VSAN(Storage Virtualization)
VSAN(Storage Virtualization)
Integrated Hyper Converged Infrastructure (HCI) based on vSphere and VSAN enables you to manage compute and storage from a single unified platform using a software defined approach.
VSAN Architecture
VSAN is an object virtualized storage software that creates shared storage for virtual machines and cloud native apps, virtualizes local physical storage resources on ESXi hosts, and then dynamically uses them according to service quality requirements
Why VMware VSAN?
-
1. Integrate to vSphere· HCI embedded in hypervisor kernel increases CPU and memory efficiency
· Single management window from vCenter
-
2. Lowest price per IOPS HCI benefit· Leverage disks for x86 servers from any vendor without external storage
· Scale out & up storage as easily as you need capacity performance
-
3. Simplified operations· Software-adjusted storage policies to fit workloads rather than storage hardware structures
· Integrated management of HCI server and storage infrastructure with vCenter
-
4. SDDC & Support Cloud· Validated standard HCI standards facilitate SDDC and cloud alignment and expansion
· Integrate with VMware NSX, vRealize, Horizon, and more to build a software-defined data center
Difference between VMware VSAN and other HCI
| division | VMware vSAN | Third-party HCI products | |
|---|---|---|---|
| Performance safety | hypervisor kernel integration in VMware ESXi |  |
 |
| Integration | Compatible with a variety of standard x86 servers rather than dedicated appliances | |
|
| Management convenience | Provides a completely integrated dashboard for vCenter in vSphere (no separate plug-in configuration required) | |
|
| Scalability | Extension to VMware SDDC | |
