How to improve the availability of the server, what should I do if the server availability is too lo

A very important aspect of a server is its "availability", that is, the server selected can meet the requirements of long-term stable operation and cannot have frequent problems. In fact, it is equivalent to the reliability proposed by Sun.

Because servers are facing users across the network, rather than individual users, it is often required that servers be uninterrupted in medium to large enterprises. In some special applications, some servers have to work uninterrupted, even when they are not being used by users, because they must continuously connect to users, whether they are on or off work, or on weekdays, or on holidays. This is the fundamental reason why servers must be extremely stable.

Generally speaking, specialized servers have to work 7x24 hours uninterrupted, especially like some large network servers, such as servers used by large companies, ** servers, and iqdeweb servers that provide public services. For these servers, maybe the only time they actually work is to turn on once, that is, when they are just bought back and fully installed and configured, and put into official use, and after that, they work non-stop until they are completely scrapped. If something goes wrong at every turn, the network won't be able to function properly for long.

In low-grade servers, the following measures are commonly employed to improve the availability of a single machine.

Through inexpensive disk arrays.

Provides data redundancy.

Function. Disk failure is the main body of server hardware failure, and the failure rate.

Up to 52%. The harm of data loss is also staggering, resulting in a lot of waste of time and manpower. At present, IDERAID can implement RAID-0, RAID-1, and RAID-0+1 in three ways, of which RAID-0 does not have data redundancy function, but can significantly improve the performance of the disk subsystem.

Technology. It can check for two-bit memory errors and correct one-bit errors to ensure high reliability of data in memory and cache.

3.Dedicated server power supply.

It can ensure that the system has a clean electricity environment, reduce the occurrence of various hidden faults, and inferior power supply is easy to cause a variety of strange faults, such as high-frequency crosstalk in the circuit will cause frequent system crashes, and low-frequency ** will burn electronic components.

Invisibly, this type of failure also increases the difficulty of maintenance.

4.Additional measures.

For example, the design of the dust filter and the heat dissipation of multiple fans (some servers also have the function of automatically adjusting the fan speed) can help the server run stably in ordinary environments.

Clustering can improve availability and reduce downtime.

We had a situation where server availability was too low, and we started with 6 full server racks and storage devices, but it was not ideal, the floor space was too large, the power and cooling costs were high, and the maintenance of the circumferential nest was also very difficult.

Later, we tested many times, inserting nytrowarpdrive accelerator cards into each server, so that the storage capacity of the server remains the same, the overall performance is improved, and the key is to save a lot of electricity, heat dissipation and maintenance costs, which we think is very good.

Hope it works for you.

Make a private cloud, dynamically provision, and use other wasted resources.

resides in memory. But when new servers add more and faster memory to meet larger computing needs, memory reliability becomes even more important. IT personnel must be on the lookout for memory failures and take advantage of server features designed to enhance memory availability.

Today's enterprise-class servers use terabytes of 64-bit memory, and these prefabricated modules are designed and manufactured in compliance with the Joint Electronic Equipment Engineering Council (JEDEC) DDR3 and DDR3L (Low Voltage) standards. This makes it easy for companies to buy affordable memory from many memory vendors, but compliance with standards does not guarantee reliability.

The biggest threat to memory reliability is not outright failures, but failures caused by production defects, electrical events, and other physical anomalies can occur. Exactly, the server memory faces.
