HP DCN Infrastructure Requirements and Recommendations
In order to make use of the HP DCN, the data center environment must meet some key requirements as described in the following sections.
Data Center IP Network
HP VSP can be used in any data center with an IP network. HP VSC actively participates in the IP routing infrastructure. HP VSCs can run OSPF or
BGP is used to form a federation of HP VSCs and synchronize the HP VSP network information. In addition, BGP is also used to exchange routing information with the data center provider edge router.
NTP Infrastructure
Because HP VSP is a distributed system, it is important that the different elements have a reliable reference clock to ensure the messages exchanged between the elements have meaningful timestamps. HP VSP relies on each of the elements having clocks synchronized with NTP.
The HP VSD and HP VRS applications rely on the NTP facilities provided by the host operating system. The HP VSC, which is based on HP DCN OS, has an NTP client.
HP recommends having at least three NTP reference clocks configured for each system.
Domain Name System
In scaled HP VSP deployments, the HP VSD functional elements can be distributed across machines into clusters of machines where the failover and load sharing mechanisms for the clusters rely on being referenced as a single DNS entity.
Certificate Authority
The northbound ReST API on HP VSD is accessed within an SSL session. The HP VSD is able to use a
HP DCN Installation Overview
Installing HP DCN consists of installing the three software components (HP VSD, HP VSC, and HP VRS) and configuring their interfaces to establish connectivity between them.
