QStar LTFS as NAS architecture virtualizes a tape library, effectively converting it into network-attached storage – NAS for sharing with multiple users and applications.
Users can browse the file system using Explorer type searches while “archive aware” applications, such as MAMs, Video Surveillance, Healthcare PACS and email archive, can archive data directly to a network share or mount the tape library.
The solution supports common networking protocols (SMB and NFS) plus S3 compatible API commands and is integrates on either a Windows or Linux server.
Files that are stored in a LTFS as NAS environment are retrieved in the same manner as the native operating system, even though the data is actually stored in a tape library.
Not only do users not realize that the volume (file system) they are accessing was created on tape and not on disk, but, through a sophisticated cache architecture, the read/write data activity is managed so effectively, that performance is comparable to a NAS device.
Transparency is such that the architecture is also supported by virtual machine (VM) environments, even though the VM environment is not designed to support tape drives; existing applications installed in a VM can access the Tape as NAS architecture just like a standard NAS disk. Data can be accessed transparently over the network.
