With the growing development of cloud services, companies are gradually migrating their workloads without giving up local resources to power traditional applications and meet certain regulatory constraints. It then remains to manage the various cloud providers and to reconcile them with the on-premises requirements and constraints. Founded in Bulgaria, with a branch in the United States, Tiger Technology helps companies transparently expose their NTFS storage between different destinations with easy-to-implement policies. Hybrid workflows with Tiger Bridge thus remain compatible with the company’s Active Directory.

“Our Tiger Bridge solution, which does not rely on a physical gateway, extends NTFS resources to NAS, DAS, tape and cloud in automatic tiering mode”, told us Alexander Lefterov, CEO and founder of Tiger Technology, during a IT Press Tower in Sunnyvale, California. Tiger Bridge – with Tiger Pool to extend NTFS volumes and Tiger Store to support collaborative workflows – moves data from a local storage platform to cloud resources, regardless of vendor. Data can also be transferred – always transparently – to online archiving solutions for long-term retention. While Tiger Bridge optimizes data placement for frequent access, ready-to-archive files, and near-line files, it still preserves Active Directory Access Control List (ACLs) while ensuring that data is stored In the right place at the right time.

Concretely, Tiger Bridge installs a connector on Windows servers which then ensures the transparent extension of NTFS, Tiger Pool or Tiger Store primary storage to secondary storage (an LTO library with Tiger Bridge-T; SMB transfer in block mode with Tiger Bridge -D; transfer to a RESTful/S3 object platform with Tiger Bridge-C). An NTFS, Tiger Store, Tiger Pool storage space can be used as a primary or secondary volume (see illustration below). The latter can be exploited for replication, prioritization, overflow or simply to synchronize the primary storage with the secondary.

Tiger Bridge’s HSM (Hierarchical Storage Management) tiering and synchronization engine protects and extends the NTFS file system to DAS/NAS, tape and cloud and optimizing data placement for frequently accessed files, close to production and ready for archiving. When a file has been moved to secondary storage and needs to be deleted from source storage, an alias containing all metadata is kept on primary storage for users and applications. Note that the data format remains the same. “They are native, specified Lance Kelson, vice-president at Tiger Technology, they are encapsulated in object mode with metadata”. Note in conclusion that the pricing of the Tiger Bridge solution is based on the volume managed: i.e. $3 per TB per month for the basic formula (without replication and without HSM) and up to $13 per TB per month to benefit from all the platform features.
