The storage system has two parts: data storage and data management. The data storage part includes: storage controller hardware, disks, adapters, network transmission channels, RAID management, LUN management, etc. The main function of this part is to provide basic raw data storage services, such as storing data in the corresponding LUN or Read from it. The data management part includes: Tier, Snapshot, Clone and other data processing functional modules.

The data management part is mainly responsible for some high-level data processing, just like the social needs hierarchy pyramid. The lowest needs are survival, food and clothing, and clothing. This layer corresponds to the basic storage function of the storage system for data, such as to a piece of data. Data is stored in the disk; further up are higher-level needs, such as not only food and clothing, but also good food, sufficient taste, and rich material, so that you have everything you want. This corresponds to the evolution of storage systems for data storage, such as making multiple hard disks into RAID to improve performance, and dividing LUNs to make space allocation more flexible, and hardware configurations are becoming more and more powerful; however, people's needs are always getting more and more demanding. Crazy and boring, not satisfied, but also pursuing spiritual enjoyment. For example, if you have too much money, go to the streets to spread it, or pretend to be a beggar. This corresponds to more advanced processing of data in the storage system, such as Mirro, Snapshot, etc., and even some flashy functions.

 

The data management part can be divided into two categories: pre-processing and post-processing of data. Pre-processing refers to the initial processing of the data before it is written to the disk, or the storage space of the data is prepared in advance before being written to the disk for storage. Examples of pre-processing are: Post Deduplication, Thin Provision etc. Post-processing means that after the data is written to the disk, the functional module reads the data for processing, and then writes it back to the disk. Typical examples of post-processing include: BackGround Deduplication, Data Migrating, etc. Some functional modules include both pre-processing and post-processing, such as Snapshot. The generation of Snapshor is a post-processing process, but once the Snapshot is generated, each affected IO will also go through an additional pre-processing process, such as the CoW process, before being written to the hard disk; another example is that MinroMiror can be executed synchronously. It can also be executed asynchronously in the background. The former is pre-processing, while the latter is post-processing.

RAID, which stands for Redundant Array of Independent Disks, is also known as “disk array”. It is essentially a system that forms a large disk by combining multiple independent disks together, thereby achieving better storage performance and higher reliability than a single disk. Here are some common types of RAID:

 

RAID 0: Combines multiple disks to form a large storage capacity. When we need to write data, the data is divided into N parts, and N disks are read and written in an independent manner. These N parts of data are written to the disk concurrently, so the execution performance is very high.

 

RAID 1: When writing data to the disk, the same data is written to two disks without distinction, which are written to the working disk and the mirror disk respectively. Therefore, its actual space usage rate is only 50%, and two disks are used as one, which is a relatively expensive solution.

 

RAID 5: This is currently the most used method. Because RAID 5 is a solution that takes into account storage performance, data security, and storage cost.

 

RAID 6: In order to further improve the high availability of storage, people have proposed the RAID 6 scheme, which can also guarantee data recovery when two disks are damaged at the same time.

 

RAID 10: RAID 10 is a combination of RAID 1 and RAID 0.

 

Each type of RAID has its specific application scenarios. Which type to choose depends on your specific needs, such as data security, read and write speed, storage space, etc.

 

Among them, megaraid 9560 8i and megaraid 9560 16i are highly used RAID adapter. It is based on SAS3908 high-port-count PCIe 4.0 x8 RAID-on-Chip (RoC), and its performance is twice that of previous generations of products. 9560-8i has Tri-Mode SerDes technology, which allows NVMe, SAS, or SATA devices to run in a single drive bay, thereby achieving endless design flexibility.

Current magnetic disks can be divided into single-disc disks and multi-disc disks. The former has only one disk in the disk body, while the latter has multiple disks. As mentioned before, data can be stored on both sides of each disk, so each disk needs two heads, each reading and writing on one side. However, one thing must be clarified: the disk only allows one head to read and write data at a time. In other words, no matter how many platters and heads there are in the disk, it is impossible to improve the throughput and IO performance of the hard disk, but can only increase the capacity. However, many people are already committed to changing this status quo, hoping to enable the magnetic heads to read and write concurrently within the disk, which is equivalent to forming a RAID between the disks and the disks to improve performance. However, this project has not yet been able to Application products.

 

Factors that affect hard drive performance include the following:

(1) Rotation speed: Rotation speed is the primary factor affecting the throughput performance of the hard disk during continuous IO. When reading and writing data, the magnetic head does not move. It depends entirely on the rotation of the disk to sense the data in the corresponding sector to the magnetic head. Therefore, the faster the disk rotates, the shorter the data transmission time.

 

In the case of continuous IO, the number of head arm seeks is very small, so to improve the throughput or IOPS value, the rotation speed is the primary influencing factor. At present, mid-to-high-end hard drives generally run at 10,000 rpm or 15,000 rpm. Recently, some manufacturers are trying to achieve 20,000 rpm hard drives, and they already have finished products, but it remains to be seen whether they will be widely used in the end.

 

(2) Seek speed: Seek speed is the primary factor affecting disk random IO performance. In the case of random IO, the head arm needs to change tracks frequently, and the time spent on data transmission is very small compared to the time consumed by track changing, not at all in the same order of magnitude. So if the head arm can change tracks at a very high speed, it will increase the random IOPS value. The current average seek speed of high-end disks is below 10ms.

 

(3) Single disk capacity: Single disk capacity is also an indirect factor affecting disk performance. The higher the capacity of a single disk, the greater the amount of data in the same space, that is, the greater the data density. Under the same rotation speed and seek speed conditions, hard drives with high data density will show higher performance. Because under the same overhead, a hard drive with a high single-disk capacity will read more data. At present, manufacturers have developed hard drives with a single-disc capacity of more than 300GB, but they have not been put into use yet.

 

(4) Interface speed: Interface speed is the least important factor affecting hard disk performance. The current interface speed theoretically meets the highest external transmission bandwidth that the disk can achieve. In a random IO environment, interface speed is even less important, because the bottleneck is almost entirely seek speed. However, high-end hard drives use high-speed interfaces, which is a common practice.

In the vast realm of networking technology, understanding network card models can be a daunting task.

 

1、The model number contains "T": the interface type is Ethernet interface. For example: I350-T2, X540-T2, X710-T4

 

2. The model includes "F" and "D": optical fiber interface, used to connect to optical fiber networks, with the characteristics of high-speed transmission and stability. Common abbreviations for optical interfaces: SFP+, SFP28, QSFP, etc. For example: I350-F2, X520-DA2, E810-CQDA2

 

3. The model number contains "SR": the network card comes with its own module, and the modules are usually divided into single-mode and multi-mode. Single-mode is often used for long-distance transmission, and the wavelengths are: 1310, 1550, and 1490. No light can be seen when the power is on. Multi-mode is often used for short-distance transmission. The wavelength is 850nm. Red light can be seen when the power is on.

 

4. Finally, the numerical digit at the end of the model holds the key to understanding the quantity of external interface connections. The last number 1 or 2 or 4: the number of external interface connections. For example: X520-DA1, I210-T1, I350-T4, X710-DA4, X520-DA2.
