Discs were installed in each of the servers (depending on the storage class those are SSDs or SATA). All drives are connected to create a single logical unit. Thanks to the dispersion of data between different discs installed in multiple servers disk we receive the maximum level of reliability, since even in case of failure concerning a single disk or even an entire server, customer's data is still achievable.
Each file is stored in three copies on three different discs installed in three different servers.
