Yes, will write to both gluster nodes simultaneously.

I'm getting confused, 120 mb/s is less that 20 MB/s unless you mean
120MB/s?

No, is real speed. From any computer linux or esxi if I write via NFS with dd
utility I have this speed. But if I try to write to one raw file like esxi does
in vmdk, than the speed drops to 20-40mb/s. So my issue is low speed when I
write into raw image file (using losetup and DD on linux , or
If I write with DD in linux locally to the same cluster node... or via network
I have 120MB/s. the full speed of te 1 Gbps.But if I write to an RAW Image
File... like vmdk in vmware... I have average of 20-40MB/s only.

I also tried more gluster version but the same situation.If I use iscsi for
example to export a raw image... I have 120MB/s write speed.

I believe if this is replica 3 then you would expect 40 MB/s, as the client
has to write to 3 bricks. You only mentioned 2 servers so I assume this is
at most replica 2, so 60 MB/s would be what I would expect. This is still
1.5-3x the numbers you are reporting though.

Hi,
I have 2 server with centos 7 and I want to make a replicate storage cluster
for the esxi.In both server I have 4 disk in raid 5 mdadm. The write speed on
that device is ~250-300MB/s all the time.I create xfs file system on the mdadm
and I exported that gluster volume via native fuse nfs v3
I use Vsphere and I have replica 2. I share the image via gluster nfs-fuse.I
have 2 dedicate LANs one to esxi and another for gluster cluster replication
thats why I have 120MB/s when I create a new file onto the gluster cluster. But
when I try to use that file like vmdk, the speed drops to

iSCSI over gluster?

Not sure, bit

What VM hosting are you using? KVM/Qemu? vSphere?
How is the image shared
Yes, now I install the 2 new Slackware machines and I want to setup gluster +
iscsi. I hope that will work as I expected. Do you know to be some issues if I
use multipath to the both gluster servers from esxi?
