Customer stories |
|
|
Three real scenarios. Three moments when High Availability made all the difference. |
|

|
|
| Why businesses need High Availability now more than ever |
| The cloud isn’t fail-proof |
| When external networks or cloud services go down, SaaS and remote systems are instantly affected. |
|
| A local, controllable HA architecture keeps your critical services running even during outside disruptions. |
|
|
| Backup ≠ Service continuity |
| Backups restore data—but they don’t prevent downtime. |
|
| Only HA can take over automatically during hardware or system failures, keeping users online without interruption. |
|
|
| Centralized IT = Greater impact when failure strikes |
| VMs, file services, collaboration platforms, and databases often reside on a single NAS. |
|
| One failure can halt the entire organization. |
|
|
| Downtime costs more than you think |
| A single prolonged outage can cost far more than investing in HA. |

From storage to networking |
|
|
QNAP’s complete High Availability solutions |
|

| Two NAS systems form an Active-Passive cluster. If one fails, the standby takes over instantly, ensuring continuous service and no data loss. |
|
|
|
| Benefits |
 Affordable HA for small and medium-sized businesses |
| Primary/standby data remains fully synchronized |
| Automatic failover and recovery |
| Manual switchover for maintenance—no downtime required |
| Ideal for file services, essential databases, and business applications |
|
|

|
|
| MC-LAG Network Redundancy |
| Many companies secure their storage but overlook the network—a common single point of failure. With QNAP switches supporting MC-LAG, critical devices stay connected even if one switch goes offline. |
|
|
|
| Benefits |
| Eliminates core-switch single point of failure |
| Update or replace one switch without disrupting service |
| Integrates with Port Trunking/LACP for bandwidth + redundancy |

|
|
|
|
|
|
|
| Virtual Machine (VM) High Availability |
| Your CRM, order system, and reporting tools run on VMs—and when they stop, your entire workflow halts. QNAP VM HA keeps these services running with just two NAS systems, enabling automatic failover and zero-downtime maintenance. |
|
|
|
| Benefits |

| No extra shared-storage hardware, reducing cost and complexity |
| Enable HA only for selected VMs; no impact on other NAS workloads |
