Instead, a media server module can be installed together with a management server module on the same physical server.
Question 323
The peak write bandwidth of an application is 10 MB's, the average write bandwidth is 200 KB's, and the average write IO size is 4 KB. The overhead of private information is about 11%, and the bandwidth utilization rate is 70%. The network employs FC, and the synchronous remote replication mode (considering the overhead of private information) is enabled.
Then, which is the required network bandwidth?
Question 324
File-level deduplication is also known as single instance storage (SIS). Based on indexes, file-level deduplication checks and compares the attributes of a file that needs to be stored with those of files that have been stored. If the file has not been stored, file-level deduplication stores the file and updates indexes, Otherwise, file-level deduplication only stores the pointers that point to the existing file.
