Introduction
Figure 4 Engine components
Fibre Channel COM
switches
Provide highly available connectivity among the directors in a dual-engine or quad-engine cluster.
Uninterrupted power
supplies (UPS)
Provide backup power to the COM switches and management server in a dual-engine or quad-engine
cluster, allowing the connected components to continue operating through a power loss of up to 30 seconds.
Management server Provides management to the other components in the cluster, and provides an interface for access from a
remote management station.
Management server functions include:
• Hosting VPLEX software.
• Providing an interface between the customer and the VPLEX cluster.
• Generating Call Home events.
• Enabling secure management between clusters in a Metro-Plex.
• Protecting the internal management network from the customer LAN.
• Providing access to VPLEX components for field-replaceable unit (FRU) replacement procedures.
• Facilitating nondisruptive upgrades (NDU)
