In the market today, there are several methods to remotely configure RAID adapters. Most manufacturers offer remote GUI configuration. This allows a user to remotely configure RAID systems on a one-by-one basis. It is also possible to extract a RAID configuration from one system and remotely clone it to n homogeneous systems. The homogeneous systems must be identical in the adapter family type, the number of hard drives, and the channels/scsi ids/sizes of the hard drives. For every group of systems that are not exactly alike, a user must resort back to configuring the system(s) on an individual basis which is very time-consuming. In a new enterprise where a company has just bought 1000 servers, this is not likely to be a problem. The 1000 servers are likely to be identical in their hardware configuration. For ongoing business needs, a company's hardware resources will start to deviate from this, becoming more heterogenous, as parts fail and are replaced, as some systems are upgraded, or as new systems are acquired. The user may still want to configure the RAID on the systems pretty much the same regardless of their differences. For example, a simple scenario you can imagine where a customer wants to set all his systems up with a 2-drive RAID 1 array/logical drive for the OS, a single hot spare, and a RAID 5 array comprised of whatever disks remain in the system for data. Assume a customer has 4 systems with the following configurations: System 1 ServeRAID adapter, 6 9G drives on channel 1 System 2 ServeRAID adapter, 6 9G drives on channel 3
