IDC room deployment server that's something

A few days ago friends to two servers, an IBM X3650, a DELL R720, as for why choose two different models, this reason is very wonderful (safe, save money), the result found a very strange problem, DELL R720 in operation, whether it is to modify the folder name, or upload data hard disk will have "giggle" is very strange (but when the system does not have such a sound), so the phone contacted Dell after-sales, after-sales do not know what the reason, from the hearing is one of the hard drive sound, so let agents replaced a feeling have a problem of the hard drive, Half-day RAID data synchronization;

The result is a little bit small, but still did not reach the normal level, because it is not possible to determine whether this sound will cause a mechanical failure of the hard disk, and production environment do not dare to do so, so that the Dell agents directly to all Hitachi's hard drive, the sound of a small instant three-fourths, Finally normal (do not know whether this batch of Hitachi hard drives are problematic), to solve the problem;

Hard drive no problem, and began to reinstall the system, downloaded on the internet a so-called Dell official website ESXI5.5 results found installation error, fortunately, the previous night prepared two system disk, a Dell ESXI5.5, a VMware original ESXI5.5, In fact, there is a ESXI6.0 (just in case, be prepared), the results of the installation of the original version of VMware Normal, look at all the hardware equipment, basically working normally, but the hard disk has a warning! My mom's got a problem with the hard drive! Scare me! Access to the ESXi shell to see a detailed log information, fortunately, just because the disk is initialized, about 4 hours or so;

This thought can be finished, the result friend told me he wants to be able to a certain network card directly to a virtual machine to use, this simple directly open a network card direct, the following is about the Dell R720 network card Passthrough method, as shown in:

Select the corresponding network card, directly configured as direct, and then the corresponding virtual machine to add the corresponding pass-through network card can!

When you enter the system, you need to download the corresponding operating system network card driver, and then install it on the Dell website;

Note: IBM X3650 M3 Two network cards can not pass, as for the reason for their own degree Niang!

Get! Call it

And so on "Also ready to go outside to take a breath, drink a cup of tea, and was stopped by friends!" What's going on, the transmission of data between the two physical machines is so slow that it's only more than 300 kb! My first reaction was to lie to me! Thought that the same machine room walk from a switch, can not so slow! But the truth is this!

So look at the configuration of the network card, there is no problem, is not ESXI5.5 driver of the Dell R720 network card support has a problem, impossible ah! (although I didn't use Dell's server much, it's not as bad as ESXi's support for Dell servers!) ), so the degree of Niang a no such a problem ah!

So let a friend asked the IDC room, is not on the switch to do the traffic restrictions, the results of IDC Room said no! Well, the room is not mine, H3C switch is not mine, only from their own server, in order to prove that the network card is not a problem, so I did a crossover line, directly let two server NIC docking, data copy, no problem!

Fk! It seems that the problem is still out on the network, see this tube IDC room of the younger brother should just be able to press the position, Lala cable! (Saturday boss did not go to work), so let him call his boss to understand the situation, the original IDC room new rules of the new server maximum speed of 3M, dizzy vegetables! Seems to have not told the younger brother! Fortunately, just a false alarm!

The new problem has come out, how to solve the flow problem? And friends know a bit behind him to need a few servers, and server and server need to go big data, would like to go through the IDC Room switch, eliminate the cost of their own switch, it seems to walk IDC room switch is not likely! So communicate with friends, bought a gigabit switch 8 ports with Port aggregation (home test environment is also used it, leverage!) ) netgear/Network GS108T v2 support Port aggregation Gigabit smart switch.

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;margin:0px;padding-left:0px ;p adding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" wps15ea.tmp "border=" 0 "alt=" Wps15ea.tmp "src=" http://s3.51cto.com/wyfs02/M01/5C/90/wKioL1UdXHKCxwiYAADZOIhvDS0926.jpg "height=" 224 "/>

Now two server configurations have done a port aggregation on the internal data stream, two gigabit ports bundled, leveraged! This does not take the IDC room switch, and fast!

This server problem, traffic problems are solved!

These two days friends and I complained again! Server performance is bursting! HDD Read/write 100%:

It seems the server is going to upgrade again! Oh!

Summary summary:

It seems that no matter how big the project is, it is important to prepare for the preparation! (The front also asked a lot of friends pre-preparation work is not) is white asked, another is very important to be prepared!
