### LSI Firmware Phase

The following table summarizes LSI HBA firmware features by phase. A software release contains LSI firmware features for its designated phase and all previous phases. Software version 1.0 and 1.1 support LSI Firmware Phase 15.

Feature | Description
--- | ---
Firmware resource availability | Target-mode driver can determine available resources.
Support for increased SATA drive NCQ depth | Firmware can now utilize 16-command and 32-command queue depths on drives that support them.
Configure initial AWT advertised | Whenever the IOC attempts to open an end device or expander, the OPEN address frame contains an ARBITRATION WAIT TIME (AWT) value that is used to resolve deadlocks occurring when another device in the topology attempts to open the IOC at the same time. The initial value programmed into this field is now configurable using NVDATA.
Optionally disable phy lockup workaround | The phy lockup workaround periodically examines each direct-attached phy and resets the link if it detects that an in-progress data transfer has stalled for too long. Now, it is possible to disable the phy lockup workaround for direct-attached phys with end devices, expanders, or both (which effectively disables the workaround altogether).
Support for SATA SSDs | Support for solid state drives (SSDs) in RAID configurations in the same manner as magnetic media drives. SATA Only.
Enable/Disable Integrated RAID data scrub on SSDs | SSDScrubDisable flag (off by default) disables data scrub on RAID 1 and RAID 1E volumes consisting of SSDs.
Support for Sun StorageTek 2500 Series | Supports new CONNECTOR TYPE field in SMP DISCOVER Response
Increase minimum supported target ports to 2444 | Keeps 10 bus/target IDs reserved for foreign volumes. This increases the number of supported foreign volumes from 2 to 5 since foreign volumes can consume 2 bus/target IDs per volume.
