Typical 3880 and 3990 installations have multiple proces- sors, most of them sharing access to the DASD sub- system and a large number of storage devices. ... More data must be shared and must be shared among more processors. Also, availability requirements make multiple connections essential between a DASD subsystem and any one processor. Connectivity. ...doi:10.1147/sj.282.0196 fatcat:djqg3wourzgctpqhq4m7s2ptve
The inclusion of the approach in a larger system model, as well as its relationship with previous work on DASD analysis is considered. Numerical results illustrate the accuracy of the method. ... The approach relies on a step-wise analysis of shared components within the data transfer path: head of string, control unit, channel, referred to as blocking points. ... Section IV briefly considers the embedding of the solution of a DASD subsystem model in that of a larger system model. ...doi:10.1109/tc.1983.1676256 fatcat:elzm7tofrjbj7hassoel4eg2tq

In general, the response time of a 3990 Model 3 with ESCON paths of 400 feet will be comparable to or slightly better than that of a parallel 3990 Model 3 with the same DASD con- figuration and workload ... Even a 3990 Model 2 can take advantage of DLSE mode: both storage paths within a multipath stor- age director would have to be busy before the 3990 would complete the I/O operation using the other cluster ...doi:10.1147/sj.311.0123 fatcat:o76wyrjvgjehzljabsrcfdgvya

As for the second setup, owing to the favored joint lighting and SE maximization, we solve a multi-objective optimization problem accounting for both objectives. ... Throughout this dissertation, we study the downlink of multi-user VLC systems with the aim of operation and architecture enhancement. ... Many works studied VLC channel modeling, it was found that the line of sight (LoS) component is significantly more powerful than the other multipath components. ...doi:10.25781/kaust-38v86 fatcat:lsm3zgkcxjflpa6yynztomwoz4
