Hello, For our cluster I've tried different Cluster File System. GlusterFS I noticed positively by its simple configuration. This is my setup: GlusterFS Server: Dell PowerEdge R630 + MD1200 Debian: 8.4 GlusterFS: 3.5.2 Network: Infiniband Create the volume (Distributed Volume): gluster volume create home-vol transport tcp,rdma \ gluster01.ib.cluster:/srv/glusterfs/home/brick1/brick On the same setup I have previously placed an NFSv4 server and made various measurements. In comparison, GlusterFS performs very poorly. Is it possible with GlusterFS to reach the bandwidth of NFSv4? These are my measurements: NFSv4: dd if=/dev/zero of=/mnt/gfs/home/benchmark bs=1G count=1 oflag=direct 706 MB/s dbench -D /mnt/gfs/home -t 1800 10 Throughput 241.034 MB/sec 10 clients 10 procs max_latency=25.370 ms GlusterFS: dd if=/dev/zero of=/mnt/gfs/home/benchmark bs=1G count=1 oflag=direct 356 MB/s dbench -D /mnt/gfs/home -t 1800 10 Throughput 45.1128 MB/sec 10 clients 10 procs max_latency=50.154 ms Thank you very much, Klemens -- Klemens Kittan Systemadministrator University of Potsdam Institute for Computer Science August-Bebel-Str. 89 14482 Potsdam Tel. : +49-331-9773125 Fax. : +49-331-9773122 Email : klemens.kittan@xxxxxxxxxxxxxxxxx XMPP : kittan@xxxxxxxxxxxxx gpg --recv-keys --keyserver pgp.mit.edu 6EA09333
