Hey, VMware. You've got competition – from a Belgian upstart

Did we mention this open source object store isn't just targeting VMware?

Designing a Defense for Mobile Applications

Belgian startup incubator CloudFounders has an open source project to provide an networked object storage backend to VMware or KVM virtual machines using a VSAN-like Open vStorage Router (OSR).

OSR is a VMware VM, or runs on bare metal in a KVM server, and it scales out by having OSR run on additional virtualised servers linked by 10GbitE, providing a unified NFS namespace across them.

It is VM-aware and provides access to vPOOL storage to them, talking, as it were, VM language to VMs and object-style language to back-end arrays that are running under Ceph, Gluster, OpenStack Swift or other object storage operating systems.

The OSR turns a container on Swift into a VM Volume and that volume can only be presented by a single OSR. There is a handover between OSRs if a vMotion operation makes that necessary.

The OSR is used for provisioning (thin), snapshotting, replication and cloning (thin), and all are actioned at the VM level.

OSR also uses server-attached SSDs or PCIe flash as a cache facility, for both reads and writes. Cache hits accelerate performance for reads. The write-back caching is said to solve the IO-blender problem by turning random writes into sequential ones. Write cache data is written to the backend store, with a zero-copy approach, when a storage container object is full, typically set at 4MB.

The read cache is deduplicated and is shared across hosts. There is a failover cache facility with writes to a write cache being synchronously replicated to another node.

With vMotion IO is redirected and a vDisk automatically follows the vMotioned VM.

A single OSR can talk to multiple back-ends. It’s anticipated that the XEN hypervisor will be supported in the future, as will VirtualBox and Hyper-V.

The Open vStorage router competes with VMware’s VSAN and other virtual storage appliances. The project is being run from Lochristi in Belgium and Cloud Founders has an Amplidata involvement.
