Software-defined storage (SDS) and hyperconverged infrastructure (HCI) have the same end goal: to add flexibility, scalability, and efficiency to storage, but the methods to achieve those objectives differ between the two. The difference between software-defined storage and hyperconverged infrastructure is that SDS is the virtualization of storage by separating the control and management software from the hardware architecture. A subset of SDS, HCI uses software-defined networking to consolidate the compute, network, and storage components.

Hyperconverged infrastructures (HCI) are gaining popularity from the edge to the core where IT teams are looking to reduce the complexity and cost overheads of running a three-tier environment with servers, storage systems, and network fabrics that are separately implemented, configured, and managed. HCI consolidates servers, storage, the hypervisor, and some network functions into a software-centric solution deployed on commodity hardware.

The simple converged form factor of an HCI appliance enabling rapid deployment, its predictable scalability, and high availability make it a compelling technology to run various workloads. IT organizations can start small with HCI and grow linearly on demand thereby reducing upfront infrastructure costs and hardware footprint.

SOFTWARE-DEFINED STORAGE FOR HCI ENVIRONMENTS

DataCore SANsymphony software allows you to customize your HCI cluster based on your choice of components (server, hypervisor, CPU, RAM, network, SSDs, HDDs) and vendors. You can run your HCI platform on its own or seamlessly integrate it into your broader storage infrastructure, while managing all storage resources under a single platform.

FEATURES AT A GLANCE

  • Ensure high availability and uninterrupted access for your data 
  • Enhance application performance and response times 
  • Automate data services, such as tiering, snapshots, replication, and more 
  • Choose components from a variety of vendors for truly flexible deployment 
  • Extend your HCI storage to serve non-HCI applications 
  • Scale compute and storage independently (for example, with external storage)

SMALL DATA CENTER

SANsymphony can be deployed on a small data center infrastructure which runs two HCI nodes and can scale out as needed. Standard x86 servers can be customized into HCI nodes paired up for high availability. No separate storage is required. Based on the business demand, SANsymphony can scale from 2 to 64 nodes. Additionally, when there are applications running separately on nonHCI servers, they can access storage from SANsymphonypowered HCI nodes.

DEDICATED APPLICATION CLUSTER

When IT requirements need specific applications to run in a separate cluster outside of the core data center servers and storage infrastructure, SANsymphony can help run them on a HCI platform separated from, yet integrated with, the primary data center. Benefits include improved storage management across the data center, including the dedicated application cluster, with a centralized control plane.

ULTIMATE FLEXIBILITY: NO VENDOR LOCK-IN OR DEPLOYMENT CONSTRAINTS

DataCore lets you make the best use of the equipment you already own unlike typical hyperconverged vendors that lock you to their offerings. When the time comes to expand or replace it, you have complete freedom to select hardware from other suppliers. That puts you in the driver’s seat when negotiating your next purchase. And, if you eventually need to transition to a converged deployment model, leverage separate storage, or serve hyperconverged storage to non-HCI applications, you can do so seamlessly without disrupting your business operations.

EXTENSIBLE ARCHITECTURE ADAPTS TO FUTURE NEEDS

Scale compute and storage independently for your HCI environment on-demand and reduce IT spending. Seamlessly tap into capacity on external SANs, all centrally controlled from the same console. You can also configure non-HCI servers to access storage from HCI nodes. SANsymphony lets you easily integrate new technology into your HCI cluster without painful data migrations and forklift upgrades. And you can also non-disruptively migrate between traditional SAN, hyperconverged, and hybrid environments as the business demands with no impact on your applications.

COST-OPTIMIZED HIGH AVAILABILITY

SANsymphony enables you to achieve true high availability using just two HCI nodes. By synchronously mirroring data in real time to a secondary HCI node, SANsymphony ensures data availability for your mission-critical applications.

WELL-SUITED FOR MIXED HYPERVISOR ENVIRONMENTS

If you use different hypervisors for different workloads or are migrating from one hypervisor to another, SANsymphony works on VMware vSphere and Microsoft Hyper-V letting you provision storage to the hypervisor the same way you provision virtual compute resources.
