SPOILER ALERT!

In SD Card accidentally deleted Video recovery ask a veteran inside the IT business, what is the biggest difference in between storage and also other IT products? He will undoubtedly inform you: 'The very first criterion for storage products is: Don't lose data!'
Consider that a startup corporation, the accurate registration of customers and content data brought by the long-term promotion and diversion of tens of millions of yuan stated that it'll disappear overnight, which can be tantamount to cutting the throat on the enterprise. Within the cloud era, data would be the foundation of enterprise organizations. All production and promoting activities are really about information. Each and every enterprise is generating data, saving information, analyzing information, and operating hard to mine information. Higher value. Even if there is certainly a problem together with the computing and network gear, it really is normally essential to restart it and continue to utilize it, which affects the progress in the work and will only make the user really feel unhappy and not fatal for the enterprise. Because the final location of data, storage items are various. It should be a role in the bottom line. The personal computer room is often suspended due to energy outages, all-natural disasters, and so forth., but no business is prepared to hear the outcome of 'the information can't be located.'
How can people today not be attacked if they drift in rivers and lakes? Actually, the old rivers and lakes all comprehend the truth: getting a knife could be the norm, but never drop your life! This sentence is translated into the language of the storage business, that is certainly: storage as a complicated program composed of electronic and mechanical components, no component is by no means failed, we will have to technically resolve the component failure (hard disk, power supply, interface card, and so on.) ) Causes any possibility of losing data.
In contrast to Internet-based organizations which are struggling to monetize user data and create worth for themselves, Huawei Storage regards enhancing reliability because the most important principle of item style to assist consumers do away with information safety issues that businesses face in the long-term improvement.
Take the Zhejiang Telecom Cloud Resource Pool project as an example. The project started deploying Huawei Cloud Storage in December 2014, with almost 10PB capacity and numerous nodes. It has been operating safely and fault-free for more than 1300 days. How does Huawei storage guarantee reliability? From the reliability of components and nodes for the cluster and data center level, Huawei's cloud storage has accomplished lots of points. In detail, I'm afraid that I can not finish it for three days and three nights.
▲ Huawei Cloud Storage Reliability Architecture Overview
Currently we will focus on four points:
1
The difficult drive is so precious, how you can enable it do every day upkeep?
Sub-health testing, do a very good 'physical examination' to prevent future difficulties
As all of us know, a classic challenging disk can be a precision device, and slight vibration, temperature changes, and even air pollution can cause the difficult disk to malfunction. Considering that it's a complex technique, the motors and media with the difficult disk will have to have great monitoring and management measures. Huawei FusionStorage cloud storage offers efficient information challenging disk scanning function, periodically reads and scans the effective information with the tough disk. If the scan finds negative sectors, it attempts to 'read repair' to repair the failed sector. If all redundant copies of your information are unavailable in the identical time, the poor sector are going to be marked and an alarm might be generated to prompt the method to perform information repair at the application layer to generate an access error. The Huawei Cloud Storage Program can also determine irrespective of whether the challenging disk is in sub-health state by monitoring the tough disk indicators and IO processing capabilities, and automatically rebuild the sub-healthy really hard disk right after information reconstruction and remove the cluster.
two
The information written to the disc is incorrect, the best way to resolve it?
DIF information integrity verify, right errors in time,
Let the saved information 'do not drop shape'
Within the procedure of data processing, just after many elements, numerous transmission channels and complex software processing, any one of them may perhaps bring about information errors. If this type of error can't be detected promptly, it is actually discovered that the information has been erroneous during the subsequent access towards the data. This phenomenon is known as SilentDataCorruption. Simply because silent information destruction cannot be detected in true time, it truly is hard to recover damaged information, and even irrecoverable.
There are actually numerous reasons for silent information corruption, mainly inside the following categories:
● Hardware failure: memory, CPU, really hard disk, FC or SAS hyperlink, etc.
● Firmware error: HBA, hard disk, etc.
● Computer software bug: solution software program, operating program, application system, and so forth.
Huawei FusionStorage cloud storage is based on the method supplied by the ANSIT10PI (ProtectionInformation) common to verify information integrity during access to the storage program. You'll find multiple PI checkpoints inside the program to verify the integrity on the data on the IO path and correct errors in true time for you to ensure that the information written won't go incorrect.
3
What must I do in the event the really hard disk strikes?
Rapid reconstruction, allowing information issues to heal immediately
There is a classic saying in the movie 'Kung Fu': 'The martial arts on the planet, only break rapid.' When the difficult drive actually strikes, the only factor we can do is restore the data as quickly as possible. Huawei's FusionStorage cloud storage utilizes distributed block-dispersion technology based on underlying block-level virtualization to overcome the efficiency bottleneck with the classic RAID reconstruction target disk (hot spare disk), so that the create bandwidth of reconstructed information no longer becomes the bottleneck of reconstruction speed. It only requires 15 minutes to restore 1TB of information, decreasing the threat of information loss.

four
Who can assure uninterrupted enterprise systems?
FusionStorage correct active-active, system-level double insurance
Look at a worst case scenario exactly where the entire information center ceases operations resulting from force majeure variables which include earthquakes and fires, and also the data can't be retrieved. What really should I do? At this time, the storage gives the active-active function, just just like the highest amount of insurance coverage for the upper-layer small business, all information is saved in actual time in duplicate, and you are no longer afraid of data loss. Nonetheless, it seems that the data is stored in two copies, but for those who are confused about AA, AP, and cluster extension, you'll lose income. RPO = 0, RTO≈0 ca n’t do it, they're all gangsters.
The correct HyperMetro of Huawei FusionStorage, other vendors truly do not.
Carrying out storage is really a meticulous job. From a disk for the overall method architecture, consumer information must be viewed as everywhere to provide high reliability. FusionStorage can do it.
