The overview describes the architecture of the storage system. Refer to the following documents for information and instructions about configuring your storage system for open-systems operations:. Data and parity are striped across each drive in the array group. The data is distributed on the two RAID pairs. Your download will begin in a moment.

Data blocks are scattered to multiple disks in the same way as RAID 5 and two parity disks, P and Q, are set in each row. The total data in each stripe is blocks g11000 per chunk for Open-systems data.

The number of connected hosts is limited only by the number of Fibre Channel ports installed and the requirement for alternate pathing within each host. If the workload of one array group is higher than another array group, you can distribute the workload by combining the array groups, thereby reducing the total workload concentrated on each specific array group.

The mainframe data management hitachu of the storage system can restrict CU image compatibility. In RAID 6, data can be assured when up to two drives in an array group fail.

Hardware architecture

Data and parity are striped hifachi each drive in the array group. Each chunk contains logical blocks. The Provisioning Guide for Mainframe Systems provide instructions for converting single volumes LVIs into multiple smaller volumes hitqchi improve data access performance. This configuration is highly usable and reliable because of the duplicated data.


The host attachment guide provides information and instructions to configure the storage system and data storage devices for attachment to the open-systems hosts.

All drives and device emulation types are supported for LDEV striping.

Dynamic tiering within a single standalone system or across an entire heterogeneous storage pool and intelligent file tiering combined with automated migration.

This RAID 5 implementation minimizes the write penalty incurred by standard RAID 5 implementations by keeping b1000 data in cache until the entire stripe can be built, and then writing the entire data stripe to the drives. Storage ControllersStorage Solutions.

Performance of the random writing is lower than RAID hirachi when the number of drives makes hktachi bottleneck. The advantages of LDEV striping are: The System Administrator Guide provides instructions for installing, configuring, and using Device Manager – Storage Navigator to perform resource and data management operations on the storage systems.

The parity chunks and data chunks rotate after each stripe. An array group also called parity group is the basic unit of storage capacity for the storage system.

Support of pools with capacity of up to It can be installed on a PC, laptop, or workstation. The Mainframe Host Attachment and Operations Guidedescribes and provides instructions related to configuring the storage system for Mainframe operations, including FICON attachment, hardware definition, cache operations, and device operations.


Open-systems host platform support. Features External SAN storage virtualization capability Fully redundant architecture with no single point of failure and support for online hardware upgrades, hot preventive maintenance, and pro-active drive sparing.

Item Description Description Mirror disks duplicated writes. The host modes and host mode options enhance compatibility with supported platforms and environments. In addition to full System Managed Storage SMS compatibility, the storage system provides the following functions and support in a Mainframe environment:.

Each Fibre Channel port on the storage system provides addressing capabilities for up to 2, LUNs across as many as host groups, each with its own LUN 0, host mode, and host mode options. Mirror disks duplicated writes.

The storage system supports the control unit CU emulation type Note The storage system queue depth and other parameters are adjustable. You should receive the requested information within a week. Requires disk capacity twice as large as the user data.
