3. 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.

4. 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.

5. 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).

6. Abstraction v.s. VirtualizationIEEE Computers, May 2005 • Abstract hard disk details using variable file sizes • Virtualizes a large disk into two smaller virtual disks

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
