Recommendation disclaimer

System recommendations are based on information available on the last updated date. They are published only as a guide and relate solely to Blackbaud software. Performance and response time are affected by many factors related to hardware (such as RAM, processor speed, and hard disk subsystem performance), network configuration (such as NIC performance, cable type, topology, operating system, parameters, and traffic), and the database (such as size, number of concurrent users, and the type of activities each user is performing).

In addition, network and workstation operating systems, third-party software products, and our own products are continuously updated with new features and options, which often place greater demands on hardware. Blackbaud recommends the purchase of top-of-the-line equipment when possible and that organizations budget for continual upgrades to their system. Blackbaud staff may provide limited informal guidance based on information made available. However, neither these system recommendations nor our staff’s guidance constitute a guarantee of compatibility, outcome, or performance. We encourage organizations to consult their own systems staff or outside technical experts to ensure appropriate results.

Note: System recommendations are subject to change. Before making any purchase or installation decisions, ensure you have the latest system recommendations and check for third-party compatibility information in Knowledgebase. If you use multiple Blackbaud products, refer to the system recommendations for each product; the total recommendations may be different from what is listed above. For additional assistance, contact Blackbaud Support.

Security recommendation

Blackbaud employs security best practices for all Blackbaud OnDemand systems, including the protection of all systems and information located at the Blackbaud Data Center, as well as communications between systems at the Blackbaud Data Center and client servers and workstations.

Although Blackbaud makes every effort to ensure the security of client data, it is imperative that organizations also employ security best practices at their site(s) and on their workstations.
