: Quickly create a copy of a virtual machine through the Vnx writable snapshot feature. Full clone: The buffered IO interface is used to read data from the source file and then write it to the destination file. Reservation (space reservation): Using the NAS API extension to use the permanent reservation feature Extended file stats:vmdk used bytes of file properties New features introduced in the new version Fast clone of a fast clone-Vaai for NFS

If your vnxe system does not have an Internet connection, you can obtain system license files from a computer that has an Internet connection and upload them to the VNXE system. To obtain and activate the VNXE system license: The task you need to complete is to get the Vnxe product ID, and you can vnxe the system's 14-bit product ID/SN on the label on the back of the system. 1, from a computer with Internet connection, use a Web browser to open the

, playing MySQL cluster and Oracle RAC need better hardware and a lot of maintenance costs after deployment, therefore, to take into account the number of visits here is still very large, then congratulations, At least tens of millions of or even billions of PV.Giant companies like Baidu, in addition to the regular MySQL and Oracle database Library, will be in higher performance requirements of the field, a large number of nosql Database, and then the front-end in the DNS, load balancing, distr

This is a series of articles, starting from the basics, and introducing the generator in Python and coroutine (mainly about Coroutine), and detailing the various advanced uses of coroutine in Python, Finally, a simple multi-tasking operating system is implemented with Coroutine.Actually also read this article the study note! O (∩_∩) oGenerator (Generator)What is a generator? In Python, the generator (Generator) is a function with the yield keyword1 defgene ():2A = 13 Print "start executing g

Failure phenomenon: How does the VNXE system without Internet connection obtain and activate licenses? Solution: If your vnxe system doesn't have an Internet connection, you can get system license files from a computer that has an Internet connection and upload them to the VNXE system. To obtain and activate the VNXE system license: The task you need to complete is to get the Vnxe Product ID and you can vnxe the system's 14-bit product ID/SN on the label on the back. 1.

group is a mail-enabled Active Directory group object that contains all the recipients of the properties in Active directory that match the group filter. If you modify the recipient properties to match the filter, the recipient may inadvertently become a group member and begin to receive messages sent to the group. It is important for an administrator to define the filter criteria to reduce the chance of such problems occurring. New Distribution Group: Generally speaking, the distribution gro

into three categories, four categories and five categories. 2) connectors and sockets Each workspace should have at least two information sockets, one for voice and one for data. Pin combinations of sockets are: 1 2, 3 6, 4 5, 7 8. 3) Selection of blocked and unshielded Systems China basically adopts the North American Structured Cabling strategy, that is, the hybrid cabling method with no shielded twisted pair wires and 10 optical fibers. (1) Meaning of Blocking The shielding system is use

impedance to the low-frequency current, while the current at higher frequencies can have a large attenuation effect.four. The difference between inductance and beadThere is more than one turn of the coil habit called inductance coil, less than one turn (lead through the magnetic ring) coil is used to call the bead. Inductance is a energy storage element, and the magnetic bead is a power conversion (consumption) device, the inductor is used for the supply filter circuit, the magnetic beads are u

This is an era of "information flooding", where big data volumes are common and enterprises are increasingly demanding to handle big data. This article describes the solutions for "big data. First, relational databases and desktop analysis or virtualization packages cannot process big data. On the contrary, a large number of parallel software running on thousands of servers need to do this. Many organizations turn to open-source tools, such as Apache hadoop, to handle big data. For example,

Inductance is an energy storage component, while magnetic beads are an energy conversion (consumption) device. Inductance is mostly used in power supply filtering loop, magnetic beads are mostly used in signal loop, and EMC Countermeasure Magnetic Beads are mainly used to suppress electromagnetic radiation interference, while inductance is used to suppress conductive interference. Both can be used to handle EMC
