From SNIA, SAS Roadmap Updates

The SAS (Serial Attached SCSI) Roadmap was updated recently, defining key advancements in the technology’s future.

Highlights include:

• Command Duration Limits (CDLs): offers more control over HDD latencies
• Logical Depopulation (Depop): allows drives to degrade in place
• Rebuild Assist for SSDs: improves RAID rebuild times
• Persistent Connections: reduces overhead for higher performance.

Updates under consideration are:

• SPDM Capability for device authentication and security
• Protection Information (PI) fields for greater data reliability
• SAS continues to be a robust option for high-performance and scalable enterprise storage systems.

Notes:

• This roadmap shows the availability of prototypes and end-user products for each generation of SAS.
• Plugfest is an event where industry participants test their prototype products to confirm interoperability.
• End-user products typically become available approximately 12-18 months after the first Plugfest.
