Re: First time buying System i5

   Yes, I know you stated that he could start with 3 and then add additional
   drives  I was just emphasizing the fact that you eluded to of getting more
   disk drives.   We said the same thing, I was just emphasizing that running
   under 3 if you do a lot of I/Os on your machine (or partition) would be
   unpleasant.

 Pete,

 Read my post again.  I didn't tell him to go with a 3 drive RAID set, I
 said go with 3 standalone drives, one for each LPAR.  Then simply add
 more drives purchased used.

    You will be very unhappy with a 3 disk Raid-5 set.  Spend
 the extra money
    and go with 4 disk drives.

  Aaron,

  Couple of things.  For 3 LPARs you only really need 3 disk
 drives as far
  as IBM is concerned, as you don't have to use mirroring or RAID.

  You might then be able to pick up some additional used drives.

  Another option, at my last employer, we purchased a 270 without any
  drives and then filled it with FAST technology drives from BCC, (now
  called eStorage: http://www.estorageinc.com/index.htm )

  Based on comments from this group I called back IBM and
  worked through what
  I think I will need for a configuration.  One area that I was
  surprised at,
  that is going to cost a boat load of money more, is that each
  LPAR needs to
  have it's own exclusive HD's.  So for a 3 LPAR machine I would need a
  minimum of 9 35GB HD's (optimally 12 so each LPAR could have
  4 each).  That
  means for HD's alone the cost is $14,388 (ouch).  Note though
  that memory
  can be shared across LPARS.
 
  So I may be back to looking at a single LPAR machine unless I
  can find a
  steal of a deal for some 4326 HD's.
 
  Question for the minds: If I go with a machine without
  separate LPARs to
  start with, how much "work" would it be on my end to upgrade
  to an HMC with
  multiple LPAR's in the future?

  Hi Everyone,
 
  For a variety of details I wont dive into, I am now tasked with
  purchasing/leasing my first System i5.  I am actually quite
  excited because
  it is the same feeling I get when I buy a new PC, except this
  time I have
  next to zero knowledge on what I need to tell the friendly
  guy on the other
  end of the phone.  I am coming at this from an Partnerworld
  ISV standpoint
  where they give what seems to be pretty darned good deals for
  leasing or
  buying (i.e. 1% of list price per month or 50% off list
  price). Note that
  this is strictly going to be used for development and does
  not need to be
  HA.
 
  Here's what I need to be able to do on the machine:
  1. Develop RPGILE/CLLE/CLE/SQL code (need to be able to
  compile at V5R1)
  2. QShell environment.
  3. Ability to run Java natively AND in a servlet container
  (Tomcat is my app
  server of choice)
  4. Ability to have more than one LPAR (rep tells me I need an HMC to
  accomplish this. The HMC is some sort of Linux appliance that
  gives you
  control over your different LPARS)
  5. Backup code and files (talking less than 1 or 2GB). Do I
 need addtl
  hardware for this or can I back to a network device?
  6. Less than 5 profiles on 5250 at any give time.
  7. DB2 and Query and SQL capabilities
  8. WDSC and PDM (I already have WDSC 6.0)
  9. Apache and SSL capabilities
 
  My retail price range is $10k to $15k which from what I can
  tell will get me
  a solid entry level machine.
 
  Based on the "Quick Pricer PDF" emailed to me, here is what I
  THINK I need,
  but I am lost as to if I have everything covered.
 
  Model/Server Feature SW Tier: 520-0975 P05
  CPW: 600/30 cpw
  Edition Name: Value
  Processor Speed: 1.9 Ghz Power 5+ includes L3 cache on
  1200/60 cpw version
  Processor Feature: 8325
  Edition Featue and Price: 7350 $8,200
  ESA 24x7: $110
 
  Some things I don't understand or need clarification on:
  1. What are "feature codes"? (i.e. 8325, 7350, etc).  For
 instance, it
  appears as though feature 7350 is a package deal of some sort.
  2. From what I understand ESA gives me 24x7 access to
 support vs. just
  within business hours (seems like a good deal for only $110 more).
  3. What is "5250 CPW 30"?  Is that how much processing power
  is given to
  green screens?
  4. When they say "Disk Drive" on this page:
  http://tinyurl.com/pbpxa, what
  are they referring to? A harddrive? A backup drive of some sort?
  5. Do I need a "Twinax Adapater"?  Is that if I want to
 connect an old
  school console directly to the machine?
  6. What's the difference between the "Comm Adapter" and
  "Ethernet Lan" on
  this page: http://tinyurl.com/pbpxa
  7. Is 600/30 cpw enough horsepower to run a machine with less than 5
  developers on it at a given time?
  8. Is 1GB of memory enough to do general RPG development with
  some small
  Tomcat/Java and native Java mixed in there?
 
  Thanks to anyone that can help this lowly programmer buy his
  first iSeries
  :-)
