<div dir="ltr">Hi Everyone,
<div dir="ltr"><br>
</div>
<div dir="ltr">In the world of GPFS 4.2 is there a particular advantage to having a large amount of memory (e.g. > 64G) allocated to the pagepool on combination NSD Server/FS manager nodes? We currently have half of physical memory allocated to pagepool on
these nodes. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">For some historical context-- we had two indicidents that drove us to increase our NSD server/FS manager pagepools. One was a weird behavior in GPFS 3.5 that was causing bouncing FS managers until we bumped the page pool from a few gigs to about
half of the physical memory on the node. The other was a mass round of parallel mmfsck's of all 20 something of our filesystems. It came highly recommended to us to increase the pagepool to something very large for that. </div>
<div dir="ltr"><br>
</div>
I'm curious to hear what other folks do and what the recommendations from IBM folks are. <br>

Thanks,
