work on adding it to the FAQ.</font><br><br><font size=2 face="sans-serif">But, in general:</font><br><font size=2 face="sans-serif">1. The maximum number of "outbound

limited to 31 ( 32 including the local cluster)</font><br><font size=2 face="sans-serif">2. The maximum number or "inbound
cluster" - meaning "how many clusters can join my cluster) -
is not really limited. Thus, since the smallest cluster possible is a single
node cluster, it means that 16383 nodes can join my cluster ( 16384 - 1).</font><br><br><font size=2 face="sans-serif"><br>Regards,<br><br>Tomer Perry<br>Scalable I/O Development (Spectrum Scale)<br>email: tomp@il.ibm.com<br>1 Azrieli Center, Tel Aviv 67021, Israel<br>Global Tel: +1 720 3422758<br>Israel Tel: +972 3 9188625<br>Mobile: +972 52 2554625<br></font><br><br><br><br><font size=1 color=#5f5f5f face="sans-serif">From:

Spectrum Scale (GPFS) FAQ - Maximum number of remote clusters accessing

appreciated.</font><p><font size=3>My new question:</font><p><font size=3>i have currently with IBM a discussion about the maximum
number of remote clusters mounting GPFS from a local cluster.</font><p><font size=3>The answer was that there is almost no limit to the amount
of REMOTE clusters accessing a given cluster. From memory I thought there
was a limit of 24 remote clusters and the total amount of node must not
exceed 16k nodes. The later is described in the GPFS FAQ but about the
maximum number of remote cluster accessing a local cluster I could not
find anything within the FAQ.</font><p><font size=3>So is there a limit of remote clusters accessing a given
GPFS cluster or could I really have almost 16k-n(*) remote clusters ( One
node cluster ) as long as the max amount of nodes does not exceed the 16K
?</font><p><font size=3>(*) n is the amount of local nodes.</font><p><font size=3>Maybe this info should be added also to the FAQ ?</font><p><p><font size=3>Info from the FAQ:</font><p><a href=https://www.ibm.com/support/knowledgecenter/SSFKCN/com.ibm.cluster.gpfs.doc/gpfs_faqs/gpfsclustersfaq.pdf><font size=3 color=blue><u>https://www.ibm.com/support/knowledgecenter/SSFKCN/com.ibm.cluster.gpfs.doc/gpfs_faqs/gpfsclustersfaq.pdf</u></font></a><p><font size=3 face="Arial"><b>Q5.4: What is the current limit on the
