SME Server is the easiest possible solution to implement NAS/SAN solutions.
SME Server can function as a NAS (Network Attached Storage) or a SAN (Storage Attached Network), for Windows or Linux networks.
In this capacity SME Server will install RAID 0, 1, 5, 6 systems using any type of hard drive and even low cost SATA hard drives without the need for any type of RAID controller.
The performance of SME Server in this capacity easily out-performs hardware RAID controllers, costing thousands of dollars since the actual computer processor is used to control the RAID.
Another extremely important advantage is that this type of software RAID is very easy to recover. The reason for this is that the software RAID information is written on the hard drives themselves.
This way, in case of server computer hardware failure, the drives can merely be installed in any other computer and the RAID will be recognised.
With hardware RAID controllers this is just not possible as an identical hardware RAID controller is required.
