Huawei is growing a mysterious new “magneto-electric” storage know-how


Bottom line: Huawei was severely impacted by US sanctions towards know-how exports to China, however the firm is way from completed. Its engineers are apparently engaged on a brand new sort of storage know-how, an progressive medium that would theoretically provide important enhancements over conventional tape or onerous disk-based units.

Huawei, unable to obtain the most recent onerous disk know-how for its storage wants as a result of sanctions, has opted to develop its personal archival-grade media tech. The Chinese firm is engaged on “magneto-electrical disks” (MED) for its OceanStor Arctic rack-based storage answer set to debut by 2025.

According to Huawei, the brand new MED know-how guarantees important, maybe unprecedented, enhancements over conventional archival storage media, onerous disks, or tapes. Described as dependable, environment friendly, and cost-effective, MED media function in a “robot-free” setting and are extremely adaptable, that includes sealed disks appropriate for normal information facilities.

The MED know-how seems to mix components of magnetic tape and flash reminiscence chips, providing learn and write capabilities inside every “disk.” However, Huawei has but to disclose detailed workings of the know-how. The firm has solely talked about that MED disks devour 71W of energy per petabyte, offering a formidable 90 % vitality saving in comparison with magnetic onerous disk drives (HDDs).

Expected MED efficiency is 8GB/s per rack, in response to Huawei, marking a 2.5x enhance over the utmost efficiency of archival tape items. Data facilities might expertise 90 % quicker information migration when changing a tape library, with complete value of possession (TCO) projected to lower by a formidable 20 %.

Huawei’s new MED storage seems virtually too good to be true. The first-generation MED items are anticipated to supply a capability of round 24 terabytes per “disk,” permitting a rack system to build up over 10 petabytes whereas consuming simply 2KW of energy.

OceanStor Arctic storage units using the brand new MED know-how are anticipated to debut outdoors China by the second half of 2025, although pricing particulars have but to be disclosed. When pressed for extra data, Huawei declined to share any new particulars till the MED drives turn out to be out there in abroad markets.
