Seagate releases first dual magnetic arm hard drive Galaxy 2X14: Double performance

Seagate today announced the launch of the Galaxy Exos 2X14 Enterprise Drive, with a capacity of 14TB, the world’s first drive integrating Seagate MACH.2 multi-magnetic arm technology. Several customers are already testing it and will be deployed in the data center on a large scale in the future. MACH.2 has two magnetic arms in a traditional mechanical hard drive that can work independently on the same hard drive, and the IO operation is parallel.

Among them, the upper part of the read and write head is driven by a magnetic arm, while the lower half is dominated by another magnetic arm, each magnetic arm is responsible for half of the total capacity of the hard disk, so a hard disk, double IOPS, solve the challenge of IOPS/TB (random performance per unit capacity).

Seagate says it has demonstrated its advantages over single magnetic arm in many applications, including content distribution networks (CDNs), video streaming, mail servers, backup/transmission services, Hadoop, cloud applications, and more.

Microsoft has completed the first phase of functional deployment testing of Seagate Galaxy Exos 2X14 hard drives, including complete infrastructure testing to verify interoperability and compatibility with data center infrastructure, product durability, reliability, and Microsoft Olympus program (next-generation ultra-large-scale cloud computing hardware model) The integration of the system architecture, as well as performance testing, including sequential throughput testing (simulated backup operations or streaming), random read IOPS testing (simulating large-scale and CDN workloads), and more.

Microsoft has high expectations for MACH.2 dual magnetic arm technology, hoping to maintain the IOPS input and output random read and write performance required for Microsoft cloud services such as Azure and Exchange, increasing the available storage capacity in the data center, and with the successful completion of early testing. MACH.2 achieved expectations at high IOPS workloads, with throughput and IOPS performance nearly twice that of traditional single-magnetic arm drives.

In fact, Microsoft has been a close partner of Seagate throughout the development and launch of MACH.2 multi-magnetic arm technology.

Seagate also stressed that MACH.2 will eliminate the “shelving capacity” problem , where all of the hard drive’s capacity cannot be fully utilized under the target workload if the IOPS/TB of the mechanical hard drive is below the value set by the workload.

For example, in order to maintain the expected quality of service, a 16TB hard drive requires twice the throughput of an 8TB hard drive, but when the application exceeds the maximum IOPS of the storage device, the only solution is to store less data, resulting in capacity shelving, a “stopgap” is to store performance-requiring data in the outside of the hard disk, Secondary data storage is stored in the inner ring, which avoids only two-thirds of the hard disk capacity, but can complicate data management.

Now with MACH.2 technology, data centers can have a 14TB dual arm drive for each slot, very similar to the high throughput of two 7TB drives, and can take full advantage of all capacity.
