memory + server SAS hard disk. 2. I personally think that Intel's CPU in the server CPU field is better than AMD's CPU. If there is any objection, I will say that I am so arrogant (please refer to the CPU performance comparison ), do not trust AMD's advertisement too much. A simple way to compare CPU performance is to compare the price. Do not compare the frequency with the number of cores, and the price is similar to the performance. 3. Hard Disk pe

Iops(Input/output per second) is the input output per second (or read/write count), which is one of the main indicators to measure disk performance. Iops refers to the number of I/O requests that the system can process per second, i/O requests are generally read or write data operation requests. For applications with frequent random reads and writes, such as OLTP (online transaction processing), iops is a key indicator. Another important indicator isData throughput(Throughput) refers to the amou

Because SAS is installed in the "Windows Authentication Mode" mode by default during installation, SAS logon is disabled.If you change the Authentication Mode to "SQL Server and Windows Authentication Mode",

). Obviously, MLC has a larger storage capacity than SLC, but SLC is simpler and more reliable, SLC reads and writes faster than MLC, and SLC is more durable than MLC, MLC can be erased for 1 million times per unit, while SLC can be wiped for 10 million times. Therefore, enterprise-level flash storage products generally use SLC, Which is why enterprise-level products are much more expensive than home products. Technical Features of SSD SSD, compared with traditional disks, has no mechanical dev

materials. Hard drives are solid-state drives (SSD disks, new hard drives), mechanical hard drives (HDD legacy HDD), Hybrid drives (HHD a new hard drive based on traditional mechanical hard drives). SSDs are stored using flash particles, HDDs are stored with magnetic discs, and hybrid drives (Hhd:hybrid hard disk) are a hard disk that integrates magnetic hard disks and flash memory. Most hard drives are fixed hard disks that are permanently sealed and pinned to the hard drive. The disks in the

One, the following is my test results: For the speed limit of 100m below, in fact, the type of hard disk and read and write speed has no effect, but how to limit the speed of more than 150m, or infinite speed, then the hard drive is definitely ssd>sas>sata, so it is recommended to use the SAS disk as a Docker mount partition.Openvswitch The default official document provides a speed limit method "rate li

The serial interface also has the advantages of simple structure and hot-swappable support. SATA2 Seagate joins the NCQ Local command array technology based on SATA and increases the disk speed. SCSI is known as the small Computer system Interface (minicomputer systems Interface), after many generations of development, from early

What are the data warehousing solution software available for selection in the market? What difference does it have? Can you analyze and compare their performance and characteristics? Powerful companies such as IBM, Oracle, Sybase, CA, NCR, Informix, Microsoft, and SAS have launched their own data warehousing solutions (through acquisitions or research and development). Professional software companies such as Bo and Brio also have a place in the fron

Dell PE2950 adopts a modular design to facilitate upgrade management and maintenance and flexible configuration. Users can customize procurement as needed. Its rich management functions provide convenience for small and medium-sized enterprises with insufficient IT experience. At present, a Dell PE2950 with a single intel quad-core Xeon 5405 processor is priced at only 9500 yuan, and a keyboard and mouse are given away, which is very cost-effective. Dell PowerEdge 1, 2950 The Dell PE 2950 proce

I haven't posted any articles for a long time! Hard Disk Selection 1. If the hard disk has conditions, try to select a SAS disk. If there is no bad money, you can choose SSD, funsion-io, and so on. You can also consider SATA based on the selected application environment. I haven't posted any articles for a long time! Hard Disk Selection 1.

temporary tablespace on SSD or using RAID0 + 1 to increase the write speed and performance. Therefore, a complicated SQL statement is selected for relevant testing. It is found that the storage path of TempDB has a great impact on the performance. Test Description: A single temporary table contains 55 million rows, and eight temporary tables are generated. The last eight temporary tables are joined by the select group by clause. The test results are as follows: 1. Local Disk 2X136G 10 k
