Trouble is that there is no unofficial option/answer to this question. The problem is in the transfer of large files, include the upgrade image during NDU and the creation of regular debug logs which are then uploaded to EMC via SYR or ConnectEMC. By limiting the link rate to 100Mb, timeouts may occur which impact NDU and log creation/collection. Unofficially, as long as the link is healthy (no errors), all other mgmt. functions should not be impacted by the lower link rate but why take the risk?
Hi All, have a question that I'm hoping the community can help answer.  Customer networking team configured the XMS and Storage Controllers at 100Mb Full duplex  and the health checks (pre-upgrade) have flagged this.   Support have provided the article that discusses this with recommendations to change to 1000Mb. Also that the site install doc states all interfaces at 1000Mb. Customer network switches within the define zone are not capable of this, however there may be an option to move only the Storage Controller interfaces into the Prod Zone and firewalled.  Question I have is if the health check script only checks for the SCs at 1000Mb or also the XMS? It seems to initially fail at the first SC. From your experiences, is there a requirement for the XMS to also have that speed?  Thanks for your time, Daniel
