By contrast, the Ramac
virtual arrays already feature this capability.
So you could keep records of inventory, customers, accounts receivable, and so forth--and it was called the random access machine, RAMAC. And then the spin-masters got hold of it and changed it to the Random Access Method of Accounting Control, and that became the acronym for RAMAC.
When they had already built the development models, I went to see the 305-a RAMAC. I looked at the signals coming off the file and they looked very erratic.
In the same way, says StorageTek, Shark's Concurrent Copy feature, already out on System 390 drives, was upgraded on the Ramac virtual architecture to include integration with Snapshot, but IBM has now had to revert back to its original version on the Shark.
Meanwhile, StorageTek believes that IBM on Monday will quietly upgrade its existing Ramac systems, still sourced from StorageTek, as an option for those who aren't ready to move over to the new - but in StorageTek's eyes the more traditional - Shark architecture.
I got assigned to the RAMAC project but I didn't do anything in customer engineering.
CTR: That's good for the beginnings of RAMAC. What do you think are the significant mile-stones after that and up until today in the disk drive industry?
1997 The capacity of a single disk from Seagate reaches 47GB, 9,400 times greater than the original RAMAC
IBM has been selling the RAMAC
since 1994 and has been purchasing it on an OEM basis from StorageTek.
IBM added a new peer- to-peer copy feature to its model 9393-T82 RAMAC
Virtual Array (RVA) "Turbo" arrays for mainframes, a StorageTek product formerly known as Iceberg that IBM resells under the RAMAC
Beginning with a punched card and soon followed by the first magnetic tape drive, the IBM 726 in 1952, and the first disk drive, the IBM Ramac
350 in 1956, the storage industry and its hierarchy was born.
A "Step Up" campaign offered expansion of capabilities and assumption of IBM warranties and service agreements to users of IBM RAMAC
Virtual Array and StorageTek Shared Virtual Array (9393) disk systems.
