fault tolerant shared storage

Shared Storage Application servers require fault-tolerant shared storage in order to facilitate initiated and uninitiated shutdowns. Organizations must choose a shared storage solution and will need to implement the shared storage API to integrate with PEGA 7. PEGA 7 supports shared storage using NFS or shared disk out of the box, but these solutions are not inherently fault tolerant.

Can some one suggest what we need to use for fault tolerant shared storage?

Hi,


  • For NFS solutions, the shared storage must point to an NFS location to support access from all nodes.

  • For disk-oriented solutions, Pega Platform servers require read/write access to shared storage .

If custom shared storage implementations are required, the following plug-in for shared storage must be used: com.pega.pegarules.pub.session.CustomPassivationMechanism

Hi Chandrasekar,


Thanks for your reply. If you see my description, i have taken from the pdn articles which states that NFS and disk oriented solutions are not inherently fault tolerant. So it means that we have to go for custom solution. please comment your thoughts
