"Confirm with your array vendor that the disk array is not flushing its cache
after flush write cache request issued by Oracle Solaris ZFS"
The above text is taken from the document which you have referred. If this is the one you are concerned about, then below is the answer.
The Operating System may issue request to flush the cache, this flushing will be done at host/server level, the memory buffers will be flushed, so that the IOs there in that buffer are transferred to the disk array.
Disk array flushing is controled by the storage system itself. The storage array decides by its own according to the configuration made, when to flush the write cache of storage memory.
According to, this could you tell to me if there are specials considerations or configurations to get more efficienet data cache transfert from Os memory to disk array ? It there a best practise using ZFS on CX4 arrays about using only one cache level. ( at Os level or array level ). What do you recommend with ZFS ?
