Should we be calling IBM Big Green?
So here we are back to 40 years ago when IBM’s revenue mainly came from renting computer power to customers who connected their thousands of 5250 or 3270 terminals to mainframes using unbelievably slow modems that were each the size of a small desktop computer.
At the time, I was a Computer Science student and spent some time as an intern at IBM France. I participated in installing what was then the largest mainframe in France: an IBM 370/168 (it later became the zSeries) that had a whopping 512 Megabytes of RAM (yes kids…512Mb…stop laughing please…) and stacks of 3330 removable hard disks that could each store 200Mb of data on 8 platters (stop LOL).
Guess what: IBM has just announced they are reviving their System z strategy with the zEnterprise 196.And nobody is laughing this time.
What has changed?: it has 3 Terabytes of RAM,up to 96 processors, reams of blades and can manage loads of P and X servers. IBM says 30% of all servers are running Linux, and that the zEnterprise should soon support Windows clients. 40 years ago, the internal bus of an average computer probably ran slower than today’s high speed ADSL, SDSL etc…(why have you stopped laughing?)
Although total cost of acquisition (TCA) will be higher then for servers, TCO is lower within 3 years. Not to speak of the green side of things, these machines are much more energy efficient than a pile of servers.
If you still think Cloud Computing is a pie in the sky, think again because IBM certainly want to be at the forefront of the next paradigm shift.
