XOSAN is a virtual SAN that allows you to create a shared SR (Storage Repository) by combining your existing local SRs. It's a software defined and hyperconverged solution for XenServer.


This documentation will give you some advices and assistance in order to create a XOSAN storage on your XenServer infrastructure.


XOSAN will "gather" all your local disks into a shared SR, that XenServer will just see as any other shared SR, without limitations on it (you can live migrate, snapshot, backup, whatever you need). It's a fully software defined solution that doesn't require to buy extra-hardware. It could even run on the disk where your XenServer is already installed!

The objectives are to:

  • protect your data thanks to replication of data on multiple hosts
  • provide XenServer high availability without buying a NAS nor a SAN
  • give you flexibility to grow your storage by adding new nodes
  • work on all kind of hardware, from HDDs to SSDs, with hardware RAID or not
