Storage systems configuration on dedicated server for rent

In order to decide on the choice of data storage on dedicated servers, it is necessary to conduct testing and analysis of storage parameters. For different projects may require completely different dedicated server for rent configuration, so it is very important to deal with them. Indeed, because of the wrong choice made, a huge amount of resources has collapsed. First of all, you should deal with the following points:

• identify the characteristics that need to be considered for the growth of the storage system as your project grows. This is very important if the project is aimed at rapid growth, because constantly moving it to a new server is too long and expensive. For example if you need dedicated server with GPU it will be wise to ask for a RAID too;

• understand the reason why it’s more profitable and more reliable to achieve fault tolerance at the software level than at the hardware level;

• find out the correct order of testing;

• learn how to change the IOPS by an order of magnitude by changing just one parameter.

Recovery Rate

Consider a simple two-disk system. If one of the disks breaks, the system continues to work with the second disk, but at this moment it is vulnerable. Being in a state of vulnerability can be very dangerous, because hackers can take advantage of this. Therefore, you need to quickly restore information.

The faster backup recovery occurs, the lower the chance that some files will be lost. To restore information, the working disk must be transferred to a new, workable one. This can be done no faster than the recording speed of this disk, that is, about 100 MB per second for the HDD. In this case, the speed will be even lower if the disk is under external load.

Therefore, it is much easier to optimize this process at the software level. For example, in the case of PStorage, if a disk breaks down, replication of information distributed across the entire cluster is turned on automatically, and there is no need to wait for the disk to be replaced by the administrator.
