You're not a storage specialist ? You have absolutely no clue what IOS Queue Time (IOSQ), Pending Time (PEND) or Disconnect Time (DISC) means, but you hear these terms regularly when performance is being discussed. Then just go to the Hot Topics Site. There's a nice web article by Harry Yudenfriend "about the latest enhancements to I/O performance including FICON I/O operations and the IBM System Storage DS8000 solid state drive (SSD) technology". The article explains these terms and also indicates where new functionalities like zHPF, MIDAW . . . come into play.
As I always say, just check it out !
