70 -- SOFTWARE LICENSE AND SOFTWARE MAINTENANCE POC Charlotte Simpson tel: (410) 965-9496 This announcement was previously published under an incorrect classification code. Software License and Software Maintenance. The Social Security Administration is attempting to identify vendors who can provide an analytical modeling package to model its Headquarters Data Center. The Headquarters Data Center currently contains 1 - Amdahl 5990-1400, 1 - HDS EX-100, 2 - IBM 9021-900s, 2 - IBM 9021-860s, 5 - IBM 3090-600Js and approximately 4 terabytes of Direct Access Storage Devices (DASD) or about 2050 DASD. The analytical modeling package should process RMF, SMF, and TMON data to build the model, and it should support workload balancing, workload growth, LPAR tuning, I/O subsystem modeling, memory modeling, and performance problem identification and solution testing. Eight of the larger machines described above function as a single production environment, share approximately 1700 DASD, and support over 100 CICS regions. An acceptable modeling package could model the above production environment as a single entity and display the shared CPU and shared DASD effects. The modeling package would have the capability of reporting at the Data Center wide level as well as the physical and logical systems levels. The salient characteristics of a modeling package that would satisfy our needs would include the following: o process RMF, SMF and TMON data, extract necessary data and build the model o produce a single model of an environment which includes eight physical processors, shares 1700 DASD volumes, and supports over 100 CICS regions o have the capabiltiy to model the I/O sybsystem of the above environment and report the device utilization and response time effects o have the capability to model memory of the above environment (including central storage, expanded storage, and extended storage) and report the response time and CPU utilization effects o have the capability model workload growth on the above environment and report the response time and CPU utilization effects o have the capability to move workloads in the above environment from one physical or logical system to another and report the response time and CPU utilization effects o identify the constrained resource in all modeling scenarios o report results of all modeling scenarios at the data center, physical system, and logical system levels. o clearly report the effects of shared CPU and shared DASD in the above environment o contain embeded tables of performance characteristics for the current IBM plug-compatible CPUs and DASDs The responses must clearly state the ability to provide an analytical modeling package capable of satisfying the above stated requirements. Interested parties must respond to this notice within 15 calendar days from the date of this publication. Responses must be addressed to the procuring office below: Social Security Administration Office of Acquisition and Grants Attention: Charlotte Simpson 1710 Gwynn Oak Avenue Baltimore, Maryland 21207 Respondents should refer to Software License/CS. No open market award will be made on the basis of responses received; however, the information will be used in SSA's assessment of capable sources. The Government does not intend to pay for information provided. Requests for further information may be directed to: Wayne McDonald, Contracting Officer, (410) 966-1323. (0066)
