Blackboard Learn Release 9.1 Configurations for Dell

Configurations for Dell
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 with 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 with connected classroom initiatives fall into this category. Customers with larger community sizes (greater than 250,000 users) fall into this category.

64-bit Memory Requirements  Per OS Instance 8GB to 16GB recommended 8GB to 16GB recommended 8GB to 16GB recommended
I/O Workload at Peak Hour 300 to 500 I/Os 500 to 1000 I/Os 1000 to 2000 I/Os
Hits/Hour at Peak Hour Up to 4 Million Hits/Hour Up to 8 Million Hits/Hour Up to 12 Million Hits/Hour
Characteristics With 4 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. With 2 CPU threads per instance and a 32-bit deployment across 4 instances, this configuration will support approximately 2,000 concurrent sessions.

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.
