Clustering Choices Expanded
Xiotech Corp. is aiming to fill the dearth of clustering options in enterprise storage with its new Magnitude three-dimensional array.Xiotech Corp. is aiming to fill the dearth of clustering options in enterprise storage with its new Magnitude three-dimensional array, according to company officials."What weve done is taken a pure clustering approach, broken up into layers," said Xiotech Corporate Architect Rob Peglar, in Eden Prairie, Minn. Storage administrators today have many third-party application clustering options, and replication software can protect a SAN (storage area network) if there are two of all the hardware, but vendors such as EMC Corp., Hitachi Ltd. and IBM include only primitive controller redundancy by default, Peglar said.
Thats fine for array failover, but its not suitable for data center emergencies, as its not distributed, Peglar said. EMC, of Hopkinton, Mass., last week announced updated replication software, Symmetrix Remote Data Facility/ Asynchronous, or SRDF/A, that copies only data changes. That eliminates the need for full dual-storage environments, but it doesnt ship until next month and costs users an extra $20,000 to start.
