findings from a trace-driven analysis of the cacheability of cloud workloads. Finally, the talk will also introduce the highlights of the complementary work on the storage management of emerging big-data systems.
