AI: Compute, storage & environment
In one line AI infrastructure is built around accelerators (GPUs) kept busy by intelligent NICs (SmartNIC / DPU) that offload networking and storage so the expensive GPUs never wait. The components * GPU - the accelerator: massive parallel compute plus high-bandwidth memory (HBM). GPUs connect intra-server by NVLink/NVSwitch (scale-up)
AI: Compute, storage & environment
Requirement / business driver Connect many GPUs so collectives run fast - across two dimensions whose boundary shapes the whole fabric. The two dimensions * Scale-up (inside the node/domain) - NVLink / NVSwitch (and the emerging UALink - an open, vendor-neutral consortium standard; AMD's Infinity Fabric is the proprietary parallel) connect
AI: Compute, storage & environment
Requirement / business driver Feed training data and absorb periodic checkpoints without starving the GPUs or stalling on I/O. Two I/O patterns * Training-data ingestion - sustained, parallel high read throughput to keep GPUs fed. * Checkpointing - periodic, bursty, all-nodes-write-at-once (incast!) saves of model state for fault
AI: Compute, storage & environment
Requirement / business driver AI's power density and energy use are first-order design constraints - the facility's power and cooling envelope can cap how many GPUs you can deploy, and sustainability/cost pressures make efficiency a design driver, not an afterthought. Power density AI racks draw 40-
AI: Compute, storage & environment
In one line AIOps applies ML to the flood of telemetry and logs an AI fabric produces - to detect anomalies, correlate events, and (eventually) auto-remediate - because thousands of GPUs and sub-second telemetry are beyond human monitoring. The three blueprint pieces * Data scrubbing (4.3.a) - clean, normalize, and
AI: Compute, storage & environment
In one line Storage networks are designed around one question - how does the fabric guarantee delivery, and who pays for that guarantee - and each protocol answers it differently: FC builds losslessness into the link layer, FCoE borrows it from Ethernet's DCB toolkit, iSCSI lets TCP absorb loss, and
