2 Introduction HP Scalable NAS provides a cluster structure for managing a group of network servers and a Storage Area Network (SAN) as a single entity. It includes a cluster filesystem for accessing shared data stored on a SAN and provides failover capabilities for applications. The Cluster Volume Manager can be used to create and manage dynamic volumes, which allow large filesystems to span multiple disks, LUNs, or storage arrays. FS Option provides scalability and high availability for the Network File System (NFS). NFS is commonly used on UNIX and Linux systems to share files remotely. MxDB-Oracle-HiAv provides high availability for Oracle database instances and Net Services listener processes. It is intended for Oracle single-instance databases (non-RAC). Database administrators should refer to the MxDB-Oracle-HiAv administration guide and the MxDB-Oracle-HiAv release notes for information about using this software. Product features HP Scalable NAS provides the following features: • Fully distributed data-sharing environment. The PSFS filesystem enables all servers in the cluster to directly access shared data stored on a SAN. After a PSFS filesystem has been created on a SAN disk, all servers in the cluster can mount the filesystem and subsequently perform concurrent read and/or write operations to that filesystem. PSFS is a journaling filesystem and provides online crash recovery. • Availability and reliability. Servers and SAN components (Fibre Channel switches and RAID subsystems) can be added to a cluster with minimal impact, as long as the operation is supported by the underlying operating system. HP Scalable NAS includes failover mechanisms that enable the cluster to continue operations without interruption when various types of failures occur. If network communications fail between any or all servers in the cluster, HP Scalable NAS maintains the coherency and integrity of all shared data in the cluster.
