Jim Gray's Interview on Storage and Database
ACM Queue has a very interesting interview with Jim Gray, head of Microsoft bay area research, a recent Turing award winner, a guru in database and computer systems. Guess who asked questions? David Patterson.
"One thing is a no-brainer. Disks will replace tapes, and disks will have infinite capacity. Period." The problem is not where to store your data, but where to find something to put in your disk. Random disk access will be a huge problem when disk capacity increases dramatically. The fundamental disk access scheme and corresponding data storage scheme might need to be altered. Microsoft is "replacing the file system with object store, and using schematized storage to organize information". Take a peek of that later.
Another interesting point is, as Gray said, every device, disk, NIC, display, whatever will be having a powerful CPU, large RAM, OS, and software. No IDE or scsi or PCI bus, just IP over everything.
