Foreword
First of all, this is not a typical NAS product out of the box and evaluation article, which involves a lot of features and settings may not be able to meet the home environment, just for everyone to buy storage products reference, I non-computer and network related personnel, some Setting may not be professional, welcome criticism
I am a man and a hobby girl. I opened a studio with my classmates a few years ago. I mainly do the editing and grading of kang (ri)/shen drama (ju). All the original project files and materials All the libraries are stored on the server of the company, but unfortunately this year the company requires that all non-company project files be stored on the company's server and only the data can be released.
Device SelectionAccording to their own work flow and data flow situation summarizes the equipment requirements:
0. Does not include hard disk, the price is less than 10,000 yuan;
1.8 disks or more (there are 10 spare 3T hard disks in hand);
2. Be able to provide raid6 or other more secure storage support;
3. Support for virtualization, although currently only used for storage, but it is not excluded as an all in one server in the future;
4. Can provide smb share, sftp, iscsi, or provide web-side access, upload, download files, Shenma entertainment features, mobile phones, online transcoding and the like do not need;
5. There pci-e interface, can support 10GE network card expansion (optional requirements);
6. The device can be connected to a mouse and mouse display, and the stored contents can be viewed directly on the device (optional requirements);
7. This device can not wait for orders, from the order must be sent to me within 7 days.
8. Have good after-sales support, it is best to provide on-site service.
Began to prepare for the selection from the finished nas, and successively phased out the qnap TVS-871T and TVS-1282T. However, when I put the model into xbaozhong search
TVS-871T_ Taobao search TVS-871Ts.taobao.com direct link TVS-1282T_Taobao Search TVS-1282Ts.taobao.comDirect link Later I saw the group ds1815+ gave me a feeling of buying software to send hardware.
Ds1815+_ Taobao search ds1815+s.taobao.com direct link After preparing their own diy a nas, but unfortunately the appropriate chassis is not easy to find. Supporting 8-bit NAS tower chassis are all itx motherboards, so that the future will not be able to expand, and the NAS chassis supporting atx motherboards are all rack-mounted, and will catch up with the studio’s original place and will not renew the lease. It is no time to attend to this matter (later there was a new cabinet where it could be racked up, but this is already a hindsight).
Storage chassis _ Taobao search storage chassis s.taobao.com direct link Choosing to store this thing seems to have fallen into the Ganges (+1s). When the studio moved, it was with the dell's dealer Tucao next door. People said directly, I wiped out what you wanted and we had a direct recommendation to me. Dell t330, roughly looked at the configuration and the price, I feel pretty good to go straight to the card box.
DELL PowerEdge T330 - Taobao search DELL PowerEdge T330s.taobao.com direct link 
First of all, this is already pseudo out of the box. It took two months to issue this article. The goods weighed 30 kilograms and the box was very large. It is recommended that the two should move.
System Configuration: CPU: Xeon E3-1220 v5
Memory: DDR4 2133 ECC 8g*1
Array Card: DELL PERC H730
No internal hard disk
After unpacking, it contains a front panel grille for the t330, a number of installation guides, a number of installation manuals, a disc for the dell omm tools and documentation, and a power cord.
Well, to take a 45 degree photo, the side panel of this cargo is opened from the right side instead of the normal atx host is opened from the left side, the bottom is 8 hot-swappable hard disk cages, and now no hard disk is installed, and the hard disk is installed therein. Plugging.
On the front panel, from left to right, the power button, reset button (need to use paper clip), uid identification button, led panel and operation button, two usb interfaces, one of which is directly connected to the idrac system, of course, can also be normal by the operating system. transfer. The led panel is blue when the system is normal. If the system has an error, such as a disk failure or fan failure, it will become amber.
Here you can extract an information tag with the product serial number and quick service code. The company's asset tag can also be posted here.
It's really big from the side
Io port on the back of the host, originally intended to set double 495w power supply, but was told to choose dual power supply can only be scheduled, to wait 1-3 months, anyway, the probability of power damage is not high, but the single on it, this single The power supply should be Delta 80plus bronze. The system includes four usb2.0, two usb3.0, two bcm5720 Gigabit network cards and vga and rs232 interfaces. The ones blocked by the plug are the dell idrac network ports and the sd card (vflash) interface idrac of the T330. Through the two Gigabit Ethernet ports, this expansion interface card does not matter. Next to that is a built-in cooling fan, in addition to power, the entire system cooling on this fan, the power looked very scary, but very quiet, perhaps the t330's initial design is placed in the office area.
Come to a close-up of the front panel net cover, this net cover and the side panel have the mechanical linkage, if the net cover locks the side panel also cannot open. However, it is also an anti-gentleman who does not defend the villain.
Hold down the side panel handle to open the side panel directly. No tools required.
After opening it, the main board was covered by a wind shield. Inside the side panel there are instruction and disassembly instructions for the system equipment. The side panel is very heavy, at least three pounds.
