Advantages Fairly inexpensive Heterogeneous storage support No additional hardware Can utilize IP WAN Disadvantages Licensed per host Potential different solution for each host Drain on host resources Management overhead when more than a few servers Host: Advantages No host resource usage Any number of hosts High Performance Disadvantages Relatively expensive In most cases requires fibre channel between sites In most cases requires the same high-end storage array at the secondary site. Different solution for each storage platform. Additional components required to provide equivalent features. Array: Where should data protection reside?
