Blackboard Learn no longer supports application servers running Solaris. For more information, visit Behind the Blackboard. This information is provided as a guideline and review of third party hardware specifications should be made before final hardware acquisition.
Guidelines for Linux and Windows based installations may be found in Learn Hardware Configurations.
| Sizing Category | Standard | Advanced | Complex |
|---|---|---|---|
| Description | The Standard sizing configuration is designed for availability and performance. Options exist for both physical distributions of application servers and/or virtualized instances of the application. The institution has minimal deployment of distance learning or connected classroom initiatives (less than 5%). | The Advanced sizing configuration is designed for high-availability and high-performance. The model is designed for heavy adoption of the product across institutions of varying sizes. Customers deploying distance learning programs or have connected classroom initiatives to a portion of the community fall into this category. | The Complex sizing configuration is designed for massive adoption, high-availability and high-performance. Customers deploying predominately distance learning programs or have connected classroom initiatives fall into this category. Customers with larger community sizes (greater than 250,000 users) fall into this category. |

| Characteristics | With 8 CPU threads per instance and a 64-bit deployment across 4 instances, this configuration will support as many as 20,000 concurrent sessions for a peak hour. A concurrent session is a user who has logged into the application within the last hour. Results will vary depending on the use of memory intensive areas of the application such as Assessment and Grade Center.Memory has the greatest impact on the session concurrency and responsiveness of the application, followed by CPU capacity. Consider a larger memory footprint for even smaller workloads to deliver faster page responsiveness. |
With 16 to 20 CPU threads per instance and a 64-bit deployment across 6 instances, this configuration will support as many as 40,000 concurrent sessions for a peak hour.
