DataCore Software, a provider of storage virtualization software, announced that iomart hosting, a managed services provider, is using DataCore’s SANsymphony solution to provide the backbone for iomart’s hosted customers.
iomart hosting offers managed services ranging from a single server to complex managed environments. Recently, to help clients facilitate cloud computing, iomart launched a dedicated, virtualized server service, offering VMware dedicated servers capable of running multiple operating systems and applications from one physical server.
With these services in mind, the challenge that iomart faced was managing 30TB of storage across a heterogeneous environment. The suggested environment from DataCore involved using standard x86 hardware, each having 128GB RAM for caching, four Quad Core Processors and 8GB HBAs for connectivity. The disk that sat behind the server was classified as a low-end commodity disk. On top of this hardware, DataCore’s SANsymphony solution was used in a mirrored SAN-SAN configuration to virtualize and manage the environment across a fiber link.
Mirrored high-availability between sites over 20 miles away also provides iomart with enhanced disaster recover capabilities, according to DataCore.
DataCore’s synchronous replication functionality operates on a forced cache coherency model, based on a grid architecture that replicates the I/O block between the cache on each DataCore server before sending the acknowledgement to the application server and committing the data to disk.
