Hi all,

how many DS60 shelves can I connect to a Data Domain 6800?

From the product overview I learned that the maximum capacity of a DD6800 with extended capacity is 288 TB.

The "Hardware Overview and Installation Guide" states that a DD6800 can have up to 28 ES30 shelves (4*7, page 52). But there is no information about the amount of DS60 shelves. Just a drawing of a DD6800 with five DS60 shelves (page 60).

If I'm correct, a fully loaded DS60 shelve has the capacity of 192 TB when using the 4 TB HDDs. That means I can only connect one shelve to the DD? Two shelves would exceed the maximum capacity.

I have a customer who wants to buy a DD6800 and he needs 190 TB on the base configuration. Than he wants to expand the DD every year for the next four years by an additional 180 TB. But in my eyes the DD6800 can not fulfil this requirement.

Any help or suggestions are appreciated, thanks!

Cheers
