The Solution: Simplified Data Security and Storage Across Multiple Sites
Hitachi Vantara has supported the Free State of Bavaria by optimizing its data storage and management since 2007. A particular challenge was a major data center migration in 2012, when the IT infrastructure was relocated from Munich city center to a new site in the east of the state’s capital. From 2015 onwards, further consolidation of the state's data centers was on the agenda. The state government's requirement was to unify all IT operations, with the exception of tax administration, justice and police, with IT-DLZ.
To meet the state’s digital objectives, IT-DLZ decided to supplement its existing storage infrastructure consisting of block, file and tape storage with object storage. This represented a good choice both in terms of performance and costs. The implementation of Hitachi Content Platform (HCP) and Hitachi Data Ingestor (HDI) also enabled IT-DLZ to move closer to the goal of automatically separating "hot" and "cold" data.
Following extensive collaboration between Hitachi Vantara and IT-DLZ, a proof of concept was conducted to evaluate the suitability of the new platform. Extensive tests were carried out on the functionality and performance of the system alongside the existing data center infrastructure.
Hitachi Vantara also held several workshops to provide the IT-DLZ team with the necessary knowledge and to explain the platform's capabilities to application developers and other interested parties within the government administration. "Hitachi Vantara was involved in every phase of the implementation. The workshops enabled our customers to clarify specific questions," says Stangl.
IT-DLZ deployed two HCP solutions that provide object-based storage for unstructured and large amounts of data, as well as a third instance for recovery after a failure. "Hitachi Vantara's object-based storage approach gives us the scalability and security we need. At the same time, it reduces costs per gigabyte and space requirements in the data center," explains Stangl.
Thanks to the Amazon S3 and OpenStack SWIFT interfaces, IT-DLZ and state authorities can develop strategies and solutions that directly exploit the advantages of object storage, such as extensive application-specific metadata.
Several Free State of Bavaria government sites now have virtual or physical HDI installations with file server functionality. These provide remote users with local cached storage for active data. At the same time, all data is replicated to the central HCP infrastructure, keeping capacity low at remote sites and protecting data in an optimum way.
For large amounts of information, it is essential to have short backup times and the ability to restore files quickly and easily when needed. Government data is protected by versioned and overwrite-proof storage at several locations.
The multi-tenant Hitachi Vantara solution also simplifies compliance when storing administrative data, for example by defining expiration dates or retention periods. Digital signatures ensure the data integrity of each object.
