Lower Total Cost of Ownership

6Gb/s SAS Diagnostics and Backward Compatibility

Lower your Total Cost of Ownership (TCO) and protect your investment with 6Gb/s SAS diagnostics and backward compatibility

6Gb/s SAS provides many enhancements for performance, management and reliability in SAS storage topologies:

Status information for every link in the system improves fault identification and isolation.
Self-test functions within 6Gb/s SAS devices provide fault analysis and logging functionality to validate failure conditions.

These features potentially reduce system downtime, service calls and warranty returns of devices that are erroneously reported as failed.

SAS is known for its performance and compatibility with Serial ATA (SATA) drives. 6Gb/s SAS extends that capability with full backward support of SAS 1.1 and SATA I and II, enabling you to mix 6 Gbit/s SAS, 3 Gbit/s SAS, 3 Gbit/s SATA, and 1.5 Gbit/s SATA devices. What’s more, 6Gb/s SAS promises to support technology advances well into the foreseeable future so you’ll be ready to take advantage of it.

With 6Gb/s SAS, your investment is protected and future-proofed, extending the life of your data center.
