Software-defined storage: The pros and cons, and what is available

As a software-defined storage marketplace evolves, dual resisting approaches are being taken by storage suppliers. Specialist software-defined storage suppliers have changed to offer stereotyped hardware platforms for their products, since array suppliers have started to furnish program versions of theirs.

Software-defined storage products that are accessible with stereotyped hardware configurations embody Maxta with a MaxDeploy configurations, Atlantis Computing with HyperScale, and Dell-EMC with a ScaleIO Ready Nodes.

Some business simply do not wish to pattern their possess hardware, so by providing a program and hardware resolution with reduction mark-up, these suppliers have found a center belligerent and used a event to focus some-more towards hyper-convergence.

Meanwhile, Dell-EMC and HPE yield program versions of their hardware offerings, including HPE StoreVirtual (Equallogic), HPE StoreOnce, Dell-EMC Unity and Data Domain Virtual Edition.

These are entirely upheld platforms that have minimal ability and additional paid-for licences.

NetApp used to offer a software-only doing of Data ONTAP, though that appears to have been discontinued. The association does offer a software-only chronicle of a SolidFire handling complement that can be deployed on specific hardware configurations.

Another area of software-defined storage adoption is object storage. Object stores are good matched to being deployed on commodity storage, where throughput, rather than latency, is an critical metric.

Almost all intent storage suppliers – including Scality, Cloudian, Caringo, Cleversafe/IBM, OpenIO and NooBaa – can be deployed as software, possibly onto unclothed steel or as a practical machine.

In a cloud, we see offerings from existent storage suppliers, both array makers and software-defined.

NetApp offers Data ONTAP as ONTAP Cloud for AWS, SoftNAS has CloudNAS and Zadara Storage has VPSA, a hardware-based SDS offering. Meanwhile, Cloudian HyperStore is accessible as an AWS AMI (Amazon Machine Image) and Panzura offers a Global Cloud Storage System.
