Woops – No Redundancy
A commercial bank had an installation with three enclosures incorporating a stacking link configuration. As the bank cannot afford any interruption in service, MagicFlex was brought in to analyze the configuration to discover any potential issues before interruptions in service were noted.
MagicFlex analysis quickly identified that no redundancies were present in the Virtual Connect server profiles. This lack of redundancy means that should one of the servers in the enclosure be in maintenance mode or partaking in an upgrade procedure, all the servers within that enclosure would fail to relay traffic.
MagicFlex’s proactive configuration analytics helped the bank correct the configuration to configure redundant servers and thus enable an outbound path.
Where it's not
A financial institution was experiencing difficulty with its Linux clusters, noticing slow traffic and numerous disconnections, resulting in customer complaints as they were unable to access their applications.
IT went through their troubleshooting checklist, but were unable to identify the cause of the issue so they began to look at the network. At 2 a.m. (when else?) they opened a ticket for the network administrators but eight hours later they still were no closer to solving the issue. The connections from the NICs to the backbones appeared to be just fine.
MagicFlex was installed and within minutes identified that the network was running smoothly. The administrators then focused on system issues and discovered that the problem was in the database services. They restarted the servers and traffic resumed correctly.
In this case, MagicFlex did not identify the issue, but eliminated the red herrings so that IT could troubleshoot effectively and discover how to solve the problem.
Where’s the VLAN?
Here’s an incident where MagicFlex was able to provide the alert that identified where a disruption was occurring.
This customer’s configuration included a number of c7000 enclosures and FlexFabric. A WMware server was installed in one of the enclosures. One specific virtual machine was configured with a vSwitch with VLAN ID 1, 2 and 3.
However, in the Flex configuration, only VLAN 1 and 2 were configured and VLAN 3 was missing. When the virtual server that was configured to send and receive traffic using VLAN 3 tried to send traffic, no traffic could pass, the server did not respond to a simple ping.
MagicFlex was brought in to discover what could be causing this problem. An analysis of the configuration identified that VLAN 3 was missing in the Flex definitions.
The company was then able to correct the settings and the traffic flow resumed.
