Hitachi HUS157373EL3600, HUS157373EL3800, HUS157336EL3600 Description, Characteristics, K6602906 10/46 2003/6/12

HUS157373EL3800, HUS157373EL3600, HUS157336EL3600, HUS157336EL3800 specifications

The Hitachi HUS157336EL3600 and HUS157373EL3600, along with the HUS157336EL3800 and HUS157373EL3800, are part of the Hitachi Virtual Storage Platform (VSP) E-series, designed to address the demanding needs of enterprise environments. These high-capacity storage systems are tailored for data-intensive applications, ensuring reliability, performance, and scalability.

A standout feature of the HUS157336EL and HUS157373EL series is their exceptional storage capacity, with the former offering up to 36TB and the latter providing up to 73TB of available storage. This substantial capacity makes them ideal for organizations storing vast amounts of unstructured data, including multimedia files, large databases, and backup solutions.

Both models leverage advanced data protection technologies. Hitachi’s Data Protection Manager (DPM) technology provides robust backup and recovery solutions, enabling businesses to safeguard their critical information effortlessly. Additionally, features like snapshots and replication guarantee data integrity and accessibility, even in the event of hardware failure or accidental deletions.

Performance is another critical aspect. These systems utilize Hitachi’s proprietary Flash of Flash (FoF) technology, which significantly enhances input/output operations per second (IOPS) while minimizing latency. This is particularly beneficial for mission-critical applications that require rapid data retrieval and processing.

Moreover, the HUS157336EL and HUS157373EL series support automated tiering and storage optimization. This allows organizations to manage their storage resources efficiently, moving less frequently accessed data to lower-cost storage media without any disruption to daily operations. This feature not only helps manage costs but also enhances the overall performance of the system.

Both the HUS157336EL3600 and HUS157373EL3600 are built with energy efficiency in mind, featuring power-saving technologies that reduce energy consumption while maintaining top-notch performance. This focus on sustainability aligns with the growing need for organizations to operate environmentally responsibly.

In summary, the Hitachi HUS157336EL3600, HUS157373EL3600, HUS157336EL3800, and HUS157373EL3800 exemplify cutting-edge storage solutions that cater to the needs of modern enterprises. With high capacity, advanced data protection, exceptional performance, automated tiering, and energy efficiency, these systems represent a significant investment in securing and managing critical data assets for businesses across various industries.
