The cost of renting IBM servers for SAP workloads (like SAP S/4HANA or SAP HANA) is not a fixed number—it depends heavily on configuration, memory size, and whether you choose on-prem, cloud (IBM Power Virtual Server), or managed SAP (RISE with SAP).

Here’s a realistic breakdown based on IBM pricing models and industry ranges:

💰 1. IBM server rental cost model (SAP workloads)

IBM typically charges in two main components:

🔹 A. Compute (CPU core-hour)

• Charged per dedicated Power core per hour
• SAP HANA workloads are usually higher-priced than standard Linux workloads

👉 Typical range:

• $0.80 to $3.50 per core/hour (depends on Power system type & profile)

🔹 B. Memory (GB-hour)

• SAP HANA is memory-intensive, so RAM is billed separately

👉 Typical range:

• $0.01 to $0.05 per GB/hour

📊 2. Monthly cost examples (realistic SAP sizing)

🟢 Small SAP system (Dev/Test)

Example:

• 4–8 cores
• 64–128 GB RAM

💰 Estimated monthly cost:

• $800 – $3,000/month (₹65,000 – ₹2.5 lakh approx.)

🟡 Medium SAP system (Business production)

Example:

• 16–32 cores
• 256–512 GB RAM

💰 Estimated monthly cost:

• $3,000 – $12,000/month (₹2.5 lakh – ₹10 lakh)

🔴 Large SAP HANA production system

Example:

• 64+ cores
• 1 TB – 8 TB RAM (typical enterprise SAP HANA)

💰 Estimated monthly cost:

• $15,000 – $60,000+ / month
  (₹12 lakh – ₹50+ lakh+)

☁️ 3. IBM Power Virtual Server vs dedicated hardware

⚙️ 4. What makes SAP on IBM expensive?

• 🧠 Huge RAM requirements (SAP HANA is memory-first)
• 🧾 SAP licensing (often bigger cost than hardware)
• 🔐 High availability + enterprise SLAs
• ⚙️ Dedicated CPU cores (no oversubscription like cheap cloud VMs)
• 🏗️ Certified SAP hardware requirements

📌 5. Simple real-world rule of thumb

For SAP on IBM Power:

💡 Monthly cost ≈ $40–$120 per GB of RAM + CPU charges

So:

• 256 GB system → ~$2,500–$8,000/month
• 1 TB system → ~$8,000–$25,000/month+

🧾 Bottom line

• Small SAP dev systems: under $3K/month
• Medium production: $3K–$12K/month
• Large enterprise SAP HANA: $15K–$60K+/month
