Scality’s RING product is said to be designed for petabyte-scale storage environments at enterprises, governments and service providers. Leo Leung, vice president of corporate marketing at Scality, reported that the company is seeing serious adoption from the media and entertainment industry as they look to tackle the massive on-demand wave for their customers.
The RING addresses the limits of scaling traditional storage systems to petabytes of capacity. Traditional storage falls down at that scale, said Leung, exposing performance bottlenecks and inefficiencies in data protection, becoming increasingly unreliable as the system grows.
Tintri touts its application-aware storage as providing VM-level visibility, control, insight and agility. The company is all about storage virtualization technology that is said to learn and adapt to existing environments by seeing how applications behave at the virtualization layer.
This is built on its FlashFirst architecture that understands and integrates with VMs and virtual disks. Tintri VMstore then uses flash along with deduplication, compression and data placement automation.
Most recently, it released Tintri OS 3.2 to enable administrators to allocate exact maximum and minimum IOPS to individual VMs. VM-level QoS is paired with visualization of resource contention to view the immediate impact of throttle changes on VM-level latency. In addition, Tintri SyncVM allows users to move between snapshots of a VM without losing other snapshots or performance history. Finally, Tintri Global Center 2.0 makes it possible to manage 100,000 VMs from one interface.
A little known company from Redmond, WA, is also making a push for market share in SDS. Microsoft’s Scale-Out File Server (SOFS) is a clustering initiative that makes file shares continuously available for server application storage. It makes it possible to share the same folder from multiple nodes of one cluster and is built around the Microsoft Hyper-V hypervisor.
Starwind is another startup with a hypervisor-centric approach to SDS. The Starwind Virtual SAN provides a fault-tolerant storage pool that is said to be built for virtualization workloads from scratch. It mirrors inexpensive internal storage between hosts and eliminates any need for physical shared storage.
OpenStack certainly embraces SDS, but it goes beyond it into what it terms a cloud operating system that controls large pools of compute, storage and networking resources throughout a data center. Everything is managed through a dashboard that allows users to provision storage through a web interface.
Actifio characterizes itself as the copy data virtualization company, but it very much operates in the SDS space. Actifio One is a cloud-based service built on its data virtualization technology to make applications easily available. It can run on various physical servers, as well as VMware, Windows, Hyper-v, Linux, Oracle and Microsoft SQL Server.
There are more companies, of course, operating in this space. But those covered in this series provide a good place to start for anyone investigating software-defined storage.
