OpenVMS Clusters vs Microsoft "Wolfpack"?

» close window

The Question is:

 
I have read most of the FAQ's regarding VAX/VMS and NT integration.  I got
mixed information.
 
Does DEC/Compaq have an clustering product for VMS and NT platforms?
 
Thanks
 

The Answer is :

 
  The OpenVMS Cluster capabilities are presently roughly a decade more
  advanced than the Microsoft "Wolfpack" model.
 
  OpenVMS Clusters allow storage to be shared -- for write access -- by
  applications running across up to 96 nodes, and entirely in parallel.
  Microsoft "Wolfpack" permits exactly one node to access the disks at
  a time, and the disks can be failed over to the standby node.  No
  shared access is permitted.
 
  OpenVMS Clusters coordinate operations using a fully distributed lock
  manager.  Both the operating system and applications can take advantage
  of the lock manager for tasks ranging from the obvious case of file
  access to a distributed application scheme used to coordinate the plowing
  of snow, the loans of books in a library, or the picking of oranges.
  Microsoft applications completely lack this, often resorting to the
  creation and deletion of small "marker" files.
 
  OpenVMS and Microsoft Windows NT can operate together in a Microsoft
  COM or SMB environment, as well as via industry standard protocols such
  as NFS and TCP/IP.