The internal interface is roughly described.

Using a one-dollar coin to show the hot-swap hot-swap backplane thickness relative to some brands of NAS products is simply conscience.
System disk selected intel 520 120g grace ~ to install a system is certainly enough, here is to explain the dell t330 drive position and hot-swappable disk drive disk drive shelf compatibility issues, a Ruike brand to install No, it can't get stuck, but some miscellaneous disc trays can be installed smoothly. I use a double-sided tape to fix the solid on the plug of the drive. In addition to t330 power supply to the motherboard back to the hard disk backplane power supply line, it only provides a sata interface power supply × 3, but the motherboard has a 6p power output is said to give graphics cards or other power needs of the pcie equipment, but this The part number of the root power cord and the maximum output power of this port I did not find.
Hard disk installation, 15 brain pumping bought 16 Seagate NAS disk, the results have not been used up to 17 years. As for the purchase of Seagate, the total generation of Seagate is opposite to the company. The company bought at least more than 1,000 disks from him. So if it is bad, a phone person will bring a new disk directly without any nonsense.
The hard disk model is the NAS disk of Seagate ST3000VN000 5900 rpm, but it seems that Seagate has already given up the follow-up product of the 5900 rpm low-power hard disk. The latest model is ST3000VN007
ST3000VN000_ Taobao search ST3000VN000s.taobao.com direct link 
Mount the hard disk
Finally cover the front panel, there is no feeling of Optimus masks.
Configure the array Because at the time of writing this article, this storage has been put into production environment, so I use another dell server to demonstrate how to configure the array, T330 is actually a 7 3T hard disk composed Raid6 array as a hot spare, the final formatted capacity It is 13.6TB.
When you press ctrl+r, you will see this interface in a few moments. The disk that has been configured with raid1 is the system disk of the server. Let's focus on the unconfigured disks below.
Select the top PERC H730 MINI Array card, then press F2 and select Create New VD.
Select raid6 in raid level in the new expanded interface. Of course, other raids can be selected based on actual requirements. H730 supports raid0, 1, 5, 6, 10, 50. Then select the disk that needs to set up the raid array on the right side, and finally leave one unselected, because we want to leave one disk for hot backup, don't worry about ok, and then enter the advanced panel to set something.
Here's the setting to say:
Strip size: RAID reads and writes store data on each disk in the RAID array. The Strip name is “stripeâ€, which refers to the length of each segment. The available options are: 8KB, 16KB, 32KB, 64KB, 128KB, 256KB, 512KB, 1MB (Note: If configured as raid5, 6, the minimum size is 64KB) If the usage is diversified, 256K is recommended. If it is mainly used to store large files, it is recommended to use 1MB. I use 512KB here.
Read policy: There is No Read Ahead. Read Ahead, two options. Generally choose Read Ahead.
Write policy: Write Through (write data directly to the hard disk in the RAID array). Write Back (Writes data to the Memory Cache of the MegaRAID card before writing to the hard disk in the RAID array). Two options. Generally choose Write Back.
Disk Cache policy: Enabled (data is read and write through the hard disk comes with Cache). Disable (data in the read-write process does not come with the Cache on the hard disk). Unchanged (keep the current hard drive Cache policy). Three options, generally select Enable, but here DELL's dealer reminded me: If you use non-DELL original hard drive, you must select Unchanged.
Force WB with no battery: The memory Cache that is forcibly written to the MegaRAID card without a battery is generally not checked.
Initalize: Initialize the array, not selected here.
Configure Hot Spare: Configure Hot Spare Disk, Select Here.
At this point you will be asked to erase all the data on the disk after you click OK. Click ok.
At this time, you configure the hot-spare disk and select the disk that was not selected earlier. Click OK.
After the array is complete, but do not worry, select the array and press F2 to select Initialization--->Start Init. At this time, the array card will start to initialize the disk, it is not recommended to select Fast Init. The general initialization time is 5 - Between 20 hours.
System/Driver/Management Software Installation:The system selected windows server 2012 r2 standard installation process and windows 8.1 no difference, skip
After loading the system, go to Dell's official website, enter your Quick Service Code, you can quickly locate your machine's driver, manuals and related downloads.
In fact, after installing Windows Server 2012 R2 basically no longer need to install additional drivers. If you want to install only install the Dell OS Driver Pack on the line, this installation package can put all kinds of drivers all-in-one, but it is strongly recommended that the bios and the array card And idrac life cycle controller firmware upgrade to the latest.
Another one to install is MegaRAID Storage Manager This is the management software of the array card. The h730 is actually the vest of the Lsi 9361-8i array card. This software can be downloaded for free from the broadcom official website. Uh-huh, it's broadcom, because after lsi was acquired by avago, avago acquired broadcom. The new company is called broadcom (who is not called avago, whoever buys it).
