Diskless server memory is not the bigger the better, some people say that memory reads faster, the client virtual disk is still limited to 70M/S or so, what is the use, but increase the true meaning of diskless server memory is to maximize the maintenance of Server stability and performance.

Why do you say that, single said that the hardware, due to the hard disk caused by the card machine, crashes accounted for more than 80% failure, disk failure caused by bad sectors is sometimes not easy to be clearly judged and ruled out. The power supply is followed, because of the memory, there are not a few servers that are damaged by the motherboard.

Large memory cannot be said to avoid 100% of the above problems. However, the probability of such failures can be greatly reduced, with fewer days of business suspension and fewer days spent on credit. Secondly, it can also alleviate the problem of degradation of the aging performance of disk arrays. Under large-memory caches, disks are rarely active. Of course, life expectancy has also increased N years. Instead of replacing the disk in the second three years, the longer the usage time is, the more obvious the advantage of memory is. The bigger the Internet bar is, the more obvious the advantage is, and it is worthwhile for long-term investment.

Look again at the memory to help the game. As we all know, the memory disk is about equal to the speed of the cache. The two SAS arrays and memory disks are virtualized into client disks at the same time. In the following, the speed is 64K, and they reach 63M.

However, the speed of loading CF can be more than 5 seconds. I am actually measuring 7-9 seconds. Why is the memory disk faster than a real disk, like speed, of course, thanks to random memory and burst speed. The same large memory cache is also very helpful for the smooth running of other games.
