3.0 Enhancements
• SFA7700: Added licensed feature, SFX Read. SFX Read support makes use of SSDs
to to assist with servicing host I/O for re-reads residing in cache, and prefetch based
on I/O patterns.
• SFA12K-40 now supports up to 20 SS8460 enclosures.
4.0 Resolved Issues
4.1 Common
These issues have been resolved.
• Apache HTTPD configuration change to prevent a denial of service attack via the
management network interface.
DE1016
• BBU/UPS monitoring has been improved to reduce false failure messages.
• Fibre Channel attached systems may see improved performance for some
workloads.
DE9974
• Controller metadata known as the config was not completely written during a brief
power loss resulting in missing configuration information. This caused a subsequent
controller crash to occur. This issue has been resolved. DE9083
•
The API method SFADiskDrive.getAll() request would not complete which resulting
in the client application being unable to display controller metrics. This has been
fixed in this release. DE10269
4.2 SFA7700
• The combination of SFA OS version 2.1.1.2 and SFA7700 FPGA version 1.14-0.40 will
detect rare FPGA failures and automatically reset the FPGA and continue operation
without restarting the controller. When this occurs,
LOG_ES_SFA7700_FPGA_RESET events will be logged. No action is required,
however please supply the event log to DDN support. [FPGA-45]
• FPGA version 1.14-0.40 resolves an issue where a SFA7700 cold start would
sometimes hang with no output. [FPGA-86]
5.0 Known Issues
5.1 Common
• The drive serial number reported in SHOW PD output may contain additional
