6446.7and here is the marketing stuff....SUBSYS::VIDIOT::PATENAUDEAsk your boss for ARRAY's...Thu Mar 06 1997 09:4376
MAYNARD, Mass., March 3, 1997 -- Digital Equipment Corporation today 
is introducing a new Nine-GB magnetic disk drive for its high-
availability StorageWorks RAID Array subsystems, lowering the cost 
of storage for customers with data-intensive applications. Digital's 
StorageWorks subsystems are now the most cost-effective storage 
solutions on the market for large-scale computing projects such as 
data warehousing or mail and messaging in centralized or distributed 
mixed-vendor environments. 

     Configurations are available for 45 cents per megabyte at list 
price -- the lowest cost in the market today. Using the new Nine-GB 
drives, customers can configure up to a terabyte of storage in a 
single StorageWorks cabinet that occupies only 7.5 square feet of 
floorspace. StorageWorks subsystems with the new drives offer more 
capacity per square foot than comparable solutions from EMC, and 
support multivendor hardware platforms, unlike solutions from Sun 
Microsystems. 

     "With database sizes growing at phenomenal rates, customers are 
looking for solutions with hundreds of gigabytes to multiple 
terabytes of storage, and that can be costly," said Dave Coombs, 
vice president of Digital's Worldwide Storage Marketing group. "This 
is especially true for data warehouse and mail and messaging 
applications which are often distributed across an enterprise. 
Digital is responding by offering customers multivendor storage 
solutions with the capacity and functionality they need, at prices 
they can afford." 

     Dave Richardson, business development manager at Bershire 
Computer, a VAR that specializes in high-end data management 
solutions, said, "The addition of the Nine-GB disk drives to the 
Digital StorageWorks product line more than doubles the capacity of 
our storage solutions while maintaining the same footprint. It 
enables us to meet our customers' growing storage requirements and 
offer solutions at a lower cost per megabyte." 

     Based on a modular architecture, the StorageWorks family 
includes RAID Array subsystems that span the desktop to the data 
center, comprehensive storage management software, and a range of 
industry-leading devices. 

     In a recent survey conducted by Computerworld, a weekly 
newspaper for information systems managers, customers gave Digital's 
StorageWorks products the highest ratings versus Compaq, Sun, IBM, 
and Hewlett-Packard in terms of overall satisfaction, compatibility 
with server hardware, and price. 

Pricing and Availability

     Digital's Nine-GB drive in a 3.5" form factor with magneto-
resistive heads is priced at $3,349. It is compatible with previous 
generations of Digital's magnetic disks and is available now.

     For more information about Digital's complete line of storage 
hardware and software products, call 1-800-STORWORK (1-800-786-7967) 
or visit http://www.storage.digital.com on the World Wide Web. 

     Digital Equipment Corporation is a world leader in open client/
server solutions from personal computing to integrated worldwide 
information systems.  Digital's scalable Intel and Alpha platforms, 
storage, networking, software and services, together with industry-
focused solutions from business partners, help organizations compete

6446.9How many can you put in a BA-356?SLOAN::HOMFri Mar 07 1997 14:317
For some reason, there's no mention on the number
supported in a BA-356 shelf. Everyone is assuming
that with a single 150 W supply, 7 9GB drives can be
used. Is that correct?

    Gim,
    
    In a word....  yes.
    
    7 DS-RZ40-VA are supported by 1 BA35X-HF (150W P/S).  However if your
    personality card consumes more power than the BA35X-MH, you will be 
    limited to 6 drives with the BA35X-HF.  (Sorry, can say anymore at 
    this time....)

It's only supported behind HS* controllers, NOT as a bare drive
in a bare BA356 cabinet.

Is that true ?!?  Just because a drive is in a SW500/800 cabinet
doesn't mean it's behind an HS* controller !!!  We configure some large 
Oracle systems with lots of disks mounted in a SW800 cabinet, but directly
connected to the host via KZPSAs, no HSZxx involved !!  Nowhere in this
annoncment did I see a restriction that says the drive HAS to be behind an 
HS* controller, only that it is not supported in a BA356-KC pedestal.

