i got 1.2 gb/s on seagate sshd ST1000LX001 raid 5 x3 (but with the dreaded
cache array on) and 1.1 gb/s on samsung pro ssd 1tb x3 raid5 (no array caching
on for it's not compatible on proliant---not enterprise ssd).

hi, thanks for the reply. I have hardware raid 5 storage servers with 4TB WD
red drives. I think they are capable of 6GB/s transfers so it shouldnt be a
drive speed issue. Just for testing i tried to do a dd test directy into the
brick mounted from the storage server itself and got around 800mb/s transfer
rate which is double what i get when the brick is mounted on the client. Are
there any other options or tests that i can perform to figure out the root
cause of my problem as i have exhaused most google searches and tests.

your 10G nic is capable, the problem is the disk speed, fix ur disk speed
first, use ssd or sshd or sas 15k in a raid 0 or raid 5/6 x4 at least.

Hi , I have gluster 3.6.2 installed on my server network. Due to internal
issues we are not allowed to upgrade the gluster version. All the clients are
on the same version of gluster. When transferring files to/from the clients or
between my nodes over the 10gb network, the transfer rate is capped at 450Mb/s
.Is there any way to increase the transfer speeds for gluster mounts?
Our server setup is as following:
2 gluster servers -gfs1 and gfs2 volume name : gfsvolume3 clients - hpc1,
hpc2,hpc3gluster volume mounted on /export/gfsmount/
The following is the average results what i did so far:
1) test bandwith with iperf between all machines - 9.4 GiB/s2) test write speed
with dd
dd if=/dev/zero of=/export/gfsmount/testfile bs=1G count=1
result=399Mb/s
3) test read speed with dd
dd if=/export/gfsmount/testfile of=/dev/zero bs=1G count=1
result=284MB/s
My gluster volume configuration:
Volume Name: gfsvolumeType: ReplicateVolume ID:
