Can not view Symmetrix DMX-3 Best Practices Technical Note pdf

The URL you are reference appears to be out-of-date. It looks like there has been a minor revision. The current URL is:

http://powerlink.emc.com:80/km/live1/en_US/Offering_Technical/Technical_Documentation/300-004-800_a02_elccnt_0.pdf

(Note the change from "a01" to "a02". I'm in contact with the publishing team to see if they can search for occurrences of this link and update it, or if you happen to recall where you found that link that would be great.

Regards,
Dale
