RE: Using SSD's



fixed

How many files, PF and LF are involved?
The PF will be much larger than the LF.
The LF may accessed more often depending on workload (read vs update vs write)
What is your biggest workload, (read, update, write)
OpsNav has additional info number of file accesses.
Do you have MPG installed, it would also help.

I would assume the PFs and they actually contain the data... but I know what 'ass- u-me' can do to you :)

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
