This is about some comments from Oracle EVP John Fowler. He indicates that disk
is dying. He envisions it being replace by flash RAM. And not in our current
mode of being an external I/O device, but actually being on the data bus of the
CPU. So all active data will be in non-volatile, directly addressable, server
memory. Backup will be on high speed (1,380 Tb/hour ==~ 383 Mb/second) tape.
Not related to this directly was talk about a Sparc processor with 128 cores
and 16,384 threads.
Yes, he said. So what?
Case
a) it will happen. Journalists will cite him (mostly in the airplane
magazines).
b) it won't happen. Dot. Nothing more. Nobody will remember his words.
The world is full of forecast, predictions and prophecies. People
remember only few of them: the most accurate and the most funny because
of its inaccuracy (Watson Sr: 5 computers, Gates: 640kB is enough).
Regarding to the disks: indeed we observe first time when silicon "RAM"
succesfully replaces disks in some areas. Is it beginning of revolution
like CRT->LCD switch? Maybe, we will see. What's sure (?) the changes in
computer architecture will come much later, after "HDD philosophy" will
become totally obsolete. It would require many changes in both HW and SW.
