Why HCI

Why enterprises are retiring three-tier infrastructure

The same workloads. A fraction of the operational complexity.

Eliminate Data Center Complexity
Replace three separate systems — compute, storage, and network — with one unified platform. One management interface, one team, one contract.
Cut Total Cost of Ownership
No specialized storage hardware markup. Deploy on commodity servers you already own. Scale by adding nodes, not by buying new SAN arrays.
Scale Without Disruption
Add capacity by adding nodes — no downtime, no migration projects. Scale compute and storage independently based on actual demand.
No Vendor Lock-in
Runs on standard x86 and ARM64 servers from any certified manufacturer. No proprietary appliance lock-in. Choose your preferred vendor.
Architecture

Three layers to one unified stack

Compute virtualization, software-defined storage, and network virtualization — fully integrated and managed through a single control plane.

Core Capabilities

Built for enterprise IT

Everything you need to run your data center, in one integrated platform.

Minimal Deployment
One-click initialization. Cross-version upgrades with zero service interruption.
VMware Migration
Built-in V2V migration — UI-driven, no scripting required.
High Performance
NUMA binding, large-page memory, OVS-DPDK, SR-IOV acceleration.
Enterprise Reliability
Hardware redundancy, multi-link HA, flexible data protection.
Layered Security
Network isolation, distributed firewalls, 2FA, operation auditing.
Deployment Options

Deploy the way you need

Choose the configuration that matches your workload and budget.

All-Flash HCI
Maximum performance for core production workloads with demanding I/O requirements. Three-replica storage with compute HA.
Standard HCI
Cost-effective for general business applications and testing environments. Mixed disk configuration for balanced performance.
Compute + Storage Separation
For workloads requiring independent scaling of compute and storage resources. Flexible resource allocation.
Total Cost of Ownership

The economics of consolidation

Real savings across the entire infrastructure lifecycle.

01
Lower Acquisition Cost
Replace separate compute servers, SAN arrays, and network switches with standard commodity servers.
02
Lower Operational Cost
One management interface replaces three. One team manages everything with unified monitoring.
03
Non-disruptive Scaling
Add capacity by adding nodes — no downtime, no migration projects. Scale independently.
04
Protect Existing Investments
Deploy on servers you already own. VMware workloads migrate in-place. No rip-and-replace.
Use Cases

Built for every scenario

From core production to edge deployment — one platform handles it all.

Scene 01
Core Production Workloads
Databases, ERP, financial systems

Deploy in all-flash HCI with three-replica storage and compute HA. Business fault detection maintains uptime for financial-grade systems.

All-Flash 3-Replica HA
Scene 02
Test and Development
Maximize utilization, minimize overhead

Deploy on existing servers or purpose-built appliances. Static allocation and dynamic scheduling ensure test environments get what they need.

Dynamic Sched Cost-Effective
Scene 03
Disaster Recovery
RPO = 0, RTO ≈ 3 minutes

Establish an application-level DR site. Distributed storage extension clusters achieve RPO=0 for critical systems.

RPO=0 App-Level DR
Scene 04
Edge and Branch
Small footprint, full capability

Minimal node deployment starting from 3 nodes brings full HCI to branch offices — with centralized management from HQ.
