High performance computing (HPC) applications are becoming more data-intensive and produce increasingly large I/O demands on storage systems. New storage devices such as SSD which has nearly no seek latency and high throughput have been widely used together with HDD to serve as a hybrid storage system. To solve the I/O bottleneck problem, existing hybrid storage solutions such as Burst Buffer have...
Virtualization can provide significant benefits in data centers, such as dynamic resource configuration, live virtual machine migration. Services are deployed in virtual machines (VMs) and resource utilization can be greatly improved. In this paper, we present VScheduler, a system that dynamically adjusts processor resource configuration of virtual machines, including the amount of virtual resource...
In multi-VM (virtual machine) environment, the virtual machine network management plays an important role. Traditional multi-VM management systems are accustomed to using the DHCP mechanism. However, with the development of virtual network technology, DHCP is not suitable for constructing the stable and transparent virtual network environment. In this paper, we propose a method of multi-VM automatic...
