Head of State,
choose nas or SAN in the storage solution,
[Head] Shanghai-jacob 23:02:23
is based on what scene?
【Heroes】Taiyuan @ insist on 23:02:42 There
is little SAN now, right
[Head] Shenzhen-Wenbo 23:04:26
san many
【Head】Shenzhen-Wenbo 23:04:38
nas so what
[Head] Shenzhen-Wenbo 23:04:48
called file sharing server

[Head] Shenzhen-Wenbo 23:09:41
I am talking about two modes of storage
[Head] Shenzhen-Wenbo 23:09:54
Two modes for lun
[Well] Shaoxia stuff have not read the C 23:10:01
ah
[Young Hero] C 23:10:04 is
almost the same. .
[Young Hero] C 23:10:18
(although I haven’t studied storage, either.)
[Head] Shanghai-jacob 23:10:21
DB uses san because it is more efficient? Or why
[Young Hero] C 23:10:22 is
almost the same. .
[Young Hero] C 23:10:29
pair that I don’t even understand. effectiveness.
[Heroes] Taiyuan @ insist on 23:10:33 to
sleep, the installation is too slow, the server installs it yourself
[Head] Shenzhen-Wenbo 23:10:36
compact mode is to display how many storage devices are used,
[Head] Shenzhen-Wenbo 23:10:47 The
rear quilt mode is a fixed value
[Young Hero] C 23:10:57 is the
same as VMware
【Head】Shenzhen-Wenbo 23:11:07
db runs in post-preparation mode
[Shao Xia] C 23:11:08,
which I don’t understand, is whether you want to occupy the number you gave

[Shao Xia] The C 23:11:29
test environment, which I can’t understand, is all prepared
[Shao Xia] C 23:11:35
provincial place that I can’t understand anything
[Head] Shenzhen-Wenbo 23:11:50

[Head] Shenzhen-Wenbo 23:11:56 to
save space
[Heroes] Beijing-Zhao Kaiwen 23:12:19
Minimize deployment
[Head] Shenzhen-Wenbo 23:12:52
Shanghai-Jacob
DB uses san because of higher efficiency? What's the reason
@上海-jacob san can block storage or file storage, nas is file storage
[Head] Shenzhen-Wenbo 23:13:13
db generally uses block storage
[Head] Shenzhen-Wenbo 23:14:28
people, am I offline?
【Heroes】Beijing-Zhao Kaiwen 23:15:32 Go to
bed, you will have so many you still can’t afford a house, a car, and a girlfriend
[Head] Shanghai-jacob 23:15:37 San
can also file storage?
[Young Hero] C 23:15:48
I don’t understand anything, I tell you this is this, when you installed the ASA OVA file before, during the process of importing it, there was one I told you Do you want to choose to bear inferiority complex? That is to save space, because under normal circumstances, it is packaged, Ov will follow this VMX configuration file to give a predefined space occupied by the hard disk, if you choose If it’s the post-positioning, it also becomes complete, then he will directly re-use the number you set. If you say it’s thin, then you will earn as much as you use it. However, he has a problem that her smile will change when the amount of data is too large. This is certain. If you store a lot of storage, it is used to run Didi. Anyway, this is basically a general theory. You know what's the matter, why is it like this, because it is a bare metal disk reading, so the speed will be faster, and the thing that time, although I have not played the group, but Those things are similar, it seems that there is a file system as a bottom layer, so from the point of view of finding the path, it has an extra layer of performance. It may change not to say that it works or not. You can theoretically do it. Your database, don’t you also store things? Then I store things and I store them in nas. Can’t you read them? Yes, it’s just that the efficiency will be lower, because we generally assume that this database requires a lot of reading and writing. It’s an application of Gao, so it’s a great situation to apply the bare metal block as much as possible to store it and resist it directly.

Führer:
The advantages of this FC, the advantages are also disadvantages, the advantages are slow, the disadvantages are also slow. It’s a bit slow and slow. What’s the benefit? He kissed the thing I received yesterday. The faster the thing, the more unstable it is. You know, it’s a real man in three seconds. You’re a thing, is that okay? , If it doesn't work, just tell us a little bit slower, right? It's the same, it's the same, what if the girl says you like 3 seconds? Then he definitely doesn't like him, right, he likes the one for three days, you know what that means, it's common here, it's almost the same, I didn't drive, I belonged to the situation, then you can be labeled as FC. No, but for this thing, you have to figure out a situation, that is, the difference in this camp itself is the first point of competition, and the second difference is the industry it faces. It doesn’t have to use something so fast. It requires stability, right, stability first. It doesn’t matter whether you are so slow or not, right, but if you think about this Internet company cloud computing, why the lock is the first to use this IP san, because of its user group This is it, or else come or leave or leave this, right, so if he has to ask his IP san to provide a high-speed effect, then ip tcp can provide a better one The effect is that FC will slow down instead, so it is different from the market in his group. This thing is right. I used to say that FC has problems and it’s not good. I understand this thing is one-sided, but going forward I wonder how fast the financial industry uses FC, he doesn’t ask for it, right? You open the mobile banking, and you clicked in to manage money several times. How many times did you manage me? Isn’t it? That’s why I ask for his database , It’s not that it’s such a high-intensity effect, so what they require is data, not to be lost, to be stable, and to be stable
[Head] Shenzhen-Wenbo 23:19:08
fc's no packet loss, ip can't do it
Head of State: It’s
not that this theory is completely wrong. IP can do without packet loss. He can really invest in this technology. This technology is called PFC, this pause frame control, and it’s called pauseflow control. Just understand it. The theory is very simple, that is, in the IP field, is the QOS and the job? You just click, don't you want to have eight bits? We generally say that DSCP uses six bits and there is another BIT is ECN. What is it? What is ecn? Once the position is opened, it will generate a no lose effect, and then stop the network from this site and pause the frame network, because this is really pause It's a POS machine or PFC. Anyway, there are a few more. Anyway, you can use this name for PFC. If you look at it online, then the TCP protocol also has the function of flow control in it. What a shit, what we see is this RDMA over tcp, it is no packet loss, you heard it right, IP can do it, but it just needs some equipment that supports these features, go to supply This feature of him, we can’t talk about ordinary routers, how can you run without packet loss, that’s unreasonable, you have to let him support this feature
