Doubling the capacity density\nAs data center professionals across the globe work to meet growing enterprise needs, they\nface the dilemma of storing more data in the same footprint while also reducing power and HVAC\nconsumption. The new Ultrastar A7K2000 provides twice the data storage capacity of the\nprior generation Ultrastar A7K1000 drive, and does so using fewer watts. It is now possible to\nachieve a colossal 1.2 petabytes (PB) in the footprint of a standard 19-inch enterprise storage\nrack by deploying the 2TB A7K2000 in a stack of ten 4U, 60-bay enclosures.\n\nCombining 7200 RPM performance and granular power control\nOperating at 7200 RPM, the Hitachi Ultrastar A7K2000 offers better overall performance than\nslower-RPM, capacity-oriented drives at impressively low power-consumption rates. When\ncompared to the previous generation Ultrastar A7K1000, the A7K2000 offers up to a 155%\nimprovement in sustained data transfer rate, and a 120% improvement in watts-per-GB. With\nfive Advanced Power Management modes, a 36% reduction in watts during low-RPM idle\nmode, and using less than 1W during standby/sleep mode, the Ultrastar A7K2000 can help\ndata centers achieve lower AC power and HVAC requirements, freeing up precious headroom\nfor growing enterprise needs.\n\nEnhancing data safety and security\nTo ensure the utmost in data safety and security, the Ultrastar A7K2000 is also available with\na bulk data encryption (BDE) option. When enabled, the Hitachi BDE implementation encrypts\nall data on the drive using a private security key as it is written to the disk, and then decrypts\nit with the key as it is retrieved, giving users an extreme level of data protection. Unlike softwarebased\nencryption solutions, the Hitachi BDE implementation is hardware-based, so it doesn’t\nslow the system down. This technology also speeds up and simplifies the drive re-deployment\nand decommissioning process. By deleting the encryption key, the data is rendered unreadable,\nthereby eliminating the need for time-consuming, multi-pattern data overwrite.\n\nDelivering industry-leading reliability\nWith a robust fourth-generation mechanical design, Ultrastar A7K2000 is specifically built and\ntested for the enterprise. The Ultrastar SATA drive family features Hitachi-patented Rotational\nVibration Safeguard (RVS) sensor technology, which optimizes drive reliability in multi-drive\nRAID arrays and rack-mounted systems. Backed by a five-year warranty, the Ultrastar platform\nhas earned Hitachi a reputation among server and storage vendors as a global partner\ndedicated to delivering the highest quality and reliability in the industry.\n\nInnovation for a more sustainable environment\nThe Ultrastar A7K2000 demonstrates Hitachi ecological leadership with its halogen-free\ndesign and power-efficient operation. Both these features serve to qualify the drive for the\nHitachi EcoTrac classification, which identifies products that minimize environmental impact\nin the areas of product design, manufacturing, operation and disposal.\n\nHitachi quality and service\nHitachi’s Ultrastar A7K2000 extends the company’s long-standing tradition of performance and capacity leadership. The proven drive design enables high reliability and availability to customer data. Ultrastar quality, performance, and world class technical support and service provides customers with a lower total cost of ownership over previous generations. Hitachi drives are backed by an array of technical support and services, which may include customer and integration assistance. Hitachi is dedicated to providing a breadth of hard disk drive solutions to satisfy all of today’s demanding computing needs.
