NEW – Hitachi Dynamic Provisioning

Hitachi Dynamic Provisioning is a new and advanced thin-provisioning software product for the Universal Storage Platform V/VM that provides “virtual storage capacity” to simplify administration and addition of storage, eliminate application service interruptions, and reduce costs.

Dynamic Provisioning allows storage to be allocated to an application without being physically mapped until it is used. This “just-in-time” provisioning decouples the provisioning of storage to an application from the physical addition of storage capacity to the storage system to achieve overall higher rates of storage utilization. Dynamic Provisioning also transparently spreads many individual I/O workloads across multiple physical disks. This I/O workload balancing feature directly reduces performance and capacity management expenses by eliminating I/O bottlenecks across multiple applications.

Enables the user to perform remote copy operations between storage systems in different locations. TrueCopy provides synchronous and asynchronous copy modes for open-system and mainframe data.

Allows the user to create internal copies of volumes for purposes such as application testing and offline backup. Can be used in conjunction with TrueCopy to maintain multiple copies of data at primary and secondary sites.

Provides compatibility with th e IBM FlashCopy mainframe host software function, which performs server-based data replication for mainframe data.

Provides a RAID storage-based hardware solution for disaster recovery which enables fast and accurate system recovery, particularly for large amounts of data which span multiple volumes. Using UR, you can configure and manage highly reliable data replication systems using journal volumes to reduce chances of suspension of copy operations.

Provides compatibility with the IBM Extended Remote Copy (XRC) mainframe host software function, which performs server-based asynchronous remote copy operations for mainframe LVIs.

Provides ShadowImage functionality using less capacity of the storage system and less time for processing than ShadowImage by using “virtual” secondary volumes. COW Snapshot is useful for copying and managing data in a short time with reduced cost. ShadowImage provides higher data integrity.

Realizes the virtualization of the storage system. Users can connect other storage systems to the USP V/VM and access the data on the external storage system over virtual devices on the USP V/VM. Functions such as TrueCopy and Cache Residency can be performed on the external data.

Provides storage logical partition and cache logical partition:

 Storage logical partition allows you to divide the availab le storage

among various users to reduce conflicts over usage.

 Cache logical partition allows you to divide the cache into multiple

virtual cache memories to reduce I/O contention.

Allows users to employ SSL-encrypted communications with the Hitachi Universal Storage Platfo r m V/VM.

Allows open-system users to concatenate multiple LUs into single LUs to enable open-system hosts to acc ess the data on the entire Universal Storage Platform V/VM using fewer logical units.

Enables users to convert single volumes (LVIs or LUs ) into multiple smaller volumes to improve data access performance.

Allows users to “lock” and “unlock” data into cache in real time to optimize access to your most frequently accessed data.

Enables the mainframe host to issue multiple I/O requests in parallel to single LDEVs in the USP V/VM. Compatible PAV provides compatibility with the IBM Workload Manager (WLM) host software function and supports both static and dynamic PAV functionality.

Allows users to restrict host access to data on the USP V/VM. Opensystem users can restrict host access to LUs based on the host’s world wide name (WWN). Mainframe users can restrict host access to LVIs based on node IDs and logical partition (LPAR) number s.

Prevents corrupted data environments by identifying and rejecting corrupted data blocks before they are written onto the storage disk, thus minimizing risk and potential costs in backup, restore, and recovery operations.

Allows users to protect data from I/O operations performed by hosts. Users can assign an access attribute to each logi cal volume to restrict read and/or write operations, preventing unauthorized access to data.

Allows open-system users to designate prioritized ports (for example, for production servers) and non-prioritized ports (for example, for development servers) and set thresholds and upper limits for the I/O activity of these ports.

Enables open-system users to perform data replication and data protection operations by issuing commands from the host to the Hitachi storage systems. The CCI software supports scripting and provides failover and mutual hot standby functionality in cooperation with host failover products.

Enables users to transfer data between mainframe and open-system platforms using the FICON and/or ESCON channels, for high-speed data transfer without requiring network communication links or tape.

Provides simple, integrated, single-point, multipath storage connection management and reporting. Improves system reliability and reduces downtime by automated path health checks, reporting alerts and error information from hosts, and assisting with rapid troubleshooting. Administrators can optimize application performance by controlling path bandwidth (per host LUN load balancing), and keep applications online while performing tasks that require taking a path down by easily switching to and from alternate paths

Provides automatic load balancing, path failover, and recovery capabilities in the event of a path failure.

Enables users to manage the Hitachi storage systems and perform functions (e.g., LUN Manager, ShadowImage) from virtually any location via the Device Manager Web Client, command line interface (CLI), and/or third-party application.

Designed to handle a variety of storage systems to simplify storage management operations and reduce costs. Works together with HiCommand Device Manager to provide the functionality to integrate, manipulate, and manage storage using provisioning plans.

Enables mainframe users to make Po int-in-Time (PiT) copies of production data, without quiescing the application or causing any disruption to end-user operations, for such uses as application testing, business intelligence, and disaster recovery for business continuance.

Supports management of storage replication (copy pair) operations, enabling users to view (report) the configuration, change the status, and troubleshoot copy pair issues. Replication Monitor is particularly effective in environments that include multiple storage systems or multiple physical locations, and in environments in which various types of volume replication functionality (such as both ShadowImage and TrueCopy) are used.
