Single-choice SmartDedupe& SmartCompression technology in Huawei Oceanstor all-flash storage When writing data, calculate the similar fingerprint (SFP) and weak hash fingerprint (FP) at the same time, if the fingerprint already exists in the local fingerprint table, Then perform online deduplication; if it is new data, perform compression and save similar fingerprints, and then perform background deduplication.
Based on the characteristics of big data, Huawei distributed storage can adopt a single-select Scale-out architecture and use general-purpose server hardware to provide large data. According to the storage platform.
The peak write bandwidth of an application is 10MB/s, the average write bandwidth is 200KB/s, and the average write IO size is 4KB (private The information overhead is about 11%, and the bandwidth utilization rate is 70%). Use FC networking and set to synchronous remote replication mode (consider private If there is information overhead), which is the correct requirement for network bandwidth?
