AI inference refers to the execution of already trained AI models to generate predictions, classifications, or content. Unlike training, model weights are not continuously updated during inference. Instead, AI inference systems must process requests at defined throughput levels and within specified latency limits. For IT architects deploying LLM serving platforms, real-time recommendation engines, or computer […]
MI455X vs. Rubin: Who plans AI training, inference or HPC infrastructure with HBM4 accelerators must weigh different GPU and rack-scale architectures. Both are designed for liquid-cooled rack systems. AMD positions MI455X for AI inference, training and fine-tuning; NVIDIA positions Rubin for training, post-training and inference and for scientific computing. At first glance the published specifications […]
SAS vs. SATA is a key consideration when selecting server storage, as the two interfaces differ in performance, reliability, fault tolerance, and cost. Both connect hard disk drives and solid-state drives to server controllers, but they are designed for different requirements and workloads. This article compares SAS and SATA in terms of command processing, fault […]
High Bandwidth Memory is one of the central specifications of an accelerator for AI and machine learning workloads, because the model and its working data have to fit into it. JEDEC published the HBM4 standard in April 2025, and the first commercial HBM4 shipments were announced in February 2026. This article explains what HBM4 changes […]
SAS (Serial Attached SCSI) is a serial point-to-point communication standard for connecting storage devices in server and enterprise storage systems. SAS supports, among other features, full-duplex data transmission, SAS expanders, and, with corresponding enterprise drives, redundant data paths through dual-port connections. When evaluating enterprise storage for database servers, virtualization hosts, or RAID arrays, data sheets […]
For IT procurement specialists and network engineers specifying server infrastructure, the transceiver landscape presents a confusing array of similar-looking form factors with vastly different capabilities. SFP+ looks identical to SFP, fits the same physical port, yet delivers ten times the bandwidth — and that physical compatibility masks important functional limitations that affect purchasing decisions and […]
A JBOD — “Just a Bunch of Disks” — is a disk enclosure architecture that exposes individual drives directly to a host system or external storage controller without performing hardware RAID operations. The key difference between JBOD and RAID lies in where the storage logic and redundancy are implemented. Unlike intelligent storage arrays with onboard […]
RAID combines multiple drives into a logical volume — but which configuration matches your requirements? The choice between RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10 determines usable capacity, performance, rebuild duration and failure tolerance. This article explains how each RAID level works, which deployment scenarios they serve, and how to weigh […]
For edge deployments, branch offices, and workloads that fit within a single CPU socket, the socket decision determines not only the server platform, but also power consumption, licensing costs, and Total Cost of Ownership. AMD EPYC 8004 – marketed as Siena – brings the EPYC architecture to single-socket systems with up to 64 cores, six […]
