Sanbolic introduced an interesting software package this week called the Kayo File System, which purports to eliminate the need for dedicated SAN volumes for individual Hyper-V machines.
The software would allow a single shared SAN volume for all machines so they can be moved independently between physical hosts using Microsoft's Quick Migration technology. The system works by providing file-level shared access from multiple hosts, offering an inexpensive means to share LUNS between VMs and resulting in a more streamlined and easily managed storage infrastructure.
The system can be used in conjunction with Sanbolic's Melio FS clustered file system, which offers concurrent read-write access to application data on the SAN from multiple physical or virtual servers. The combination increases the workload that virtual environments can handle, making it easier to scale resources up or down depending on overall data requirements.
The Kayo system is due to hit the channel in August.
