Memory v. Storage: What's in a Name? (Was: IBM zEnterprise)

2010-08-03 Thread Timothy Sipples
I don't remember where I read or heard the story, but I think IBM preferred
to use the term storage because memory implied that forgetting is
possible. Therefore, to avoid conveying the impression that IBM computers
could forget precious information -- or at least to suggest that forgetting
was less likely -- storage it was.

Nowadays that worry seems rather quaint. But the story makes sense within
the context of that time.

There are still plenty of people who worry about naming and how to explain
new technical concepts in clear, understandable language. Apple, for
example, just introduced a retina display on their new iPhone 4. That's a
good example of inventing a new term to describe and highlight a
distinctive technical feature. To pick another example, the zEnterprise 196
is the first and only server to feature a Redundant Array of Independent
Memory (RAIM) subsystem. All memory -- er, storage -- on the system is
RAIM-protected. RAIM is close to RAID, and that's intentional (I
assume). A lot of people know what RAID is, and so they can quickly
understand the basics of RAIM from that frame of reference.

HiperDispatch is another example. The System z10's designers came up with
some wonderful new technologies to steer work toward the processors that
are most likely to have relevant data accessible in more proximate caches,
but quite frankly the technical engineering names for those technologies
weren't so wonderful. (I don't remember exactly, but it was yet another
nondescript acronym with an embedded slash.) So after a bit of discussion
the term HiperDispatch was born, and that's a lot easier for everyone to
understand and appreciate.

I think since more than 10 years have passed it's OK to relate another
product naming story publicly. In the run-up to Y2K IBM was working on some
patches and updates to PC-DOS. At the time PC-DOS Version 7 was the latest
version available. My recollection is that the marketing team initially
wanted to call the new product PC-DOS Version 7.01 (Year 2000 Ready) or
something very, very close to that. I thought their proposed name was a bit
-- how do I put it politely -- awful. I suggested PC-DOS 2000. Not
exactly breakthrough thinking, I admit, but sometimes only
outsiders (outside the marketing team in this case) can see the obvious.
Fortunately the marketing folks liked that name, and so it was that PC-DOS
2000 was born. It's hard to say exactly what that naming change meant, but
it was worth at least several million dollars because people could actually
find the darn product and understand what it meant in an instant. In a lot
of sales catalogs and other listings the (Year 2000 Ready) parenthetical
would have been chopped off.

I heard a similar story about BDAM; it allowed random access. Random?
You mean you don't know where it is? So it became direct access, Oh

Which is why so many of us thought of RAM (with the M standing for
Memory), as memory, with disk  tape as Storage.

I don't know why this is considered 'new'.

Ever since I started doing Capacity Planning, in 1981,  it was called 'Storage'.

We called it Real Storage, as opposed to Virtual.

Then it became Central Storage, as opposed to Expanded.

Now, it's Real Storage, again.

(Of course, all my Capacity Courses were taught by IbM, so that's probably 
where I caught the habit of calling Storage)

Actually, core was non-volatile, so you could read your core storage
after a power outage.  Not with the S370 transistors.

The Challenger space shuttle computers had core and the memory was

Hi everyone,

I just got back from IBM’s announcement of the next mainframe.

It’s called the zEnterprise or z196 or 2817.

Up to 80 available CP’s
Between 32GB and 3TB of RAIM.

Lots of other neat stuff.

A while back.  I don't recall exactly when but it's been something like 
five years or longer when discussing real memory...at least, for 
announcements and such.



Is Redundant array of independent memory (RAIM) much different from ECC?


Yes, very different.  It's a RAID-like array for memory.  So if you lose 
enough ECC-based memory the hardware can still recover without 
presenting a machine check.  The HW announcement says:


Major redesign of memory subsystem for improved availability: IBM's most 
robust error correction to date can be found in the memory subsystem. A 
new redundant array of independent memory (RAIM) technology is being 
introduced to provide protection at the dynamic random access memory 
(DRAM), dual inline memory module (DIMM), and memory channel level. 
Three full DRAM failures per rank can be corrected. DIMM level failures, 
including components such as the controller application specific 
integrated circuit (ASIC), the power regulators, the clocks, and the 
board, can be corrected. Memory channel failures such as signal lines, 
control lines, and drivers/receivers on the MCM can be corrected. 
Upstream and downstream data signals can be spared using two spare wires 
on both the upstream and downstream paths. One of these signals can be 
used to spare a clock signal line (one upstream and one downstream). 
Together these improvements are designed to deliver System z's most 
resilient memory subsystem to date.



Are modules hot-pluggable?


Sorry, I don't know.  If I happen to run into one of the HW team, I'll ask.

control lines, and drivers/receivers on the MCM can be corrected.
Upstream and downstream data signals can be spared using two spare wires
on both the upstream and downstream paths. One of these signals can be
used to spare a clock signal line (one upstream and one downstream).
Together these improvements are designed to deliver System z's most
resilient memory subsystem to date.


Are modules hot-pluggable?


Sorry, I don't know. If I happen to run into one of the HW team, I'll ask.


I know, cause I saw it (even swapped):  NO.

You have to remove the book if you want to open the case. That's why the 
memory cannot be hot-pluggable.

However:
a) the book itself can be hot-plugged and unplugged (although I'm aware 
of serious problem caused by such process).
b) the memory can be enabled by microcode - like CP. It's even an option 
for CIU.

IBM zEnterprise 196 mainframe due July 22 • The Register

2010-07-20 Thread McKown, John
http://www.theregister.co.uk/2010/07/19/z196_mainframe_blade_interconnect/

quote

As El Reg already 
reportedhttp://www.theregister.co.uk/2010/07/14/ibm_system_z11_preview/, the 
System z11 machine will sport 96 cores and give about 80 of them over to 
running either z/OS or Linux in a single system image (rated at around 50,000 
aggregate MIPS by our math) or allow them to be carved up into logical 
partitions with somewhere around 1,100 MIPS per core.

I was off last week and may have missed any discussion of this here.
