The system survived the failure of 6 disks in 12-disk RAID 5, and after the failure of the fifth HDD, the array was restored to Online state, and the free space on the sixth disabled hard drive ran out, and the rebuild happened only partially, leaving the array in a degraded but working state.Īs you can see in the screenshots, even after emptying the contents of the LUN, it occupies only 10% of its maximum volume on disk space. We sequentially turned off one hard drive, measuring the recovery time of the array. The usable volume of the array was 20 TB, inside which 10 LUNs were created with a total volume of 9.6 TB. For testing, all disks were combined into a common pool, inside which a RAID 5 was assembled with one virtual Hot Spare disk. Huawei OceanStor 2200 V3 came to our laboratory in a configuration with 12 NL-SAS hard disks of 2 TB each.
Let's test this array survivability feature! With each HDD failure, the OceanStor 2200 V3 controller automatically redistributes data to unoccupied areas of hard drives, and after 30-40 minutes your array is alive and well again, and having lost one HDD, it will survive the failure of the next hard drive. Reliability of the assembled arrays is a matter of pride for Huawei: just imagine - not only does it take 30-40 minutes to restore a 12-disk array, moreover, you can do without a Hot Spare disk at all (as a hot substitution is not a physical disk, but the free space of the pool), so also the traditional RAID 5 will withstand the fall of two, three, four, or & hellip nine hard drives - there would be free space. These terms are not found in the storage settings, so if you are interested in how this works, we offer you slides from the manufacturer's presentation. In the terminology of the developer, RAID 2.0+ technology divides the space of a disk group into chunks, chunk groups, and extents. This could be useful for creating a small fast disk group, but the technology went further - the Huawei OceanStor 2200 V3 controller itself is able to separate data into "hot" and "cold" and move them inside one RAID array to faster media - 15K HDD or SSD. The simplest is the ability to create multiple simultaneous RAID arrays of different types on the same hard drive pool. In the two cases, the controller operates not with physical media, but with the space inside them, and here you have truly unlimited possibilities. And now from these blocks you assemble a RAID array according to any of the traditional schemes - from a simple RAID 1 mirror to RAID 60. It's a completely different matter when you take completely different hard drives and/or SSDs and divide their space into equal blocks, let's say 128 kilobytes each. Of course, you still need to reserve 2 or 3 disks of different types for hot swapping, but this is the reality of traditional RAIDs, and you have to put up with this even in very expensive storage systems. It makes no sense to combine 7200 and 10,000 RPM disks in traditional RAID arrays, when replacing a "brick", rebuilding an array can take up to several days, inside the array all disks are equal, and if you distribute data to "cold", "warm" and hot, please allocate an SSD for hot data and create a separate 10/15K SAS HDD RAID array for warm data. It is desirable to have bricks of the same type and size, and if you pull out one or two, the wall will sway, and if three, even RAID 6 will collapse, taking all the stored data with it. Traditional RAID can be compared to a wall where every brick is a hard drive or SSD.

The OceanStor series is designed to store large amounts of enterprise data, and even the youngest model OceanStor 2200 V3 is already scalable up to 300 disks with a total volume of 2.4 PB, these are file and block access, these are FC, FCoE interfaces and Ethernet with iSCSI support, it is 12 Gbps SAS for head-to-shelf connectivity, a 2-controller design without a single point of failure, and support for block-based hard disk virtualization, a technology Huawei proudly calls RAID 2.0+. The company " ELKO", the official partner of Huawei, provided us with the OceanStor data storage system 2200 V3 for rigorous and comprehensive testing. Following the principle of "more features for less money", Huawei, even in entry-level storage systems, uses technologies that competitors can only find in top-end models. Huawei storage systems are relatively new, and today the Chinese manufacturer successfully competes with brands such as Dell/EMC, Netapp and HPE.
