【 Weak current College 】 server use mistakes and how to properly use

Server core is vital to ensure that the device to the network server to high-performance, stable and sustained work has always been a top concern for users. However, in the this issue, we found a lot of users do not have properly configured your server so that the server does not work in the best State. Typically the server configuration of common errors in performance in the following ways.

The server uses the common misconception
Error: server with redundant features without

A lot of high-performance server provides array function, but because users do not understand it, purchase only one hard drive, no data redundancy, lost for storage, security and performance optimization

Myth two: high-end servers using low configuration scenarios

Users purchase high-end server itself can meet very high performance requirements, but to configure a low-speed, smaller capacity hard disk and a small amount of memory that causes the server's overall performance significantly lower

Myth three: do not know the server performance bottlenecks resulting waste of resources

User for the server's understanding excessively one-sided, unilateral recognition of the importance of certain components, give your all to turn inputs, while ignoring the other components of the optimization work that resulted in the performance of these components is not play. From the above analysis can be seen, whether as a result of the user for the server capabilities are not fully understood or in the use and configuration problems, many of the operational status of the server is not optimal. According to the statistics show that the industry in 80 per cent of the server is not optimized design, 90% of servers are not scheduled for system performance monitoring, 95 per cent of the server does not have complete data redundancy, security measures, almost half of the server is not a data backup solution. The server is in a State of health, through the: power supplies, fans, hard drives, controllers, cables, network adapter, CPU, and other critical parts not used hardware redundancy and system security; use of low-speed, compatibility of equipment components, unreasonably configuration memory, CPU, hard drive controllers, and so causing the performance decrease; do not use any network server management software and hardware, system downtime in the event of a failure, management has serious flaws.

How to properly use the server

In order to improve the health of the server, Transocean waves is the company specializes in some disadvantages and feasibility of the proposal was presented:

As part of the hard disk storage to increase redundancy hard disks and array control cards, provide data redundancy, and substantially increase system IO performance.

Increased redundancy for the server, use of CPU SMP (symmetric multiprocessor) technology to improve system performance, and increased the Centre deal with redundancy.

Increase the redundant network card, improving network IO performance, to a certain block network connection fails, the server will not be disconnected from the network.

For the server to increase redundancy power module, server power supply capability, when a power supply module when problems occur, the system will not be because of power outages and downtime.

Increasing the RAM for the server to meet the operating system and increasing optimization and application requirements, and improve server performance.

In addition, the need for the server's overall performance balance, avoid performance bottlenecks and security implications. From the CPU processing power, memory size, data redundancy and data storage capacity and network IO IO performance, power supply, fan cooling capacity, system fault alarm capability, charged failover capability to do sections are devoted to the optimization work, e.g. by increasing the hard drive, array cards, increase the cache array card, optional hot-swappable hard drive bracket, use array card more than one channel, select the most suitable array level to meet various read and write performance to optimize storage subsystem.

Depending on your operating system, the number of users, applications, the number of CPUs used to determine the minimum memory capacity, increased remote control card online diagnosis memory running process failures.

According to the system the necessary processing power, system CPU redundancy requirements, number of users, the scope of application to determine the number of CPUs, use operating system performance monitoring software and network management software to detect CPU occupancy will be increased or decreased depending on the situation.

Use the AFT (NIC redundancy), ALB (network load balancing), FEC (Fast Ethernet) and other NIC redundant technology to increase server network IO performance.

Increase the redundant power supply module valid security server power supply to prevent damage due to a single power supply module causes system downtime, increase or decrease redundant fans ensure server system cooling effect, prevents the server from overheating and failure.

In short, carefully check the existing bottlenecks and deficiencies, tailored to optimize each part, eliminate barriers of the bondage performance, fully protected input-output ratio, these can give you the right fit with your server resources, avoid mistakes in entering the server use.
