The VCN510 supports only RAID1 or NON-RAID. If only one disk is configured, the VCN510
supports only NON-RAID. This section assumes that two disks are configured for the
VCN510.
Description
Two disks are required in RAID 1 mode. If RAID 1 is used,
disks back up each other. After recording data is stored in a
disk, the data will be simultaneously backed up to another
disk, ensuring high data storage reliability. However, the
disk usage of RAID 1 is lower than that of disks that work
independently.
If disks work independently, recording data is stored into
two disks in sequence, ensuring high disk usage. However,
the data storage reliability of disks that work independently
is lower than that of RAID 1.
NO TE
The server will be restarted during the initialization of disks. The process takes about 5 to
10 minutes.
