The Fusion drive technology was presented by Apple at its 2012/10/23 day product launch. This technology can make the performance of the hard disk close to SSD solid-state drives, but it can provide more storage space.
Fusion Drive Technology is a 128GB solid-state hard disk with 1TB or 3TB of mechanical hard disk in a hard disk volume, but can provide faster read and write speed, and mountain lion system seamless integration.

In general, these alternatives have been called "NoSQL databases." ” The fundamental problem is that the relational database cannot handle many modern workloads.

because Web services and applications that use Web services are still running on computers, and since computers have peripherals, we still need an operating system. Windows has added XML support ... All versions of Windows XP and Windows.NET (now renamed Windows Server 2003) provide the best support for a service-driven world.
in particular, Windows 2003 Server is integrated with Microsoft. NET

Microsoft's ASP. NET provides 3 user authentication methods, namely, Windows Authentication, forms (forms) validation, and passport validation.Because of the different authentication methods, so the 3 kinds of authentication methods in the scope of use is also very big difference, Windows authentication method only applies to the site in the controlled environment; That is, more appropriate for the enterprise intranet (intranet). Form certification is
Windows Authentication: IIS performs authentication based on the settings of the application. To use this authentication method, anonymous access must be disabled in IIS.
Forms validation: Use cookies to save user credentials and redirect unauthenticated users to a custom login page.
Passport verification: Performed through a centralized authentication service in Microsoft, which provides separate logins and core profile services for member sites.

Passport on the one hand means that an account can be used in different services to log in, on the other hand, in a service inside the login can be free to roam to other services inside. Frankly, at present Sohu Passport is very bad at this point (but my job is to do it well, hehe)
Sohu's SSO demand is more troublesome, because it has a lot of domain
. A Web service is an application that uses standard Internet protocols, such as Hypertext Transfer Protocol (HTTP) and XML, to be functionally programmatic in the Internet and intranet.
We can also view Web services as component programming on the Web.
In theory, developers integrate Web services into their applications by invoking the Web application Programming Interface (API) as if they were calling a local service. The difference is that the former can be sent over the Internet to a servi

, Nic should be able to handle the total throughput of the OSD hard disk, so recommend a minimum of two gigabit network cards, respectively, for public network and Cluster_network. A clustered network (preferably not connected to the Internet) is used to handle the additional load generated by data replication and helps prevent denial of service * * *, which interferes with the data co-locating group so that it cannot return to the Active+clean state when the OSD data is copied.

Task Independent, Io Independent for Hadoop, ther
In a production environment, we will encounter disks with partitions larger than 2T (e.g. add a 3TB storage), because the MBR partition table only supports 2T disks, so a disk larger than 2T must use the GPT partition tableWhile Fdisk does not support GPT partitioning, we can use parted to operate on GPT disks. Parted function is very powerful, both command line can also be used for interactive, at the prompt input parted will enter the interactive mo
