Objective and Definition

Researching the capacity of mainframe based Enterprise Computing Systems to achieve better system utilization and performance improvement.

The definition of Enterprise Computing:The set of computer technologies (i.e. hardware, software, and practices) used in integrated large scale systems, which are made up of a group of computational entities, including mainframes, servers, and peripheral devices, interconnected by a network forming a virtual centralized computing facility.

Objective and Definition (cont)

Enterprise Computing Supplemental Statements The hardware is distinguished by its resiliency with average failure

rates measured in decades. Software applications are usually distributed geographically and

organizationally and require standards for security and integration of heterogeneous components.

Established practices include continuous availability (no system down time), backup and disaster recovery, and strict data retention protocols.

Systems necessitate the integration and automation of large, complex and heterogeneous hardware platforms, operating systems, and network equipment and protocols. They can be used to remotely host applications from multiple businesses.

Often involves data processing and data mining on a vast scale (e.g. terabytes of data per day, billions of transactions per day) and thousands of simultaneous users.

Data retention and data integrity, reliability and disaster recovery, and other legislative and governance requirements are essential in enterprise computing environments.

Virtualization and Virtual Machine

Virtualization is a broad term that refer to the abstraction of a computer resources. It does not hide implementation details like abstraction, instead it provides a mapping between “real” resources and virtualized resources.

Grouping virtualized resources to form a computation device, the group of resources is called a virtual machine (computer).

System Support Projects on ITK Enterprise Computing System

z890 System Configuration Objective: Supports Enterprise Computing education, research, and develop

ment in activities ITK. It will provide teaching and learning environment for ECS and ECS related courses and facilities for benchmark, application, performance testing/improvement, and other research projects.

System Setup: There will be two Logical Partitions) LPARs, one for general use and the other for testing. z/VM, z/OS and SuSE Linux will be the primary operation systems run on the two LPARs.

Status: Construct system support structure. Team Member: Min Jiang, Paul Propell, Ryan Hull

ECS Development Network Infrastructure Objective: Construct an integrated learning and development environment to

allow people concentrate their work under various situation. System Setup: Based on the reliability, security, flexibility, and supportability,

Linux O/S is used to build a network working environment. Different version of Linux have been installed on different platforms. Networking clients to server allows multiple Mainframe consoles present, fileserver with failover provides a secure working environment, and version controlled domain controller eliminates the inconstancy of collaborative development.

Status: Under construction Team Member: Keshab Budhathoky, Niranjan Sharma, Sandeep Basnet

Projects on ITK Enterprise Computing System

Linux/Unix/AIX Course Development Objective: a series of two Linux/Unix courses in line with the Enterprise Comp

uting Systems program at Illinois State University (ISU). Setup:

Course I – Introduction to Linux/Unix-AIX Operating Systems Course II –Enterprise Linux/Unix-AIX System Programming and System Administra

tion. Status: Completed draft course outlines with IBM and State Farm. Waiting for

the arrival of P520 Team Member: Chu Jong, Kyoungwon Suh, Glen Sagers

Kuali Open Source Porting to zSeries Objective: Port the Kuali Financial Services (KFS) package to Linux on the z8

90 platform using Websphere and DB2, examine various performance and quality of service issues associated with the package. KFS shares a common framework and fundamental set of services with Sakai; an open-source community based learning system that is comparable to Blackboard. Goals include porting Sakai to Linux on the z890 system and and feasibility testing of the Sakai software package.

Status: Install Kuali in SuSE under x86 platform, plan to move to z platform Team Member: Andrew Justi, Chu Jong.
