IT operations are becoming increasingly complex for enterprises. If your organization is still relying on the traditional three-tier architecture, it’s high time to move to more robust, future-friendly solutions like hyperconverged infrastructure (HCI).
Traditional three-tier architecture comprises three layers: the presentation tier for user interfaces such as web pages, the application tier for business logic and processing, and the data tier for databases and storage. Each runs on separate servers.
But what is HCI? Well, it’s the newest and an agile path to digital infrastructure. HCI combines compute, storage, and networking to create a unified, centrally managed software-defined server virtualization platform. The benefits of this software-defined storage include reduced complexity, simplified management, faster operations, and IT cost optimization.
Although it is currently the most advanced solution for digital infrastructure, many enterprises are still new to it.
We have simplified everything about HCI, what it stands for, how it helps, and how to adopt it into an enterprise through this comprehensive blog post. Keep reading.
Core Principles of HCI Architecture
Starting with the first question, “What is HCI?” HCI is an IT framework that combines compute, storage, and network into a single software-defined platform.
This unified approach reduces IT complexity by reducing the hardware required for IT operations. Also, due to HCI’s software-defined solution, it’s very easy to scale it according to the organization’s needs. Users can rely on the pay-as-you-go model of HCI and pay for the extra nodes added to the system to meet business-specific requirements.
Modern HCI architectures collapse silos and build a software-defined data centre solution. It’s very easy to operate and quick to install for business-critical applications. Most importantly, enterprises can develop their own private cloud, extend to a public cloud, or build their hybrid cloud environment with HCI. Compared to traditional converged systems, the tight software integration of HCI reduces the total cost of ownership (TCO) for users.
Virtualization at the Heart of HCI
Virtualization is the core fundamental of HCI. The hypervisor abstracts hardware, enabling multi-VM deployments with centralized management.
As a result, users benefit from the visible and unified operation through a single web console, rapid VM provisioning, and consistent policy enforcement.
From Concept to Deployment: A Practical Roadmap to Deploying HCI
Adopting or migrating to HCI from traditional IT infrastructure requires a phased approach. Enterprises must start with a close assessment of their environment and virtualization needs. Next, they must go through a cluster architecture design and finally deploy or migrate to a new virtualized platform. Here’s a three-stage process of HCI deployment:
1. Assessment & Sizing
The first step in any HCI journey is through assessment. When adopting HCI, enterprises must assess and analyze their current workload, CPU, memory, and storage requirements.
Next, they must establish performance baselines like IOPS and latency. A well-thought-out growth projection helps avoid risks of under-sizing, especially when the enterprise may need to scale in the future.
Sangfor’s Approach: Sangfor simplifies this process with its HCI Compatibility Chart, which verifies hardware and OS support, ensuring smooth deployment without surprises. This proactive validation reduces risk and accelerates implementation.
2. Cluster Design
Once sizing is complete, design the cluster architecture. It’s best to start with a minimum of three nodes to maintain resilience and quorum. This approach ensures high availability even if the nodes fail.
Next, enable different data services such as snapshots, backup, and Continuous Data Protection (CDP) to meet stringent RPO/RTO goals for disaster recovery. The integrated SDS (aSAN) and SDN (aNET) make it simple to configure storage policies and network segmentation without relying on external tools.
3. Deployment & Migration
HCI deployment and migration can be easier through pre-integrated appliances and software-defined solutions that abstract hardware, allowing quick setup and easy management from a single interface.
Sangfor’s Approach: Sangfor streamlines this process with guided wizards that automate cluster setup, network configuration, and storage pooling. This approach reduces the chances of manual errors and speeds up the time to value. Enterprises can move their workloads to the HCI fabric with minimal downtime when choosing Sangfor HCI.
Why Enterprises Evaluate VMware Alternatives?
Whether moving away from the traditional IT infrastructure or choosing a VMware alternative, enterprises must evaluate their options first. The key reasons for evaluating a hyperconverged infrastructure (HCI) vendor include:
- Licensing and ecosystem changes incur additional costs for organizations.
- Reassessing virtualization strategy and finding the right fit.
- Evaluating the subscription costs of HCI vendors to ensure cost optimization.
- Ensuring flexibility and integration with existing hardware and systems.
- Ensuring ease of scalability for the future.
Also, the market for HCI is evolving with new VMware contenders coming up with different licensing tiers, per-core metrics, and evolving renewal policies.
