Hello,

Some good news, benefits free for all.

After installing z/OS V2.2, we carefully converted some zFS-s from V4 to V5.
V5 should better tune the zFS traffic and give each system more autonomic 
access to the zFS, eliminating the need to route traffic through the 'owing' 
system.

Since we encountered no problems, we took the deep dive and added 
"converttov5=on" to IOEFSPRM with our last Sysplex IPL round.
The results were impressive:

-          A huge reduction in XCF traffic, in the IOEZFS Group by 99% and in 
the SYSGRS Group by 80%.

-          A substantial CPU reduction in the XCFAS and the GRS address space 
by a factor 2 - 3. This resulted in a noticeable reduction of the LPAR CPU 
consumption in some LPARs, mainly those LPARs that did not really use the 
zFS-s, but were designated as owner by ownership-automove because of IPLs of 
former owning LPARs.

As I said: it is free, grab it.

Kees.