As far as the software is concerned, there are too many functions and it is necessary to open a topic.
First come a network topology, because the actual deployment is already in the new office
The new office is located in a building of the Beijing Office. This is only mobile broadband, and we only used the company for a day to directly complain to the Ministry of Industry and Information Technology. The reasons are as follows:
Later, mobile customer service replied that we can not meet the public network ip, we recommend that we directly disassemble the network. But later did not split, through the relationship between the introduction of Gehua to install a hundred trillion broadband, the upper and lower levels of reciprocity and there is a public network fixed ip of the original network is still kept, watching video yo.
This building's fan room, Gehua broadband optical delivery is here, you need to pull their own network cable to their own room.
The router is selected MIKROTIK RB750GR3, the main reason is cheap, cheap, cheap. And to meet the functions I need: firewall and L2TP vpn server.
Rb750gr3_ Taobao search rb750gr3s.taobao.com direct link However, this product also has its disadvantages. Because there is no hardware switch, the lan forwarding performance is not good. If there is a large amount of data exchange in the intranet, it is recommended to connect to the switch. I chose the huawei s5700-28p-li-ac switch.
S5700-28p-li-ac_ Taobao search s5700-28p-li-acs.taobao.com direct link 
Because the equipment of a company’s company in the engine room has not been removed, the equipment cannot be put into the cabinet yet.
Thanks to the photos taken by our late big sister. At the time, I was wearing a network cable with the master of Gehua, and my late sister moved all the equipment from the downstairs to the computer room. (This big sister has CCNP hanging.)
Smb share and sftp shareWindows smb sharing way everyone will skip, here I mainly talk about how to build sftp server under windows. Why do you want to do sftp, because there is a project in the United States photography studio to pass the raw file to my side to do later, the other party insists on using sftp as a transmission scheme. The popular tutorial on the Internet is built using openssh, but I haven't succeeded in this stuff. Another solution is to use serv-u, but the licensing price is almost able to buy 10 dell t330 and I do not like to use cracking software in production environments. Later, someone suggested me to use Bitvise ssh server in a scientific networking group.
First of all, Bitvise ssh client can be used for some scientific Internet access functions, so that downloading Bitvise ssh server from the official website requires scientific Internet access.
In addition to opening the installation window, the installation window will pop up a command line window, do not close, agree to the agreement and click install.
Then ask you to install standard or personal edition, this standard edition is charged, the personal edition is free but has the functional restriction, after you let you input the name, this fills in casually, then click ok to begin to install.
Enter the main interface and click open simple settings
Then ip selects ipv4 port 22 (the default ssh port) Open windows firewall Select Open port for all computers (open only for subnet by default)
Unchecked in the second tab (do not allow windows account login)
On the third tab, click Add to add the virtual account.
Fill in the name and password in the shell access type select noshell access, root directory select the directory you want to share click Ok.
Return to the upper level and click save changes to save the settings. Finally, click start server on the home page to start the sftp service.
Because I have a fixed ip and the router has mapped port 22 to the server, I can use flashfxp, filezilla, and other ftp (sftp) clients to connect.
experience feelings
First a hdtune test chart, the background is still transmitting data, so the result is not ideal, for reference only
One hundred trillion bandwidth test, because the test is still downloading things, so the download speed slightly affected.
Intranet large file transfer rate can be stabilized at approximately 110MB
From the home (China Unicom 100M) through sftp download nas file, basically stable at 10MB/S
Advantages: 1. High performance, high reliability, complete server configuration. 2. Good after-sale (dell next-door on-site service) 3. Hardware Raid card (Although software-defined Raid may be the mainstream of the future, but the current-generation hardware soc program still has unparalleled advantages, and if the worst occurs, Lsi array card data recovery is basically a data recovery company can do, but think raidz, raidz2 may not be able to do. Of course, raid is a business continuity technology of disaster recovery rather than backup technology, important data or to separate Backup to other equipment) 4. The noise is low, but with the engine room this seems to have no use.
Disadvantages: 1. Large size, if used as a home, at least have to prepare 0.5 square meters of the place, if you count the land price, the 0.5 square meters have to value a 2w dollars bar. 2 high power consumption, boot 50 watts or so, peak to 130 watts. 3 configuration is complicated, need to have a certain computer basis, but based on win nas seems to have this problem, open sftp group Hui is a few things, win will study a long time.
First of all, it is necessary to reiterate that this is an atypical storage solution. First of all, it does not have many home functions such as mobile phones, online transcoding, bt, Thunder remote download, and synchronization of various files. Of course, this is just a simple open box text, such as the detailed settings of the array card, regular inspection, fault disk replacement, the use of windows storage pool, shadow copies, FreeFileSync synchronization and backup, idrac life cycle control system use , And mikrotik router firewall, qos, vpn settings, etc., this is not detailed, if you can I will start again in the future.
