All:

I have heard that the optimal size meta, for performance, is 8 TDEV's.  An EMC guy came in the other day, and said that for performance, my TDEV's should be 64GB max.  I can't live with 512GB metas.

Is the 64GB number real?  There are so many differing "best practices" out there, it's hard to know what's official.

Can anyone point me to a document, or clarify this at all?

Thanks,

Brandon
