we have new Dell Servers with Dell's VMware ESX 6.5 installed. They have multiple 10GB interfaces.
With NFS we get expected speed, basically to flood the disks up to their limits.
However, with iSCSI the network becomes the bottleneck, we only reach 20% of the possible performance.
How many clients are using it? Do you have problems when all 10GB interfaces are in use or do they also occur when only 1 interface is in use?
We installed Ubuntu 16.04 on one of the servers, for testing. With Ubuntu we are able to run iSCSI properly.
Why not just run Ubuntu then? What does ESX give you that Ubuntu + Xen or KVM doesn't? Do you have any advice on affordable 10GB gear? One of my clients has been holding off on 10GB for financial reasons. Give me some good advice on affordable 10GB and I might be able to help you with 10GB performance tuning a month later. ;) -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
