Originially when Equallogic was released to the market, they were their own company but eventually purchased by dell and since we have seen a change, some for the better some for the worst. Articles such as this one pretty much spell out that bonding helps if your aggregate throughput exceeds that of a single NIC vs. Your longer-term goal should be to find newer storage options, though I fully understand this isn’t often easy or cheap one of my pools still is tied into an EqualLogic! Configuring a management interface or secondary interface on a bonded network provides resilience. Extract the MEM so that it resides in a C: What you might be experiencing are behavioral changes that perhaps vSphere made between 5.

Click the Targets tab, and click a target volume that has a status of Connected to mpioo and select that target. See my edited answer for an example config that would accomplish what you’re mio. For both Round Robin and Least Queue Depth policies, sessions to the Group member containing the data are given preference over other sessions.

Are you mixing jumbos and standard frames on those vSwitches? We are working on a fix.

If you are equuallogic LVM then as Tobias says change the configuration in the Equalogic to reflect the connection type you want to use. This will walk you through a series of variables you need to enter. Leave a Reply Cancel reply Enter your comment here What a shame, because the MEM gives you optimal performance of vSphere against your EqualLogic array, and is frankly easier to configure. Equalloguc also depends on the storage plugin type you are using with your SRs.

Go back to the newly created Volume — Access — Add basic access point. You’d need to use two vSwitches – one for each physical NIC: In our case, I believe we went to multipathing.

Can you explain how to correct this error? Use the pull-down menu underneath Load Balance Policy to configure the policy for this device. Reality Extractor 1, 1 13 This would simulate the configuration “expected” by the EHCM MPIO driver, and give you the desired load balancing and session management behavior and hopefully performance benefits. Mind if I bounce a couple questions off you? The tool can be configured in a number of different ways to accommodate all types of scenarios; all of which is well documented in the Deployment Guide.

In practice, unless yu have a super busy network, you probably won’t exceed the throughput limit of a single NIC, mlio particular with 10 Gb or faster NICs: Take a look at other influencing factors. I had considered mentioning that VUM could be used as well, but was really trying to keep it simple for the reader and relatively short post.

Multipathing in vSphere with the Dell EqualLogic Multipathing Extension Module (MEM)

If you are using the “EQL” type plugin do not use multipathing with it. As Tobias mentions multipath gives you double the bandwidth. The extension module only helps you if you are using iSCSI with the host itself. If you view the sessions tab, be aware that the MPIO DSM equallofic not use multiple connections per session, therefore the Load Balance Policy setting accessible through the Connections button has no effect.

Interesting, so what you are saying is that Dell’s MPIO could actually reduce performance in my current setup? The guest performance charts in vCenter show corresponding latency and usage in the advanced Disk performance.
