Recommendations for Empower Enterprise deployment in a Wide Area Network (WAN) - WKB13163

ENVIRONMENT

• Empower Enterprise
• Wide Area Networks (WANs)

ANSWER

Guidelines for Empower global WAN deployments:

Architecture:
·    Empower Database and Citrix Servers should reside in the same data center.
·    A DNS server should be accessible to the LAC/E for quick domain name resolution and domain authentication.
·    Use a local TNSNAMES.ora file in place of a global TNS_ADMIN variable.
·    Consolidate Empower licenses to reduce the number of entries.

Wide Area Network parameters:
·    Bandwidth - ensure that sufficient network bandwidth is available to support all Empower traffic, as well as any other network traffic within the same network.
·    Latency - 200 ms maximum latency (spikes will cause performance degradation).
·    Packet loss - any packet loss will cause significant performance degradation.
·    WAN optimizers - we do not support the use of WAN optimizers and, if they are in use, exclude all Empower network traffic.

NOTE: These parameters were not evaluated for instrument control and data acquisition.
