Overview of migrating LLT to UDP

Veritas Access uses Low Latency Transport (LLT) for data transfer between applications on nodes. LLT functions as a high-performance, low-latency replacement for the IP stack, and is used for all cluster communications. If your Access cluster includes Direct Attached Storage (DAS) disks, for improved performance, Veritas recommends that you configure LLT over UDP.

This section explains how to migrate a cluster where LLT is already configured over Ethernet to LLT over UDP by utilizing an additional private NIC and an additional network subnet. You must restart the cluster after completing the migration steps.

Note:

At any point of time, if the expectations set in this document don't match those in the cluster, please stop immediately and contact Veritas Technical Support for further assistance.

Limitations

  • The steps described in this document for LLT migration are applicable only for Veritas Access 7.4.2.300 and Veritas Access 7.4.2.301 and should not be used for any other releases.

  • After a cluster is migrated from LLT over Ethernet to LLT over UDP for Access 7.4.2.300 or 7.4.2.301 release, the add node operation on the same release is not expected to work. The cluster must be upgraded to at least version 7.4.2.400 for adding a node to the cluster.

Prerequisites

  • "root" access to log in to the nodes and complete the steps listed in this document.

  • An additional private network subnet, which has the same number of IP addresses as the existing private network subnet.
