PPTP-Point to Point Tunnel Protocal Point to Point Tunneling Protocol is one of the most popular Internet protocols, it provides PPTP client and PPTP server, encrypted communications, it allows companies to use special "tunnel" through the public Internet to extend the companys network. Data communication through the Internet, the need for encapsulation and encryption of data streams, PPTP can achieve these two functions, which can achieve multi-functional communication through the Internet. This means that, through the PPTP encapsulation or "tunneling" services to non-IP network can communicate the advantages of access to the Internet. But the PPTP session can not be carried out by proxy, PPTP is a Microsoft and other manufacturers support the standard, it is the PPTP protocol extension, which can create multi-protocol Internet VPN.
IBM x3850-1RC the highlight is the use of a strong performance Xeon 7110N processor and support up to four the number of CPU design. Changes in demand for medium-sized enterprises compared the characteristics of ordinary in the premise of ensuring high performance and provides greater room for expansion. We suggest that this system can be used as the users data center management business logic applications), from the major ISV to use Java or Microsoft. Net Framework development environment, the more customized applications. Using x3850 server, the user can run the upcoming 64-bit applications, and are already widely deployed 32-bit applications. Increase the CPU frequency with the same model number, to enhance machines computing power, while increasing the memory allocation, to ensure that every able-CPU into full play the core performance. Standard in this paragraph is not equipped with hard disk models. As a small database to store the user to buy two hard disk drives RAID1, and a massive database, users need to buy three hard disk drives RAID5, so you can more effectively protect data security, to some extent increase the speed.
