Su Xiaomu was very glad that his knowledge accumulation was barely rich.

Fortunately, the system has carried out full simulation demonstrations in different scenarios in the knowledge materials related to storage.

Only then did he not tremble when he faced this Solaris-based storage operating system that was about to disappear from the stage of history.

The last version of the Solaris system was updated in 2015, which is one of the few updates in the five years since SUN was acquired.

And not long ago, in September, Oracle, which acquired SUN, quietly laid off all the engineers who had taken over from SUN.

Su Xiaomu did not act rashly, he conducted a comprehensive assessment of the system status of this set of storage according to the storage management operation manual.

This includes, but is not limited to, learning about the hardware resources, disk array resources, business traffic, and usage of this set of storage.

The disk array is marked as 200T space, because all hard disk manufacturers try to save trouble and money when producing hard disks, and it is not converted in units of 1024, so the actual size is only: a little more than 181T.

The hardware resources of the storage head are not good, using the processor of Intel Xeon E5, equipped with dual control plus a total of 64GB of memory. ①

However, this set of storage was originally used to store historical backup data, and the performance requirements are not high, and this configuration is sufficient.

Looking at it, Su Xiaomu's heart moved, and he vaguely had some extra thoughts.

Wanshi Small Finance's attitude towards this set of storage is very simple, to ensure that the data in it is moved out intact and without leakage.

After that, it was basically smashed, and because of the stored data, it wouldn't be reversed.

After all, it is the information age, and the importance of data is far beyond the imagination of ordinary people.

According to incomplete statistics, the global storage market is about 100 billion US dollars per year.

Su Xiaomu's slender fingers occasionally tapped a few times on the keyboard, occasionally holding his chin, looking at the screen in a daze.

Over there, Soho and Wan Dai didn't deliberately lower their voices and chat.

"What are you going to do with this set of storage, it's going to get a lot of money, right?"

Soho talked about the processing of this set of storage.

"I'm really stupid, when I was bidding, I was greedy for cheap, and this set of storage hardware plus software plus 3 years of gold medal after-sales service was only more than 500,000 yuan.

At that time, the performance requirements were not high, and there was just a period of time when the wind was mainly promoting localization, so I bought it, to be honest, it was good quality and cheap.

I didn't think about storing important data, so there were basically no failures, which is good, and now I go bankrupt without saying a word. ”

When she said this, Wan Dai couldn't help but shed tears of remorse in her heart.

It's all because she wants to save money and make it cheap, which is why she is like this.

"I have bought a new EMC storage, and now after this set is completed, at most the frame will be dismantled and sold for scrap iron. ”

Wan Dai said helplessly.

"Foreign things are expensive, and the performance of storage in the same space is not much different, but the price is more than 3 times more expensive! Alas, it would be good if the national production capacity was not expensive. ”

Soho smiled, "Do you want to say that a certain domestic product is more expensive if you don't carry it?" (2)

"I don't understand these either, that is, I have listened to two mouths in the financial circle, and the most domestic capital to do is this, and there is a lot of infamy in the financial industry, and it is expensive to die if you can't bear it. Wanda sighed.

It's not angry, it's not an industry, and there will be no intersection between them.

…………

…………

After a morning's effort, Su Xiaomu basically didn't operate directly on the storage.

On the contrary, he often writes and paints, and Su He and Wan Dai can see Su Xiaomu's heart.

After seeing Su Xiaomu's calmness and calmness in building data warehouses and data mining and analysis algorithms, this dedication is commendable.

Soho was relieved.

Speaking of which, what she admires most about Su Xiaomu is: Sao is Sao, but she has no knowledge.

Yes, I just don't have much knowledge, even in my own professional field, I am very low-key, modest, cautious, and not blind.

Even when he was in the money last time, Yang Yu, who is famous in the data analysis industry, held it so much, but he didn't see his tail.

If it is a college student of other ages, it is estimated that it is good to publicize the deeds to the whole world, and waves of media interviews are indispensable.

This is probably Su Xiaomu's most essential quality in addition to Sao, low-key and pragmatic, not jumping.

Su Xiaomu, who came out of the ravine, has no worries about food and clothing since he was a child, and he has never been particularly poor, and his family can barely match the word Yin Shi in the countryside.

From a small mountain village to a small county town to a big city, he always remembered what his mother Cheng Qianwei said, and he can't forget his roots.

So, in fact, this is the factor why Soho always prepares everything for Su Xiaomu......

Well, that's it, Soho stressed in her heart.

After lunch, Su Xiaomu spoke unhurriedly.

"Mr. Wan, I have a basic understanding of some of the modules of this set of storage, because it is based on SAN, that is, based on data 'blocks', so data migration will be more troublesome. ”

He raised a finger as he spoke.

"The first way is to migrate data on your business server, that is, to manually copy and paste it bit by bit, because there is no cooperation from the vendor, so it can only be done.

In this regard, I can help write a small program, instead of manual operation, the algorithm will be optimized for storage, the workload is not large, it is a matter of time, this kind of operation has the least risk, and it is also what I admire. ”

As he spoke, Su Xiaomu looked at Wan Dai.

Wan Dai smiled, "Xiaomu, don't sell it to the two of us, let's talk about the second type." ”

Su Xiaomu raised his second finger.

"The second method is more risky, write a program directly on the storage, migrate the data blocks on the storage, do not need to go through the server, EMC can open the corresponding interface, and the server will directly read and write data to EMC after the end.

The advantage is that it is fast, the workload is small, and it is trouble-free, and the disadvantage is that the risk is particularly large. ”

Wan Dai thought for a moment and asked, "If the operation fails, can you ensure the integrity of the previous data?"

"The worst-case outcome is a crash of the storage single-control operating system, and the data is lossless, but it takes a little time to re-migrate. Su Xiaomu replied simply.

This involves a general definition of storage:

The data of the storage operating system itself and the data of the disk array are completely separated, and if the system is broken, it will be broken, and the data in the array will not be affected.

Of course, after the storage operating system crashes, there is no way to read the data in the array, even if you directly pull the hard disk to read, the data in it is garbled.

Wan Dai waved her hand and smiled magnificently, "Just the second one, I believe in you." ”

(1): Dual control: there are two sets of hosts in a chassis, and the host is about equal to the motherboard + processor + memory, etc.

(2): This may be expanded in the future, maybe for the sake of sensitivity, I have been engaged in related industries for more than 4 years, and I have been exposed to a lot of insiders, which is really ......
