people use the network can use a dedicated network line, not other online interference. Three. Huawei Home Router Huawei is the world's top 500 companies, of which its NE series routers are the most high-end. The ne5000e router can reach the cluster mode system of 16+64 species. At the same time also has the strength of 40G IP, with 40G capacity, to achieve consumer demand. And its design is

Install the Windows 7 Flagship, C disk divided into 40G, installed system drivers and loopholes used 11G, but also 29G more out. Do not calculate the virtual memory, just installed the computer generally said to install Windows 7 at least 40G space, really so? The new computer hard drive did not change only 80G. C is more than the number of other dishes can be used. Expert answers: Approximately 30~35g's

Recently, a machine equipped with Rhel5.3 40G memory has an Oracle database, the database of the SGA set to 20G, when running a business, a peak of business, find swap frequent swap, CPU 100%,load is very high, basically reflected in insufficient memory. The number of connections at this point is about 600. Calculated by memory: Each connection consumes roughly 5M of memory, so 600 connections only occupy 3G memory, SGA memory 20G, operating system me

network, using the most commonly used 10GBASE-SR transceiver, the longest transmission distance of only 33 meters. After the transformation, the OM3 fiber +mpo connector is used to support the transmission distance of the 10GBASE-SR. and can be within 100 meters distance, support the future next generation 40G or even 100G ethernet. At present, switch manufacturers have introduced 100G Ethernet interface Board and

In the second type and case of desktop virtualization, we explored two architectures for desktop virtualization, hostedvirtual Desktop (VDI), and published Desktop/app. In this article, we analyze the two desktop types of VDI in depth, Persistent and nonpersistent. One definition: Persistent Desktop: Typically, each user is assigned a proprietary virtual desktop. User data and personal settings are saved in the virtual machine. Non Persistent Desktop: a virtual machine is usually selected fro

a MPSL VPN system for the company in Beijing, Shanghai, Guangzhou, Fuzhou and other places in 11 offices to provide MPLS VPN access services. Hu Xiangdong introduced the program, including local access, remote access and regional center, such as the typical access mode. After the project project through acceptance, Tatsu group will realize the internal network seamless connection, has a fast and secure network environment, and can further expand the external network, convenient and partners, su

with other routers on the network. Routers are the core devices that connect IP networks. Classification of routers The current router classification methods are different. There is a certain correlation between the various classifications, but not exactly the same. From the ability points, routers can be divided into high-end routers and low-end routers. The division of the manufacturers is not exactly the same. The router, which usually has a backplane switching capacity greater than

Analysis of the low memory problem of Oracle with large concurrent connections under Linux 2010-01-28 20:06:21 Category: OracleA recently installed Rhel5.3 40G memory machine has an Oracle database, the database's SGA is set to 20G, when running a business, when a business peak, found swap frequent exchange, CPU 100%,load is very high, the basic embodiment of memory shortage. The number of connections at this time is around 600. According to the calcu

Label:Sparse file (sparse files) is not an attribute of SQL Server. It belongs to an attribute of the NTFS file system of Windows. If the data in a large file contains a large amount of "0 data" (which should be viewed from the binary), such a file can be called a sparse file. If you look at this file from a two-dimensional diagram, you will find that the file is like many holes, and that is the origin of "sparse". The problem with this kind of file is wasted space. For example, if you are using

The demonstration required the use of a late pre-release copy of Ciscosecure ACS, the only authentication server that Curr Ently supports PEAP, as well as a Windows XP client. Although nothing under the PEAP specification prevents development of software for Non-windows systems, it's hard-to-see Mic Rosoft taking the initiative to
