The MD3000i doesn't offer off-host backup. You'll have to back up the data from the server that has it's data stored on the MD3000i. So, if this server is running Windows, you can use a wide variety of backup software solutions. You'll obviously need a storage solution to back up to (obviously not the MD3000i itself). This could be a tape library or if the amount of data is pretty small something like Dell's RD1000 could work.
We have an MD3000i unit with two raid controllers - each have 1x I/O port, 1x I port and 1x O port. I have been tasked with looking at backing up data directly from the Array without using the Network. I noticed the person who installed it also put a SAS Controller card (has two ports) in our Backup server (Win Srv 2003) and connected a SAS cable from that to the I port on RAID Controller 1. However the green lights on the controller card are not on. The MD3000i has picked on a connection and I have assigned it an access LUN. How would I setup the Backup server (once the card is properly installed) to access all virtual disks both RAID controllers of the Storage Array?
