Mainframe Storage

Innovate to improve IBM® mainframe storage performance, reliability and management.

Powerful Mainframe Storage


  • IBM®-tested, compatible mainframe-attached storage
  • All-flash or hybrid configurations improve performance even under the heaviest input/output loads
  • Lower capacity needs, reduce floor space requirements and energy consumption, and make more effective use of limited staff resources
The Hitachi and Turkcell teams have worked closely throughout the project. The collaboration has been key to the success of our new storage environment.
– Bülent Saltürk, Infrastructure and Operations Division Head, Turkcell

Maximize Mainframe Environments


  • Scale-out to add even more performance
  • Fully redundant with non-disruptive upgrades and online microcode updates
  • Replicate data synchronously between systems over metro distances for non-stop operations

Virtualized External Storage Improves Storage Administration

Hitachi Dynamic Provisioning for Mainframe

Automated storage controllers provide storage as necessary, eliminating the need for manual provisioning.

Hitachi Dynamic Tiering for Mainframe

Controllers automatically move consistently accessed data blocks to the highest-tier storage, and less frequently used data to lower tiers.

Hitachi Tiered Storage Manager for Mainframe

Online storage service-level control uses Dynamic Tiering policies to improve performance and avoid potential problems.

Mainframe Storage Software

Hitachi Storage Virtualization Operating System (SVOS)

SVOS offers system management and advanced storage system functions, such as storage virtualization, thin provisioning, storage service-level controls and performance instrumentation across multiple storage platforms. For mainframe storage, SVOS includes Hitachi Device Manager, Hitachi Storage Navigator, Hitachi Dynamic Provisioning for Mainframe, Hitachi Universal Volume Manager, Hitachi Virtual Partition Manager, Hitachi Resource Partition Manager, Hitachi Data Retention Utility, performance monitor feature, volume shredder feature, LUN manager, Hitachi Volume Retention, cache residency manager for mainframe feature, RAIDCOM, Java API, CCI, SMI-S provider and SNMP agent.

Hitachi Compatible PAV for Mainframe Package

Hitachi Compatible PAV for Mainframe package includes Hitachi Compatible PAV for Mainframe and Hitachi Compatible HyperPAV for Mainframe.

Hitachi Compatible PAV for Mainframe

Parallel Access Volume (PAV) support. Compatible PAV for Mainframe is used for achieving fast I/O response time and fast overall system throughput for mainframe environments. It enables the mainframe host system to initiate multiple I/O requests simultaneously to the Hitachi enterprise storage system.

Hitachi Compatible HyperPAV for Mainframe

HyperPAV support. Compatible HyperPAV for Mainframe is used for achieving even faster PAV performance. It extends PAV technology by utilizing I/O virtualization management to achieve higher levels of I/O efficiencies, storage device resource management, and overall system performance throughput.

Hitachi Data Mobility for Mainframe Package

The Hitachi Data Mobility for Mainframe package includes Hitachi Dynamic Tiering for Mainframe and its management tool, Hitachi Tiered Storage Manager for Mainframe.

Hitachi Dynamic Tiering for Mainframe (HDT)

Hitachi Dynamic Tiering for Mainframe simplifies storage administration through automation, automates the complexity of using tiered storage efficiently and delivers top-tier performance to information stored largely on less-expensive tiers. The new active flash mode automatically moves rapidly active data to higher performing tiers in subseconds, delivering extreme workload responsiveness while maximizing flash investments.

Hitachi Tiered Storage Manager for Mainframe (HTSM)

Hitachi Tiered Storage Manager for Mainframe manages Hitachi Dynamic Tiering storage tier definitions and policies. It enables administrators to proactively match business application price, performance and availability characteristics to storage resource attributes.

Hitachi Local Replication Package

Hitachi Local Replication delivers convenient and cost-effective full-volume data cloning for fast, point-in-time data copies within the storage system. Offering includes Hitachi ShadowImage Replication and Hitachi Thin Image snapshot software.

Hitachi Compatible Mirroring for IBM® FlashCopy® (HCMF)

Delivers mainframe (IBM® S/390® and z/OS®) centric data mirroring and ease of use for mainframe and Hitachi enterprise storage environments; provides IBM FlashCopy® compatible command and control of in-system data copy tasks within Hitachi ShadowImage Replication software; Compatible Mirroring for IBM FlashCopy v2 now extends this capability to remote data copies via Hitachi Universal Replicator for 2 data center (2DC) or 3 data center (3DC) configurations.

Hitachi Compatible Software for IBM® FlashCopy® SE (HCFCSE)

Provides an in-system solution for data protection that is IBM mainframe compatible. It combines snapshots and virtual data management to create logical point-in-time (PiT) copies. Once a FlashCopy SE source-target volume relationship is established, HCFCSE enables thin-provisioned storage capacity that is allocated and utilized only when a change has occurred within the source volume. As backup copies are made to the target volume, storage resources are consumed only on an as-needed basis, depending on the amount of changed data.

Hitachi Remote Replication Package

Package includes Hitachi TrueCopy for Mainframe, Hitachi Universal Replicator for Mainframe and Hitachi Business Continuity Manager software.

Hitachi TrueCopy for Mainframe

Enables synchronous remote replication of mission-critical data from a primary data center to a second data center up to 300km away. Hitachi TrueCopy for Mainframe delivers immediate, zero recovery point objective (RPO), and automated failover capabilities.

Hitachi Universal Replicator for Mainframe

Features journal disk caching for achieving tight RPO time capabilities, even in the event of a network outage. Universal Replicator for Mainframe provides asynchronous remote copy, over any distance, for Hitachi enterprise storage.

Hitachi Business Continuity Manager (BCM)

Provides a central management utility for automating Hitachi ShadowImage Replication, Hitachi TrueCopy (synchronous), and Hitachi Universal Replicator operations for mainframe (IBM® S/390®, z/OS®) environments. BCM is a requisite for Universal Replicator implementations.

Hitachi Remote Replication Extended Package

Package includes Hitachi TrueCopy Extended Distance and Hitachi Business Continuity Manager Extended to enhance Hitachi Remote Replication for Mainframe, adding advanced 3DC capabilities such as delta-resync.

Hitachi TrueCopy Extended Distance

Leverages asynchronous remote replication to extend the volume cloning capabilities of TrueCopy over any distance.

Hitachi Business Continuity Manager (BCM) Extended

Extends BCM to include extended distance management capability. It requires Universal Replicator 4x4 extended consistency group when implementing a 4x4 Universal Replicator configuration.

Hitachi Compatible Replication for IBM® XRC® (HCRX)
