HP X9000 Software features
HP X9000 Software is a scale-out, network-attached storage solution composed of a parallel file
system for clusters, an integrated volume manager, high-availability features such as automatic failover
of multiple components, and a centralized management interface. X9000 Software can be deployed
in environments scaling to thousands of nodes.
Based on a Segmented File System architecture, X9000 Software enables enterprises to integrate I/O
and storage systems into a single clustered environment that can be shared across multiple applications
and managed from a single central management console.
X9000 Software is designed to operate with high-performance computing applications that require
high I/O bandwidth, high IOPS throughput, and scalable configurations. Examples of these applications
include Internet streaming, rich media streaming, data mining, web search, manufacturing, financial
modeling, life sciences modeling, and seismic processing.
Some of the key features and benefits are as follows:
• Scalable configuration. You can add servers to scale performance and add storage devices to
scale capacity.
• Single namespace. All directories and files are contained in the same namespace.
• Multiple environments. Operates in both the SAN and DAS environments.
• High availability. The high-availability software protects servers.
• Tuning capability. The system can be tuned for large or small-block I/O.
• Flexible configuration. Segments can be migrated dynamically for rebalancing and data tiering.
High availability and redundancy
The segmented architecture is the basis for fault resilience—loss of access to one or more segments
does not render the entire file system inaccessible. Individual segments can be taken offline temporarily
for maintenance operations and then returned to the file system.
To ensure continuous data access, X9000 Software provides manual and automated failover protection
at various points:
• Server. A failed node is powered down and a designated standby server assumes all of its segment
management duties.
• Segment. Ownership of each segment on a failed node is transferred to a designated standby
server.
• Network interface. The IP address of a failed network interface is transferred to a standby network
interface until the original network interface is operational again.
