HP Flex 10 - Received Dropped Packets

VMware Community,

We are having a strange issue, which so far VMware/HP support has not been able to solve.

We have an environment where we are using 2 x 10GBps and 2 x 9Gbps adapters on a single DVS.

The DVS supports ESxi Management, vMotion, and Data traffic for the VMs.

We have Resource allocation turned on as well.

The blades are G7s.

Our problem is we are constantly seeing dropped received packets in this cluster. After a lot of research we thought it may be firmware/driver related and went down a whole path of updating our chassis, hosts, drivers, etc to the latest supported config by HP.

Still we are getting dropped received packets. We can recreate it quite easily, by initiating a vMotion.

We've tried running on just the 2 x 10gig and just the 2 x 9gig adapters but this made no difference.

Anyone got any suggestions?

Nick

The information I posted on my blog is awfully out of date.

Please use the information found in the "February 2015 VMware FW and Software Recipe" available at:

http://vibsdepot.hp.com/hpq/recipes/Feb2015VMwareRecipeSPP201409_16.4.pdf

For the BL460 G7 for example, with the NC553i CNA and ESXi 5.1, you should use the following:

Driver : 10.2.293.0.-1OEM.510

Firmware:10.2.340.19

Many thanks ragmon for the clarification.

Yes, I can see it from the Recipe page that for my HP BL 465c G7 running HP NC551i Dual Port FlexFabric 10 Gb Converged Network Adapter I must be using:

update the firmware to 4.9.416.2

update the driver to 10.2.293.0

But somehow there is no Official HP Advisory page or VMware KB article to support the idea offirmware upgrade.

I need to convince the management team and the implementation team regarding this Firmware update but still I cannot find the supporting KB article for that apart from this generic blanket statement: VMware KB: Performance issues with HP NC55x Network Adapters in which my adapter firmware is more recent than the one suggested in the KB article.

The VMware KB that you have mentioned is out-of-date and therefore not relevant anymore.

I would justify the firmware/driver update by using the following HP advisory:

http://h20566.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c04218016&sp4ts.oid=4145106

You can update the firmware by:

1. Using the offline update utility: Drivers & Software - HP Support Center. </title><style>ul.breadcrumbs-custom, o...

2. Using online update file:  http://h20565.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=5033634&swItemId=MTX_1eed76932a9946baad82...
