The document summarizes Veritas Cluster File System (CFS) with Remote Direct Memory Access (RDMA). CFS provides a scalable, shared file system across cluster nodes. RDMA capabilities from InfiniBand Architecture can improve CFS performance by reducing CPU usage and latency through zero-copy data transfers and remote direct memory access. Key CFS components like the Group Lock Manager benefit from RDMA to enhance coherency and recovery. The Common RDMA Transport Access Layer abstracts RDMA calls to enable CFS to support different transports.

Talk about each component. Indicate that SAN is a must. Only Symmetrix is available direct attached.
CVM allow for failover without migration, simultaneous access you expect and common naming Simultaneous access to volumes from multiple hosts Common logical device name Consistent logical view of volumes from any host Managed from any host in the cluster - updates seen by all nodes Only raw device access supported from CVM Volumes remain accessible from other hosts after a single host failure Failover does not require volume migration
Good Morning, It’s a little hard to follow that whimsical view of business - but I hope it gave you a view of the issues most of you face in your business today. What I like to do now is take you a little deeper into how VERITAS can offer you a strategy for increasing availability of your business information.
