Hi, since about 3 months we are using striping for all our vsam volumes of TSM 3.7.4.0 at OS/390 2.10. (storagepools, database, log) We use the maximum size for TSM vsam datasets of 4 GB and spread each of them over 16 volumes of type 3390 model 3, some datasets are spread over model 9 disks. It seems that the response to sql queries is about 30 % faster. Restores from storagepools of large files show no limit of a single host volume (when cache is exhausted). (The disk are placed on an old RVA storage system of ESCON.)
