Caringo CAStor 2.0 Delivers Speedy Archival Integrity

Software update provides flexible local and wide-area replication

Caringo, Inc. has updated its CAStor software that combines content-addressed storage (CAS) integrity with the performance of primary disk storage so IT can make archived files continuously available.

CAStor 2.0 eliminates the need for traditional storage tiers used for information lifecycle management systems in which data that is rarely accessed is placed on lower-cost (and slower-to-access) storage. CAStor provides a “flat, single-tier, massively scalable architecture that runs and scales on commodity hardware,” according to Caringo at a cost that is lower than traditional information lifecycle management products. CAStor keeps records online and available when users demand them, combining the speed of primary storage with the integrity of an active archive.

This release also adds asymmetric local and wide-area replication for improved disaster recovery, archiving, and continuous data availability capabilities.

Other new features include:

  • A Web-based management console helps administrators perform everyday tasks and monitor the health of the entire cluster

  • Cluster management with features that allows an administrator to build large, robust clusters which support network booting. SNMP enhancements improve monitoring and management of CAStor clusters by providing performance and capacity metrics

  • Local area replication for disaster recovery let administrators create sub-clusters -- logical partitions within a CAStor cluster used to define storage distribution strategies. Sub-clusters can divide a cluster by location (data cabinet, building location) or can be grouped by nodes based on common infrastructure characteristics.

Administrators can replicate the contents of a CAStor cluster to a remote cluster. Because network connections between the primary and the remote locations are usually slow, CAStor's wide-area replication operates with intermittent, long-haul network links.

The update also includes performance increases for small and medium file operations.
