This guide provides the volume operation theories and specifications for the essential data reduction and volume management capabilities of the Storage Virtualization Operating System RF 9 (SVOS RF 9), including Dynamic Provisioning, Dynamic Tiering, LUN Manager, Universal Volume Manager (external storage).

Managing volumes includes tasks such as configuring hosts and ports, creating volumes and pools, mapping external volumes, configuring LU paths, managing tiered storage, and applying deduplication and compression to reduce the storage capacity used by your data.

Provisioning

Provisioning is a method or strategy of managing the logical devices (LDEVs), also called volumes, on a storage system. Some provisioning methods are host-based, while other methods use inherent storage system capabilities such as concatenated parity groups. Provisioning methods can also be primarily hardware-based or software-based. Each method has its particular uses and benefits in a specific storage environment, such as optimizing capacity, reliability, performance, or cost. When used in the right scenario, each method can be cost-effective, efficient, reliable, and straightforward to configure and maintain. Your support representatives are available to help you configure the highest quality solution for your storage environment.
Host Attachment

The Hitachi RAID storage systems provide heterogeneous connectivity to support multiple concurrent attachment to a variety of host operating systems, including UNIX, Windows, VMware, Linux, and mainframe servers, enabling massive consolidation and storage aggregation across disparate platforms. The storage systems can operate with multi-host applications and host clusters, and are designed to handle very large databases as well as data warehousing and data mining applications that store and retrieve terabytes of data. The storage systems are compatible with most Fibre Channel host bus adapters (HBAs), iSCSI adapters, and FC-over-ethernet (FCoE) converged network adapters (CNAs).
Tiered Storage

Hitachi Dynamic Tiering (HDT) simplifies storage administration by automatically optimizing placement of data in up to 3 tiers of storage that can be defined and used within a single virtual volume. The storage tiers can be made up of internal or external (virtualized) storage. Simplified and unified management of HDT allows for lower operational costs and reduces the challenges of ensuring applications are placed on the appropriate classes of storage.
Data Reduction

Hitachi Storage Virtualization Operating System (SVOS) software delivers superior adaptive data reduction (ADR) and operational efficiency, covering a broad range of efficiency services including thin provisioning, snapshots and linked clones, compression, deduplication, and cloud connect. SVOS RF 9 adaptive data reduction intelligence is optimized for the highest system throughput and response time consistency. In addition, SVOS manages the ADR services used based on configuration. For example, when flash module drives (FMDs) are detected, drive-based compression is used.
External Storage
No image available
The Hitachi Universal Volume Manager (UVM) feature enables you to connect volumes in external heterogeneous storage systems to your Hitachi RAID storage system and manage and manipulate the data in your mapped volumes using Hitachi Storage Virtualization Operating System (SVOS) RF 9 software products and functionality. Use of Hitachi Dynamic Provisioning and Hitachi Dynamic Tiering along with virtualization of both internal and external storage provides the best application performance and automated management of your storage tiers.
