The Model of Meta-data Cache on Client Node in Blue Whale Distributed File System
Huang Hu · 2005
In Blue Whale distributed file system, the meta-data server handles all the meta-data through remote proce- dure calls, and all the data flows directly between clients and storage nodes. Because of communication delay, the meta- data exchanging between clients and servers has great impact on the whole system performance especially when the load is heavy. We propose a model to maximize the meta-data cache on client node that dramatically reduces the RPC messa- ges when itreads and writes data. This model greatly improves the reading and writing performance of Blue Whale dis- tributed file system. s
