I am currently running into an issue, so i'm posting to this group to see if 
anyone has any solution for me on this issue.

I am running z/VM 4.4, SLES 8 and SLES 9 64 bit, with hipersockets on each 
guest.
currently we have two hipersockets defined per guest, one with 64k mtu block 
size and one with 8k mtu block size. We use the one smaller mtu size 
hipersocket to talk among the other guests from guest to guest and to do 
authentication to a USS LDAP server under MVS. The 64k mtu block size 
hipersocket is being used for backups through fdr upstream on the mvs side and 
notice a nice improvement on speed for backups. The problem we are running into 
is the 127 device limitation. we figure if we keep going the way we are we will 
only be able to have about 20 guests, and our future plans out stretch this to 
more than 40 and 50. We also thought of just useing the one hipersocket that 
had the large mtu just for everything and have one hipersocket per guest, and 
we figure we can get about 40 guests if we go that route, but still we want 
more than 40 guests eventually. Does anyone have a solution for this? What is 
everyone else doing? Is there a work around for this issue we are running into? 
Suggestions much appreciated.
Thanks,

Cameron Seader
