Re: Using SSD's



fixed

It depends.

Sorry but as far as I know, it all depends on how things are used.

If you have performance explorer or iDoctor(?) you could dig into the reads
and writes for specific items.

The DB surfaces also surfaces some stats but they are reset at IPL
Available via:
Display file description (DSPFD)
Application programming interface (API) QUSRMBRD
System i Navigator Health Center
SQL catalog queries

We recently installed 8 SSD on our system.

These units are in the same iASP as several older HDD’s.

We can’t allocate all of our “HOT” files to the SSD’s because of space
limitations.

If I had to choose between locating Physical File data or the Logical File
indexes built over this data on SSD, which type of file would provide the
best performance boost being located on SSD, the PF’s or the LF’s