Please check and confirm one way or the other ...

re .13:

If you don't use an HS* then, from a KZPSA, you'll need a DWZZ*.  Otherwise you
could get into a backplane RAID controller or just the KZPAA.

I took the combination of the above to mean HS* support only.
I'd love to have someone correct me and tell me my assumption
is wrong.  There sure isn't anything stopping direct connect
disks from working (assuming a correct version of the O/S).

    Is this a "marketing" restriction, in that the company only wants to
    sell the disk into the high-end/high-margin opportunities first given
    the limited supply?
    
    Or is it a timing issue, to get the product to market as quickly as
    possible only so many configurations have been tested with the others
    to follow?
    
    It does not seem likely that the drive would *not* work on the other
    controllers.
    
    Any comments appreciated,

>    Or is it a timing issue...

Based on my understanding, it is (of all things) an FCC issue.

The RZ40 drive is based on newer technology, has higher internal clock and data
frequencies, and simply radiates more than the older drives. When you put a
bunch of them into one of our shelves, the shelf exceeds the FCC Class B
emissions limits. We do not rate our drives for FCC classes, we rate our
shelves, so this drive makes our shelves "illegal" for FCC Class B.

FCC Class B is the FCC class for equipment suitable for home use. FCC Class A
is the FCC class for equipment suitable for "industrial" use - in offices,
factories, etc. All of the enclosures that our StorageWorks shelves fit into
are FCC Class A enclosures, except one - the BA356-KC. So, we cannot claim that
this drive is supported in the BA356-KC because that would put us in violation
of the FCC certification for this shelf. And, we cannot simply "reclassify" the
BA356-KC as FCC Class A because, well, the FCC rules are byzantine and do not
allow anything so simple.

So - will the drive work in the BA356-KC? Yes, it will.

Can users put the drive in a BA356-KC in "industrial" environments without
creating excessive RF emissions? Yes, they can, but we can't officially claim
support for the drive in this configuration.

Can those people using the BA356-KC at home install the RZ40? Well, the FCC
rules are ultimately based on something real, and so these users might notice
an increased level of snow on their TV sets - if the BA356-KC is sitting on
top of the TV...

We are working on an improved BA356-KC which will allow these drives and be
certifiable as FCC Class B. It will have a different part number.
6446.19more on RZ40 FCCHOUNDD::BASSETTBillFri Mar 14 1997 17:2133
    re: .18
    
    Actually - the "class B compliant with the new family of drives"
    BA356-KC will remain as the BA356-KC - but with a new rev (B01 vs. 
    A01).  What Richie states is very true, the rules for FCC and CE Mark 
    are incredibly difficult to understand - and frequently contradictory!
    
    The DS-RZ40-VA will ALWAYS be class A, since that's what it was
    qualified as.  To be Class B - it would require a new part number.
    Since we want to keep the BA356-KC as class B and NOT introduce a new 
    BA356-Kx variation AND meet the shipping date for the DS-RZ40-VA, it 
    was decided to forgo meeting Class B for the DS-RZ40-VA.  Since the
    pedestal version of the BA356 was the only BA356 used in the class B 
    environment, RZ40's are "banned" from the pedestal.  (Remember... the 
    RZ40 is the NARROW 9Gb....)
    
    If the RZ40 could have waited for the shelf and SBB FCC mods, the RZ40 
    would have been class B.  The remaining drives of the new family are 
    planned to ship later - so will meet class B.
    
    NOTE: when we say FCC testing or FCC issues, we are referring to
    compliance to DECstd 103.  DECstd 103 incorporates EMI/RFI requirements
    from all over the world.  In the US it's FCC, in Europe it's CE, 
    Australia is C-Tick, in Japan VCCI....  Then there are the "CISPR"
    limits which I believe combine all of the above into one set of test 
    limits.  [A product might pass CE, but fail FCC (or vice versa) since
    CE limits are different than FCC.  Europe and the US use different
    frequency ranges for radio and TV.]  I can't remember if we are using
    CISPR now or are simply testing to combined limits.
    
    It's been busy the last few months getting these drives to pass....

6446.20OTOOA::JPONDTue Mar 25 1997 13:4311
    Another query....
    
