Quickref has it (item 3390DASD). I would expect it is available on the IBM web site but I don't have very much luck when I use their search feature.
A blocksize of 605 will result in 45 blocks per track which results in slightly less than 50% utilization. Your primary is 104 tracks and your secondary is 13 tracks. 121 byte blocks result in 75 blocks per track -----Original Message----- From: Charles Mills [mailto:[EMAIL PROTECTED] Sent: Friday, June 16, 2006 10:13 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Track capacity? Where can I find 3390 track capacity tables or formulas? I haven't done this in so long I think the last time I did this it was for a 2314. Specifically, I am trying to figure out: - If the DD statement says SPACE=(605,(4640,580)) how many tracks will have been allocated (primary and each secondary)? - If the program actually wrote 121-byte blocks (yes, I know) how many of those would fit on a track?
