Operating Systems AIX ISCSI poor performance 1.5MB/s fresh install AIX7.1 Post 302977101 by Scrutinizer on Tuesday 12th of July 2016 02:51:36 PM

This probably has to do with your block size. The transfer is limited by the number of (small size, 512-byte) IO's rather than the Megabytes..

What happens when you do
Code:
dd if=/dev/hdisk1 of=/dev/null bs=1024k

?


---
And also, what happens when you run two such dd's simultaneously?

NAME
scconf_transp_adap_e1000g - configure the Intel PRO/1000 network adapter DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. You can configure e1000g Intel PRO/1000 network adapters as cluster transport adapters. These adapters can only be used with transport type dlpi. The e1000g based network adapter connects to a transport switch or to another Ethernet adapter on a different node. In either case, the connection is made through a transport cable. When a transport switch is used and the endpoints of the transport cable are configured by using scconf, scinstall, or other tools, you are asked to specify a port name on the transport switch. You can provide any port name, or accept the default, as long as the name is unique for the switch. The default is to set the port name to the node identifier that hosts the adapter at the other end of the cable. There are no user configurable properties for cluster transport adapters of this type.
