Re: EMC striping question

Hi Hans,

Absolutely not true, and has not been true for a long time. Writes to an EMC never go directly to disk anyway, and when they do go to disk is purely determined by the microcode algorithms, and will often have nothing to do with stripe layout at all.

Thanks,
Matt
