When delivering a distributed storage project, Huawei engineers focused on introducing OceanStorPacific’s parallel file system service to customers. Which of the following descriptions of this service is wrong?
A . Use fixed-length, large-grained primes to ensure large I/O sequential read and write performance
B . Large I/O can be forwarded to the home node for direct processing, eliminating the distributed lock overhead, thereby significantly reducing the read and write latency of large I/O
C . Small I/Os are aggregated through the cache before being put into disk, which not only achieves ideal latency but also improves the utilization rate of small files.
D . In terms of I/O flow, large I/O is transferred to the disk in a direct manner to improve bandwidth capacity
