Directory Server and Scalability

Directory Server provides for both vertical and horizontal growth without major deployment redesign. This level of scalability becomes increasingly critical as deployment grows.

Depending on the hardware, Directory Server can provide sustained search performance of 20,000 entries per second on a single machine and horizontal scalability to several thousand searches per second. For information about how to deploy Directory Server for read scalability, see Chapter 10, Designing a Scaled Deployment, in Oracle Fusion Middleware Deployment Planning Guide for Oracle Directory Server Enterprise Edition.

The requirement to store and update information constantly increases with the expansion of use across the organization. Update performance of Directory Server is close to relational database-write performance. For information about how to deploy Directory Server for write scalability, see Chapter 10, Designing a Scaled Deployment, in Oracle Fusion Middleware Deployment Planning Guide for Oracle Directory Server Enterprise Edition.

Directory Server provides linear CPU scalability to up to 28 CPUs for “read from cache” operations. It allows access to maximum memory capacity and delivers high performance that accommodates large directories on a single system for maximum hardware benefit.
