Predictika · Rack server configuration: processors, memory and GPU cards

An AI sales agent's PRIMERGY RX2540 M7 server configuration, checked before it goes out

An AI sales agent prepares a configuration for a two-socket rack server: processors, memory modules, GPU cards and power supplies. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public configuration rules and returns a verdict, every reason and the figures it computed.

Scope: PRIMERGY RX2540 M7 configurations: processors, memory mode and modules, GPU cards, mounting kits and power supplies. See everything this validator covers

This validator models configurations of one server line, the PRIMERGY RX2540 M7, not just the scenarios shown below.

  • Processors — 1 or 2 processors; four processors (Xeon Bronze 3508U, Gold 5512U, Platinum 8558U, Platinum 8581V) cannot be used with a second processor, and a second processor needs an additional cooler kit.
  • Memory — 16 module slots per processor; Normal Mode takes 1, 2, 4, 6, 8, 12 or 16 modules per processor, Mirroring Mode takes 8 or 16; RDIMM x4, RDIMM x8 and 3DS modules cannot be mixed; module sizes from 16 GB to 256 GB; the stated memory total is compared with the order.
  • GPU cards and power — at most 4 NVIDIA A2 or L4 cards, at most 2 L40S cards, 1 GPU mounting kit, cards that need a second processor (L40, H100 NVL, H100 80GB, RTX A6000, RTX A4500), and 1 or 2 power supply units.

Any RX2540 M7 configuration that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the public guide has none, so this validator produces no price build-up or line-item quote), chassis and drive-bay choices, storage controllers, risers, network cards, liquid-cooled variants, other PRIMERGY models and regional terms.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A second processor that some processors cannot takeOnly with care
A product rule on the processor choice that interacts with the processor count; it works, but each new processor model is another rule to maintain.		Processor model, processor count and cooler kit are in one request and checked together.
Memory module counts that depend on the memory modeOnly with care
The allowed counts differ by mode (1, 2, 4, 6, 8, 12 or 16 versus 8 or 16), so a rule per mode is needed and the two must stay in step with the chosen mode.		The mode and the module count arrive together and the count is checked against the chosen mode on every call.
Card limits that depend on other choicesOnly with workarounds
Card limits per type and the need for a second processor span several lines, so they need cross-line rules that interact with the rest.		Every choice is in one request, so a conflict is found whichever order the choices arrive in.
Stated memory total that must match the orderOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed total, but someone has to write and maintain that comparison.		The stated figure travels with the order and is compared with the computed figure on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a configuration for a two-socket rack server: processors, memory modules, GPU cards and power supplies. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public configuration rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a PRIMERGY RX2540 M7. The configuration states 512 GB of memory in total. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The order has 5 NVIDIA A2 or L4 cards; the limit is 4 per system. The order has 2 GPU cards that need a second processor, such as the L40 and H100 NVL, but the order has fewer than 2 processors. The order has 2 GPU mounting kits (PYBTKMX0K); the limit is 1 per system.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a second processor that some processors cannot take, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the processors to 2, the second-processor cooler kits to 1, the NVIDIA A2 or L4 cards to 4, the GPU mounting kits to 1, the power supply units to 2 and the stated memory total to 1,024 GB.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
