2017 IEEE Systems Journal  
The experimental result shows that our work can effectively improve the disk I/O performance of VMs. Meanwhile, it brings moderate overhead for VM live migration.  ...  In such a way, a VM disk I/O request may be proceeded locally in NAS client, instead of walking the external networking path repetitively between NAS server and client.  ...  VM Live Migration Compared with the original NAS architecture, Triple-L complicates the procedure of VM live migration [23] in that local sub-files in Log-Split and Local-Swap are both required to transferred  ...

Weida Zhang, King Tin Lam, Cho Li Wang
2014 2014 IEEE 7th International Conference on Cloud Computing  
Various strategies have been proposed for fast VM live migration over a local-area network (LAN). The most common solution uses memory pre-copying and assumes storage is shared on the LAN.  ...  This paper proposes a three-phase, fractional, hybrid pre-copy and post-copy solution for both memory and storage to achieve highly adaptive and responsive WAN-wide migration.  ...  In general, the accuracy of We also evaluate the prediction of storage access based on an I/O-intensive program-SysBench [16] .  ...
