Sizing Cisco UCS for VMware and AI Inference in Singapore
Last updated: October 2026
Sizing Cisco UCS starts with the workload, not the server model. For VMware, the main drivers are memory and CPU cores. For AI inference, GPU memory decides which models you can run. Network, storage, power and licences complete the design.
Megatron Technology supplies and deploys Cisco UCS in Singapore. This guide lists the questions we ask before we size a server.
What drives sizing Cisco UCS for VMware?
Memory. Add the memory of all virtual machines, then add headroom for growth and host failure.
CPU cores. Count the vCPUs you need. Check how your hypervisor licence counts cores.
Storage. Decide between local disks and shared storage.
Failure tolerance. Plan at least one spare host (N+1).
What drives sizing for AI inference?
GPU memory. The model and its context must fit in GPU memory.
Concurrent users. More users need more GPU capacity or more GPUs.
Power and cooling. GPU servers draw much more power than standard servers. Check your rack and your room.
Network. Inference servers need fast links to storage and users.
Which UCS form factor suits which job?
UCS Models and GPU options may change. Confirm with partner when sizing.
What should you send us?
Current VM list with vCPU and memory.
Growth plan for 3–5 years.
AI use case, model size and user count.
Rack space, power and cooling limits.
Hypervisor and licence model.

Frequently asked questions
What is the first step in sizing Cisco UCS?
Collect the workload: VM memory and vCPU for VMware, and model size and users for AI.
Do we need GPUs for AI inference?
For most language models, yes. GPU memory decides which models you can run.
Can one UCS cluster run VMware and AI?
Yes, if the design includes GPU hosts and enough power. Many sites keep them as separate host groups.
