Su Xiaomu was very fortunate that his knowledge accumulation was barely rich.
What’s even more fortunate is that the system provided storage-related knowledge and materials and conducted full simulation demonstrations in different scenarios.
Only then did his hands not tremble when he faced this solaris-based storage operating system that was about to disappear from the stage of history.
You should know that the last version of the Solaris system was updated in 2015. This was one of the few updates in the five years after Sun was acquired.
In September, not long ago, Oracle, which acquired Sun, quietly laid off all the engineers it took over from Sun. Solaris existed in name only, and was in trouble.
Su Xiaomu did not act rashly. He made a comprehensive assessment of the storage system status according to the storage management operation manual.
Including but not limited to understanding the hardware resources, disk array resources, business traffic, usage, etc. of this storage set.
The disk array is marked with a space of 200t. Because all hard disk manufacturers are trying to save time and money when producing hard disks, they do not convert in units of 1024, so the actual size is only a little more than 181t.
The hardware resources of the storage head are not very good. It uses an Intel xeon e5 processor, equipped with dual controllers and a total of only 64GB of memory. 1
On the contrary, this storage is originally used to store historical backup data, and the performance requirements are not high, so this configuration is considered sufficient.
As he watched, Su Xiaomu's heart moved, and he had some extra thoughts.
Wanshi Small Finance's attitude towards this storage is very simple, ensuring that the data inside is migrated out completely and without leakage.
After that, you basically just smash it and hear the sound. Because the data is stored, you won’t have to use a second hand.
After all, we are in the information age. The importance of data far exceeds the imagination of ordinary people. Countless companies worry about data.
According to incomplete statistics, the global storage market is approximately US$100 billion per year.

Su Xiaomu's slender fingers occasionally tapped the keyboard a few times. Occasionally, she held her chin up and looked at the screen in a daze.
Over there, Su Ho and Wan Dai chatted in a low voice.
"What do you plan to do with this storage? It will cost a lot of money, right?"
Su Ho talked about this storage process.
"I was really stupid. I was looking for cheap when I invited the bid. This set of storage hardware, software, and three years of gold medal after-sales service only cost more than 500,000 yuan in total.
At that time, the performance requirements were not very high, and there happened to be a period of time when the trend was to promote localization, so I decided to buy it. To be honest, it was of high quality and low price.
I didn't intend to use it to store important data, so there were basically no failures, which is good, but now it went bankrupt without saying a word."
When she talked about this matter, Wan Dai couldn't help but shed tears of regret.
It's all her fault that she's trying to save money and be cheap, which is why she's like this now.
"I have already bought a new EM storage. Now that I am done with this set, I will at best dismantle the frame and sell it for scrap metal."
Wan Dai said helplessly.
"Foreign products are expensive. For storage of the same space, the performance is not much different, but the price is more than three times more expensive! Alas, it will be great when domestic products can be affordable and not expensive."
Su Ho smiled and said, "Are you trying to say that if it is made in China, it is more expensive if it is not portable?" 2
"I don't understand this either. I just heard a few words in the financial circle. This is the company with the most capital in China. It has a lot of reputation in the financial industry. If you can't afford it, it will be too expensive." Wan Dai sighed.
tone.
It’s not that we are angry at each other, and they are not in the same industry, so there will be no overlap between them.

Throughout the morning, Su Xiaomu basically did not perform any direct operations on storage.
On the contrary, he often wrote and drew, and both Su Ho and Wan Dai could see Su Xiaomu's care.
Having seen Su Xiaomu's calmness and calmness in establishing data warehouses and data mining analysis algorithms, this level of care is extremely valuable.
Su Ho was finally relieved.
Speaking of it, what she admired most about Su Xiaomu was that he was cool, but not very knowledgeable.
Yes, I just don’t have much knowledge. Even in my own professional field, I am very low-key, modest, cautious, and don’t do random things.
Even when Yang Yu, who is famous in the data analysis industry, was so supportive last time when he was in Heqian, there was no sign of him raising his tail.
If it were other college students of this age, it would be better to publicize his deeds to the whole world, and waves of media interviews would be indispensable.
This is probably Su Xiaomu's most essential quality besides being coquettish. He is low-key, pragmatic and does not jump around.
Su Xiaomu, who came from a mountain valley, had no worries about food and clothing since he was a child. He had never been particularly poor. His family in the countryside could barely be considered well-off.
From small mountain villages to small counties to big cities, he always remembered the words of his mother, Cheng Qianwei, that a person should never forget his roots.
So, in fact, this is the reason why Su Ho always prepares everything for Su Xiaomu...
Well, that's it, Su Ho emphasized in his heart.
After lunch, Su Xiaomu spoke calmly.
"Mr. Wan, I have a basic understanding of some of the modules of this storage set. Because it is based on san, that is, based on data 'blocks', data migration will be more troublesome."
He said raising a finger.
"The first method is to migrate data on your business server, which is a manual copy-and-paste operation. Because there is no cooperation from the manufacturer, this is the only way.
In this regard, I can help write a small program to replace manual operations and optimize the algorithm for storage. The workload is not large, it is just a matter of time. This kind of operation has the least risk, which is what I prefer."
While talking, Su Xiaomu looked at Wan Dai.
Wan Dai smiled and said, "Xiaomu, please don't try to seduce us, just talk about the second option."
Su Xiaomu raised his second finger.
"The second method is more risky. Write a program directly on the storage to migrate the data blocks on the storage. You don't need to go through the server. EM just opens the corresponding interface. After the completion, the server directly reads and writes data to EM.
The advantage is that it is fast, the workload is small, and it saves trouble, but the disadvantage is that the risk is extremely high.”
Wan Dai thought for a moment and asked, "If the operation fails, can the previous data be guaranteed to be intact?"
"The worst-case scenario is that the storage single-control operating system crashes and the data is not damaged, but re-migration will take some time." Su Xiaomu answered simply.
This involves a common definition of storage:
The data of the storage operating system itself and the data of the disk array are completely separated. If the system is broken, it will break and the data in the array will not be affected.
Of course, after the storage operating system crashes, the data in the array cannot be read. Even if the hard disk is directly removed and read, the data inside will be garbled.
Wan Dai waved her hand and smiled grandly, "Just the second one, I believe you."
1: Dual control: There are two sets of hosts in one chassis. The host is approximately equal to the motherboard + processor + memory, etc.
2: I may expand on this later, but maybe I won’t say it for the sake of sensitivity. I have been working in related industries for more than 4 years, and I have come into contact with a lot of insider information. It’s really...
