For the VxVM and VxFS features in Veritas InfoScale Foundation, Veritas InfoScale Storage and Veritas InfoScale Enterprise products, SmartIO supports the use of SSD devices exported by FSS to provide caching services for applications running on VxVM volumes and VxFS file system. In this scenario, Flexible Storage Sharing (FSS) exports SSDs from nodes that have a local SSD. FSS then creates a pool of the exported SSDs in the cluster. From this shared pool, a cache area is created for those nodes in the cluster that do not have local SSDs. Each cache area is accessible only to that particular node for which it is created. The cache area can be a VxVM cache area or a VxFS cache area. The cache areas can be enabled to support warm or persistent caching across reboots.
