Server options

If you prefer client and server licensing, you can acquire IBM® Lotus® Domino® server licenses determined by the total processor value units associated with your server machine(s) plus individual Client Access Licenses for each user. Two Lotus Domino server alternatives are available for licensing in this manner; both include messaging capability:

• IBM Lotus Domino Messaging Server combines full support for the latest Internet mail standards with Lotus Domino's industry-leading messaging, calendar and scheduling, discussion database and reference database capabilities - all in one manageable and reliable package. Lotus Domino Messaging Server also includes support for Lotus Domino partitioning (running more than one instance of Lotus Domino on the same machine using one copy of the Lotus Domino code).

• IBM Lotus Domino Enterprise Server provides all the functions of the IBM Lotus Domino Messaging Server, plus support for custom intranet and Internet applications. The applications may be developed in house using IBM Lotus Domino Designer or acquired from an Independent Software Vendor. Lotus Domino Enterprise Server includes support for Lotus Domino clustering, which allows data to be replicated in real time across a cluster of servers. This capability lets you balance server loads and take advantage of automatic failover when a server is unavailable.

Q. What is Lotus Domino software?
A. Lotus Domino software is server software that provides enterprise-grade collaboration capabilities across a wide range of uses and applications. Lotus Domino software can be deployed as core e-mail and enterprise scheduling infrastructure, as a custom application platform, or both.

Q. What is the difference between Lotus Domino software and IBM Lotus Notes software?
A. Lotus Domino software is server software that runs on a variety of operating systems, available through various licensing options and offerings. IBM Lotus Notes® is workstation (client) software that provides an individual user with an integrated collaborative environment. Lotus Notes is one of several client options for users to access the messaging and collaboration capabilities of the Lotus Domino server software.

Q. What are the Lotus Domino and Lotus Domino Express license types?
A. Three Lotus Domino Server license types are available to organizations of all sizes: IBM Lotus Domino Messaging Server (messaging only), IBM Lotus Domino Utility Server (applications only), and IBM Lotus Domino Enterprise Server (both messaging and applications).

Three IBM Lotus Domino Express offerings are available to companies with 1000 employees or fewer: IBM Lotus Domino Messaging Express (messaging only, licensed per user), IBM Lotus Domino Utility Server Express (applications only), and IBM Lotus Domino Collaboration Express (messaging and applications, licensed per user).

Q. What factors determine the number of Lotus Domino server licenses I need?
A. The required number of Lotus Domino server licenses is equal to the total number of processor value units associated with the physically available and active capacity of the machine(s) on which the software is installed. Virtualization Capacity licensing is an option for acquiring and deploying eligible Lotus Domino software. Virtualization Capacity licensing allows you to license software for use on less than the full processor core capacity of your machine - when the software program is used within one or more partitions using a supported partitioning technology.

For more details about virtualization Capacity licensing, see the IBM Passport Advantage Web site or consult your IBM sales representative or IBM Business Partner.

Q. I have Lotus Domino software installed on machines used only for emergency backup. Must I have licenses equivalent to the total processor value units for those machines as well?
A. If the Lotus Domino server software is installed on a machine for emergency backup purposes only and either (1) has not been started (cold backup) or (2) started but sitting idle (warm backup) and not doing work of any kind, there is no requirement to pay a license charge. Note that a scheduled hardware outage, such as preventive maintenance, installation of upgrades, or switching to a larger capacity machine during peak periods, is not considered a backup situation.

The following are examples of situations (not an exhaustive list) in which the software is considered to be "doing work" and would require Lotus Domino server licenses:

High availability configuration (for example, clustering or replication) even if the server is not being accessed by users Development, program maintenance or testing

Q: Which Lotus Domino server license type do I need for a Web site based on Lotus Domino technology?
A. Lotus Domino Enterprise Server and Lotus Domino Utility Server each support anonymous access to applications. If the application requires authentication, Lotus Domino Enterprise Server supports access by users who have Lotus Notes for Collaboration or Lotus Domino Web Access for Collaboration client access licenses (CALs). Authentication is involved whenever the application requires secure validation of a user's unique identity.

Lotus Domino Utility Server licenses support unrestricted access to non-mail applications by Web browser users, whether or not the application requires authentication. Access from a Lotus Notes client is allowed, but requires a Lotus Notes for Collaboration CAL acquired separately.

Q. I have deployed Lotus Domino Messaging Server software. How may I add entitlement for applications?
A. You may trade up your Lotus Domino Messaging Server licenses to Lotus Domino Enterprise Server, and trade up your messaging-only client licenses to collaboration client licenses. IBM offers in-family tradeup part numbers to make this easy and cost-effective. Tradeup pricing is generally lower than the difference between current prices of the existing and new licenses.

Alternatively or additionally, you may consider adding Lotus Domino Utility Server licenses if you want to extend the reach of authenticated access to non-mail applications to Web browser users (inside the company, external or both) - without the need for additional client access licenses. If your existing users want to be able to access applications using their Lotus Notes client software instead of a Web browser, they would need to upgrade their CALs to Lotus Notes for Collaboration.

Q. If I choose to add Lotus Domino Utility Server licenses, would I need to install another copy of Lotus Domino code on another machine?
A. You are allowed to deploy multiple server types on the same hardware, provided that your existing machine has adequate capacity to support the desired number of users in the new environment that adds non-mail applications. You can acquire more than one license type for the same hardware and the same copy of the code. The functions you are allowed to use and the entitlements that you have are determined by the type of license or combination of licenses that you acquire.

Q. I have deployed Lotus Domino Messaging Server software. How may I add entitlement to use clustering capability?
A. You may trade up your Lotus Domino Messaging Server licenses to Lotus Domino Enterprise Server. Please note that this is the only tradeup option available for Lotus Domino server licenses.

Q: Which Lotus Domino server license do I need for a passthru server, administration hub or gateway? The machine is not running either mail or collaborative applications.
A. For instances in which the machine is really just performing an administration function, Lotus Domino Messaging Server licenses are sufficient. But if you need clustering support, you will need Lotus Domino Enterprise Server. In either case, you will need licenses equivalent to the number of processor value units associated with the machine.

Q: May I use more than one Lotus Domino license type for the same hardware?
A. Yes, separate licenses can apply to the same hardware. For example, suppose you have users within your organization who need mail, but you want to provide Web self-service capabilities to your customers using a Lotus Domino-based application. You can acquire both Lotus Domino Messaging Server licenses and Lotus Domino Utility Server licenses, and support the combined capabilities of both licenses on the same hardware.

In some cases, a hardware vendor may ship a server with more processors than you actually ordered - on the assumption that you may want additional capacity in the future. Except when using virtualization capacity licensing, Lotus Domino server licensing is based on the physically available capacity. Note: at the time you activate the spare processors, you will need to acquire additional Lotus Domino licenses to reflect the revised total capacity on the system.
