...
Works on Windows 2012 x64 or later, Linux CentOS 6.4, and Ubuntu 16.04 LTS x64 or later platforms. The file system supports . Filesystems support NTFS, ReFS , and the ext family (ext3 or higherand later), and xfs. (Old file systems Older filesystems, such as the FAT family, are not supported).)
CPU
Works with at least 2GHz, 4 core or higher x86/x64 compatible processor.

System memory
We recommend a minimum of that you run your system with at least 4 GB of system memory , with and at least 30% of your physical memory usage free. This is because, although it depends on the kernel, 70% Typically, 70% or more of physical memory usage is typically considered to be the point at which the operating system will trigger turns on paging to respond to a low memory shortage. If When paging is triggered enabled on your system, you may experience system-wide I/O performance degradation, so you should consider thiswhich should be taken into account.
Memory buffer size
The memory buffer for replication is used to buffer the I/O load locally, and its size is basically obtained by the following formula
- Size of the maximum bandwidth transferred transmitted per time (in seconds) * Timeout time (in seconds)
For 1 Gbps, you can get about 100 MB/s * 5 s = 500 MB, and you should be comfortable with 500 MB to 1 GB.
If you need to consider the fluctuating bandwidth of the WAN section for DR configuration, use DRX buffering with DRX integration responds to respond to WAN bottlenecks. If you don't have DRX integration, allocate consider allocating a larger memory buffer size than described above (5-10x the memory buffer), and if memory space is not available, consider configuring it as a file buffer if memory is not available (see below).
Disk
The default installation size is 2 GB, including installation files and log files, and if you configure a filebuffer, you'll need additional space of that size.
