Company AI Server
A proper GPU server: 4-8 cards, redundant power, BMC management and fast networking, for a company that has outgrown a workstation.
Roughly ~80B params in fp16, ~160B in 8-bit, or ~295B in 4-bit quantization.

- · Four L40S: 192 GB of VRAM, passively cooled by the chassis fan wall - the density and airflow model a real server is built around.
- · EPYC 9354 gives 128 PCIe 5.0 lanes and 12 memory channels: the whole server has bandwidth, not just the GPUs.
- · 512 GB of ECC memory keeps large models and their KV cache addressable outside VRAM when needed.
- · Redundant CRPS power and a BMC (IPMI / Redfish) mean remote power-cycling, health telemetry, and a hot-swap PSU - the difference between a server and a big PC.
- · A 100 GbE NIC is there for the day this becomes node one of a cluster.
- + 192 GB VRAM, serviceable and monitored
- + Redundant power, remote management
- + Headroom to 8 GPUs in the same chassis
- − Loud - a dedicated room with cooling is not optional
- − Still one node: cluster-grade availability needs at least two
- − L40S has no NVLink - large-model training wants SXM parts
Four A6000s: same 192 GB, blower-cooled, roughly half the GPU cost.
Four RTX 6000 Ada: 192 GB with the best single-card throughput short of datacenter SXM.

- · High-availability needs usually keep some cloud capacity in reserve even when owning makes sense - hybrid covers both.
- · Over 36 months, owning saves roughly $26897 versus the cloud equivalent.
