Export configurations

Multihop configurations, in which the exported VOB and export view are not located on the same host, should be used only when there is no alternative.

About this task

Accessing data from a non-VersionVault host can involve three hosts:
  • The host on which the VOB resides
  • The host on which the export view resides
  • The non-VersionVault host

A multihop configuration, in which the VOB and its export view reside on different hosts, requires MVFS-level communication, which is slower than NFS communication, between the two HCL VersionVault hosts. In addition, a multihop configuration introduces the possibility of access cycles, in which two of the hosts depend on each other for network-related services, or such a dependency is created through vendor hosts. Such situations may result in time-outs (if VOBs are soft-mounted) or deadlocks (if VOBs are hard mounted).
