Scale-out compute-and-storage appliance provider Nutanix has introduced Nutanix OS 3.0 software and a new hardware line, the NX-3000 series to help enterprises build software-defined datacentres.

Nutanix OS 3.0 claimed to deliver VM-level disaster recovery and adaptive post-process compression in addition to dynamic cluster expansion, rolling software upgrades and suppor t for a second hypervisor, KVM.

The new software enhancements are coupled with the configurable NX-3000 series platform to enable enhanced flexibility, performance, and scalability in enterprise datacentres.

Nutanix OS 3.0 includes native storage-optimised disaster recovery that enables enhanced multi-way, master-master replication in traditional storage, the company said.

It enables IT administrators to implement disaster recovery policies that specify protection domains and consistency groups in primary sites, which can then be replicated to any combination of secondary sites to ensure better business continuity and application performance.

In addition, the software also claimed to deliver improved runbook (failover and failback) automation that is hypervisor-agnostic, which means the native disaster recovery capabilities are available and consistent regardless of the underlying virtualisation platform or management tools.

The software is based on MapReduce-based framework that implements information lifecycle management in the cluster to achieve tiering, disk rebuilding, and cluster rebalancing

Nutanix OS 3.0 also supports basic in-line compression that works as the data is being written, which is better suited for archival and sequential workloads.

The software will now support KVM and VMware vSphere 5.1 and uses a discovery-based protocol to auto-detect new nodes added to the same network as a cluster, enabling administrators to expand a cluster without incurring any downtime.

Nutanix OS 3.0 also uses software-defined networking tricks to achieve rolling software upgrades within the always-on cluster.

NX-3000 series will enable Nutanix to deliver an enhanced configurable platform in which compute-heavy and storage-heavy nodes can coexist in a single heterogeneous cluster.

Nutanix’s NX-3000 is based on Intel’s Sandy Bridge architecture and delivers enhanced VM density in a 2U form factor.

The platform will include hardware models that are variable in the capacity and number of PCIe-SSDs, SATA SSDs and SATA HDDs per server node, which can have varying numbers of CPU cores per socket and variable memory capacities.
