I am trying to find who sells one or more of three types of high capacity storage systems. The first is to store 200 terabytes of security videos with the ability to retrieve a particular indexed video quickly. The second is a very high canacity RAID 5 storage system for off-site data storage of critical data for banks, government tax files, etc. The third system is also for off-site data storage that can grow to a petabyte size for general public storage of files. Your help in identifying suppliers for these will be greatly appreciated.
