Allows multiple servers to connect to one or more independent external storage systems
LSI is sampling its new series of 6Gb/s SAS switches that extend the capabilities of SAS in direct-attached storage (DAS) environments, allowing multiple servers to connect to one or more independent external storage systems.
The company said that the LSI model SAS6160 and SAS6161 switches are designed to provide a low-cost and easy-to-use shared storage option for rack-mounted server and storage installations in cloud computing, mega data centre and small- to medium-sized business environments.
According to LSI, the SAS616x series of switches feature zoning, which enables storage resources to be shared across multiple hosts, helping to maximise storage resource utilisation, eliminate islands of storage and simplify storage management, backup and upgrades.
In addition, based on enterprise-hardened LSI silicon, firmware and software, the SAS616x series switches feature a rack-mountable 16-port, 1U profile in respective half-width and full-width form factors for installation with rack-mounted servers and are compatible with existing SAS infrastructures.
LSI said that both the models feature 24Gb/s SAS connections on 16 x4 SAS lanes to deliver an aggregated bandwidth of 384Gb/s. Each model supports SAS and SATA connectivity to more than 1,000 devices, enabling customers to take advantage of larger SAS topologies and tiered storage offering.
LSI SAS616x switches offer SAS domain management including port configuration, zoning, firmware management, diagnostics and viewing of the SAS topology.
Steve Fingerhut, senior director of marketing for storage components division at LSI, said: With fully integrated management software and extensive end-to-end interoperability testing, customers are assured of plug-and-play simplicity when deploying SAS616x series switches into existing SAS-based environments.
Production quantities are expected to be available to OEM customers in the second half of this year.
