IBM Spectrum Scale vs StarWind Virtual Tape Library comparison

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.

For SMB and Enterprises, who either look to get rid of backup tapes completely, or are willing to accelerate backup process and add an extra level of protection, our solution is StarWind Virtual Tape Library (VTL). It is an appliance that eliminates the need in physical tape and “pretends” to be a supported tape drive or autoloader, keeping all data on inexpensive, fast and high-capacity spinning disks.

Even with explosive data growth, StarWind VTL fits the backup into backup window by accelerating it, so the process does not overlap with production time. Optionally, it creates additional copy of backup data for better safety. It is also available in a software-only form, as part of StarWind VSAN functionality. 

StarWind VTL targets those, who need to replace existing tape backup infrastructure or accelerate it if regulatory requirements prohibit replacement. In case the goal is just virtualizing tape backup or creating a stretched backup infrastructure, StarWind Tape Redirector will come in handy.
