I've been looking for an upgradable storage solution. Our current needs are 250 GB, and I would like to be able to expand incrementally over the next few years to 2 TB or more (must be a single volume). We currently use SCSI RAID, and I could expand that way. I am also considering the 3ware Palisade iSCSI solution. Do you have any suggestions?
This (scalability) is becoming increasingly easier to do as disk drive densities increase. The choice of cabling (SCSI versus iSCSI or Fibre Channel) is mostly independent of the capacity. Today, there is more selection in SCSI and FC, but that will likely change as more iSCSI disk subsystems are introduced.
