we have P8 850s, 870s and P9 950s with various amounts of memory between about 256 GB up to 4 TB memory and anywhere between 40 and 128 cpus. Not virtualized. A lot less adapters (usually 4 HBAs and 4 NICs - with Oracle 12c and 19 (thats at least what the DBAs tell us). We do not have GPFS but that should not make any difference for network realistically, only for IO. OS level for us is, and we have 2-node clusters.

CurveCP -- Message-handling programs SYNOPSIS
curvecpmessage [-q (optional)] [-Q (optional)] [-v (optional)] [-c (optional)] [-C (optional)] [-s (optional)] [prog] DESCRIPTION
This manual page documents briefly the CurveCP commands. A traditional UNIX-style server such as ftpd handles just one network connection, reading input from stdin and writing output to stdout. A "superserver" such as inetd or tcpserver listens for network connections and starts a separate server process for each connection. The CurveCP command-line tools have an extra level of modularity. The curvecpserver superserver listens for network connections. For each connection, curvecpserver starts the curvecpmessage message handler; curvecpmessage then starts a server such as ftpd. Then ftpd sends a stream of data to curvecpmessage, which in turn sends messages to curvecpserver, which encrypts and authenticates the messages and sends them inside network packets. At the same time curvecpclient receives network packets, verifies and decrypts messages inside the packets, and passes the messages to curvecpmessage; curvecpmessage sends a stream of data to ftpd. The same curvecpmessage tool is also used by curvecpclient. curvecpserver and curvecpclient can use programs other than curvecpmessage. Those programs can directly generate messages in the CurveCP message format without talking to separate tools such as ftpd; or they can support a completely different protocol that reuses CurveCP's cryptographic layer but transmits different kinds of messages. OPTIONS
How to use curvecpmessage: -q optional no error messages -Q optional print error messages (default) -v optional print extra information -c optional program is a client; server starts first -C optional program is a client that starts first -s optional program is a server (default) prog run this server SEE ALSO
curvecpserver (1), curvecpclient (1), inetd (8), tcpserver (1). AUTHOR
