Synchronous disk mirroring can protect data from storage device and channel failures. This solution is ideal for satisfying the demand for non-stop operations. Synchronous mirroring sends write transactions to both storage devices at the same time in parallel, updating both copies of the data before the write operation is confirmed.
Ideal for batch-oriented applications, synchronous mirroring ensures both data sets are kept in synch at all times. With synchronous mirroring, you can also migrate data from older disks to newer disks with no downtime, and failure protection of RAID can be enhanced with the ability to mirror across multiple cabinets.
Synchronous hard drive mirroring traditionally affects server performance, but with a solution from North American Systems International, the storage server can take care of the mirroring operations, which reduces I/O requests and CPU demands on processing dual write commands.
With North American Systems synchronous mirroring solutions, our approach is vendor-neutral and protocol independent, so you can have primary and synchronously mirrored disk from different vendors, even if one is Fibre and the other is iSCSI.
