An array group also called parity group is the basic unit of storage capacity for the storage system. Device Manager – Storage Navigator program. The basic system architecture of a VSP G, VSP G, and VSP F single controller is includes virtual storage directors microprocessors are shared across the cache, front-end directors host adapters , and back-end directors disk adapters , providing processing power where and when it is needed, without latency or interruption. The following two figures illustrate the RAID 1 configurations. This RAID 5 implementation minimizes the write penalty incurred by standard RAID 5 implementations by keeping write data in cache until the entire stripe can be built, and then writing the entire data stripe to the drives.

See the following user documents for information and instructions about configuring your storage system for Mainframe operations: Mirror disks duplicated writing. Note RAID 5 contains two configurations: Data and parity are striped across each drive in the array group.

The parity chunks and data chunks rotate after each stripe. The Device Manager – Storage Navigator displays detailed storage system information and allows users to configure and perform storage operations on hihachi system.

When your system is configured, the hosts connected to each port are grouped by host y1000 or by target. The data is distributed on the two RAID pairs.

The total data in each stripe is blocks blocks per chunk for Open-systems data. Advantage RAID 1 is highly usable and reliable because of the duplicated data. The tables following the figures describes each configuration. If possible, the primary path and alternate paths should be attached to different channel cards.

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

LDEV striping can be used with all storage system data management functions.

The following two figures illustrate the RAID 1 configurations. To gain these benefits, this storage system supports RAID levels 1, 5 and 6.

Hardware architecture

The storage system supports the following RAID levels: Each of these array groups can be configured as either x or OPEN-x logical devices.

Parity data is generated from data of multiple blocks and written to disk. Host modes and host mode options.

Item Description Description Mirror disks duplicated writing. For complete information about supported operating systems, visit https: The storage system supports the control unit CU emulation type Refer to the following documents for information and instructions hitzchi configuring your storage system for open-systems operations:.

In RAID 6, data can be assured when up to two drives in an array group fail. All drives and device emulation types are supported for LDEV striping. In RAID 1, hitachhi array group is a set of four physical drives where one drive is installed in the same g11000 in each of four contiguous disk trays in the same drive chassis.

The host groups, host modes, and host mode options are configured by using Device Manager – Storage Navigator.

This section provides high-level descriptions of open-systems compatibility, support, and configuration for storage systems. The system provides a highly granular upgrade path, allowing the addition of drives to the drive chassis, and components such as virtual storage directors to the controller chassis as storage needs increase. After a storage system installation is complete, users can configure the storage system for Mainframe operations.

Open-systems compatibility and functionality. Mainframe operating system support. Data is written to multiple disks successively in units of block or blocks.

See the following user documents for information and instructions about configuring your storage system for Mainframe operations:. Users should plan for path failover alternate pathing to ensure the highest data availability.
