Hitachi Data Protection Suite (HDPS) Migration: Get to the Cloud and Back

By James Byrne posted 9 days ago

Introduction Every cloud migration project seems to start with the same document: how do we get to the cloud? It’s usually detailed and step-by-step. The document that’s often missing is just as important: how do we get back out if we need to? HDPS is typically viewed as a backup and recovery platform, but it can also be used as a practical migration tool. If migration is the act of bringing workloads up somewhere else with confidence, then a platform built for reliable restore operations can become the backbone of that move. This approach has two big advantages: you can rehearse the migration before cutover, and you can treat “exit” as a planned ...

Hitachi Data Protection Suite (HDPS) VMware Backup: Selecting the Proper Transport

By James Byrne posted 11 days ago

Hitachi Data Protection Suite (HDPS) VMware Backup Transport Modes: NBD vs HotAdd vs SAN A practical guide to choosing the right data path for faster, safer VMware backups and restores with Hitachi Data Protection Suite. When a VMware backup “feels slow,” the bottleneck is often not your backup target or your dedupe ratio - it is the path your backup infrastructure uses to read virtual disk blocks out of vSphere. In VMware image-level protection, that path is controlled by the transport mode. The same HDPS storage policy can perform very differently depending on whether the data is being pulled over the LAN (NBD), read locally inside the cluster (HotAdd), ...

VSP360: Simplifying SAP HANA TDI Storage Provisioning on VSP One Block 20

By Sameer Bansal posted 14 days ago

Organizations running scale‑up or scale‑out SAP HANA TDI often provision storage manually through storage GUIs or CLI tools. Different storage models require different tools and workflows, which is time‑consuming and prone to human error. In scale‑out SAP HANA deployments, this challenge grows further because storage must be configured individually for multiple HANA nodes, leading to significant manual work and extended setup time. SAP HANA tailored data center integration (TDI) each installation is customized by assembling hardware, operating system, and hypervisor (optional) from SAP-certified components.

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

By Koustab Bose posted 24 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 24 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 ...
