As enterprise Kubernetes deployments continue to scale, aligning infrastructure limits across compute, storage, and orchestration layers becomes critical. In environments combining Red Hat OpenShift Container Platform (RHOCP), Cisco Unified Compute System (UCS), and Hitachi Virtual Storage Platform (VSP) with Hitachi Container Storage Interface (CSI), Logical Unit Number (LUN) scalability and pod density are tightly coupled variables that directly impact performance, stability, and operational predictability. This blog outlines key configuration limits and design considerations to help ensure a balanced, scalable deployment. Cisco UCS Virtual Interface ...

Understanding DRS no-ADR Volumes in Hitachi VSP One BHE

By Sumit Keshri posted yesterday
1 person likes this.
What is DRS no-ADR Volume? A DRS no-ADR volume is a specialized storage volume in Hitachi VSP One BHE systems that supports Thin Image Advanced (TIA) pair operations (along with Shadow Image and remote replication products) but does not apply capacity saving features such as compression or deduplication. DRS no-ADR volume has the capability to enable control data (metadata) to be aware of data management of the Redirect-on-Write (ROW) snapshot function. While working with DRS no-ADR volumes, a temporary increase in pool usage capacity is expected, which should be considered during capacity planning. Managing DRS no-ADR Volume ...

Accelerating DevOps in the Hybrid Cloud: How Hitachi VSP One SDS Block and Red Hat OpenShift Transform CI/CD at Scale

By Chayan Sarkar posted 2 days ago
1 person likes this.
In today’s digital enterprises, software delivery speed defines competitiveness. Organizations are modernizing applications, moving to microservices, and embracing hybrid cloud models to gain flexibility and scale. Yet one persistent challenge slows DevOps teams everywhere: storage . Storage is the backbone of the CI/CD pipeline—powering Git operations, builds, tests, deployment artifacts, and stateful application data. But in hybrid cloud environments, storage often becomes the bottleneck. Public‑cloud block storage can deliver inconsistent performance, on‑prem storage can be difficult to integrate with cloud‑native workflows, and replication across sites ...

Rethinking OpenShift Storage on Google Cloud: Why VSP One SDS Block Wins

By Chayan Sarkar posted 2 days ago
Be the first person to like this.
As enterprises accelerate their shift toward hybrid cloud, one requirement has become non‑negotiable: a storage platform that delivers enterprise‑grade consistency, performance, and resilience—no matter where workloads run. Red Hat OpenShift has established itself as the leading enterprise Kubernetes platform for deploying modern, containerized, and stateful applications. But as organizations run more databases, analytics engines, and event‑streaming workloads on OpenShift, the choice of persistent storage becomes critical. While Google Cloud Hyperdisk is a strong native option, many businesses quickly run into its architectural limitations when running ...

Automating SAP HANA Full-Stack Installation by Hitachi Vantara

By Chandan Kumar posted 2 days ago

Automating SAP HANA Full-Stack Installation by Hitachi Vantara If you've ever been part of an SAP HANA deployment project, you already know the drill. The storage team carves out LUNs. The Linux team configures kernel parameters. The SAP Basis team downloads gigabytes of installation media, manually runs the installer, and hopes nothing breaks. It's a multi-day, multi-team effort, and somewhere in the middle, someone always misses a step. What if you could hit one command and watch the whole thing deploy itself? That's exactly what we built with the SAP HANA Full-Stack Installation Ansible Playbook Pipeline , a fully automated, ...

Bringing Hitachi VSP One Block Storage into Splunk SIEM

By Karthik Raja Balasubramanian posted 4 days ago
1 person likes this.
Why We Built This Enterprise storage does not live in isolation. Servers, networks, applications, and security systems are already monitored inside SIEM platforms, and Splunk is the most widely deployed among them. But storage? Storage has always been the missing piece. Teams managing Hitachi VSP One Block storage arrays had rich, granular metrics available inside VSP 360, but that data never made it into the same operational dashboards where the rest of the infrastructure was visible. We believed this gap was worth closing for every customer running Hitachi VSP One Block storage arrays in a Splunk-centric environment. Storage observability should ...

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

By James Byrne posted 27 days ago
1 person likes this.
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 29 days ago
2 people like this.
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 02-28-2026
1 person likes this.
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.

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.

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

By Vinod Subramaniam posted 02-17-2026

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 ...
