EMC has created an eRoom Sizing Tool with related documentation that helps customers with the eRoom deployment sizing process. EMC strongly recommends that eRoom Administrators read and understand the provided documentation, run the eRoom Sizing Tool and review its results, perform the eRoom 7.4.3 upgrade to a test or staging environment, and complete thorough performance testing in the test or staging environment prior to a production upgrade. Failure to complete these steps may lead to an unplanned eRoom 7.4.3 outage. Refer to EMC ETA esg112401 for the details.
