Are containers like HP vPars or nPars?
Containers are not similar to either except in purpose: server consolidation. However, the differences include: • HP nPars and Sun’s Dynamic System Domains are similar in that both provide complete isolation of data, applications, and programs. A complete comparison of Domains and nPars is outside the scope of this document. • vPars are HP’s “soft” partitioning technology. vPars and Containers each enable multiple applications to co-exist in a set of hardware resources with some degree of isolation. • Each vPar is its own instance of an operating system, and must be managed separately. Each container is a virtual instance of Solaris, but there is only one copy of Solaris to maintain. • Containers are only available for Solaris 10. vPars only support HP-UX (versions ??). • All vPars share the same root password. Someone who gains root access in one vPar can do anything to any vPar. Conversely, each Solaris Container has its own namespace, including its own root account. Someone who gain
