RE: First time buying System i5

Point #2.8: You need lots of memory to get your machine to perform with

Tomcat and Java. At a minimum 4GB. Better 8GB.

Woa.  I think I will challenge you on this one.  Are thinking about
Websphere Application Server (WAS)?  Note that Tomcat is a much more
lightweight servlet engine (i.e. no EJB support among other things).

Note again that this is purely for development and NOT for production.  If I
was going to be having 50+ concurrent users hitting Tomcat then maybe I
would agree with you, but I am only going to have maybe 2 concurrent users
on this machine using servlet engine at any given time.

Thanks for your feedback Lukas,

Hi,

Your Point #1 doesn't seem that easy to me. The new i5+ only run at
V5R3M5/V5R4M0, and you can't compile back to V5R1 (there's only a *PRV
compiler). Maybe one of the programmers on this list can give you better
hints than I can, but this seems rather major to me.

Point #4: You need an HMC if you want to do i5/OS LPARs. You don't need it
for Linux LPARs.

Point #5: All Express Models come with an SLR60 Tapedrive. You can also
Backup your Data into Savefiles and Transfer them over the Network. The
latter needs some CL scripting, the first needs some CL scripting or BRMS
(5722-BR1).

Point #2.8: You need lots of memory to get your machine to perform with
Tomcat and Java. At a minimum 4GB. Better 8GB.

Subject: First time buying System i5

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
:-)
