1 Introduction
P9500 overview
The P9500 is a high capacity, high performance disk array that offers a wide range of storage
and data services, software, logical partitioning, and simplified and unified data replication across
heterogeneous disk arrays. Its large scale, enterprise class virtualization layer combined with
Smart Tiers and Thin Provisioning software, delivers virtualization of internal and external storage
into one pool.
Using this system, you can deploy applications within a new framework, leverage and add value
to current investments, and more closely align IT with business objectives. P9500 disk arrays
provide the foundation for matching application requirements to different classes of storage and
deliver critical services including:
• Business continuity services
• Content management services (search, indexing)
• Non disruptive data migration
• Thin Provisioning
• Smart Tiers
• High availability
• Security services
• I/O load balancing
• Data classification
• File management services
New technological advances improve reliability, serviceability and access to disk drives and other
components when maintenance is needed. Each component contains a set of LEDs that indicate
the operational status of the component.
The system includes new and upgraded software features, including Smart Tiers, and a
significantly improved, task oriented version of Remote Web Console that is designed for ease
of use and includes context sensitive online help. The system documentation has been changed
to a task oriented format that is designed to help you find information quickly and complete tasks
easily.
For host connectivity information, see the P9500 disk array configuration guide.
Hardware overview
The P9500 disk arrays contain significant new technology that was not available in previous disk
arrays. The system can be configured in many ways, starting with a small (one rack) to a large
(six rack) system that includes two controller chassis, up to 2048 HDD drives which include up
to 256 solid state drives, and a total of 1024 GB cache. The system provides a highly granular
upgrade path, allowing the addition of disk drives to the drive chassis, and Processors Blades
and other components to the controller chassis in an existing system as storage needs increase.
The controller chassis (or DKU) of the P9500 disk array can be combined so that what would
previously have been two separate disk arrays are now a single disk array with homogeneous
logic control, cache, and front end and back end interfaces, all mounted in custom HPE 19 inch
racks.
A basic P9500 disk array is a control rack (Rack- 00) that contains a controller chassis and two
drive chassis (factory designation DKU). The fully configured P9500 disk array consists of two
controller chassis and sixteen drive chassis for fully configured system. The controller chassis
contains the control logic, processors, memory, and interfaces to the drive chassis and the host
