Can DCX be monitored by ESRS Gateway without CMDCE

Hi JBG,

ESRS (EMC Secure Remote Support) Gateway is used by the EMC support teams to connect to the customer's devices. Whereafter a support personal may login to the device provided he has customer's permission to do so. Moreover there are authentications which he needs to pass through before he / she can log in. After logging in he / she may run commands and look for information he need etc etc. So in a way yes CMDCE is not getting involved, however if you mean that as a customer you may not need CMDCE for any kind of monitoring you do, because you have ESRS, would not be a right assumption.

The answer here isn't really clear to me and I'm not sure it fits what I know of ESRS.

To reword the question a different way (assuming I'm interpreting it correctly)... If a customer has DCX directors in an environment without deploying CMDCE, can ESRS pick up alerts and send them home to EMC and can a technician then connect back through ESRS to directly investgate through the management interface on the DCXs?

They certainly should be able to implement this.  With the ESRS Gateway you can configure switches two ways.  You either configure the managed object as the connectrix manager server or the switch itself.  In a setup where you have a conenctrix manager server and configure the SAN swtiches on a private network you point the ESRS at the connectrix manager server.  In a setup where the switches are on a public network you would point the connection to the IP of the SAN switch itself.

As far as sending files to the ESRS Gateway for failures it supports either FTP or SMTP so long as the switch can do either you should be able to send alerts to emc.

I would suggest you validate this with you local EMC account team as they own the setup of devices on the ESRS Gateway.

Hi,

Differentiating ESRS from call home, ESRS is used to establish a secure IP connection between the customer's environment and EMC, whereas call home is a message send by device intimating home, of its well being (or unwell being). For call home on DCX directors you need Connectrix Manager configured, and support also connects to Connectrix Manager to reach switch. However ESRS is used for many other devices than just DCX, it may be used for Storage boxes as well, depending upon how its been configured with those devices in customer's environment, it may point to the management interface such as CMDCE or to the device directly (once EMC support establishes a connection, support may initiate a telnet or a SSH session directly on the device). Call home may also be used without ESRS, using a modem connection.
