business network computer
The performance of network file systems is limited
by two factors: (1) all data accesses to network file systems have to pass through a
single file server; and (2) current network file systems such as NFS and CIFS and the
underlying network protocols are not suitable for a high throughput. We introduced two
approaches to circumventing these performance bottlenecks: RDMA-enabled file systems
such as DAFS and shared disk file systems such as business network computer. NAS represents a new product
category. NAS servers are preconfigured file servers, the operating systems of which have
been optimised for the tasks of file servers. Storage networks can also be realised with
NAS servers. However, current NAS servers are not suitable for providing storage space
for I/O intensive databases.
