Storage Foundation and High Availability Solutions 5.x and 6.0 for Windows Configuration Checker detects a VMWare environment for compatibility
Overall compatibility guidance for all products in the Veritas Storage Foundation and High Availability (HA) Solutions for Windows suite:
The following base products, Storage Foundation for Windows, Storage Foundation HA/Disaster Recovery (DR) for Windows, Veritas Cluster Server for Windows and their associated options such as Veritas Dynamic Multi-pathing, FlashSnap, Microsoft Cluster option, and Veritas Volume Replicator are ALL supported in guest ONLY.
For versions of VMware supported, please reference the Veritas Storage Foundation and HA Solutions Software Compatibility Lists available on the Symantec Support Website.
Specific compatibility guidance or caveats for product components in the Storage Foundation and HA Solutions for Windows suite:
Storage Foundation for Windows
Certain features within the Volume Manager in Storage Foundation for Windows rely upon direct interaction and knowledge of the underlying storage array. These features, which can be optionally used or not used, include items such as Track Aligned Volumes or Thin Provisioning Awareness and Reclamation. If you would like to take advantage of these features that rely upon knowledge of the specific type of storage array, you must utilize VMware RDM storage presented to the guest versus the use of vmdk storage devices to the guest.
Dynamic Multi-pathing (DMP) Option
DMP is only supported in a VMware guest environment when iSCSI storage is directly presented to the guest. The guest has no underlying knowledge of the SAN based hardware or storage as seen by the hypervisor. iSCSI presentation to the guest allows for direct interaction and management of storage at the guest level; therefore, multi-pathing can also be directly managed by the Microsoft MPIO framework and DMP.
Veritas Volume Replicator (VVR) Option
VVR is fully supported when replicating guest to guest. In an asynchronous or synchronous-override replication mode, a Storage Replicator Log (SRL) will be utilized to track and maintain write-order fidelity. Tracking changes does lead to additional I/O. Best practice suggests that you both consider separate devices for your SRL as well as to measure I/O performance and throughput in order proactively avoid I/O performance problems within your VMware environment.
Storage Foundation HA for Windows or Veritas Cluster Server for Windows
Shared storage for a protected clustered instance of an application, must be presented to all guests that are failover targets for that application via VMware RDM versus the use of vmdk.
