partition number is 16. Therefore, the primary and extended partition numbers occupy 1~4, and logical partitions occupy 5~16. Even if you have only one primary partition (for example,/DEV/SDA1) and one extended partition (/DEV/SDA2) on your hard disk, the remaining two primary partition numbers:/DEV/SDA3,DEV/SDA4 are not assigned to logical partitions. The first logical partition must be numbered starting with/DEV/SDA5.File systemLinux supports many different kinds of file systems. Linux is cap

in the format, where the MBR maximum partition is less than or equal to 2TB, and the GPT partition does not have 2TB limit, the theoretical maximum partition of the EB!Now we know that to create a partition larger than 2TB, you cannot use the MBR format partition table, and to use the GPT-formatted partition table, our most commonly used Fdisk partitioning tool will not be able to use the parted partition tool under Linux !The test environment is:Dell R710 2u ServerCPU 5606 XEONMem 16GDisk 6*1T

Http://www.cnblogs.com/ggjucheng/archive/2012/10/07/2714294.htmlObjectiveMost file systems retain some space for emergencies (such as a full disk space), which ensures that some critical applications (such as databases) have a bit of leeway when the hard disk is full, not crash immediately, giving monitoring systems and administrators a little time to detect. However, sometimes this part of the reserved hard disk space is a bit wasteful. How do I release the space reserved for this part of the s

This new feature, called "Storage space," will take advantage of a physical storage facility to make up the data pool. This data pool will be created using SATA, USB, and SAS hard drives and can use additional hardware extensions. These virtual hard disks, called "spaces", can extend 4TB storage space to 10TB. These storage spaces also provide an elastic layer to solve the problem of errors in different physical media. Another benefit of this featur

The difference between SSD and mechanical hard disk Solid-state hard disk and mechanical hard drive to distinguish between many, first of all, from the shape, the mechanical hard disk is larger than the solid state hard disk, so the weight is heavier than the solid state hard disk, followed by the price, solid-state hard disk price than mechanical hard disk much more expensive. In general, desktop computers are the basic mechanical hard drive, but with the development of solid-state drives, wit

MySQL3.22 limits the table size to 4GB. Due to the use of the MyISAM storage engine in MySQL3.23, the maximum table size was increased to 65536TB (2567–1 bytes). Due to the larger table size allowed, the maximum valid table size for MySQL database is usually determined by the operating system's limit on file size, rather than the MySQL internal limit. The InnoDB storage engine saves the InnoDB table in a table space, which

converted to file_id, which enables accurate row positioning.DATA_OBJECT_ID (usually segment number), which table space,relative_fno->file_id More specific database restrictions see the Official document: http://docs.oracle.com/cd/B19306_01/server.102/b14237/limits.htm#REFRN004--??rowID of bigfile table spacebecause the large file tablespace can only include one file, there is no need to file#-the file ID in rowID. the ROWID format for large file table spaces is:oooooo.

small document management and processingIntelligent search and mining system for heterogeneous dataSuccess StoriesWang Shupeng said the system has a successful application case, is a national ministry of the Big Data management project. The main requirements of this system are:A large amount of information is recorded, generating about 4 billion articles per day (about 4TB);Data retention backup copy, record Data retention half a year;The data can be

User role-based rights management system.Storage mechanism:The mmap file + memory index is used. Memory and cache management is the responsibility of the operating system, which degrades performance when the size of the data set is exceeded. Memory control under Linux can be implemented by configuring user Ulimit-u.Real needs: 1. Need to store flexible semi-structured data for fields. 2. The storage size of billions of records, average 20k per record. 3. Read demand is much larger than write (i

performance will also be reduced, not one upgrade in place, may need to upgrade again in the future. But this kind of collocation for young users, especially for the game, large-capacity program hosting needs of large users, if your budget is not sufficient, but also willing to try to do the operation, in the original volume of the capacity of this disk at the same time with SSDs to improve the performance of the platform, but also suitable.

" still advocate the use of rotating disks (mechanical disks). Frankly speaking, when it comes to manipulating databases, these arguments are often outdated or completely wrong. Today, SSDs offer considerable performance and reliability at a high price. 　　 However, not all SSDs are applicable. For a database server, you should use an SSD designed for server workloads that will protect data (for example, during a power outage). Avoid the use of commercial SSDs designed for desktop and notebook co
