CALs are version-specific to a point - i. If you are adding a second server which is WS, and you are keeping your WS server, you need to upgrade your CALs because you only purchased WS CALs which don't grant you the rights to connect to the newer server. If you were to install your second server as WS, you wouldn't need to purchase additional CALs, because as long as the version is the same, a single CAL grant you access to unlimited server of the same version. CALs can be tricky to correctly license.
FAQ 1. Office Office Exchange Server. Not an IT pro? Learn More. Don't forget you can use licensing groups to reduce the overall cost. If say you have users but they work shift patterns and you only have say users logged on at once through the day you can add all the users to a licencing group and as long as you never go over concurrrent users logged at once you are within your licensing terms.
I was confused by the licencing, so I phoned up Microsoft and the guy told me, if I set the licencing model to per user on my three new servers, if I buy 50 user cals, I can use them on all three servers, i.
I don't need per user cals for the 3 servers, just I'm surprised at how you describe this, because I've always been told that MS don't really recognise the concept of "concurrency" in their licencing.
You either have to work on the basis of the total number of devices or the total number of users although you can have chunks of each. The other things that surprises me is that there don't seem to be any licencing tools in Server - as far as I can tell it seems to be taken on trust.
I inherited a server and the only way I could find out how many CAL's it was licenced for was by trawling through invoices. Many staff worked off-site so we never had a full house of workers and have more users than cals. We get a licensing error whenever a user isn't added to the licensing group as we're just over now for number of staff vs cals. Using licensing groups in this manner was all in my MCSA training - I'll defo look into the server stuff now though if you think its not the same.
The concurrency is handled by "per server" licenses. Per user and per device don't care about concurrency. The "per server" license is a concurrency license. That is its sole purpose.
Pessable There is no enforcement of licensing in Server 08 they took it out because it didn't work well. It's kind of an honor system thing now. I always liked the old concept of "Per Seat" licensing. You could envision seats in an auditorium and every 8 hours different people sat in them. This would give you users with the seat model.
Also, this allows multiple server connections from these seats devices. You don't want to use per server licensing unless you only have one server or each server is dedicated to a set group of users. It was also stated that each server license came with 5 cals. Someone please correct me if I'm wrong, but these same OEM cals don't transfer to multi-server access as in a per user licensing model.
Most assuredly! If you don't believe me just visit www. They are just wealthy "philanthropists". I really like Michael Robertsons www. MS licensing confusing? This overview is for reference purposes only. Before purchasing, you should visit the "How to Buy" section for each product and consult your Microsoft representative or local reseller regarding your specific licensing needs. With the User CAL, you purchase a CAL for every user who accesses the server to use services such as file storage or printing, regardless of the number of devices they use for that access.
Purchasing a User CAL might make more sense if your company's employees need to have roaming access to the corporate network by using multiple devices, or from unknown devices, or if you simply have more devices than users in your organization.
Device CALs. With a Device CAL, you purchase a CAL for every device that accesses your server, regardless of the number of users who use that device to access the server. Device CALs may make more economic and administrative sense if your company has workers who share devices, for example, on different work shifts. External Connectors. If you want external users—such as business partners, external contractors, or customers—to be able to access your network, you have two licensing options:.
External Connector licensing. An EC license assigned to a server permits access by any number of external users, as long as that access is for the benefit of the licensee and not the external user. Each physical server that external users access requires only one EC license regardless of the number of software instances running. An "instance" is an installed copy of software. The right to run instances of the server software is licensed separately; the EC, like the CAL, simply permits access.
Under the Per Core model, when the server software is running in the physical OSE, you must license all physical cores on the server. To determine the number of core licenses you need, count the total number of physical cores for each processor on the server, and then multiply that number by the appropriate core factor. You do not need to purchase additional CALs. Software licensed by core. Specialty Server licensing. Specialty Servers are server-only licenses that generally do not require CALs.
Specialty Servers require a server license for each instance of the server software running on a server. You can run the instance in a physical or virtual operating system environment. By exception, some products provide more specific use rights.
Included with the ML are the rights to run the corresponding management server software, so you do not need to acquire separate licenses for the management server software. Software licensed by ML.
