Versity Storage Manager (VSM) is Versity’s currently deployed large scale archive data management tool for cost-effectively protecting extensive data collections on any mix of storage devices and cloud services.

VSM interfaces with existing enterprise business applications and backup solutions through a standard POSIX file system interface, making it easy to expose low-cost archival storage resources to end-users. Rich and flexible archive policies optimize the data flow both in and out of cloud storage services and archival storage devices such as tape libraries, disk arrays, and on-premise object storage systems.

VSM’s ability to broker data across a diverse mix of archival storage systems enables customers to optimize performance, reliability, and cost factors for different data types.

How it works

Switching from OHSM to VSM: if your organization faces the end of life for OHSM or your Solaris infrastructure, you can move to a more friendly HSM vendor and easily switch from SAM-QFS or OHSM. VSM can restore SAM-QFS or OHSM dump files and immediately begin reading and writing data on existing tape or disk systems. Versity supports a zero data migration conversion from OHMS to VSM with full backward compatibility for OHSM data formats.


Trusted & Proven

VSM was commercially deployed in 2013 and is currently managing over one exabyte of mission critical data across a wide range of public and private sector industry verticals. Customers range in size from small enterprises to the Fortune 50.

OHSM Compatible

VSM and OHSM share the same original code base — Sun’s SAM-QFS. This allows VSM to restore OHSM metadata dump files and read OHSM archival data. Converting from OHSM to VSM is fully supported, and easy to accomplish with zero data migration and minimal training.

Hybrid Cloud

VSM supports S3 and Azure cloud copies enabling the use of public cloud storage for primary or disaster recovery data.
