Completed project: Active Directory refresh

Primary UITS contact: Matt Martin

Completed: June 14, 2013

Description: Active Directory Services (ADS) is a collection of resources that includes, but is not limited to, user accounts, computer objects, and other Active Directory objects. It also provides account authentication services for services like IU CAS. The domain ads.iu.edu is the primary domain in the Indiana University Active Directory, driven by the Windows Server operating system.

The Messaging Team will be upgrading the hardware and software used to provide the Active Directory service.

Benefits: ADS is an extremely I/O- and CPU-intensive environment requiring high-performance hardware. Upgrading to faster, eight-core CPUs and solid state drives and adding servers will provide the necessary resources to meet current demands and allow growth for the future. The proposed solution will more than double the number of CPU cores (each with increased clock speed), improve I/O operations by using solid state drives and larger controller cache, and add memory for growth of the directory.
