—Archiving and compliance vendor Permabit today released version 2.0 of its Permeon Compliance Store, which modularizes its high availability and replication features and adds a new retention policy module. Permeon Compliance Store was introduced in October 2003, and although it is primarily a software product it is delivered to users as an appliance through Permabit's OEM relationships.
"The modular approach allows customers to select the functionality they require and leave other functionality available for purchase later if needed," says Jered Floyd, vice president of development at Permabit.
The newest module is the Retention Policy Module, which allows administrators to define policies for retention filters. Those filters specify if files should be marked "read only" and for how long. It also supports revisions to the policies for changes in government regulations. Files can be transitioned from read/write to read-only as business policies change.
For the High Availability Module, originally released in April, Permabit added automated fail-over. The Permeon Compliance Store high-availability feature is designed to prevent loss of data. "Other vendors often use the term 'high availability' to refer to any system where applications can continue processing data without manual intervention after failure," says Floyd, "but that doesn't guarantee that there will be no data loss. Some systems may lose as much as an hour of recently written data. With Permeon Compliance Store, once a write has been acknowledged by the portal, regardless of what happens, the data is reliably written to the storage system."
The Replication Module features point-in-time replication for one-to-one or many-to-one configurations. Floyd claims that the data in a destination Permeon system will always correspond to a given consistent point in time at the source. "Replication is configured on a file-system-by-file-system basis," he explains, "so only the file systems that must be replicated are, to conserve bandwidth and capacity in the remote system."
Floyd says the many-to-one replication scenario works well for storage service providers (SSPs). Each customer can have its own small Permeon Compliance Store. Each appliance can then replicate to a larger appliance at the SSP's data center. The Permeon Compliance Store is also bi-directional. Two offices can configure each other to be their disaster-recovery site, or to act as their second copy of data to comply with regulations such as SEC17a-4.
Permeon Compliance Store competes primarily with EMC's Centera content-addressed storage (CAS) platform.
Permabit recently received an additional $12 million in funding.
