About Storage Foundation Cluster File System High Availability
Storage Foundation Cluster File System High Availability (SFCFSHA) is a storage management solution to enable robust, manageable, and scalable storage deployment. SFCFSHA maximizes your storage efficiency, availability, agility, and performance across heterogeneous server and storage platforms. SFCFSHA extends Storage Foundation to support shared data in a storage area network (SAN) environment. Using SFCFSHA, multiple servers can concurrently access shared storage and files transparently to applications. SFCFSHA also provides increased automation and intelligent management of availability and performance.
Storage Foundation Cluster File System High Availability consists of product components and features that can be used individually and together to improve performance, resilience and ease of management for your storage and applications.
Table: Storage Foundation Cluster File System High Availability components describes the components of Storage Foundation Cluster File System High Availability.
Table: Storage Foundation Cluster File System High Availability components
Component | Description |
---|---|
Dynamic Multi-Pathing (DMP) | Manages the I/O performance and path availability of the physical storage devices that are configured on the system. DMP creates DMP metadevices across all of the paths to each LUN. DMP uses the DMP metadevices to manage path failover and I/O load balancing across the paths to the physical devices. DMP metadevices provide the foundation for Veritas Volume Manager (VxVM) and Veritas File System (VxFS). DMP also supports native operating system volumes and file systems on DMP devices. |
Veritas Volume Manager (VxVM) | Provides a logical storage abstraction layer or storage management between your operating system devices and your applications. VxVM enables you to create logical devices called volumes on the physical disks and LUNs.The applications such as file systems or databases access the volumes as if the volumes were physical devices but without the physical limitations. VxVM features enable you to configure, share, manage, and optimize storage I/O performance online without interrupting data availability. Additional VxVM features enhance fault tolerance and fast recovery from disk failure or storage array failure. |
Cluster Volume Manager (CVM) | Extends the VxVM logical volume layer for use with multiple systems in a cluster. Each system, or cluster node, can share access to the same logical devices or volumes. Each node sees the same logical storage in the same state. CVM supports VxVM features that improve performance, such as striping, mirroring, and creating snapshots. You manage the shared storage using the standard VxVM commands from one node in the cluster. All other nodes immediately recognize any changes in disk group and volume configuration with no user interaction. |
Veritas File System (VxFS) | Provides a high-performance journaling file system. VxFS is designed for use in operating environments that deal with large amounts of data and that require high performance and continuous availability. VxFS features provide quick-recovery for applications, scalable performance, continuous availability, increased I/O throughput, and increased structural integrity. |
Cluster File System (CFS) | Extends the VxFS file system for use with multiple systems (or nodes) in a cluster. CFS enables you to simultaneously mount the same file system on multiple nodes. CFS features simplify management, improve performance, and enable fast failover of applications and databases. |
Cluster Server (VCS) | Provides high availability functionality. VCS provides monitoring and notification for failures of the cluster nodes. VCS controls the startup and shutdown of component layers and facilitates failover of services to another node. |
Volume Replicator (VVR) | Enables you to maintain a consistent copy of application data at one or more remote locations for disaster recovery. VVR replicates data to remote locations over any standard IP network to provide continuous data availability. VVR can replicate existing VxVM configurations, and can be transparently configured while the application is active. VVR option is a separately-licensable feature of Storage Foundation Cluster File System High Availability. |
I/O fencing | Protects the data on shared disks when nodes in a cluster detect a change in the network cluster membership with a potential split brain condition. |
