Introduction to Disk/Cache Partition

XP Disk/Cache Partition provides logical partitioning of ports, cache, and disk capacity, including external storage to create independently managed and secure private virtual storage machines that help maintain quality of service (QoS).

Large data centers typically support a high volume of users, systems, and applications—each with constantly changing requirements for storage capacity, throughput, priority, security and access, as well as management and control. Traditionally, isolated storage systems could be dedicated to specific applications, but only at the cost of flexibility and ease of management. With decentralized access and control, however, departments can manage their storage systems individually.

HP storage—specifically the XP24000 Disk Array and XP20000 Disk Array (herein after referred to as storage system) – addresses these issues by enabling consolidation, aggregation, and management of large sets of diverse, highly dynamic stored data. By virtualizing storage resources into a single pool, the storage system facilitates flexibility and manageability for IT administrators.

XP Disk/Cache Partition is designed to complement the storage system by allowing IT departments to isolate, segment, and control storage for specific applications, servers, or users. This tool enables data center administrators to perform logical partitioning of ports, cache, and disk capacity, including external storage, on the storage system to create independently managed private virtual storage machines. These logical partitions act as dedicated storage resources that are independently managed and reserved for specific applications.

XP Disk/Cache Partition enables administrators to treat logical partitions as if they were separate storage machines, helping them maintain data security and integrity. The software also allows administrators to grant decentralized access and control of specific partitions to departmental IT managers—a feature that can enhance manageability and free data center administrators to focus on corporate-level projects. By dedicating resources to each partition as needed, administrators also can maintain high QoS for all users. Resources can be allocated based on business requirements and dynamically reconfigured in real time to meet changing needs. Customers can use XP Disk/Cache
