Hello, What Linux distro are you using? There are some common tweaks to the /etc/iscsid.conf and sysctl.conf files that help improve performance.
This link covers how to configure RHEL with EQL. The same principles apply to any recent Linux distro. http://en.community.dell.com/cfs-filesystemfile/__key/communityserver-components-postattachments/00-19-86-14-22/TR1062_2D00_LinuxDeploy_2D00_v1-2.pdf Most distros locate all the files under /etc/iscsi. RHEL/CentOS have some in /etc/iscsi and the rest in /var/lib/iscsi Are you using MPIO? What FW are you running on the EQL storage? A common tweak I run to help improve read performance is "blockdev". /sbin/blockdev --setra XXXX /dev/device This increases the read ahead value which is pretty low by default. It's covered in the PDF as well. Lastly have you opened a support case with Dell? They can review the diags and switch logs.
