2 licenses for the os with 8 processors currently. Sitting at 500 interactive sessions right now. I've seen it as high as 600 recently. We just added a client and we are creating 100 workstation id's for them - all with an A & B session. I don't expect we will ever get all 200 active at the same time, but probably 75-100 active during the day in the next few months.
I haven't dug into adding an ASP, but it is on my todo list before we do this migration.

Subject: RE: New system configuration
I currently have a very similar scenario, no Vios, combination of SSD and 10kspinny on P7, we are ordering a P9 S924.
The 10kspinny are slow, not 100% busy.
How many i5/OS licenses do you have?
Lots of 5250 users - how many? We have 1000+.
My plan is to have Production LPAR own all the hardware, (DASD, Ethernet).
100% SSD.
Production LPAR will host all other LPARs.
Using a new HMC, CPU, Memory, DASD and Ethernet will be virtualized.
For DSAD - 5 NSD with 6 NWS of 500gb each. 30 NWS total.
Create more if needed.

This document contains information on configuring Ethernet Link Aggregation.
Client Ethernet LPARS will be bridged.
https://www-01.ibm.com/support/docview.wss?uid=nas8N1011193
For Tape backup, each LPAR does have its own FC adapter connected to our 3573 LTO7 tape library.
If you can't justify 100%SDD, consider at least having LIC and OS on SSD in the system ASP.
Create ASP02 for all your data .
I currently have a 2 ASP setup on R&D.

Subject: New system configuration
It is finally time to retire our old Power 6 box and get some shiny new hardware. Over the years all the experienced techs here have moved on, and we currently have one person who is basically a sysopr, changing tapes and fixing passwords etc. We have one other programmer besides me, but I'm basically the only person with any real experience dealing with the low level layout and config of the system, so I get to recommend a layout and specs for a new box. I'm here asking you to shoot holes in my thinking so I can avoid as many mistakes as possible.
Current setup - Really old HMC running V7R7.9.0 on a 7042CR4. 4 lpars. Vios, Production (IBM i), Development (IBM i), Linux - I threw this up just to walk through getting Ubuntu running on the box based on a discussion on this list. The Linux partition is powered down and not used. All spinny disks. Production has it's own controller with disks attached, vios serves up disks for development and the Linux partition.
We have lots of 5250 users. We built a web based front end, but hardly anyone uses it. Full backup of production once a week with an IPL following, and full backups of dev three times a week with an IPL following.
Disk throughput on dev and linux box are slow. Dev shows 100% busy all the time in wrkdsksts. I want to avoid that this time. Probably still spinny disks as I don't see management wanting to change disks every three years. When we configured this box we were thinking we wanted to run linux on the box to handle our web front end as well as some other web products we have. That didn't pan out. Right now all Vios is doing is serving ethernet to all the partions, disk to dev and linux, and a tape drive that we move between production and dev, but that lives on dev 99% of the time.
I'm thinking we look at a S922 or S924 in the P10 group. Get us out of the P20 group but still have a significant performance improvement. A modern HMC (did they discontinue the VMWare HMC?). Host development as IBM i on IBM i on the production environment. I am ok with dev going down at the same time as production.
My questions:
Is IBM i on IBM i going to be fast enough for the dev lpar?
Can I really get rid of Vios?
Is there a better setup?
