Systat disk read numbers

harold — Thu, 05 Jun 2025 07:21:38 GMT

My customer added PAM cards .My customer is noticing that disk read KB/s and network out KB/s are about the same on sysstat as before , even when PAM shows significant savings for disk reads – are the disk reads reflecting reads from disk _and_ PAM (hence the disk read KB/s being higher than network even with PAM on), or is it that the disk reads would have been higher?

Any repsonse is greatly appretiated.

In what mode is the PAM being used? meta only, low_pri or mixed?

PAM card is being used in Normal mode, which should be mixed IIRC.
