For a couple of years, Homescape, which offers online marketing for real estate agents and brokers, struggled to migrate data across volumes of an HDS 9970 storage platform, using FalconStor data migration wares and PolyServe Oracle database server clustering software. When Homescape added 3PAR's hardware, the group was able to ditch HDS/Falconstor.
Using PolyServe's LUN concatenation with 3PAR has boosted performance significantly, Pejril says. On top of that, storage procurement is streamlined.
"With 3PAR's thin provisioning, we can use 33 percent of a terabyte volume and have breathing room for another year."
It doesn't bother her that PolyServe still requires administrators to manage the operating system of multiple servers individually. "Most of our management time is spent managing disk," she asserts. Having a cluster reduces that substantially, despite the fact that the OS must still be configured separately on each server in the cluster.
At least one analyst also points out that the combination of 3PAR and PolyServe, as adopted in the Homescape example, is a good utility computing solution. "The hidden diamond here is PolyServe's ability to move databases from server to server in a utility manner," says Greg Schulz of the StorageIO consultancy. He notes that while PolyServe also supports files, it's the database allocation across multiple servers using pointers that really enables the pooling of capacity for users like Homescape.
