Subject: [PATCH v1 0/5] NFSv3 client RDMA multipath enhancements
Date: Thu, 21 Jan 2021 21:10:15 +0200 [thread overview]
Message-ID: <20210121191020.3144948-1-dan@kernelim.com> (raw)
Hi,
The purpose of the following changes is to allow specifying multiple
target IP addresses in a single mount. Combining this with nconnect and
servers that support exposing multiple ports, we can achieve load
balancing and much greater throughput, especially on RDMA setups,
even with the older NFSv3 protocol.
The changes allow specifing a new `remoteports=<IP-addresses-ranges>`
mount option providing a group of IP addresses, from which `nconnect` at
sunrpc scope picks target transport address in round-robin. There's also
an accompanying `localports` parameter that allows local address bind so
that the source port is better controlled in a way to ensure that
transports are not hogging a single local interface.
This patchset targets the linux-next tree.
Dan Aloni (5):
sunrpc: Allow specifying a vector of IP addresses for nconnect
xprtrdma: Bind to a local address if requested
nfs: Extend nconnect with remoteports and localports mount params
sunrpc: Add srcaddr to xprt sysfs debug
nfs: Increase NFS_MAX_CONNECTIONS
