Which recommendation is most likely to improve performance for the home directory clients?
An EMC VNX supports several iSCSI Windows hosts, as well as a home directory structure for
fifty CIFS clients. The iSCSI hosts run an application with an I/O pattern that is 80% writes with a
2 MB I/O size. The customer reports overall write performance is less than expected. Your
examination of the VNX reveals frequent forced flushing. Which recommendation is most likely to
improve performance for the home directory clients?
