According to SLAService-Level Agreement, SLA) requirements, if the disaster recovery center only needs to meet the remote tape backup function, the bandwidth requirement is Latency: the total amount of time required to move data from one end of the link to the other.

as:var user={"name": "Zhang San", "gender": "Male", "Birthday": "1980-8-8"}An array is an ordered set of values, an array that begins with "[", Ends with "]", and separates values by ",". Such as:var userlist=[{"user": {"name": "Zhang San", "gender": "Male", "Birthday": "1980-8-8"}},{"user": {"name": "John Doe", "gender": "Male", " Birthday ":" 1985-5-8 "}}];A string is a collection of any number of Unicod

Connection query category 1. Self-join query, connecting to the same table2. internal join query, [divided into: Natural join (that is, equivalent join removes duplicate rows, or select the column to be represented after select, instead of using "*" to list all columns), equijoin (that is, use "=" for logical judgment after where), non-equijoin] [During inner join, the returned result set is only the rows that meet the query and connection conditions .]3.

Introduction to memory card knowledge 1. Common memory card related concepts HBA and WWN first introduce what is HBA. The HBA mentioned here is the full name of fc hba, that is, the Fiber Channel Host Bus Adapter. In an FC network, when a host (such as a server) needs to be connected to an FC network or an FC storage device (such as a SAN), an interface card is used, just as an Ethernet Card is required to connect to an Ethernet network. This type of

bucket, and then find the corresponding key value. The advantage of this way is that the more data stored, the more uniform the distribution of the index, so we access the key value of the speed of the more quickly, of course, the details of the storage there are many, we can refer to the knowledge of the hash, here we just remember that the map is stored in the unordered set of key-value pairs . Declaration and initialization Map creation has make functions, map literals. makefunction We have

Very popular to introduce the "signal and system" an article, I like this easy to understand the introduction of advanced principles of the article, see a big paragraph on the formula on the special headache.Lesson one what is convolution convolution what's the use of Fourier leaf transform what is Laplace transformIntroductionMany friends and I like, engineering electronics major, learned a bunch of signal aspects of the class, nothing learned, back the formula test, and then graduated.Let's fi

Before we learned about str, int, float and other data types, such as the name of the Str,name= ' rookie ', then if we a department? Do you also store data in strings? Names = ' Rookie, Zhang San, John Doe ' so save the data, in the call is not very troublesome, such as we want to take the stars, but also to use the string method, it will be more troublesome, or you want each person to take a string of variables, so it is troublesome, how many individ
