What kind of server is used in the mine basin

1. What kind of hard disk the server uses depends on what kind of SATA you are currently using.
the onboard SATA
congroller only supports the traditional SATA interface hard disk (SSD or ordinary mechanical hard disk)
if you use the external array card to connect the hard disk backplane, it is best to use the SAS hard disk, because the speed of the SAS hard disk is twice that of the SATA hard disk (12g / s), SAS backplane is also downward compatible with SATA hard disk
of course, you can choose SAS
SSD for better performance

2. Ha ha, friends who are short of money can really use SATA hard disk. From another point of view, the quality of SATA hard disk is not as good as that of SCSI. But it seems that the SATA hard disk is rarely broken, so the SATA hard disk is also widely used in small workstations

the brand can buy western data, anyway, the quality is very good. You can buy the following series:

WD caviar se 16 [high performance]
integrates 16 MB cache, with a storage capacity of up to 750 GB, and a high-speed processor, which provides a perfect solution for microcomputers with a large number of software<

WD caviar GP [energy saving]
3.5-inch hard disk with outstanding energy saving performance< The features of WD caviar se such as low calorific value, quiet operation, excellent performance and first-class reliability make it an excellent hard disk for desktop computers and business storage.

1. The speed of server hard disk is fast

the speed of server hard disk is relatively fast, which can reach 7200 or 10000 rpm, or even higher; Generally, the server hard disk is configured with a large (2MB or 4MB) write back cache; The average visiting time is short; The external transmission rate and internal transmission rate are higher

2. High reliability of server hard disk. Therefore, the server hard disk must have high reliability to support the uninterrupted operation of the server. Now most of the server hard disks adopt S.M.A.R.T Technology (self-monitoring, analysis and Reporting Technology), and hard disk manufacturers adopt their own unique advanced technology to ensure the security of data

3. Most server hard disks use SCSI interface

most servers use SCSI interface hard disks with high data throughput and low CPU occupancy. SCSI hard disk can only be used through SCSI interface. Some server motherboards have integrated SCSI interface, and some have special SCSI interface cards. One SCSI interface card can connect seven SCSI devices, which is unmatched by IDE interface

4. The server hard disk can support hot swap

hot swap is a hard disk installation method supported by some servers, which can pull out or insert a hard disk without stopping the server, and the operating system can automatically identify the changes of the hard disk. This kind of technology is very necessary for 24-hour server

Server hard disk is better than ordinary hard disk in security and earthquake resistance

< H2 > extended data

comparison of advantages and disadvantages between mechanical hard disk and solid state hard disk

1. Data storage speed: from the evaluation data of pconline evaluation room, the performance of solid state hard disk is more than 2 times higher than mechanical hard disk

2. Power consumption: the power consumption of solid state hard disk is lower than that of mechanical hard disk

3. Weight: SSD is lighter in weight, 20-30g lighter than conventional 1.8in hard disk

4. Noise: because the solid hardware has no mechanical parts and flash memory chip, it has the characteristics of small heat generation and fast heat dissipation, and there is no mechanical motor and fan, so the working noise value is 0 dB. Mechanical hard disk is much inferior

Price: up to now (November 20, 2018), 128GB SSD of the brand is about 150 yuan. The price of 1TB mechanical hard disk is only about 280. Compared with mechanical hard disk, SSD is more expensive and less cost-effective

Capacity: at present, the maximum capacity of solid state hard disk is 4T 3.5 inch

7. Service life: SLC has only 100000 times of read-write life, and low-cost MLC has only 10000 times of read-write life. Therefore, compared with SSD, mechanical hard disk has longer service life

At present, there are three kinds of hard disks in the server market: SATA hard disk, SCSI hard disk and SAS hard disk

among them, SATA hard disks are mainly used in the field of low-end servers, while SCSI and SAS hard disks are used in the field of medium and high-end servers

most servers use SCSI hard disk with high data throughput and low CPU occupancy. The external transfer rate and internal transfer rate of SCSI hard disk are much higher than ordinary hard disk. It generally adopts Ultra160 SCSI, ultra320 SCSI and other standards, and the data transfer rate per second can reach 160MB and 320mb respectively. At present, the mainstream SCSI hard disk adopts ultra320 SCSI standard

The SCSI hard disk can only be used through the SCSI interface. Some server motherboards integrate the SCSI interface, and some have special SCSI interface cards. One SCSI interface card can connect seven SCSI devices, which is unmatched by ordinary hard disk interfaces

In general, once the server hard disk is damaged, it will bring immeasurable losses to the enterprise. Therefore, the server hard disk is better than the ordinary hard disk in terms of security and earthquake resistance. In addition, it has the advantages of hot plug and speed, which is why the server hard disk with the same capacity is much more expensive than the ordinary hard disk

5. 1. Raid is good if possible.
2. Which raid? It is suitable for the situation with low security level.
raid
1 has low utilization and medium speed, but it is safer than raid
0. It is suitable for the situation with high data reliability.
raid
0 + 1 and raid
10. By comparison, raid
10 is better than raid
0 + 1.
moreover, raid
10 is better than raid
0 + 1, Generally speaking, hard raid is better than soft raid, but it depends on your specific situation

6. What kind of hard disk the server uses depends on what kind of SATA controller you currently use. The onboard SATA controller only supports the hard disk with traditional SATA interface (SSD or ordinary mechanical hard disk)
if you use an external array card to connect the hard disk backplane, you'd better use SAS hard disk, because the speed of SAS hard disk is twice that of SATA hard disk (12g / s), SAS backplane is also downward compatible with SATA hard disk
of course, you can choose SAS SSD for better performance

7. According to the needs of configuration, suitable for their own configuration is the best configuration
the configuration depends on the amount of tape
the most important configuration on diskless is hard disk and network. Choose the one that suits you< If you have enough money, SSD is better
array sata3, not bad. For diskless machines, you can go to the Internet bar

no disk configuration column, or online.

8. The server can take any kind of photos, but the speed of the hard disk must be high,
this is because the server's reading and writing of data is variable in time and flow
I suggest you consider western data, Maituo and so on if you choose Pinpai————

9. SAS for server is a al data channel hard disk. It has two data line interfaces. The data line and power line are integrated into a whole. There are 29 pins in total. There is a group of 7-pin data lines more than SATA. These two data line interfaces can read / write at the same time or one data interface can read another. It is a real full plex, real simultaneous reading and writing hard disk. The response delay is lower than SATA, and the speed is very high, The maximum speed is 15000 rpm, the data read and write is very fast, the top enterprise disk is used, and the quality is the best. The magnetic head can withstand the test of high load and frequent track change. If it is used to hang up for a long time and download in batches, it is not easy for SATA to cause bad effects. The main board of SAS interface is downward compatible with SATA hard disk, and SATA is a simplified version of SAS with single data interface, It can't really read and write at the same time. The response speed is slow and the speed is relatively low. The cheaper one is 5400 rpm. The server requires stability, data security and fast response speed. SATA is still a little bit worse. It can be divided into black, yellow, purple, red, blue and green grades. I'm dazzled. I'm not lucky. It's easy to buy second-hand counterfeit goods with renovated labels. I won the 618, SAS is the top-level thing. Once the data of the server is lost, the loss is amazing. The price is there, and the quality is there

10. The hard disk of the server? This concept is too general. As far as interfaces are concerned, server hard disks include SCSI, SAS, optical fiber, and SATA enterprise level ones.
SCSI, SAS, optical fiber, and Seagate have a large share. Many IBM and HP hard disks are basically OEM procts of Seagate
