Sure, the cache is nice. EMC are the gods of cache....Eventually, the writes have to be made permanent. What happens when the cache is full? Right, EMC blocks io until most of the io has gone to disk. This leaves the poor user waiting, and waiting, and grow a beard.
Symmetrix is limited to a 64G cache anyway.I think we should move to OS striping.
Thanks.

Why worry about how it gets written. The cache will make any implementation sing like a bird. And if you think
you are having problems just add more cache and that will take care of it.

Hi All,
Today I saw an archived thread on orafaq about striped volumes in an EMC Symmetrix. Gaja mentioned that writing to a striped volume is performed in a sequential fashion i.e. spindle B will not start writing block 2 before spindle A has completed writing block 1.
Is this still true for a Symmetrix with 5568 firmware? Perhaps it's a better idea to let the OS handle the striping?
Regards, Hans de Git
