TAILIEUCHUNG - Thủ thuật Sharepoint 2010 part 13

Mạng Kết nối mạng giữa các máy chủ trong nông trại của bạn là cực kỳ quan trọng. Tối thiểu, tất cả các máy chủ trong hệ thống phải được kết nối thông qua kết nối gigabit. Các yêu cầu khó ở đây là mỗi máy chủ phải được kết nối bởi một kết nối gigabit với ít hơn một phần nghìn giây của độ trễ. | Hardware Requirements 75 it to the BI group by configuring it to only run the Excel and Performance Point services. Note that you will not see the term server group in Central Administration anywhere it is only a logical concept. Notice also in Figure 3-5 that SQL Server has been exploded out into various logical groupings. The performance characteristics and demands of different databases can vary greatly and in large environments it can be very helpful to configure and manage each one separately. Other Hardware Notes Now that you have gotten the hang of all this hardware the following sections describe a few more considerations to think through before you move on. The Network Network connectivity between the servers in your farm is hugely important. At a minimum all servers in the farm should be connected through gigabit connections. The hard requirement here is that each server should be connected by a gigabit connection with less than one millisecond of latency. This precludes most companies from having a SharePoint farm with servers in multiple geographically dispersed data centers. For many companies the sheer volume of network traffic generated between the members of the farm is overwhelming. In order to better control this traffic they move all of the inter-farm traffic to a dedicated virtual local area network VLAN . This is like the server groups discussed earlier. By grouping all of this traffic it is easier to monitor and administer in the case of any issues. A dedicated VLAN is not a requirement for SharePoint but in a large farm it is often recommended. Network Load Balancers In order to achieve high availability of the SharePoint web applications it is necessary to introduce a tool to do network load balancing. This can be either a hardware-based tool such as an F5 device or an external software solution such as ISA or TMG Server or even something as simple as the built-in Windows Network Load Balancing NLB feature. Hardware-based solutions are .
