Characterizing and optimizing TPC-C workloads on large-scale systems using SSD arrays
2016
Science China Information Sciences
Preserved Fulltext
First, we propose an approach based on SmallFile table space to organize the test data in a round-robin method on all of the disk array partitions; this can make full use of the underlying disk arrays. ...
Transaction processing performance council benchmark C (TPC-C) is the de facto standard for evaluating the performance of high-end computers running on-line transaction processing applications. ...
In the second storage environment, we used our proposed SmallFile table space method to manage the underlying disk arrays. Each disk array was partitioned into a number of 8 GB blocks. ...

We also outline necessary extensions for transaction management (concurrency/coherency control, logging/recovery) to support intratransaction parallelism in the Shared Disk environment. 41-1 41·2 Parallel ...
In panicular, the shared memory can become a performance bottleneck thereby limiting the scalability of the architecture. ...
Hence, SD is better positioned than SN or SE to utilize disk arrays for parallel query processing. Of course, SD can also use conventional disk farms instead of disk arrays. ...

Because these kinds of cloud systems require high performance and reliable storage, the use of flash-based Redundant Array of Independent Disks (RAID) will increase. ...
Unlike the traditional data deduplication method, it only removes parity data, which will be stored in the parity disks of the all flash array. ...
But the proposed parity deduplication method shows 95% and 96% of the write performance in the same environment. ...
