Global storage virtualization enables an always-on infrastructure. When your system is configured, the hosts connected to each port are grouped by host group or by target. The tables following the figures describe each configuration. Flexible Placement in Data Center: Mirror disks duplicated writing.

Storage ControllersStorage Solutions. All drives and device emulation types are supported for LDEV striping.
For more information about supported operating systems, see the mainframe support matrix on https: LDEV striping can be used with hitahci storage system data management functions. The data is written across the eight drives in a stripe that has six data chunks and two htiachi chunks.
The Provisioning Guide for Mainframe Systems provide instructions for converting single volumes LVIs into multiple smaller volumes to improve data access performance. In RAID 1, an array group is a set of four physical drives where one drive is installed in the same location in each of four contiguous disk trays in the same drive chassis.

The number of connected hosts is limited only by the number of Fibre Channel ports installed and the requirement for alternate hjtachi within each host. In addition to full System Managed Storage SMS compatibility, the storage system provides the following functions and support in a Mainframe environment:.
The advantages of LDEV striping are:.
You should receive the requested information within a week. The advantages of LDEV striping are: RAID 1 is highly usable and reliable because of the duplicated data. Note RAID 5 jitachi two 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.
Flexible Placement in Data Center: The tables following the figures describe each configuration. Integrated active mirroring enables volume extensibility between systems and across sites through the provisioning and management of active-active volumes up to km apart.
After a storage system installation is complete, users can configure the storage system for Mainframe operations. The SVP obtains storage system configuration and status information and sends user-initiated commands to the storage system. Refer to the following documents for information and instructions about configuring your storage system for open-systems operations: For complete information about supported operating systems, visit https: Note RAID 6 contains two configurations: The RAID 2 is shown by the red rectangles.

The storage system supports the following RAID levels: The system provides a highly granular upgrade path, allowing hitcahi addition of drives to the drive chassis, and components such as virtual storage directors to the controller chassis as storage needs increase. It can provide high reliability and usability at a comparatively low cost by virtue of the parity data.
See the following figure. Device Manager – Storage Navigator program. Therefore, data can be assured even when failures occur in up to two disk hitachj in a parity group.
Parity data is generated from data of multiple blocks and written to disk. Open-systems compatibility and functionality. To gain these benefits, this storage system supports RAID levels 1, 5 and 6.
The data is written across the four drives or eight drives in a stripe that has three or seven data chunks and one parity chunk. The supported LDEV striping configurations are: The following figure illustrates the RAID 6 configuration and the table describes the configuration.
