For commercial use, in addition to the functional requirements described above, the design documents also include electromagnetic interference (EMI) and electromagnetic compatibility (EMC) certification, security certification, and use environment (including environmental temperature, humidity, salt spray corrosion, etc.) requirements.
In fact, after the above requirements are determined, the next step is to consider selecting a suitable CPU to meet and implement system functions, then,

Table space used to hold InnoDB as a datasheet: More than one file may be involved; The maximum length of each tablespace file must be in bytes (B), megabytes (MB), or gigabytes (GB); The name of the tablespace file must be separated by semicolons; The last table space file can also take a Autoextend property and a maximum length (max:n). For example, ibdata1:1g; IBDATA2:1G:AUTOEXTEND:MAX:2G means

This starts with bit and byte: bit and Byte are translated as "bits", which are measured units of data, bit= "bit" or "bit".Byte= byte is 1byte=8bits, the conversion is 1:8 of the relationship.Mbps=mega bits per second (Gigabit/sec) is the rate unit, so the correct argument should be that the U

-critical workloads. NetApp testing has shown that migrating an OLTP database workload from an environment of a pure SAS hard drive to a hybrid array of SSD and SATA hard drives can reduce storage costs by more than 40% per terabyte and reduce power consumption by more than 25%. With a small number of SSDs you can achieve the goal of accelerating and saving the overall cost. As a result, many enterprise users are more highly respected for hybrid array
