using hypertransport technology in multi-processor servers enables scalability through the use of a cache coherency protocol which allows many multi-core processors to share a common memory space.
cache coherency is difficult to maintain during data movement among shards and developers need to be wise to update the shard map simultaneously as data movement occurs.
当数据在多个分片之间移动时将很难维护好缓存一致性,在有数据移动时,开发者需要同步更新分片映射才行。
if there is contention between san clients,nas-style cache coherency is invoked.
如果san客户机之间有连接,就激活了nas风格的高速缓存相干性。
intuitively this problem is very similar to the cache coherency problem.
直觉上,这个问题有些类似于缓存一致性。
in this paper, we analyzed the traditional cache coherency scheme, and described a cache scheme based on peer mobile client, which applied the new concept on the time stamp scheme based on windows.
