JFS: Max IO ?

[Raj Patel_1]

Can anyone confirm what the maxio is for a JFS filesystem? I thought it is 128kb on HP-UX 11 64 . Any ideas ?

Max IO ? Im not sure what you mean by this. A JFS filesystem can have a blocksize from 4k-32768k, but this is not Max IO. The maximum amount of IO that a filesystem can handle is down to how fast your disk subsystem is.

Hi,

Yes the maxio size is 256k on HP 11.0.
You can search Metalink for key words
"256k, hp, db_multi_block_read_count" to find similar information.
