SBS 2011 - How many servers can I have in the domain ?

Hi

I am about to replace an SBS 2003 server (see question ID27789091) and will probably purchase SBS 2011, with the Premium add-on.

Now I know that the Premium add-on gives a second Windows 2008 R2 standard license. However the question is, can I have MORE than two servers within an SBS 2011 domain (I know that the SBS 2011 box needs to be the AD controller) ?

At present I envisage one box for the general SBS stuff (AD, DNS, DHCP, WSUS etc) plus Exchange and a second for Sharepoint and SQL server.

However, it might make sense to have a third box for general file-and-print duties (and maybe double-up as a Lync server) and possibly even a fourth for CCTV footage.

Assuming that I buy Windows 2008 server licenses for the third and fourth servers, can SBS 2011 cope with my proposed setup (and do the user CALs cover multiple servers) ?

Finally, I know that the modern trend is towards virtualisation, but for resilliance reasons, my MD does not want all of our (IT) eggs in "one basket".

As always, any feedback or guidance gratefully received.

Kind regards

Yes the user CALS cover the other servers as long as the servers have server licences.

Hi Duckx/ArneLovius

xDuckx - I knew that SBS was limited to 75 CALs and assumed that there would be a similar restriction in SBS for the number of servers in the domain. From what you are saying, that positively isn't the case ?

ArneLovius - Thanks for that. Can I loosely interpret an SBS CAL as a 'domain' license, then ?

Kind regards

there is no limitation on the number of servers; in the same way if you have user CALS there is no limitation on the number of desktops, if you have device CALS there is a limit on the number of desktops...

The SBS CAL covers all of the services on SBS, if you add another file server, access to it would be covered once you had purchased the Windows server licence. If you added an application that required SQL server, then on top of the Windows Server licence, you would also need either a SQL server licence and CALS for all users that used the application, or a "per processor" SQL server licence. If you added a terminal server, then again on top of the Windows Server licence, you would require remote desktop CALS
Hi tsaico

Many thanks for your input and for the link. I agree that the PDF suggests that additional CALs are not needed for other Windows 2008 servers in the domain.

ArneLovius - I am sort of with you in terms of additional (non-SBS) services, although the SQL server comment would surely be covered by purchase of the Premium add-on ?

A couple of further 'real world' questions :-

1) If I purchase the SBS Premium add-on, for 25 SQL server users, do I need to buy BOTH a 20 user SBS CAL pack AND a 20 user Premium CAL pack, or only the Premium CAL pack ?

2) What would your view be if one of the extra file-and-print servers was running Server 2012 - would the SBS CAL still cover it as it is part of the SBS domain ?

Thanks once again.

Kind regards
