Your customer is planning to migrate a SQL Server environment hosted on a Symmetrix to a
CLARiiON. They have enabled “SafeWrite” for DB volumes on the Symmetrix, which protects any
pending writes that are being overwritten by new writes to the same area in global memory. The
customer wants to know why this configuration setting is not available on the CLARiiON.
How would you respond to this query?

A.
SafeWrite is not required since the CLARiiON writes are initially accepted in a buffer area, then
copied to global memory

B.
SafeWrite is not required since the CLARiiON writes are initially accepted in the global memory,
then copied to a buffer area

C.
CLARiiON architecture does not support SafeWrite since it writes directly to RAID-protected
disks

D.
SafeWrite is enabled on SQL Server for CLARiiON implementations
