nxge interfaces too sensitive ?

Hi all,

I am writing this post in order to share my experience with the SUN nxge ethernet interfaces and try to see if some of you managed to solve similar issues than the ones we experienced here with T5520 running Solaris 10.

First, we noticed that it was somehow difficult to have those links working at 1Gbps.
After lots of tests and a call to SUN support, we configured the interfaces , by modifying the nxge.conf file so that the autonegotiation is switched on (mandatory if you want to reach 1Gpps) but the only speed advertized is 1Gbps/full-duplex.
Configuring e1000g interfaces is much easier: only activate autonegotiation and it works immediately at 1Gbps/full-duplex

Second issue, and for that one we are still looking for a solution, is the instability of those links when using them as heartbeat in a Veritas cluster environment.
We first blamed the Huawei switches that were connected at the other end and replaced those switches by simple hubs purchased at the supermaket. This was better as we did not loose completely both heartbeat links at the same time but still we sometimes see hb lost messages reported by Veritas.
We have configured the second heartbeat on a e1000g interface and this one never give any message.

Has anyone of ou experienced similar issue and if so, how did ou overcome it (solaris patches, modification of driver parameters, re-configuration at veritas level, ...) ?

Thank you in advance !
Fape

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris  exists  only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
