AW: Show of Hands, TSM on Mainframe, Using STK 9840 Drives in 359 0 Im age Mode

Moin Bernie,
we changed for 3 weeks our 9840 drives from 3490 mode to 3590 mode and
reduce the cpu-util by 30-50 % !
in time i don´t know what you mean with the using of LBI
(LargeBlockInterface) ?
since os/390 > 2.10 and tsm >= 4.2 tsm and device-type = 3590 tsm will write
256KB Blocks per i/o
(by 3490 it was 32KB).
i can say : it is running fine.

Looking for users of STK 9840 drives with mainframe TSM, running in 3590