    Looking at the press release for the RZ40 drive, it says that supported
    OS's include something called "Windows NT 3.51-1".
    
    What actually is meant by this, as it definitely does not refer to any
    version of Windows NT that I am familiar with  8-)
    
    Thanks in advance,

6446.21How about the RA310?LEXSS1::LYONSWed Mar 26 1997 08:147
    Is the RZ40 supported in a RA310?
    
    The enclosure is not a BA356-KC nor a SWXXX.
    The controller is a HSZ20 with HSOF SW?

6446.22Problems Installing a FR-CFCBA-CA on a 2100SVCVAX::GAMBARDELLAGamby GumbaThu Apr 03 1997 12:3222
A customer called me because they had trouble installing a FR-CFCBA-CA (RZ40)
on a 2100.  They are running Windows NT v3.51 with sp5. The drive is being
installed in the internal BA35x box and is replacing an RZ28-VW.  The drives
are running off the embedded SCSI controller.  Basically what the customer 
tells me they did was remove the RZ28-VW in position 4 (SCSI ID 5) and 
install the FR-CFCBA-CA in its place.  They then had SCSI bus addressing 
problems.  It looked like there were 2 drives at SCSI ID 4.  The new drive
did not come up as SCSI ID 5, but rather as 4 and duplicated another drives
ID.  They did not spend any time troubleshooting this and put back in the 
RZ28-VW.


I did not find much info on these new drives, so I have some questions.

o Are they supported off the embedded SCSI controller on the 2100?
o Are they supported under Windows NT V3.51?
o The customer tells me that there are 2 switches on the back of the drives.
  What are they used for?

Thanks for any help/pointers.

6446.23I don't think a FR-CFCBA-CA is an RZ40OTOOA::LAVIGNEThu Apr 03 1997 13:239
    First of all an FR-anything is a PCBU drive which is not StorageWorks
    and is not tested nor supported in anything but a PCBU product.  What
    should have been ordered is a DS-RZ40-xx.  This is a fully supported
    product on Digital Alpha, NT/Unix/VMS/SUN/HP/everything else.  If you
    order PCBU drives don't plan on it working or being supported on anything
    but a PCBU product.  If you want supported and tested product buy
    StorageWorks.

.-1 You're right I called the customer back today and they did try to save a 
few bucks by not buying the Storageworks certified version of the drive.  Can 
I tell them that an RZ40 is supported in their configuration?  It sounds like 
it is, but I could not find much info on these drives.  I just want to make 
sure before I tell the customer to order one.

Again they want to install an RZ40 off the internal SCSI bus on a 2100 running 
Windows NT V3.51 sp5.


Thanks

6446.25Check the SOC.SUBSYS::VIDIOT::PATENAUDEAsk your boss for ARRAY's...Fri Apr 04 1997 14:4014
The Systems And Options catalog should list what drives are usable on the 2100.
By internal you mean the internal StorageWorks shelf? If so the your looking for
a DS-RZ40-VA.

Another point;

>Storageworks certified version of the drive

It is not that the FR drive was not certified, it's totally different. It is not
an RZ40, it is the same base hardware as a RZ40, but different inquiry data,
geometry, specs, firmware, mode pages, etc...

    I was just trying to keep it simple, but you are right the FR stuff is
    completely different.  Although most customers think they are the same
    because they look like StorageWorks.  As for being supported on the
    2100.  Probably not officially yet.  They are being supported only on
    the HS controllers until the qual process is finished (they may even
    not go back to the 2100for internal drives).  Keep in mind if you are
    not using these behind Raid controllers and the customer is looking for
    high performance with fewer spindles (to keep costs down) he is
    probably in for a negative surprise.  Two 4.3's would probably be better.

The question in .21 was not answered.  I need to know the answer to this.

                           -< How about the RA310? >-

    Is the RZ40 supported in a RA310?
    
    The enclosure is not a BA356-KC nor a SWXXX.
    The controller is a HSZ20 with HSOF SW?
    
    Thanx-

Looks like it's supported in RA450.

Correct?

The RAID Array 450 is usually (I do not know of any other possibilities)
an SW300 + HSZ50 + platform kit for SUN, HP, IBM, ...
