I plan to use two of the DASD (Sun 3310, 12 * 73 GB disks) to store replicated images of the boot disks from production...
machines. The idea here being that these can be used on the DR site to jumpstart a machine and have it quickly rebuild as a production machine, identical to how it was on the primary site before any disaster.
In terms of the storage devices, what is the best way to utilize the two 3310s? I have 24 disks, totaling around 1.7 TB of raw data. RAID 0+1 seems an option, but the overhead of this just seems obscene. How best can I utilize these 24 disks?
In terms of I/O performance, writing is not a primary consideration, but reading of data needs to be at a decent enough rate to not cause a bottleneck when jumpstarting clients. I also need to consider the fact that the units I have inherited are JBOD and do not have a hardware RAID controller.
