for developers, there are two main features of icloud storage: icloud documnet storage, which uses icloud to store user files, such as saving files that some users generate when they use the app, and database files. The second is icloud
Apple unveiled a new ICloud storage space upgrade and cloud computing services at this year's WWDC conference to strengthen ICloud's competitiveness. Replacing the VAIO notebook with a MacBook, or replacing the iPhone with Moto X, is simple, but the data transfer is difficult, which also increases the level of platform loyalty. In recent years, Apple's competitors have introduced a variety of better control
icloud document storage programming is more complex relative to key value data stores, involving customizing document classes, obtaining icloud document catalogs, locating documents in ubiquity containers, saving documents, and resolving document conflicts.
Example: icloud document
Because icloud's free storage space is only 5 G, a little attention to transfer a few video will take up most of the storage space.Specific solutions:1. Non-important content can be stored without backupEach new iphone5 has at least 16G of storage space, and it is sufficient to store general general software and data, and only very important information is put in

One of the biggest obstacles to deploying VDI is creating a storage architecture. First, you must determine whether the virtual desktop uses direct connection to storage or shared storage.
It is very difficult to deploy and manage storage for VDI. Because VDI has high requir
Android provides four data storage methods. However, because the stored data is private to its applications, if you need to use the data in other applications, you must use the content provider (Data Sharing) provided by Android ).
The official documentation has a detailed description: http://developer.android.com/guide/topics/data/data-storage.html
The four data storage methods in Android are as follows.

ASIC can offload all work (TCP and SCSI commands) from within the system CPU. ISCSI HBAs can be purchased from many vendors, including Adaptec, Alacritech, Intel, and QLogic.The iSCSI target is the "server" component of the iSCSI network. It is typically a storage device that contains the information you need and responds to requests from (one or more) initiators. For this article, node Rac1 will be the ISCSI target.Second, the experimental environme

When the two programs work properly, the first address of the shared memory displayed in the Server/Client process is different, because the operating system will allocate its own process space for each separately running program, the process space is represented by an address segment. Each process can only run and operate on the address space allocated to it, rather than cross-process address acce

n what is shared storage
Shared storage, which refers to multiple servers accessing (writing) the same partition of the same storage device. In layman's terms

The method described in the previous article is in the global storage area, which slows down the data retrieval speed and affects the performance, the threads in the device read the data in the shared storage area of the block quickly, and many array elements are read repeatedly in the global storage area. Therefore, f

Thermal migration (hot or live migration)-thermal migration is also called dynamic migration. The virtual machine still works during the migration, and the user can continue to use the virtual machine. This is the type of migration that is described in this article. Thermal migration is divided into the following two types:
