Writing to disk

Hi Rusty,


You could use SMIT to determine the fragment size or use lsfs -q (man lsfs for more details)

Fragment size relates only to HFS. VxFS does not have fragments. According to the class notes from the HP Performance Class:

"A file system block is the minimum amount of data transferred to/from the disk when performing a disk I/O on an HFS file system. The default file system block size is 8KB."

"JFS allocates space to files in the form of extents, adjacent blocks of disk space treated as a unit. Extents can vary in size from a single block (1-KB in size) to many megabytes."

Hope this helps.
