Enable Unique Capabilities that Assure Service Levels to Applications
While conventional file systems allow only one server to have read-write access to the same file at a given time, VMFS is a cluster file system that leverages shared storage to allow multiple instances of VMware ESX to read and write to the same storage, concurrently. VMFS allow you to:
- Greatly simplify virtual machine provisioning and administration by efficiently storing the entire virtual machine state in a central location.
- Support unique virtualization-based capabilities such as live migration of running virtual machines from one physical server to another, automatic restart of a failed virtual machine on a separate physical server, and clustering virtual machines across different physical servers.
Seamlessly Manage Virtual Machine Storage
Get virtual disk performance close to native SCSI for even the most data-intensive applications with dynamic control of virtual storage volumes.
- Enable multiple installations of VMware ESX to read and write from the same storage location concurrently.
- Add or delete a VMware ESX server from a VMware VMFS volume without disrupting other VMware ESX hosts.
- Create new virtual machines without relying on a storage administrator. Adaptive block sizing and addressing for growing files allows you to increase a VMFS volume on the fly.
- Simplify storage management with automatic discovery and mapping of LUNs to a VMware VMFS volume.
- Optimize your virtual machine I/O with adjustable volume, disk, file and block sizes.
- Recover virtual machines faster and more reliably in the event of server failure with Distributed journaling.
VMware VMFS cluster file system is included in all VMware Infrastructure editions.
