Sorry, that's old news. I did some research -- it looks like the
licensing model changed starting with WAAS software release 4.1. You
_do_ actually need to purchase an Enterprise license for the Central
Manager WAE.

You might do something like this:

7 x Enterprise licenses (1 x for the Central Manager WAE AND 6 x for
the Accelerator WAEs) OR

1 x Enterprise licenses (for the Central Manager WAE) AND 6 x
Transport licenses (for the Accelerator WAEs) OR

(1+n) x Enterprises licenses (for the Central Manager WAE AND n x for
the Accelerator WAEs) AND 7-(1+n) Transport licenses (for the
Accelerator WAEs), depending on your needs.

The point is, you might not need Enterprise functionality at all
locations, and it could be a waste of money, particularly at the DR
site where there might not be much 'user' traffic. Enterprise
functionality gives you nothing at the DR site, if (for example) all
the traffic is SAN-to-SAN replication. Pay particular attention there,
because I've seen SAN replication protocols (e.g. Hitachi TrueCopy)
that aren't even TCP-based. This may have implications for WCCP
intercept/redirect.

The key point you seem to be missing is that you need a dedicated WAE
for the Central Manager role. You need at least _seven_ WAEs to
support 6 locations. It's usually always ( WAEs required = n [sites] +
1 ), but sometimes you might have multiple WAEs at a single site, for
redundancy. In our WAAS deployment, we have dual WAEs at every site
and a standby Central Manager, too. We have (( WAEs required = ( 2 x n
[sites] ) + 2 ))

If you decided you needed the functionality provided with the
Enterprise license, your bill of materials might look like this:

 1 x WAE-XXX (Central Manager -- pick the hardware based on your fault
tolerance requirements)
 2 x WAE-674-K9 (DC and DR)
 4 x NME-WAE-502 (Branch sites)
 2 x WAAS-ENT-APL (for the 674s)
 4 x WAAS-ENT-NM (for the NMs)

Yes, you need an extra WAE.

But as stated above, it seems that beginning with WAAS software 4.1,
the Central Manager WAE requires an Enterprise license, and the old
'Central Manager' license (cheaper than Enterprise!) is defunct.

The information online is not clear because sometimes it doesn't state
whether it's based on the licensing model for WAAS 4.0 or 4.1. To be
sure, contact your local Cisco SE, or your reseller; that's what
they're there for.
