Building an AI Agent with Python, Ollama, and PostgreSQL – a Practical Guide

By Koustab Bose posted 4 days ago

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think, learn, and make decisions. AI enables computers and systems to perform tasks that typically require human intelligence, such as problem-solving, understanding language, recognizing images, and making predictions. AI is largely categorized into 2 types: Generative AI and Agentic AI . Generative AI is a type of artificial intelligence that creates new content such as text, images, music, or code based on patterns learned from data. Agentic AI refers to AI systems that can act independently to achieve goals by making decisions, planning steps, ...

MPB Load Balancing on VSP One Block and VSP One Block High End using VSP 360 REST API

By Vinod Subramaniam posted 4 days ago

VSP 360 REST API - Load balance MPB's on VSP One Block and VSP One Block High End. When LDEVs are created they are assigned in a round robin fashion across all the MPB's [ Microprocessor Blades ]. Over time as LDEVs are created and deleted the number of LDEVs on each MPB may not be the same. Also as load shifts over time the MPB's may become unbalanced. Another scenario is when you upgrade a 2-node Block High End array to a 4-node etc. VSP 360 shows this on the dashboard. Select "Processor Load Balance". The below shows a imbalance in IOPS across two B28 MPB's. Note that this is an example only as the MPB's are actually balanced inspite of the IOPS ...
