Oceanstar Dorado V6
The OceanStor line includes other all-flash arrays with similarly impressive benchmarks. The OceanStor Dorado V3, for example, allows up to 16 controllers, using NVMe storage to provide 7 million IOPS.
The Dorado V6 is in a class of its own, however; per Huawei, it features “reliable SmartMatrix architecture, five intelligent chips, and the FlashLink® intelligent algorithm, OceanStor Dorado is the first full series storage that supports end-to-end Non-Volatile Memory Express (NVMe) architecture, delivering industry-leading performance.”
The device’s fault-protection systems prevent downtime, even during catastrophic events (though, as we frequently note, any system is capable of failure under certain circumstances). It boasts a one-second switchover time with uninterrupted links in the event of a controller failure and can tolerate the failure of seven of eight controllers across engines without any service disruption whatsoever.
While HDD-based arrays are still the standard for most organizations, flash-based systems have gained market share for mission-critical operations. Solid-state drives are generally faster than hard drives, although NAND-based flash is slower at writing than reading. Even taking garbage collection procedures into account, flash arrays are significantly faster than the fastest HDD-based systems, and modern storage algorithms can prevent traditional SSD issues (such as corruption) from inhibiting performance.
“Huawei OceanStor Dorado V6 all-flash storage system satisfies the data hungry storage requirements of large databases particularly in the carrier, finance, government, and manufacturing industries,” the company states on its website.
While Huawei hasn’t released pricing, interested buyers can contact a Huawei sales office for a quote. The OceanStor line shows a clear move towards higher IOPS ranges in the solid-state array market while emphasizing China’s dominance in the field—while American manufacturers may bristle at the company’s dominance, 20 million IOPS is certainly a laudable achievement.
