Seagate, Marvell, Fujifilm and StorCentric announcements, storage products and storage sustainability


Let’s catch up with Seagate’s recent announcements of conventional recording hard drives and 20TB storage platforms and Marvell’s shipment of 5 billion hard drive controllers, including new controllers for NVMe hard drives. We also include recent research from Fujifilm showing how magnetic tape can improve the durability of data centers. Finally, StorCentric announced its Nexsan Unity Software v7.0 release which includes significant enhancements to strengthen security, compliance, and protection against enterprise-class ransomware.

Seagate has announced that it is increasing production of 20TB Conventional Magnetic Recording (CMR) hard drives with its Exos X20 and IronWolf Pro 20TB hard drives. The IronWolf Pro 20TB hard drive is designed for applications. NAS with built-in rotary vibration sensors and supports user workload rate limits of 300TB / year. The IronWolf Pro 20TB hard drive is shown below.

Seagate claims that the 20TB Exos X20 delivers performance for hyperscale data centers and massive scale-out applications. With 4.16ms low latency and repeatable response times, Exos X20 provides enhanced caching that performs up to three times better than solutions that only use read or write caching. Exos X20 also offers increased Sustained Data Throughput (SDR) of up to 285MB / s and has an average time between failures (MTBF) of 2.5 million. The Exos X20 can be used in its Exos CORVAULT intelligent storage system, which accommodates 106 Exos hard drives in just seven inches of rack space and over 2.12PB of storage capacity.

Seagate also announced its new Exos application platform with a new controller featuring 2sd Generation AMD EPYC processors. According to the company, the Exos AP options with the all new AP-BV-1 controller deliver exceptional compute and storage performance in a single chassis. With two controllers based on an AMD EPYC processor, the system offers high availability or controller partitioning, with the flexibility of a common controller slot allowing connection to additional EXOS E SAS expansion units in matching chassis.

AMD EPYC processors offer a combination of features to help meet the need for advanced storage solutions. In the Exos AP Enterprise Data Storage System Controller, AMD EPYC processors offer 8, 12 or 16 core count for different performance levels. The processors also provide the solution with dedicated PCIe® 4 lanes that provide 200GbE network connectivity and high bandwidth to the SAS controller for faster hard drive and SSD response. Finally, the Exos AP system supports 25GbE on the motherboard

Marvell announced the delivery of its 5 billionth hard drive controller in January 2022. Marvell has been providing data storage solutions for 24 years. The company said its full suite of Bravera HDD controllers and preamplifiers leverage the company’s intellectual property and process excellence, including more than 1,500 hard drive-related patents and 18 generations of Read Channel IP. . The image below is from the Marvell Analysts Day news event.

As shown in the slide, Marvell is working on introducing hard drives that use the NVMe interface and thus able to run on the same PCIe bus as SSDs.

Fujifilm recently informed me of the environmental benefits of using magnetic tapes for cold storage applications in data centers. Data centers generate up to 2% of global CO, according to INSIC 2019 report2 emissions. Information technology (IT) globally consumes around 7% of the world’s electricity production and this figure is expected to rise to 13% by 2030. After processing and moving data, digital storage consumes a significant amount of power. data center energy. Hard drive bays stay on all the time and therefore consume more power than a tape library where data resides on tape cartridges that do not use any power except that required for environmental control until they are needed when moved to a drive to read or write data.

Fujifilm completed a joint project with IDC to estimate the potential carbon savings if data center managers put cooler data on magnetic tape to optimize costs, reduce power consumption, and improve performance. overall total cost of ownership. IDC used its data growth projections (estimated at 27% CAGR) and data lifecycle in energy / carbon consumption estimates (energy consumption increased by 31% on average by 2017 to 2020). IDC also assumed 20,000 large or mega WW data centers by 2025. Calculations are based on type of storage system (hard drive or tape) and CO2generated by MWh. IDC estimated that 60% of the data stored is cold and could be stored on magnetic tape. The figure below shows the resulting estimate.

The IDC / Fujifilm study estimated that migrating cold data from hard drives to tape can reduce carbon emissions by 43% and that the cumulative carbon savings would be 665 million metric tons of CO.2. Additionally, magnetic tape storage is considerably cheaper per TB than hard drives and is typically used twice as long before replacement as hard drives, resulting in a lower total cost of ownership for data storage. . A survey of 1,200 international C-level executives by Fujifilm and Panelbase showed that sustainability is an important factor in business decisions. A study by Brad Johns, sponsored by Fujifilm, found that tape storage consumes 87% less power than equivalent hard drive media and reduces the total cost of ownership for storage by 86%.

StorCentric announced its Nexsan Unity v7.0 software. According to the company, v7.0 includes significant enhancements to strengthen security, compliance, and protection against enterprise-class ransomware. New Unity software now supports Object (S3) protocol, immutable snapshots, object locking, and offers a performance increase of up to 40% (up to 13 Gb / s) compared to version 6.0 from Nexsan Unity. The company says it is getting a 50% increase in onboarding rates from Unity to Assureon, as shown in the figure below. The product also supports up to 100Ge Ethernet as well as 32G Fiber Channel interfaces.

Seagate ships conventional 20TB recording hard drives and new storage system platforms using their hard drives. Marvell celebrates the delivery of 5 billion HDD controllers. Fujifilm shows durability benefits for the tape to store cold data. StorCentric launches its Nexsan Unity 7 software.
