Our company is mid-size, and we are considering the purchase of both Exchange server and SQL server.
Buying all the software products and CAL's seperately seems kind of expensive, so I'm wondering if anyone have hands-on experience with Windows Essential Business.
I'm also interested to find out if it have any limitations (other than the obvious 300 user CAL limit), like SBS's limitation on multiple domain controllers etc.
A quick note about our enviroment if it plays a role in this; we have a datacenter wich could hold atleast ten times the amount of employees we have. The reason for this is that we produce newspapers, radio and TV. We have redunant servers, fibre channel network, SAN etc. Just about everything is virtualized with VMware Infrastructure.
As you've already pointed out, the 300 user limit will be your major limitation, and if your not going to get to this, then Essential Business server is probably the most cost effective way to get the services you want.
The multiple domain controller issue has always been a common myth with SBS, you CAN have additional domain controllers with SBS, there recommended to provide fault tolerance. You cannot have another SBS server on the same network and I thing this is where the confusion came.
There are a few other limitations that you should be aware of, but are probably of limited concern:
Microsoft SBS and now Essentials server products are an excellent way for SME's to get Enterprise level products for an excellent price and I would recommend them for anyone who can fit under the user limit.
