z14 and zBX

[R.S.]

I haven't seen any information regarding zBX for z14 machine.
Does it mean IBM (quietly) closed the idea of zBX?

zBX was withdrawn from marketing on March 31, 2017. However, if you have a zBX Model 004 and the z14 has the Ensemble feature code 0025, the zBX can be in the same Ensemble as the z14. Remember, the zBX Model 004 is a standalone node and not 'tied' to a CPC e.g. z13/z13s/z14

I believe zBX suffered from being too little, too late - if it had been
released a decade earlier, it might have been a killer. It was also a fairly
narrow solution in terms of what was available to run on it.



I also understand that it was dependent on specific hardware (blades), which
IBM did not manufacture. I heard (unsubstantiated) that when those blades
ended production, IBM they bought up a ton as spares; when zBX then failed
to take off, they were stuck with the inventory, and thus had dug themselves
a big hole from which the zBX could not escape.



Perhaps one of the ex-IBMers who lurk here can confirm or deny-I'm sure no
current IBMer would want to risk his/her job thusly!



.phsiii (who is sad, because he loved the idea of the zBX!)

IMHO it was a mistake from the begining.
Whenever I asked the question: "what is the difference between zBX and
regular 19" rack with blade servers" I heard about Ensemble, OSX, OSM,
etc. Customers do not need ensembles. From customer point of view zBX
is just rack with servers, but less flexible, vendor locked and more
expensive. Even IBM did not use zBX for its appliance like IDAA.

If this is all you understood about the product, either you were misinformed or it wasn't explained properly to you. As the zBX is now history, its pointless trying to 'sell' its real benefits/advantages. As regards the IDAA, it was a introduced before the zBX and was actually a variant of it!

The above is some simplification, however I heard A LOT OF zBX, saw a
lot of presentations, and IBMers never ever convinced me the zBX is
something more than LAN-attached rack.
Regarding IDAA, at the time zBX was first introduced (z196), there was
ISAO - IBM Smart Analytics Optimizer. Then they changed name (only a
name?), then IDAA arrived.
And not, IDAA is NOT an zBX example! It does not use any of zBX specific
features. It's more like Dell/HP/AnyVendor LAN-attached appliance.

zBX was a mistake. Every company makes them.

for at least past ten years, large public cloud operators have been
claiming that they assemble their own systems at 1/3rd the price of
brand name server vendors. their large megadatacenters having hundreds
of thousands of these system blades. Within past couple years, system
processor chip makers have been saying that they ship over half their
chips to these large megadatacenters ... significantly changing large
datacenter model (and possibly contributing to IBM selling off its
server business). Each one of these blades having upwards of ten times
the processing power of max. configured z14 ... and a single
megadatacenter will have several hundred thousand of these blades, and
there are large scores of these megadatacenters around the world.

more than 30 years ago

early 1979, I got con'ed into doing 4341 benchmarks (on engineering
4341, they hadn't started shipping yet) for LLNL that was looking at
getting 70 4341s for computer farm (sort of leading edge of cluster
supercomputers).

starting in the early 80s, we were working with director of NSF on
inter-connecting the NSF supercomputer centerrs. We were suppose to get
$20M ... but then congres cuts the budget and things drag on for
sometime while we continue to work with the director. I had also done a
proposal to do racks of processor chips ... racks with arbitrary mix of
cards with arbitrary mix of 370 & 801/risc CMOS chips. This is old email
having scheduled meeting with director of NSF but also a week of
meetings at research on racks full of arbitrary mix 370 & 801/risc chips
(I had to get somebody to fill in for me at the NSF meetings)
http://www.garlic.com/~lynn/2007d.html#email850315

I had project I called HSDT that had T1 and faster speed links ...
including connectivity to IBM mainframes using non-IBM controllers.

there is not a lot of interest within IBM about including 370 chips in
cluster racks ... so eventually it is only 801/risc power chips. We are

scaleup. past reference JAN1992 meeting in Oracle CEO's office about

As I said, this is not the time for zBX education. Its history.

Re: Regarding IDAA, at the time zBX was first introduced (z196), there was
ISAO - IBM Smart Analytics Optimizer. Then they changed name (only a
name?), then IDAA arrived.
And not, IDAA is NOT an zBX example! It does not use any of zBX specific
features. It's more like Dell/HP/AnyVendor LAN-attached appliance.

ISAO did use 'similar' H/W and connectivity as the zBX with System X Blades. IDAA was the follow-on solution using PureData System for Analytics
(Netezza Technology). Both SOLUTIONs were (ISAO)/are (IDAA) tightly integrated with System z, z/OS and deep integration with DB2 providing transparency to all applications. IDAA is not just a LAN-attached appliance.

IDAA is just LAN-attached appliance. Yes, the solutions is great and
tightly integrated with DB2, but the HW platform is just LAN-connected.
No management via HMC, no OSM chpids, no OSX chpids.
And this is another proof there can be very useful solutions without
anything which is specific to zBX.
BTW: IDAA hardware is not just bunch of x86 blades.

BTW2: microcode and service management of IDAA sucks very much.

IMHO it was a mistake from the begining.
Whenever I asked the question: "what is the difference between zBX and

regular 19" rack with blade servers" I heard about Ensemble, OSX, OSM, etc.
Customers do not need ensembles. From customer point of view zBX is just
rack with servers, but less flexible, vendor locked and more expensive. Even
IBM did not use zBX for its appliance like IDAA.



The disadvantages you cite are real, for sure, and may have been sufficient
to kill the concept right there. But the *idea* was that high-impact
processing could be easily/seamlessly offloaded. The "too late" part is that
the folks who needed to do that had already bitten the bullet and done so.
Fifteen years ago, not so much.



I also suspect that fifteen years ago, the gaps-physical, political,
theological-between z and distributed folks were greater, such that it would
have been easier for the z folks to justify keeping the data away from those
squatty-box weenies that they didn't trust. By now, most z folks are
resigned to their interdependence on those same squatty-box weenies.

The IBM 360 mainframe was designed to process data from other machines
and distribute to them. Punch cards, Printers, card to tape machines,
RJE machines, 3270 screens / printers. The PC with 3270 emulator (and
now browser) replaced an I/O device, but also became a storage / user
processing devices (spreadsheets, etc).

Now I understand your point. Yes, obviously you're right with the
offload and IDAA is excellent example of such offload, but it does not
exploit any of zBX-specific features. Some other offload examples could
be zEDC or even CryptoExpress. It's a kind of "internal offload" - the
offload is being done. but the appliance reside inside the CEC as a card.

BTW: It's a pity the IDAA is not under HMC management. It would
significantly simplify microcode management and possibly remote access
of service folks. Current procedures for that are horrible.
